As a user of npm-hosted packages in my own projects, I'm not really sure what to do to protect myself. It's not feasible for me to audit every single one of my dependencies, and every one of my dependencies' dependencies, and so on. Even if I had the time to do that, I'm not a typescript/javascript expert, and I'm certain there are a lot of obfuscated things that an attacker could do that I wouldn't realize was embedded malware.
One thing I was thinking of was sort of a "delayed" mode to updating my own dependencies. The idea is that when I want to update my dependencies, instead of updating to the absolute latest version available of everything, it updates to versions that were released no more than some configurable amount of time ago. As a maintainer, I could decide that a package that's been out in the wild for at least 6 weeks is less likely to have unnoticed malware in it than one that was released just yesterday.
Obviously this is not a perfect fix, as there's no guarantee that the delay time I specify is enough for any particular package. And I'd want the tool to present me with options sometimes: e.g. if my current version of a dep has a vulnerability, and the fix for it came out a few days ago, I might choose to update to it (better eliminate the known vulnerability than refuse to update for fear of an unknown one) rather than wait until it's older than my threshold.

I think Github's Dependabot can help you here. You can also host your own little instance of DependencyTrack and keep up to date with vulnerabilities.
> It's not feasible for me to audit every single one of my dependencies, and every one of my dependencies' dependencies
I think this is a good argument for reducing your dependency count as much as possible, and keeping them to well-known and trustworthy (security-wise) creators.
"Not-invented-here" syndrome is counterproductive if you can trust all authors, but in an uncontrolled or unaudited ecosystem it's actually pretty sensible.
Have we all forgotten the left-pad incident?
This is an eco system that has taken code reuse to the (unreasonable) extreme.
When JS was becoming popular, I’m pretty sure every dev cocked an eyebrow at the dependency system and wondered how it’d be attacked.
> This is an eco system that has taken code reuse to the (unreasonable) extreme.
Not even that actually. Actually the wheel is reinvented over and over again in this exact ecosystem. Many packages are low quality, and not even suitable to be reused much.
The perfect storm of on the one side junior developers who are afraid of writing even trivial code and are glad if there's a package implementing functionality that can be done in a one-liner, and on the other side (often junior) developers who want to prove themselves and think the best way to do that is to publish a successful npm package
The blessing and curse of frontend development is that there basically isn't a barrier to entry given that you can make some basic CSS/JS/HTML and have your browser render it immediately.
There's also the flavor of frontend developer that came from the backend and sneers at actually having to learn frontend because "it's not real development"
> There's also the flavor of frontend developer that came from the backend and sneers at actually having to learn frontend because "it's not real development"
What kind of code does this developer write?
As little code as possible to get the job done without enormous dependencies. Avoiding js and using css and html as much as possible.
Sounds like the perfect frontend dev to me.
The designer, the customer, and US/EU accessibility laws heavily disagree.
The designer already disagrees with accessibility laws. Contrast is near zero.
The designer wants huge amounts of screen space wasted on unnnecessary padding, massive Fisher-Price rounded corners, and fancy fading and sliding animations that get in the way and slow things down. (Moreover, the designer just happens to want to completely re-design everything a few months later.)
The customer “ooh”s and “aah”s at said fancy animations running on the salesman’s top of the line macbook pro and is lured in, only realising too late that they’ve been bitten in the ass by the enormous amount of bloat that makes it run like a potato on any computer that costs less than four thousand dollars.
And US/EU laws are written by clueless bureaucrats whose most recent experience with technology is not even an electric typewriter.
What’s your point?
How is javascript required for accessibility? I wasn’t aware of that.
It is not. In fact, it is all the modern design sensibilities and front-end frameworks that make it nearly impossible to make accessible things.
We once had the rule HTML should be purely semantic and all styling should be in CSS. It was brilliant, even though not everything looked as fancy as today.
A11y is mostly handled by just using semantic html.
The designer, in my experience, is totally fine with just using a normal select element, they don't demand that I reinvent the drop-down with divs just to put rounded corners on the options.
Nobody cares about that stuff. These are minor details, we can change it later if someone really wants it. As long as we're not just sitting on our hands for lack of work I'm not putting effort into reinventing things the browser has already solved.
Usually they write only prompts and then accept whatever is generated, ignoring all typing and linting issues
Prompts? React and Angular came out over 10 years ago. The left pad incident happened in 2016.
Let me assure you, devs were skeptical about all this well before AI.
People pushing random throwaway packages is not the issue.
A lot of the culture is built by certain people who make a living out of package maximalism.
More packages == more eyballs == more donations.
They have an agenda that small packages are good and made PRs into popular packages to inject their junk into the supply chain.
I found it funny back when people were abandoning Java for JavaScript thinking that was better somehow...(especially in terms of security)
NPM is good for building your own stack but it's a bad idea (usually) to download the Internet. No dep system is 100% safe (including AI, generating new security vulns yay).
I'd like to think that we'll all stop grabbing code we don't understand and thrusting it into places we don't belong, or at least, do it more slowly, however, I also don't have much faith in the average (especially frontend web) dev. They are often the same idiots doing XYZ in the street.
I predict more hilarious (scary even) kerfuffles, probably even major militaries losing control of things ala Terminator style.
It’s not clear to me what this has to do with Java vs JavaScript (unless you’re referring to the lack of a JS standard library which I think will pretty much minimize this issue).
In fact, when we did have Java in the browser it was loaded with security issues primarily because of the much greater complexity of the Java language.
Java has maven, and is far from immune from similar types of attacks. However, it doesn't have the technological monstrosity named NPM. In fact that aforementioned complexity is/was an asset in raising the bar, however slightly, in producing java packages. Crucially, that ecosystem is nowhere near as absurdly complex (note, I'm ignoring the I'll fated cousin that is Gradle, and is also notorious for being a steaming pile of barely-working inscrutable dependencies)
Anyways, I think you are missing the forest for the trees if you think this is a Java vs JavaScript comparison, don't worry it's also possible to produce junk enterprise code too...
Just amusing watching people be irrationally scared of one language/ecosystem vs another without stopping to think why or where the problems are coming from.
It's not the language it's the library that's not designed to isolate untrusted code from the start. Much harder to exit the sandbox if your only I/O mechanism is the DOM, alert() and prompt().
And the whole rest of the Internet...
The issue here is not Java or it's complexity. The point is also not Java, it's incidental that it was popular at the time. It's people acting irrationally about things and jumping ship for an even-worse system.
Like, yes, if that really were the whole attack surface of JS, sure nobody would care. They also wouldn't use it...and nothing we cared about would use it either...
In that era JavaScript was also loaded with security issues. That's why browsers had to invest so much in kernel sandboxing. Securing JavaScript VMs written by hand in C++ is a dead end, although ironically given this post, it's easier when they're written in Java [1]
But the reason Java is more secure than JavaScript in the context of supply chain attacks is fourfold:
1. Maven packages don't have install scripts. "Installing" a package from a Maven repository just means downloading it to a local cache, and that's it.
2. Java code is loaded lazily on demand, class at a time. Even adding classes to a JAR doesn't guarantee they'll run.
3. Java uses fewer, larger, more curated libraries in which upgrades are a more manual affair involving reading the release notes and the like. This does have its downsides: apps can ship with old libraries that have unfixed bugs. Corporate users tend to have scanners looking for such problems. But it also has an upside, in that pushing bad code doesn't immediately affect anything and there's plenty of time for the author to notice.
4. Corporate Java users often run internal mirrors of Maven rather than having every developer fetch from upstream.
The gap isn't huge: Java frameworks sometimes come with build system plugins that could inject malware as they compile the code, and of course if you can modify a JAR you can always inject code into a class that's very likely to be used on any reasonable codepath.
But for all the ragging people like to do on Java security, it was ahead of its time. A reasonable fix for these kind of supply chain attacks looks a lot like the SecurityManager! The SecurityManager didn't get enough adoption to justify its maintenance costs and was removed, partly because of those factors above that mean supply chain attacks haven't had a significant impact on the JVM ecosystem yet, and partly due to its complexity.
It's not clear yet what securing the supply chain in the Java world will look like. In-process sandboxing might come back or it might be better to adopt a Chrome-style microservice architecture; GraalVM has got a coarser-grained form of sandboxing that supports both in-process and out-of-process isolation already. I wrote about the tradeoffs involved in different approaches here:

If it's not feasible to audit every single dependency, it's probably even less feasible to rewrite every single dependency from scratch. Avoiding that duplicated work is precisely why we import dependencies in the first place.
Most dependencies do much more than we need from them. Often it means we only need one or a few functions from them. This means one doesn't need to rewrite whole dependencies usually. Don't use dependencies for things you can trivially write yourself, and use them for cases where it would be too much work to write yourself.
A brief but important point is that this primarily holds true in the context of rewriting/vendoring utilities yourself, not when discussing importing small vs. large dependencies.
Just because dependencies do a lot more than you need, doesn't mean you should automatically reach for the smallest dependency that fits your needs.
If you need 5 of the dozens of Lodash functions, for instance, it might be best to just install Lodash and let your build step shake out any unused code, rather than importing 5 new dependencies, each with far fewer eyes and release-management best practices than the Lodash maintainers have.
The argument wasn’t to import five dependencies, one for each of the functions, but to write the five functions yourself. Heck, you don’t even need to literally write them, check the Lodash source and copy them to your code.
This might be fine for some utility functions which you can tell at a glance have no errors, but for anything complex, if you copy you don't get any of the bug/security fixes that upstream will provide automatically. Oh, now you need a shim of this call to work on the latest Chrome because they killed an api- you're on your own or you have to read all of the release notes for a dependency you don't even have! But taking a dependency on some other library is, as you note, always fraught. Especially because of transitive dependencies, you end up having quite a target surface area for every dep you take.
Whether to take a dependency is a tricky thing that really comes down to engineering judgement- the thing that you (the developer) are paid to make the calls on.
The massive amount of transitive dependencies is exactly the problem with regard to auditing them. There are successful businesses built solely around auditing project dependencies and alerting teams of security issues, and they make money at all because of the labor required to maintain this machine.
It’s not even a judgement call at this point. It’s more aligned with buckling your seatbelt, pointing your car off the road, closing your eyes, flooring it and hoping for a happy ending.
And then when node is updated and natively supports set intersections you would go back to your copied code and fix it?
If it works, why do so? Unless there's a clear performance boost, and if so you already know the code and can quickly locate your interpreted version.
Or At the time of adding you can add a NOTE or FIXME comment stating where you copied it from. A quick grep for such keyword can give you a nice overview of nice to have stuff. You can also add a ticket with all the details if you're using a project management tool and resuscitate it when that hypothetical moment happens.
You have obviously never checked the Lodash source.
I think the level of protection you get from that depends on how the unused code detection interacts with whatever tricks someone is using for malicious code.
Yes, fewer, larger, trustworthy dependencies with tree shaking is the way to go if you ask me.
Almost like a standard library..
I wanted to make a joke about
…but double checked before and @stdlib/stdlib has 58 dependencies, so the joke preempted me.Yeah, but perhaps we could have different flavors. If you like functional style you could have a very functional standard library that doesn't mutate anything, or if you like object oriented stuff you could have classes of object with methods that mutate themselves. And the Typescript folks could have a strongly typed library.
I agree with this but the problem is that a lot of the extra stuff dependencies do is indeed to protect from security issues.
If you’re gonna reimplement only thr code you need from a dependency, it’s hard to know of the stuff you’re leaving out how much is just extra stuff you don’t need and how much might be security fixes that may not be apparent to you but the dependency by virtue of being worked upon and used by many people has fixed.
I'm using LLMs to write stuff that would normally be in dependencies, mostly because I don't want to learn how to use the dependency, and writing a new one from scratch is really easy with LLMs.
Age of bespoke software is here. Did you have any hard to spot non-obvious bugs in these code units?
It isn't feasible to audit every line of every dependency, just as it's not possible to audit the full behavior of every employee that works at your company.
In both cases, the solution is similar: try to restrict access to vital systems only to those you trust,so that you have less need to audit their every move.
Your system administrators can access the server room, but the on-site barista can't. Your HTTP server is trusted enough to run in prod, but a color-formatting library isn't.
> It isn't feasible to audit every line of every dependency, just as it's not possible to audit the full behavior of every employee that works at your company.
Your employees are carefully vetted before hiring. You've got their names, addresses, and social security numbers. There's someone you're able to hold accountable if they steal from you or start breaking everything in the office.
This seems more like having several random contractors who you've never met coming into your business in the middle of night. Contractors that were hired by multiple anonymous agencies you just found online somewhere with company names like gkz00d or 420_C0der69 who you've also never even spoken to and who have made it clear that they can't be held accountable for anything bad that happens. Agencies that routinely swap workers into or out of various roles at your company without asking or telling you, so you don't have any idea who the person working in the office is, what they're doing, or even if they're supposed to be there.
"To make thing easier for us we want your stuff to require the use of a bunch of code (much of which does things you don't even need) that we haven't bothered looking at because that'd be too much work for us. Oh, and third parties we have no relationship with control a whole bunch of that code which means it can be changed at any moment introducing bugs and security issues we might not hear about for months/years" seems like it should be a hard sell to a boss or a client, but it's sadly the norm.
Assuming that something is going to go wrong and trying to limit the inevitable damage is smart, but limiting the amount of untrustworthy code maintained by the whims of random strangers is even better. Especially when the reasons for including something that carries so much risk is to add something trivial or something you could have just written yourself in the first place.
That hit much too close to reality. It's exactly like that. Even the names were spot on!

Sounds very similar to how global SIs staff enterprise IT contracts.
This is true to the extent that you actually _use_ all of the features of a dependency.
You only need to rewrite what you use, which for many (probably most) libraries will be 1% or less of it
Indeed. About 26% of the disk space for a freshly-installed copy of pip 25.2 for Python 3.13 comes from https://pypi.org/project/rich/ (and its otherwise-unneeded dependency https://pypi.org/project/Pygments/), "a Python library for rich text and beautiful formatting in the terminal", hardly any of the features of which are relevant to pip. This is in spite of an apparent manual tree-shaking effort (mostly on Pygments) — a separate installed copy of rich+Pygments is larger than pip. But even with that attempt, for example, there are hundreds of kilobytes taken up for a single giant mapping of "friendly" string names to literally thousands of emoji.
Another 20% or more is https://pypi.org/project/requests/ and its dependencies — this is an extremely popular project despite that the standard library already provides the ability to make HTTPS connections (people just hate the API that much). One of requests' dependencies is certifi, which is basically just a .pem file in Python package form. The vendored requests has not seen any tree-shaking as far as I can tell.
This sort of thing is a big part of why I'll be able to make PAPER much smaller.
What paper?
Presumably this: https://github.com/zahlman/paper
> If it's not feasible to audit every single dependency, it's probably even less feasible to rewrite every single dependency from scratch.
There is no need to rewrite dependencies. Sometimes it just so happens that a project can live without outputting fancy colorful text to stdout, or doesn't need to spread transitive dependencies on debug utilities. Perhaps these concerns should be a part of the standard library, perhaps these concerns are useless.
And don't get me started on bullshit polyfill packages. That's an attack vector waiting to be exploited.
Not sure I completely agree as you often use only a small part of a library
One interesting side effect of AI is that it makes it sometimes easy to just recreate the behavior, perhaps without even realizing it..
is it that infeasible with LLMs?
a lor of these dependencies are higher order function definitions, which never change, and could be copy/pasted around just fine. they're never gonna change
Its much more feasible these days. These days for my personal projects I just have CC create only a plain html file with raw JS and script links.
it's probably even less feasible to rewrite every single dependency from scratch.
When you code in a high-security environment, where bad code can cost the company millions of dollars in fines, somehow you find a way.
The sibling commenter is correct. You write what you can. You only import from trusted, vetted sources.
"rewrite every single dependency from scratch"
No need to. But also no need to pull in a dependency that could be just a few lines of own (LLM generated) code.
>>a few lines of own (LLM generated) code.
... and now you've switched the attack vector to a hostile LLM.
Sure but that's a one time vector. If the attacker didn't infiltrate the LLM before it generated the code, then the code is not going to suddenly go hostile like an npm package can.
I did not say to do blind copy paste.
A few lines of code can be audited.
Though you will see the code at least, when you are copy pasting it and if it is really only a few lines, you may be able to review it. Should review it of course.
If it's that little review the dependency.
The difference is, the dependency can change and is usually way harder to audit. Subfolders in subfolder, 2 lines here in a file, 3 line there vs locking at some files and check what they do.
Sounds like the job for an LLM tool to extract what's actually used from appropriately-licensed OSS modules and paste directly into codebases.
Requiring you to audit both security and robustness on the LLM generated code.
Creating two problems, where there was one.
I didn't say generate :) - in all seriousness, I think you could reasonably have it copy the code for e.g. lodash.merge() and paste it into your codebase without the headaches you're describing. IMO, this method would be practical for a majority of npm deps in prod code. There are some I'd want to rely on the lib (and its maintenance over time), but also... a sort function is a sort function.
LLMs don't copy and paste. They ingest and generate. The output will always be a generated something.
In 2022, sure. But not today. Even something as simple as generating and running a `git clone && cp xyz` command will create code not directly generated by the LLM.
LLMs can do the audits now.
Do you have any evidence it wouldn't just make up code.
This is already a thing, compiled languages have been doing this for decades. This is just C++ templates with extra steps.
>> and keeping them to well-known and trustworthy (security-wise) creators.
The true threat here isn't the immediate dependency though, it's the recursive supply chain of dependencies. "trustworthy" doesn't make any sese either when the root cause is almost always someone trustworthy getting phished. Finally if I'm not capable of auditing the dependencies it's unlikely I can replace them with my own code. That's like telling a vibe coder the solution to their brittle creations is to not use AI and write the code themselves.
> Finally if I'm not capable of auditing the dependencies it's unlikely I can replace them with my own code. That's like telling a vibe coder the solution to their brittle creations is to not use AI and write the code themselves.
In both cases, actually doing the work and writing a function instead of adding a dependency or asking an AI to write it for you will probably make you a better coder and one who is better able to audit code you want to blindly trust in the future.
"A little copying is better than a little dependency" -- Go proverb (also applies to other programming languages)
> I think this is a good argument for reducing your dependency count as much as possible, and keeping them to well-known and trustworthy (security-wise) creators.
I wonder to which extent is the extreme dependency count a symptom of a standard library that is too minimalistic for the ecosystem's needs.
Perhaps this issue could be addressed by a "version set" approach to bundling stable npm packages.
I remember people in the JS crowd getting really mad at the implication that this all was pretty much inevitable, like 10/15 years ago. Can’t say they didn’t do great things since then, but it’s not like nobody saw this coming.
Exactly.
I always tried to keep the dependencies to a minimum.
Another thing you can do is lock versions to a year ago (this is what linux distros do) and wait for multiple audits of something, or lack of reports in the wild, before updating.
I saw one of those word-substition browser plugins a few years back that swapped "dependency" for "liability", and it was basically never wrong.
(Big fan of version pinning in basically every context, too)
I'm re-reading all these previous comments, replacing "dependency" for "liability" in my mind, and it's being quite fun to see how well everything still keeps meaning the same, but better
> sort of a "delayed" mode
That's the secret lots of enterprises have relied on for ages. Don't be bleeding edge, let the rest of the world gineau pig the updates and listen for them to sound the alarm if something's wrong. Obviously you do still need to pay attention to the occasional, major, hot security issues and deal with them in a swift fashion.
Another good practice is to control when your updates occur - time them when it's ok to break things and your team has the bandwidth to fix things.
This is why I laughed hard when Microsoft moved to aggressively push Windows updates and the inevitable borking it did to people's computers at the worst possible times ("What's that you said? You've got a multi-million dollar deliverable pitch tomorrow and your computer won't start due to a broken graphics driver update?). At least now there's a "delay" option similar to what you described, but it still riles me that update descriptions are opaque (so you can't selectively manage risk) and you don't really have the degree of control you ought to.
The article explicitly mentions a way to do this:
Use NPM Package Cooldown Check
The NPM Cooldown check automatically fails a pull request if it introduces an npm package version that was released within the organization’s configured cooldown period (default: 2 days). Once the cooldown period has passed, the check will clear automatically with no action required. The rationale is simple - most supply chain attacks are detected within the first 24 hours of a malicious package release, and the projects that get compromised are often the ones that rushed to adopt the version immediately. By introducing a short waiting period before allowing new dependencies, teams can reduce their exposure to fresh attacks while still keeping their dependencies up to date.
This attack was only targeting user environments.
Having secrets in a different security context, like root/secretsuser-owned secret files only accessible by the user for certain actions (the simplest way would be eg. sudoers file white listing a precise command like git push), which would prevent arbitrary reads of secrets.
The other part of this attack, creating new github actions, is also a privilege, normal users dont need to exercise that often or unconstrained. There are certainly ways to prevent/restrict that too.
All this "was a supply chain attack" fuzz here is IMO missing the forest for the trees. Changing the security context for these two actions is easier to implement than supply chain analysis and this basic approach is more reliable than trusting the community to find a backdoor before you apply the update. Its security 101. Sure, there are post-install scripts that can attack the system but that is a whole different game.
This is basically what I recommended people do with windows updates back when MS gave people a choice about when/if to install them, with shorter windows for critical updates and much longer ones for low priority updates or ones that only affected things they weren't using.
And hope there isn’t some recently patched zero-day RCE exploit at the same time.
That's a feature of stepsecurity though, it's not built-in.
Personally, I go further than this and just never update dependencies unless the dependency has a bug that affects my usage of it. Vulnerabilities are included.
It is insane to me how many developers update dependencies in a project regularly. You should almost never be updating dependencies, when you do it should be because it fixes a bug (including a security issue) that you have in your project, or a new feature that you need to use.
The only time this philosophy has bitten me was in an older project where I had to convince a PM who built some node project on their machine that the vulnerability warnings were not actually issues that affected our project.
Edit: because I don't want to reply to three things with the same comment - what are you using for dependencies where a) you require frequent updates and b) those updates are really hard?
Like for example, I've avoided updating node dependencies that have "vulnerabilities" because I know the vuln doesn't affect me. Rarely do I need to update to support new features because the dependency I pick has the features I need when I choose to use it (and if it only supports partial usage, you write it yourself!). If I see that a dependency frequently has bugs or breakages across updates then I stop using it, or freeze my usage of it.
Then you run the risk of drifting so much behind that when you actually have to upgrade it becomes a gargantuan task. Both ends of the scale have problems.
That's why there's an emphasis on stability. If things works fine, don't change. If you're applying security patches, don't break the API.
In NPM world, there's so much churn that it would be comical if not for the security aspects.
That's only a problem for you, the developer, though, and is merely an annoyance about time spent. And it's all stuff you had to do anyway to update--you're just doing it all at once instead of spread out over time. A supply chain malware attack is a problem for every one of your users--who will all leave you once the dust is settled--and you end up in headline news at the top of HN's front page. These problems are not comparable. One is a rough day. The other is the end of your project.
The time upgrading is not linear, it’s exponential. If it hurts, do it more often! https://martinfowler.com/bliki/FrequencyReducesDifficulty.ht...
counterpoint, if the runtime itself (nodejs) has a critical issue, you haven't updated for years, you're on an end-of-life version, and you cannot upgrade because you have dependencies that do not support the new version of the runtime, you're in for a painful day. The argument for updating often is that when you -are- exposed to a vulnerability that you need a fix for, it's a much smaller project to revert or patch that single issue.
Otherwise, I agree with the sentiment that too many people try to update the world too often. Keeping up with runtime updates as often as possible (node.js is more trusted than any given NPM module) and updating only when dependencies are no longer compatible is a better middle ground.
The same logic you used for runtimes also applies to libraries. Vulnerabilities are found in popular JS libraries all the time. The surface area is, of course, smaller than that of a runtime like Node.js, but there is still lots of potential for security issues with out-of-date libraries.
There really is no good solution other than to reduce the surface area for vulnerabilities by reducing the total amount of code you depend on (including third-party code). In practice, this means using as few dependencies as possible. If you only use one or two functions from lodash or some other helper library, you're probably better off writing or pulling in those functions directly instead.
Fully disagree. The problem is that when you do need to upgrade, either for a bug fix, security fix, or new feature that you need/want, it's a lot easier to upgrade if your last upgrade was 3 months ago than if it was 3 years ago.
This has bitten me so many times (usually at large orgs where policy is to be conservative about upgrades) that I can't even consider not upgrading all my dependencies at least once a quarter.
yeah, I typically start any substantial development work with getting things up to date so you're not building on something you'll find out is already broken when you do get around to that painful upgrade.
That works fine if you have few dependencies (obviously this is a good practice) and you have time to vet all updates and determine whether a vulnerability impacts your particular code, but that doesn’t scale if you’re a security organization at, say, a small company.
The problem here is that there might be a bug fix or even security fix that is not backported to old versions, and you suddenly have to update to a much newer version in a short time
this seems to me to be trading one problem that might happen for one that is guaranteed: a very painful upgrade. Maybe you only do it once in a while but it will always suck.
Dependency hell exists at both ends. Too quick can bite you just as much as being too slow/lazy.
> sort of a "delayed" mode to updating my own dependencies. The idea is that when I want to update my dependencies, instead of updating to the absolute latest version available of everything, it updates to versions that were released no more than some configurable amount of time ago.
For Python's uv, you can do something like:
> uv lock --exclude-newer $(date --iso -d "2 days ago")
oh that uv lock is neat, i am going to give that a go
Awesome tip, thanks!
You can switch to the mentioned "delayed" mode if you're using pnpm. A few days ago, pnpm 10.16 introduced a minimumReleaseAge setting that delays the installation of newly released dependencies by a configurable amount of time.
https://pnpm.io/blog/releases/10.16
pnpm just added this: https://pnpm.io/blog/releases/10.16
This sounds nice in theory, but does it really solve the issue? I think that if no one's installing that package then no one is noticing the malware and no one is reporting that package either. It merely slightly improves the chances that author would notice a version they didn't release, but this doesn't work if author is not particularly actively working the compromised project.
These days compromised packages are often detected automatically by software that scans all packages uploaded to npm like https://socket.dev or https://snyk.io. So I imagine it's still useful to have those services scan these packages first, before they go out to the masses.
Measures like this also aren't meant to be "final solutions" either, but stop-gaps. Slowing the spread can still be helpful when a large scale attack like this does occur. But I'm also not entirely sure how much that weighs against potentially slowing the discovery as well.
Ultimately this is still a repository problem and not a package manager one. These are merely band-aids. The responsibility lies with npm (the repository) to implement proper solutions here.
> The responsibility lies with
No, it doesn't solve the issue, but it probably helps.
And I agree that if everyone did this, it would slow down finding issues in new releases. Not really sure what to say to that... aside from the selfish idea that if I do it, but most other people don't, it won't affect me.
there's apparently an npm RFC from 2022 proposing a similar (but potentially slightly better?) solution https://github.com/npm/rfcs/issues/646
bun is also working on it: https://github.com/oven-sh/bun/issues/22679
Aren't they found quickly because people upgrade quickly?
minimumReleaseAge is pretty good! Nice!!
I do wish there were some lists of compromised versions, that package managers could disallow from.
this btw would also solve social media. if only accounts required a month waiting period before they could speak.
Not you. But one would expect major cybersecurity vendors such as Crowdstrike to screen their dependencies, yet they are all over the affected list.
pnpm just added minimum age for dependencies https://pnpm.io/blog/releases/10.16#new-setting-for-delayed-...
From your link:
> In most cases, such attacks are discovered quickly and the malicious versions are removed from the registry within an hour.
By delaying the infected package availability (by "aging" dependencies), we're only delaying the time, and reducing samples, until it's detected. Infections that lay dormant are even more dangerous than explosives ones.
The only benefit would be if, during this freeze, repository maintainers were successfully pruning malware before it hits the fan, and the freeze would give scanners more time to finish their verification pipelines. That's not happening afaik, NPM is crazy fast going from `npm publish` to worldwide availability, scanning is insufficient by many standards.
Afaict many of these recent supply chain attacks _have_ been detected by scanners. Which ones flew under the radar for an extended period of time?
From what I can tell, even a few hours of delay for actually pulling dependencies post-publication to give security tools a chance to find it would have stopped all (?) recent attacks in their tracks.
Thank god, adopting this immediately. Next I’d like to see Go-style minimum version selection instead.
Oh brilliant. I've been meaning to start migrating my use to pnpm; this is the push I needed.
I think it definitely couldn’t hurt. You’re right it doesn’t eliminate the threat of supply chain attacks, but it would certainly reduce them and wouldn’t require much effort to implement (either manually or via script). You’re basically giving maintainers and researchers time to identify new malware and patch or unrelease them before you’re exposed. Just make sure you still take security patches.
Use less dependencies :)
And larger dependencies that can be trusted in larger blocks. I'll bet half of a given projects dependencies are there to "gain experience with" or be able to name drop that you've used them.
Less is More.
We used to believe that. And then W3C happened.
When using Go, you don't get updated indirect dependencies until you update a direct dependency. It seems like a good system, though it depends on your direct dependencies not updating too quickly.
The auto-updating behaviour dependencies because of the `^` version prefix is the root problem.
It's best to never use `^` and always specify exact version, but many maintainers apparently can't be bothered with updating their dependencies themselves so it became the default.
> One thing I was thinking of was sort of a "delayed" mode to updating my own dependencies.
You can do this with npm (since version 6.9.0).
To only get registry deps that are over a week old:

Maybe one approach would be to pin all dependencies, and not use any new version of a package until it reaches a certain age. That would hopefully be enough time for any issues to be discovered?
People living on the latest packages with their dependabots never made any sense to me, ADR. They trusted their system too much
If you don't review the pinned versions, it makes no difference.
Packages can still be updated, even if pinned. If a dependency of a dependency is not pinned - it can still be updated.
Stick to (pin) old stable versions, don't upgrade often. Pain in the butt to deal with eventual minimum-version-dependency limitations, but you don't get the brand new releases with bugs. Once a year, get all the newest versions and figure out all the weird backwards-incompatible bugs they've introduced. Do it over the holiday season when nobody's getting anything done anyway.
I like to pin specific versions in my package.json so dependencies don't change without manual steps, and use "npm ci" to install specifically the versions in package-lock.json. My CI runs "npm audit" which will raise the alarms if a vulnerability emerges in those packages. With everything essentially frozen there either is malware within it, or there is not going to be, and the age of the packages softly implies there is not.
This is where distributed code audits come in, you audit what you can, others audit what they can, and the overlaps of many audits gives you some level of confidence in the audited code.

> instead of updating to the absolute latest version available of everything, it updates to versions that were released no more than some configurable amount of time ago
The problem with this approach is you need a certain number of guinea pigs on the bleeding edge or the outcome is the same (just delayed). There is no way for anyone involved to ensure that balance is maintained. Reducing your surface area is a much more effective strategy.
Not necessarily, some supply chain compromises are detected within a day by the maintainers themselves, for example by their account being taken over. It would be good to mitigate those at least.
In that specific scenario, sure; but I don't think that's a meaningful guardrail for a business.
I recently started using npm for an application where there’s no decent alternative ecosystem.
The signal desktop app is an electron app. Presumably it has the same problem.
Does anyone know of any reasonable approaches to using npm securely?
“Reduce your transitive dependencies” is not a reasonable suggestion. It’s similar to “rewrite all the Linux kernel modules you need from scratch” or “go write a web browser”.
Most big tech companies maintain their own NPM registry that only includes approved packages. If you need a new package available in that registry you have to request it. A security team will then review that package and its deps and add it to the list of approved packages…
I would love to have something like that "in the open"…
A debian version of NPM? I've seen a lot of hates on Reddit and other places about Debian because the team focuses on stability. When you look at the project, it's almost always based on Rust or Python.
> “Reduce your transitive dependencies” is not a reasonable suggestion. It’s similar to “rewrite all the Linux kernel modules you need from scratch” or “go write a web browser”.
Oh please, do not compare writing bunch of utilities for you "app" with writing a web browser.
npm shrinkwrap and then check in your node_modules folder. Don't have each developer (or worse, user) individually run npm install.
It's common among grizzled software engineering veterans to say "Check in the source code to all of your dependencies, and treat it as if it were your own source code." When you do that, version upgrades are actual projects. There's a full audit trail of who did what. Every build is reproducible. You have full visibility into all code that goes into your binary, and you can run any security or code maintenance tools on all of it. You control when upgrades happen, so you don't have a critical dependency break your upcoming project.
I update my deps once a year or when I specifically need to. That helps a bit. Though it upsets the security theatre peeps at work who just blindly think dependabot issues means I need to change dependencies.
>It's not feasible for me to audit every single one of my dependencies
Perhaps I’m just ignorant of web development, but why not? We do so with our desktop software.
Average .net core desktop complex app may have a dozen dependencies if it get to that point. Average npm todo list may have several thousand if not more
Don't update your dependencies manually. Setup renovate to do it for you, with a delay of at least a couple of weeks, and enable vulnerability alerts so that it opens PRs for publicly known vulnerabilities without delay

Depending on a commercial service is out of the question for most open source projects.
Renovate is not commercial, it's an own source dependabot, quite more copable at that.
AGPL is a no-go for many companies (even when it's just a tool that touches your code and not a dependency you link to).
Lot of software has update policies like this and then also people will run a separate test environment updating to latest
Install less dependencies, code more.
Sure, and I do that whenever I can. But I'm not going to write my own react, or even my own react-hook-form. I'm not going to rewrite stripe-js. Looking through my 16 direct dependencies -- that pull in a total of 653 packages, jesus christ -- there's only one of them that I'd consider writing myself (js-cookie) in order to reduce my dependency count. The rest would be a maintenance burden that I shouldn't have to take on.
There's this defense mechanism that I don't know how it's called, but when someone takes a criticism to the extreme to complain about it being unfeasible.
Criticism: "You should shower every day"
Defense: "OH, maybe I should shower every hour, to the point where my skin dries and I can't get my work done because I'm in the shower all day."
No, there's a pretty standard way of doing things that you can care to learn, and it's very feasible, people shower every day during the week, sometimes they skip if they don't go out during weekends, if it's very cold you can skip a day, and if it's hot you can even shower twice. You don't even need to wash your hair every day. There's nuance that you can learn if you stop being so defeatist about it.
Similarly, you can of course install stripe-js since it's vendored from a paid provider with no incentive to fuck you with malware and with resources to audit dependency code, at any rate they are already a dependency of yours, so adding an npm package does not add a vendor to your risk profile.
Similarly you can add react-hook-form if it's an official react package, however if it isn't, then it's a risk, investigate who uploads it, if it's a random from github with an anime girl or furry image in their profile, maybe not. Especially if the package is something like an unofficial react-mcp-dotenv thing where it has access to critical secrets.
Another fallacy is that you have to rewrite the whole dependency you would otherwise import. False. You are not going to write a generic solution for all use cases, just for your own, and it will be tightly integrated and of higher quality and less space (which helps with bandwidth, memory and CPU caching), because of it. For god's sake, you used an example relating to forms? We've had forms since the dot com boom, how come you are still having trouble with those? You should know them like the back of your hand.
Reductio ad Absurdum may be what you're thinking of, but Straw Man might also apply. Funny enough the responder didn't actually do what you said. They stated of the 600+ dependencies they counted there was only one they felt comfortable implementing themselves. Your accusation of them taking your statement to the extreme is reverse straw man rhetoric; you're misrepresenting their argument as extreme or absurd when it’s actually not.
Reductio ad Absurdum is not a fallacy but a legitimate rhetorical technique where you can point out obvious flaws in logic by taking that logic and applying it to something that people would find ridiculous. Note that this is not the most 'extreme' version, it is the same version, using the same logic.
Example:
Argument: People should be able to build whatever they want on their own property.
Reductio ad Absurdum position: I propose to build the world's largest Jenga tower next to your house.
Note that this does not take into account any counter arguments such as 'if it falls on me you will still be liable for negligence', but it makes a point without violating the logic of the original argument. To violate that logic would indeed be a straw man.
React has zero dependencies and Stripe has one... What else do you need?
Copy-paste more.
I guess this is a joke, but imo it shouldn't be.
Not entirely a joke actually. For example, I have worked at a large corp where dependencies were high discouraged. For example lodash was not used in the codebase I was working on and if you really needed something from lodash you were encouraged to copy-paste the function. This won't work for large libraries of course but the copy-paste-first mentality is not a bad one.
I'm all for disregarding DRY and copypasting code you wrote.
But I think for untrusted third party code, it's much better to copy the code by hand, that way you are really forced to audit it. There really isn't much of an advantage to copying an install.sh script compared to just downloading a running the .sh, whereas writing the actual .sh commands on the command line (and following any other URLs before executing them) is golden.
If you pull something into your project, you're responsible for it working. Full stop. There are a lot of ways to manage/control dependencies. Pick something that works best for you, but be aware, due diligence, like maintenance is ultimately your responsibility.
Oh I'm well aware, and that's the problem. Unfortunately none of the available options hit anything close to the sweet spot that makes me comfortable.
I don't think this is a particularly unreasonable take; I'm a relative novice to the JS ecosystem, and I don't feel this uncomfortable taking on dependencies as I do in pretty much any other ecosystem I participate in, even those (like Rust) where the dependency counts can be high.
Acknowledging your responsibility doesn't make the problem go away. It's still better to have extra layers of protection.
I acknowledge that it is my responsibility to drive safely, and I take that responsibility seriously. But I still wear a seat belt and carry auto insurance.
That's very naive. We can do better than this.
Almost all software has a no warranty clause. I am not a lawyer but in pretty plain English every piece of software I have ever used has said exactly that I can fuck off if I expect it to work or do anything.
To clarify - I dont think it is naive to assume the software is as-is with all responsibilities on the user since that is exactly what lawyers have made all software companies say that for over 50 years.
Product liability is coming for software. Warranty disclaimers in licenses will be rendered ineffective by the end of 2026 at the latest.
this seems highly unlikely. Almost all of the software we're discussing in this context has little or no resources behind it. No lawyers are going to sue an OSS developer because there's no payday.
Source? An open source library is not necessarily a ‘product’ at all.
No source because it's not real. There's talk about final products and making the companies selling them responsible. But open source developers are not responsible.
only if you pay for it… otherwise you are liable but don't have anyone else to blame.
I'm not sure what your point is. I was saying it's naive to think that everyone is going to review all dependencies, and we can do better than requiring them to.
I thought my point was clearly made the 1st time.
How can we promise to "do better" when shit like "no author or distributor accepts responsibility to anyone for the consequences of using it or for whether it serves any particular purpose or works at all" is in the legal agreement of the software you are using?
Making someone agree to that while simultaneously on the side making promises that the software works is used car salesman gimmicks. The only things that matters is what you put in writing.
> How can we promise to "do better" when shit like "no author or distributor accepts responsibility to anyone
One way or another that will end.
Free Software will have the same responsibilities. If you write software, negligently, and it causes damage, you will be liable
I should not be able to make a Crypto wallet that is easy to hack and distribute it without consequence
This will be a very good thing
We know how to make secure 4eliable software (some of us) but nobody will pay for it
This happens because there's no auditing of new packages or versions. The distro's maintainer and the developer is the same person.
The general solution is to do what Debian does.
Keep a stable distro where new packages aren't added and versions change rarely (security updates and bugfixes only, no new functionality). This is what most people use.
Keep a testing/unstable distro where new packages and new versions can be added, but even then added only by the distro maintainer, NOT by the package developers. This is where the audits happen.
NPM, Python, Rust, Go, Ruby all suffer from this problem, because they have centralized and open package repositories.
> The general solution is to do what Debian does.
The problem with this approach is that frameworks tend to "expire" pretty quickly and you can't run anything for too long on Debian until the framework is obsolete. What I mean by obsolete is Debian 13 ships with Golang 1.24, A year from now it's gonna be Golang 1.26 - that is not being made available in trixie. So you have to find an alternative source for the latest golang deb. Same with PHP, Python etc. If you run them for 3 years with no updated just some security fixes here and there, you're gonna wake up in a world of hurt when the next stable release comes out and you have to do en-masse updates that will most likely require huge refactoring because syntax, library changes and so on.
And Javascript is a problem all by itself where versions come up every few months and packages are updated weekly or monthly. You can't run any "modern" app with old packages unless you accept all the bugs or you put in the work and fix them.
I am super interested in a solution for this that provides some security for packages pushed to NPM (the most problematic repository). And for distributions to have a healthy updated ecosystem of packages so you don't get stuck who knows for how long on an old version of some package.
And back to Debian, trixie ships with nginx 1.26.3-3+deb13u1. Why can't they continuously ship the latest stable version if they don't want to use the mainline one?
This is a culture issue with developers who find it OK to have hundreds of (transitive) dependencies, and then follow processes that, for all intents and purposes, blindly auto update them, thereby giving hundreds of third-parties access to their build (or worse) execution environments.
Adding friction to the sharing of code doesn't absolve developers from their decision to blindly trust a ridiculous amount of third-parties.
I find that the issue is much more often not updating dependencies often enough with known security holes, than updating too often and getting hit with a supply-chain malware attack.
There have been several recent supply chain attacks that show attackers are taking advantage of this (previously sensible) mentality. So it is time to pivot and come up with better solutions before it spirals out of control.
A model that Linux distros follow would work to an extent: you have developed of packages and separate maintainers who test and decide to include or exclude packages and versions of packages. Imagine a JS distro which includes the top 2000 most popular libraries that are all known to work with each other. Your project can pull in any of these and every package is cryptographically signed off on by both the developers and the maintainer.
Vulnerabilities in Linux distro packages obviously happen. But a single developer cannot push code directly into for example Debian and compromise the world.
Not updating is the other side of the same problem: library owners feel it is ok to make frequent backwards-compatibility breaking changes, often ignoring semver conventions. So consumers of their libraries are left with the choice to pin old insecure versions or spend time rewriting their code (and often transitive dependency code too) to keep up.
This is what happens when nobody pays for anything and nobody feels they have a duty to do good work for free.
>This is what happens when nobody pays for anything and nobody feels they have a duty to do good work for free.
Weirdly, some of the worst CVE I can think of were with enterprize software.
That's because there many people don't feel like it is their duty to do good work, even though they are paid ...
Who do you mean with "many people"? Developers who do not care or middle management that oversold features and overcommitted w.r.t. deadlines? Or both? Someone else?
It's not unreasonable to trust large numbers of trustworthy dependency authors. What we lack are the institutions to establish trust reliably.
If packages had to be cryptographically signed by multiple verified authors from a per-organization whitelist in order to enter distribution, that would cut down on the SPOF issue where compromising a single dev is enough to publish multiple malware-infested packages.
It IS unreasonable to trust individual humans across the globe in 100+ different jurisdictions pushing code that gets bundled into my application.
How can you guarantee a long trusted developer doesn't have a gun pointed to their head by their authoritarian govt?
In our B2B shop we recently implemented a process where developers cannot add packages from third party sources - only first party like meta, google, spring, etc are allowed. All other boilerplate must be written by developers, and on the rare occasion that a third party dependency is needed it's copied in source form, audited and re-hosted on our internal infrastructure with an internal name.
To justify it to business folks, we presented a simple math where I added the man-hours required to plug the vulnerabilities with the recurring cost of devsecops consultants and found that it's cheaper to reduce development velocity by 20-25%.
Also devsecops should never be offshored due to the scenario I presented in my second statement.
You've presented your argument as if rebutting mine, but to my mind you've reinforced my first paragraph:
* You are trusting large numbers of trustworthy developers.
* You have established a means of validating their trustworthiness: only trust reputable "first-party" code.
I think what you're doing is a pretty good system. However, there are ways to include work by devs who lack "first-party" bona-fides, such as when they participate in group development where their contributions are consistently audited. Do you exclude packages published by the ASF because some contributions may originate from troublesome jurisdictions?
In any case, it is not necessary to solve the traitorous author problem to address the attack vector right in front of us, which is compromised authors.
Problem is that beyond some threshold number of authors, the probability they're all trustworthy falls to zero.
It's true that smuggling multiple identities into the whitelist is one attack vector, and one reason why I said "cut down" rather than "eliminate". But that's not easy to do for most organizations.
For what it's worth, back when I was active at the ASF we used to vote on releases — you needed at least 3 positive votes from a whitelist of approved voters to publish a release outside the org and there was a cultural expectation of review. (Dunno if things have changed.) It would have been very difficult to duplicate this NPM attack against the upstream ASF release distribution system.
"Find large numbers of trustworthy dependency authors in your neighborhood!"
"Large numbers of trustworthy dependency authors in your town can't wait to show you their hottest code paths! Click here for educational livecoding sessions!"
I don't understand your critique.
Establishing a false identity well enough to fool a FOSS author or organization is a lot of work. Even crafting a spear phishing email/text campaign doesn't compare to the effort you'd have to put in to fool a developer well enough to get offered publishing privileges.
Of course it's possible, but so are beat-them-with-a-five-dollar-wrench attacks.
See auto update bots on Github. https://docs.github.com/en/code-security/dependabot/dependab... And since Github does it, it must be a good thing, right? Right???
Rather than adding friction there is something else that could benefit from having as little friction as sharing code: publishing audits/reviews.
Be that as it may, a system that can fail catastrophically will. Security shouldn't be left to choice.
> This is a culture issue with developers who find it OK to have hundreds of (transitive) dependencies, and then follow processes that, for all intents and purposes, blindly auto update them
I do not know about NPM. But in Rust this is common practice.
Very hard to avoid. The core of Rust is very thin, to get anything done typically involves dozens of crates, all pulled in at compile time from any old developer implicitly trusted.
The same is true for go and for java.
You can write entire applications in Go without resorting to any dependencies, the std lib is quite complete.
Most projects will have a healthy 5-20 dependencies though, with very little nested modules.
Unfortunately that's almost the whole industry. Every software project I've seen has an uncountable amount of dependencies. No matter if npm, cargo, go packages, whatever you name.
Every place I ever worked at made sure to curate the dependencies for their main projects. Heck, in some cases that was even necessary for certifications. Web dev might be a wild west, but as soon as your software is installed on prem by hundreds or thousands of paying customers the stakes change.
Curating dependencies won't prevent all supply chain attacks though
Zero-external-dependency Go apps are far more feasible than Rust or Node, simply because of the size and quality of the standard library.
Just the other day someone argued with me that it was reasonable for Limbo (the SQLite Rust rewrite) to have 3135 dependencies (of those, 1313 Rust dependencies).
https://github.com/tursodatabase/turso/network/dependencies
Even more wild considering that SQLite prides itself on having zero dependencies. Sounds like a doomed project.
This is incredible.
At this rate, there's a non-zero chance that one of the transitive dependencies is SQLite itself.
But it will be safe SQlite, called from Rust.
Yeah. You have dev dependencies in there, those alone will increase number of dependencies by ~500, without ending up in the final product.
Those numbers are way off their actual number.
Right. Allowing 500 strangers to push code to our CI infra, or developer laptops, with approximately zero review, sounds similarly ill advised.
That JLR got their factories hacked, rather than customer cars, is less bad for sure. But it's still pretty bad.
Also, before arguing that code generators should get a pass as they don't “end up in the final product”, you really should read “Reflections on trusting trust” by Ken Thompson.
> Right. Allowing 500 strangers to push code to our CI infra
That's bullshit, pure and simple. If you pull in a deeply nested dependency like icu_normalizer it has 30 dependencies, OMGHAXOZRS. I'm doing this, so I don't have to spend a day going through the library.
Except of the 30 depedencies crates, there are 10 from ICUX repository, and then you have almost standard dependencies like proc-macro/syn/quote crates from dtolnay, `zerofrom` from Google. `smallvec` from the Servo project, and yoke from... checks notes... from ICUX.
The only few remaining crates here are `write16`, `utf8_iter` and `utf16_iter` that are written from hsivonen, who is also a ICUX contributor.
So even for 30 dependencies, you actually depend on proc-macro/syn/quote which are foundational crates. Few crates from Google, few crates from Servo, and three crates written by another ICUX contributor.
We started with 30 dependencies and ended up with 3 strangers
500 dev dependencies doesn’t seem reasonable either…
Even 50 seems unreasonable...
There is another related growing problem in my recent observation. As a Debian Developer, when I try to audit upstream changes before pulling them in to Debian, I find a huge amount of noise from tooling, mostly pointless. This makes it very difficult to validate the actual changes being made.
For example, an upstream bumps a version of a lint tool and/or changes style across the board. Often these are labelled "chore". While I agree it's nice to have consistent style, in some projects it seems to be the majority of the changes between releases. Due to the difficulty in auditing this, I consider this part of the software supply chain problem and something to be discouraged. Unless there's actually reason to change code (eg. some genuine refactoring a human thinks is actually needed, a bug fix or new feature, a tool exposed a real bug, or at least some identifiable issue that might turn into a bug), it should be left alone.
I agree with this and it's something I've encountered when just trying to understand a codebase or track down a bug. There's a bit of the tail wagging the dog as an increasing proportion of commits are "meta-code" that is just tweaking config, formatting, etc. to align with external tools (like linters).
> Unless there's actually reason to change code (eg. some genuine refactoring a human thinks is actually needed, a bug fix or new feature, a tool exposed a real bug, or at least some identifiable issue that might turn into a bug), it should be left alone.
The corollary to this is "Unless there's actually a need for new features that a new version provides, your existing dependency should be left alone". In other words things should not be automatically updated. This is unfortunately the crazy path we've gone down, where when Package X decides to upgrade, everyone believes that "the right thing to do" is for all its dependencies to also update to use that and so on down the line. As this snowballs it becomes difficult for any individual projects to hold the line and try to maintain a slow-moving, stable version of anything.
I'm using difftastic, it cuts down a whole lot of the noise
https://difftastic.wilfred.me.uk/
This looks good! Unfortunately it looks like it also suffers from exactly the same software supply chain problem that we need to avoid in the first place: https://github.com/Wilfred/difftastic/blob/master/Cargo.lock
Edit: also, consider how much of https://github.com/Wilfred/difftastic/commits/master/ is just noise in itself. 15k commits for a project that appears to only be about four years old.
"exactly the same software supply chain problem"
While the crates ecosystem is certainly not immune to supply chain attacks this over generalization is not justified.
There are several features that make crates.io more robust than npm. One of them is that vulnerable versions can be yanked without human intervention. Desperate comments from maintainers like this one[1] from just a few days ago would not happen with crates.io.
There are also features not provided by crates.io that make the situation better. For example you could very easily clone the repo and run
to check how many of the packages had human audits. I'd done it if I was on a computer, but a quick glance at the Cargo.lock file makes me confident that you'd get a significant number.[1] https://news.ycombinator.com/item?id=45170687
The main issue there is that the maintainer lost access to their account. Yanking malicious packages is better, but even just being able to release new patch versions would've stopped the spread, but they were not able to do so for the packages that didn't have a co-publisher. How would crates.io help in this situation?
FWIW npm used to allow unpublishing packages, but AFAIK that feature was removed in the wake of the left-pad incident [1]. Altho now with all the frequent attacks, it might be worth considering if ecosystem disruption via malicious removal of pacakge would be lesser of two evils, compared to actual malware being distributed.

I'd argue it's more of a culture thing, not technical thing.
In both JavaScript and Rust, it's normal/encouraged to just add a tiny dependency to the package manager. The communities even pride themselves, that they have such good package managers to allow this.
It's this "yeah, there is a crate for this tiny function I need, let's just include it" mentality that makes the ecosystem vulnerable.
People need to be responsible for whatever they include, either pay the price by checking all versions up front, or pay it by risking shipping a vulnerable program that it's much harder to retract than a JavaScript frontend.
In Rust we have cargo vet, where we share these audits and use them in an automated fashion. Companies like Google and Mozilla contribute their audits.
I wish cargo went with crev instead, that has a much better model for distributed code audits.

How to backport security fixes to vetted packages?
It's too bad MS doesn't own npm, and/or GitHub repositories. Wait
Nuget, Powershell gallery, the marketplaces for VSCode/VS/AZDo and the Microsoft Store too. Probably another twenty.
They collect package managers like funko pops.
I'm not quite sure about the goal. Maybe some more C# dev kit style rug-pulls where the ecosystem is nominally open-source but MS own the development and distribution so nobody would bother to compete.
I took those acquisitions and a few others like LinkedIn and all the visual studio versions as a sign that Microsoft is trying to own the software engineer career as a domain.
And it's a great idea, similar thematically to certificate transparency
I'd like to think there are ways to do this and keep things decentralized.
Things like: Once a package has more than [threshold] daily downloads for an extended period of time, it requires 2FA re-auth/step-up on two separate human-controlled accounts to approve any further code updates.
Or something like: for these popular packages, only a select list of automated build systems with reproducible builds can push directly to NPM, which would mean that any malware injector would need to first compromise the source code repository. Which, to be fair, wouldn't necessarily have stopped this worm from propagating entirely, but would have slowed its progress considerably.
This isn't a "sacrifice all of NPM's DX and decentralization" question. This is "a marginally more manual DX only when you're at a scale where you should be release-managing anyways."
I think that we should impose webauthn 2fa on all npm accounts as the only acceptable auth method if you have e.g., more than 1 million total downloads.
Someone could pony up the cash to send out a few thousand yubikeys for this and we'd all be a lot safer.
Why even put a package download count on it? Just require it for everything submitted to NPM. It's not hard.
Because then it's extra hassle and expense for new developers to publish a package, and we're trying to keep things decentralized.
It's already centralized by virtue of using and relying on NPM as the registry.
If we want decentralized package management for node/javascript, you need to dump NPM - why not something like Go's system which is actually decentralized? There is no package repository/registry, it's all location based imports.
Decentralized? This is a centralized package registry. There is nothing decentralized about it.
oh right, good point, I wonder when somebody will just sue NPM for any damage caused. That's really the only way we'll see change I think.
I don’t understand what benefits this kind of “decentralization” offers
Larger pool of people you can hack/blackmail/coerce into giving you access to millions of systems :)
Download counters are completely useless. I could download your package 2 million times in under a minute and cause you to need the 2FA.
And true 2FA means you can't automate publishing from github's CI. Python is going the other direction. There is a fake 2FA that is just used to generate tokens and there is a preferential channel to upload to pypi via github's CI.
But in my opinion none of this helps with security. But it does help to de-anonymise the developers, which is probably what they really want to do, without caring if those developers get hacked and someone else uses their identity to do uploads.
Even the simplest "any maintainer can click a push notification on their phone to verify that they want to push an update to $package" would have stopped this worm in its tracks!
How would that work for CI release flows? I have my Rust crates, for example, set up to auto-publish whenever I push a tag to its repo.
Pypi did that, i got 2 google keys for free. But I used them literally once, to create a token that never expires and that is what I actually use to upload on pypi.
(I did a talk at minidebconf last year in toulouse about this).
If implemented like this, it's completely useless, since there is actually no 2fa at all.
Anyway the idea of making libre software developers work more is a bad idea. We do it for fun. If we have to do corporate stuff we want a corporate salary to go with.
PyPI already has this. It was a little bit annoying when they imposed stricter security on maintainers, but I can see the need.
> two separate human-controlled accounts to approve any further code updates.
Except most projects have 1 developer… Plus, if I develop some project for free I don't want to be wasting time and work for free for large rich companies. They can pay up for code reviews and similar things instead of adding burden to developers!
To be clear, Debian does not audit code like you might be suggesting they do. There are checks for licensing, source code being missing, build reproducibility, tests and other things. There is some static analysis with lintian, but not systematically at the source code level with tools like cppcheck or rust-analyzer or similar. Auditing the entirety of the code for security issues just isn't feasible for package maintainers. Malware might be noticed while looking for other issues, that isn't guaranteed though, the XZ backdoor wasn't picked up by Debian.
https://lintian.debian.org/
Distros are struggling with the amount of packages they have to maintain and update regularly. That's one of the main reasons why languages built their own ecosystems in the first place. It became popular with CPAN and Maven and took off with Ruby gems.
Linux distros can't even provide all the apps users want, that's why freshmeat existed and we have linuxbrew, flatpak, Ubuntu multiverse, PPA, third party Debian repositories, the openSUSE Buildservice, the AUR, ...
There is no community that has the capacity to audit and support multiple branches of libraries.
You can use debian's version of your npm packages if you'd like. The issues you're likely to run into are: some libraries won't be packaged period by debian; those that are might be on unacceptably old versions. You can work around these issues by vendoring dependencies that aren't in your distro's repo, ie copying a particular version into your own source control, manually keeping up with security updates. This is, to my knowledge, what large tech companies do. Other companies that don't are either taking a known risk with regards to vulnerabilities, or are ignorant. Ignorance is very common in this industry.
The lack of an easy method to automatically pull in and manage dependencies in C/C++ is starting to look a lot more like a feature than a bug now.
Author of Odin is also against adding a package manager: https://www.gingerbill.org/article/2025/09/08/package-manage...
But there's so much UB in C++ that can be exploited that I doubt attackers lament the lack of a module system to target. ;)
Right. Like NPM, Debian also supports post-install hooks for its packages. Not great (ask Michael Stapelberg)! But this is still a bit better than the NPM situation because at least the people writing the hooks aren't the people writing the applications, and there's some standards for what is considered sane to do with such hooks, and some communal auditing of those hooks' behavior.
Linux distros could still stand to improve here in a bunch of ways, and it seems that a well-designed package ecosystem truly doesn't need such hooks at the level of the package manager at all. But this kind of auditing is one of the useful functions of downstream software distros for sure.
I've been arguing a couple of times that the 2 main reasons people want package management in languages are
1. Using an operating system with no package management 2. Poor developer discipline, i.e. developers always trying to use the latest version of a package.
So now we have lots of poorly implemented language package managers, docker containers on top being used as another package management layer (even though that's not their primary purpose but many people use the like that) and the security implications of pulling in lots of random dependencies without any audit.
Developing towards a stable base like Debian would not be a pancea, but alliviate the problems by at least placing another audit layer in between.
It doesn't matter if the operating system I personally use has a good package manager, I need to release it in a form that all the people using it can work with. There are a lot of OSes out there, with many package managers.
Even if we make every project create packages in every package manager, it still wouldn't add any auditing.
Nope. It's because:
1. You don't want to tie your software to the OS. Most people want their software to be cross-platform. Much better to have a language-specific package manager because I'm using the same language on every OS. And when I say "OS" here, I really mean OS or Linux distro, because Linux doesn't have one package manager.
2. OS package managers (where they even exist), have too high a bar of entry. Not only do you have to make a load of different packages for different OSes and distros, but you have to convince all of them to accept them. Waaay too much work for all but the largest projects.
You're probably going to say "Good! It would solve this problem!", but I don't think the solution to package security is to just make it so annoying nobody bothers. We can do better than that.
I actually agree in the context of user software people often want the latest and that Windows and OS don't have proper package management is an issue.
However we are talking in the context of NPM packages which by the vast majority would be running inside a container on some server. So how could that software not use a stable Debian base for example.
And arguing that package management is to complicated is a bit ridiculous considering how many workloads are running in docker containers which I'd argue are significantly more complex
So, who is going to audit the thousands of new packages/versions that are published to npm every day? It only works for Debian because they hand-pick popular software.
Maybe NPM should hand pick popular packages and we should get away from this idea of every platform should always let everyone publish. Curation is expensive, but it may be worthwhile for mature platforms.
This is maybe where we could start getting into money into the opensource ecosystems.
One idea I've had is that publishing is open as today, but security firms could offer audit signatures.
So a company might pay security firms and only accept updates to packages that have been audited by by 1,2,3 or more of their paid services.
Thus money would be paid in the open to have eyes on changes for popular packages and avoid the problem of that weird lone maintainer in northern Finland being attacked by the Chinese state.
Errr, you! If you brought the dependency, it is now your job to maintain it and diff every update for backdoor.
> Keep a stable distro where new packages aren't added and versions change rarely (security updates and bugfixes only, no new functionality). This is what most people use.
Unfortunately most people don't want old software that doesn't support newer hardware so most people don't end up using Debian stable.
I don't know why you went with hardware.
Most people don't want old software because they don't want old software.
They want latest features, fixes and performance improvements.
It'd be interesting to see how much of the world runs on Debian containers, where most of the whole "it doesn't support my insert consumer hardware here" argument is completely moot.
Enable the Backport sources. The recent kernels there have supported all my modern personal devices.
What hardware isn't supported by Debian stable that is supported by unstable?
Or is this just a "don't use Linux" gripe?
I haven't had much problems prior but Blackwell support was really buggy for the first two weeks.
> Unfortunately most people don't want old software
"old" is a strange way to spell "new, unstable, and wormed".
I want old software. Very little new features are added to most things i care about, mostly it is just bloat, AI slop, and monthly subscription shakedowns being added to software today.
Yeah, after seeing all of the crazy stuff that has been occurring around supply chain attacks, and realizing that latest Debian stable (despite the memes) already has a lot of decent relatively up-to-date packages for Python, it's often easier to default to just building against what Debian provides.
Exactly, in a way Debian (or any other distro) is an extended standard library.
In practice, my experience is that this ends up with only old versions of things in the stable package repos. So many times I run into a bug, and then find out that the bug has been fixed in a newer version but it isn't updated in the stable repo. So now you end up pulling an update out of band, and you are in the same boat as before.
I don't know how you avoid this problem
You're overestimating the amount of auditing these distros do for the average package; in reality there is very little.
The reason these compromised packages typically don't make it in to e.g. Debian is because this all tends to be discovered quite quickly, before the package maintainer has a chance to update it.
> NPM, Python, Rust, Go, Ruby all suffer from this problem, because they have centralized and open package repositories
Can you point me to Go's centralized package repository?
https://pkg.go.dev/
Which works together with
https://proxy.golang.org/
That's a doc site and a pull-through cache, neither is a package repository
https://github.com/
git isn't centralized nor a package repository
For what it's worth, our code is on GitLab
Github is a centralized repository where the overwhelming majority of Go libraries are hosted.
So GitHub is every single programming language's centralized package repository?
Then what's the difference between git and npm, cargo, pypi, mvn et al?
For python I use Debian packages wherever possible. What I need is in there usually. I might even say almost always.
security updates and bugfixes only
Just wondering: while this is less of an attack surface, it's still a surface?
> The general solution is to do what Debian does.
If you ask these people, distributions are terrible and need to die.
Python even removed PGP signatures from Pypi because now attestation happens by microsoft signing your build on the github CI and uploading it directly to pypi with a never expiring token. And that's secure, as opposed to the developer uploading locally from their machine.
In theory it's secure because you see what's going in there on git, but in practice github actions are completely insecure so malware has been uploaded this way already.
Go’s package repository is just GitHub.
At the end of the day, it’s all a URL.
You’re asking for a blessed set of URLs. You’d have to convince someone to spend time maintaining that.
As hair splitting, that's actually not true: Go's package manager is just version control of which GitHub is currently the most popular hosting. And it also allows redirecting to your own version control via `go mod edit -replace` which leaves the sourcecode reference to GitHub intact, but will install it from wherever you like
How does that relate to the bigger conversation here? Are you suggesting people stop pulling Go packages from GitHub and only use local dependencies?
I wasn't trying to relate anything to the bigger conversation, I just meant to draw attention to the fact that GitHub is not golang's package manager
That said, I would guess the 'bigger conversation' is that it is much harder to tpyo <<import "github.com/DataaDog/datadog-api-client-go/v2/api/datadogV2">> than $(npm i dataadog) or similar in a "flat" package namespace (same for its $(uv pip install dataadog) friend)
None of those cited ones fix the dependency lineage issue, proving that release 1.1 was authored by the same chain of custody as release 1.0 of any given package. One can opt in to gpg verified dependencies in Maven, but it is opt-in. The .jar artifacts can also be cryptographically signed, but the risk that's trying to drive down is tamperproofing and not lineage, AFAIK
Golang at least gives you the option to easily vendor-ize packages to your local repository. Given what has happened here, maybe we should start doing this more!
This doesn't really help you. I assume Go records the sha1 hash of the commit it grabs, so it doesn't really matter if you vendor it, or download it every time.
The problem comes when you want to upgrade your dependencies. How do you know that they are trustworthy on first use?
Go uses the hash of the source code, not the commit ID. So there's no difference between vendoring and using the central repo.
npm has always downloaded to the current directory.
The problem with your idea is that you need to find the person who wants to do all this auditing of every version of Node/Python/Ruby libraries.
I believe good centralized infrastructure for this would be a good start. It could be "gamified" and reviewers could earn reputation for reviewing packages, common packages would be reviewed all the time.
Kinda like Stackoverflow for reviews, with optional identification and such.
And honestly an LLM can strap a "probably good" badge on things with cheap batch inference.
Decentralised auditing is what is needed.
https://github.com/crev-dev/
> suffer from this problem
Benefit from this feature.
I'm coming to the unfortunate realizattion that supply chain attacks like this are simply baked into the modern JavaScript ecosystem. Vendoring can mitigate your immediate exposure, but does not solve this problem.
These attacks may just be the final push I needed to take server rendering (without js) more seriously. The HTMX folks convinced me that I can get REALLY far without any JavaScript, and my apps will probably be faster and less janky anyway.
Traditional JS is actually among the safest environments ever created. Every day, billions of devices run untrusted JS code, and no other platform has seen sandboxed execution at such scale. And in nearly three decades, there have been very few incidents of large successful attacks on browser engines. That makes the JS engine derived from browsers the perfect tool to build a server side framework out of.
However, processes and practices around NodeJS and npm are in dire need of a security overhaul. leftpad is a cultural problem that needs to be addressed. To start with, snippets don't need to be on npm.
Sandboxing doesn't do any good if the malicious code and target data are in the same sandbox, which is the whole point of these supply-chain attacks.
I think the sandbox they're talking about is the browser, not the server (which runs node).
But if we think about a release publishing chain like a BSD process separation, why do they have to be?
Sure, there will be a step/stage that will require access to NPM publish credentials to publish to NPM. But why does this stage need to execute any code except a very small footprint of vetted code? It should just pickup a packaged, signed binary and move it to NPM.
The compilation/packaging step on the other hand doesn't need publishing rights to NPM. Ideally, it should only get a filesystem with the sources, dependencies and a few shared libraries and /sys or /proc dependencies it may need to function. Why does some dependency downloading need access to your entire filesystem? Maybe it needs some allowed secrets, but eh.
It's certainly a lot of change into existing pipelines and ideas, and it's certainly possible to poke holes into there if you want things to be easy. But it'd raise the bar quite a bit.
I mean, what does do good if your supply chain is attacked?
This said, less potential vendors supplying packages 'may' reduce exposure, but doesn't remove it.
Either way, not running the bleeding edge packages unless it's a known security fix seems like a good idea.
The supply chain infrastructure needs to stop being naive and allowing for insecure publishing.
- npm should require 2FA disallow tokens for publishing. This is an option, but it should be a requirement.
- npm should require using a trusted publisher and provenance for package with over 100k downloads a week and their dependencies.
- Github should require a 2FA step for automated publishing
- npm should add a cool down period where if won't install brand new packages without a flag
- npm should stop running postinstall scripts.
- npm should have an option to not install packages without provenance.
The reality is that for a huge crowd of developers 2FA doesn't do shit.
Javascript doesn't have a standard library, until it does the 170 million[1] weekly downloads of packages like UUID will continue. You can't expect people to re-write everything over and over.
[1]https://www.npmjs.com/package/uuid
That's not the problem. There is a cultural (and partly technical) aversion in JavaScript to large libraries - this is where the issue comes from. So, instead of having something like org.apache.commons in Java or Boost in C++ or Posix in C, larger libraries that curate a bunch of utilities missing from the standard library, you get an uncountable number of small standalone libraries.
I would bet that you'll find a third party `leftpad` implementation in org.apache.commons or in Spring or in some other collection of utils in Java. The difference isn't the need for 3rd party software to fix gaps in the standard library - it's the preference for hundreds of small dependencies instead of one or two larger ones.
Lodash is a good counterpoint, but it’s falling out of style since the JS runtimes support more basic things now.
JS apps, despite the HN narrative, have a much stronger incentive to reduce bundle/“executable” size compared to most other software, because the expectation is for your web app to “download” nearly instantly for every new user. (Compare to nearly any other type of software, client or server, where that’s not an expectation.)
JS comes with exactly zero tools out of the box to make that happen. You have to go out of your way to find a modern toolchain that will properly strip out dead code and create optimized scripts that are as small as possible.
This means the “massive JS library which includes everything” also depends on having a strong toolchain for compiling code. And while may professional web projects have that, the basic script tag approach is still the default and easiest way to get started… and pulling in a massive std library through that is just a bad idea.
This baseline — the web just simply having different requirements around runtime execution — is part of where the culture comes from.
And because the web browser traditionally didn’t include enough of a standard library for making apps, there’s a strong culture of making libraries and frameworks to solve that. Compare to native apps, where there’s always an official sdk or similar for building apps, and libraries like boost are more about specific “lower level” language features (algorithms, concurrency, data structures, etc) and less about building different types of software like full-blown interactive applications and backend services.
There are attempts to solve this (Deno is probably the best example), but buy-in at a professional level requires a huge commitment to migrate and change things, so there’s a lot of momentum working against projects like that.
1000% agree. Javascript is weak in this regard if you compare it to major programming languages. It just adds unnecessary security risks not having a language with built in imports for common things like making API calls out or parsing JSON, for example.
It does have functions for that, “fetch” and “JSON.parse,” available in most JS runtimes.
FYI, there's crypto.randomUUID()
That's built in to server side and browser.
You have the DOM and Node APIs. Which I think cover more than C library or Common Lisp library. Adding direct dependencies is done by every project. The issue is the sprawling deps tree of NPM and JS culture.
> You can't expect people to re-write everything over and over.
That’s the excuse everyone is giving, then you see thousands of terminal libraries and calendar pickers.
When I was learning JS/node/npm as a total programming newbie, a lot of the advice online was basically “if you write your own version of foobar when foobar is already available as an npm package, you’re stupid for wasting your time”.
I’d never worked in any other ecosystem, and I wish I realized that advice was specific to JS culture
It's not really bad advice, it just has different implications in Javascript.
In other languages, you'd have a few dependencies on larger libraries providing related functionality, where the Javascript culture is to use a bunch of tiny libraries to give the same functionality.
Sometimes I wonder how many of these tiny libraries are just the result of an attempt to have something ready for a conference talk and no one had the courage to say "Uh, Chris, that already exists, and the world doesn't need your different approach on it."
> You can't expect people to re-write everything over and over.
Call me crazy but I think agentic coding tools may soon make it practical for people to not be bogged down by the tedium of implementing the same basic crap over and over again, without having to resort to third party dependencies.
I have a little pavucontrol replacement I'm walking Claude Code through. It wanted to use pulsectl but, to see what it could do, I told it no. Write your own bindings to libpulse instead. A few minutes later it had that working. It can definitely write crap like leftpad.
I think the smallest C library I’ve seen was a single file to include on your project if you want terminal control like curses on windows. A lot of libraries on npm (and cargo) should be gist or a blog post.
15+ years ago used to copy paste utility functions from stackoverflow, now people npm installing packages for a function or two.
It shouldn't matter how many libraries npm supports.
None of those security guarantees matter when you take out the sandbox, which is exactly what server-side JS does.
The isolated context is gone and a single instance of code talking to an individual client has access to your entire database. It’s a completely different threat model.
So maybe the solution would be to sandbox Node.js?
I'm not quite sure what that would mean, but if it solves the problem for browsers, why not for server?
You can't sandbox the code that is supposed to talk to your DB from your DB.
And even on client side, the sandboxing helps isolate any malicious webpage, even ones that are accidentally malicious, from other webpages and from the rest of your machine.
If malicious actors could get gmail.com to run their malicious JS on the client side through this type of supply-chain attack, they could very very easily steal all of your emails. The browser sandbox doesn't offer any protection from 1st party javascript.
Deno does exactly that.
But in practice, to do useful things server-side you generally need quite a few permissions.
> Traditional JS is actually among the safest environments ever created.
> However, processes and practices around NodeJS and npm are in dire need of a security overhaul. leftpad is a cultural problem that needs to be addressed. To start with, snippets don't need to be on npm.
Traditional JS is the reason we have all of these problems around NodeJS and npm. It's a lot better than it was, but a lot of JS tooling came up in the time when ES5 and older were the standard, and to call those versions of the language lacking is... charitable. There were tons of things that you simply couldn't count on the language or its standard library to do right, so a culture of hacks and bandaids grew up around it. Browser disparities didn't help either.
Then people said, "Well, why don't we all share these hacks and bandaids so that we don't have to constantly reinvent the wheel?", and that's sort of how npm got its start. And of course, it was the freewheeling days of the late 00s/early 10s, when you were supposed to "move fast and break things" as a developer, so you didn't have time to really check if any of this was secure or made any sense. The business side wanted the feature and they wanted it now.
The ultimate solution would be to stop slapping bandaids and hacks on the JS ecosystem by making a better language but no one's got the resolve to do that.
Python is the other extreme, with an incredibly heavy weight standard library with a built in function to do just about anything.
E.g. there is a built in function that takes elements pairwise from a list! That level of minutia being included feels nuts having come from other languages.
Interestingly AI should be able to help a lot with desire to load those snippets.
What I'm wondering if it would help the ecosystem, if you were able to rather load raw snippets into your codebase, and source control as opposed to having them as dependencies.
So e.g. shadcn component pasting approach.
For things like leftPad, cli colors and others you would just load raw typescript code from a source, and there you would immediately notice something malicious or during code reviews.
You would leave actual npm packages to only actual frameworks / larger packages where this doesn't make sense and expect higher scrutiny, multi approvals of releases there.
> I'm coming to the unfortunate realizattion that supply chain attacks like this are simply baked into the modern JavaScript ecosystem.
I see this odd take a lot - the automatic narrowing of the scope of an attack to the single ecosystem it occurred in most recently, without any real technical argument for doing so.
What's especially concerning is I see this take in the security industry: mitigations put in place to target e.g. NPM, but are then completely absent for PyPi or Crates. It's bizarre not only because it leaves those ecosystems wide open, but also because the mitigation measures would be very similar (so it would be a minimal amount of additional effort for a large benefit).
Could you say more about what mitigations you’re thinking of?
I ask because think the directionality is backwards here: I’ve been involved in packaging ecosystem security for the last few years, and I’m generally of the opinion that PyPI has been ahead of the curve on implementing mitigations. Specifically, I think widespread trusted publishing adoption would have made this attack less effective since there would be fewer credentials to steal, but npm only implemented trusted publishing recently[1]. Crates also implemented exactly this kind of self-scoping, self-expiring credential exchange ahead of npm.
(This isn’t to malign any ecosystem; I think people are also overcorrect in treating this like a uniquely JavaScript-shaped problem.)
[1]: https://github.blog/changelog/2025-07-31-npm-trusted-publish...
> PyPI has been ahead of the curve on implementing mitigations
Indeed, crates.io implemented PyPI's trusted publishing and explicitly called out PyPI as their inspiration: https://blog.rust-lang.org/2025/07/11/crates-io-development-...
I agree other repos deserve a good look for potential mitigations as well (PyPI too, has a history of publishing malicious packages).
But don't brush off "special status" of NPM here. It is unique in that JS being language of both front-end and back-end, it is much easier for the crooks to sneak in malware that will end up running in visitor's browser and affect them directly. And that makes it a uniquely more attractive target.
npm in itself isn't special at all, maybe the userbase is but that's irrelevant because the mitigation is pretty easy and 99.9999% effective, works for every package manager and boils down to:
1- thoroughly and fully analyze any dependency tree you plan to include 2- immediately freeze all its versions 3- never update without very good reason or without repeating 1 and 2
in other words: simply be professional, face logical consequences if you aren't. if you think one package manager is "safer" than others because magic reasons odds are you'll find out the hard way sooner or later.
Your item #1 there may be simple, but that's not the same as being easy.
agreed, bad wording. it so happens though that sw development includes many problems and practices that aren't easy and are still part of the job.
Good luck with nr 1 in the js ecosystem and its 30k dependencies 50 branches deep per package
As an outsider looking in as I don't deal with NPM on a daily basis, the 30k dependencies going 50 branches deep seems to be the real problem here. Code reuse is an admiral goal but this seems absurd. I have no idea if these numbers are correct or exaggerations but from my limited time working with NPM a year or two ago it seems like it's a definite problem.
I'm in the C ecosystem mostly. Is one NPM package the equivalent of one object file? Can NPM packages call internal functions for their dependencies instead of relying so heavily on bringing in so many external ones? I guess it's a problem either way, internal dependencies having bugs vs supply chain attacks like these. Doesn't bringing in so many dependencies lead to a lot of dead code and much larger codebases then necessary?
> Is one NPM package the equivalent of one object file?
No. The closest thing to a package (on almost every language) is an entire library.
> Can NPM packages call internal functions for their dependencies instead of relying so heavily on bringing in so many external ones?
Yes, they can. They just don't do it.
> Doesn't bringing in so many dependencies lead to a lot of dead code and much larger codebases then necessary?
There aren't many unecessary dependencies, because the number of direct dependencies on each package is reasonable (on the order of 10). And you don't get a lot of unecessary code because the point of tiny libraries is to only import what you need.
Dead code is not the problem, instead the JS mentality evolved that way to minimize dead code. The problem is that dead code is actually not that much of an issue, but dependency management is.
there are indeed monster packages but you should ask yourself if you need them at all, because if you really do there is no way around performing nr1. you get the code, you own it. you propagate malware by negligence, you're finished as a sw engineer. simple as that.
personally i keep dependencies at a minimum and are very picky with them, partly because of nr1, but as a general principle. of course if people happily suck in entire trees without supervision just to print ansi colors on the terminal or, as in this case, use fancy aliases for colors then bad things are bound to happen. (tbf tinycolor has one single devDependency, shim-deno-test, which only requires typescript. that should be manageable)
i'll grant you that the js ecosystem is special, partly because the business has traditionally reinforced the notion of it being accessory, superficial and not "serious" development. well, that's just naivety, it is as critical a component as any other. ideally you should even have a security department vetting the dependencies for you.
Which mitigations specifically are in npm but not in crates.io?
As far as I know crates.io has everything that npm has, plus
- strictly immutable versions[1]
- fully automated and no human in the loop perpetual yanking
- no deletions ever
- a public and append only index
Go modules go even further and add automatic checksum verification per default and a cryptographic transparency log.
Contrast this with docker hub for example, where not even npm's basic properties hold.
So, it is more like
docker hub ⊂ npm ⊂ crates.io ⊂ Go modules
[1] Nowadays npm has this arguably too
> Go modules go even further and add automatic checksum verification per default
Cargo lockfiles contain checksums and Cargo has used these for automatic verification since time immemorial, well before Go implemented their current packaging system. In addition, Go doesn't enforce the use of go.sum files, it's just an optional recommendation: https://go.dev/wiki/Modules#should-i-commit-my-gosum-file-as... I'm not aware of any mechanism which would place Go's packaging system at the forefront of mitigation implementations as suggested here.
To clarify (a lot of sibling commenters misinterpreted this too so probably my fault - can't edit my comment now):
I'm not referring to mitigations in public repositories (which you're right, are varied, but that's a separate topic). I'm purely referring to internal mitigations in companies leveraging open-source dependencies in their software products.
These come in many forms, everything from developer education initiatives to hiring commercial SCA vendors, & many other things in between like custom CI automations. Ultimately, while many of these measures are done broadly for all ecosystems when targeting general dependency vulnerabilities (CVEs from accidental bugs), all of the supply-chain-attack motivated initiatives I've seen companies engage in are single-ecosystem. Which seems wasteful.
Most people have addressed the package registry side of NPM.
But NPM has a much, much bigger problem on the client side, that makes many of these mitigations almost moot. And that is that `npm install` will upgrade every single package you depend on to its latest version that matches your declared dependency, and in JS land almost everyone uses lax dependency declarations.
So, an attacker who simply publishes a new patch version of a package they have gained access to will likely poison a good chunk of all of the users of that package in a relatively short amount of time. Even if the projects using this are careful and use `npm ci` instead of `npm install` for their CI builds, it will still easily get developers to download and run the malicious new version.
Most other ecosystems don't have this unsafe-by-default behavior, so deploying a new malicious version of a previously safe package is not such a major risk as it is in NPM.
> in JS land almost everyone uses lax dependency declarations
They do, BUT.
Dependency versioning schemes are much more strictly adhered to within JS land than in other ecosystems. PyPi is a mishmash of PEP 440, SemVer, some packages incorrectly using one in the format of the other, & none of the 3 necessarily adhering to the standard they've chosen. Other ecosystems are even worse.
Also - some ecosystems (PyPi again) are committing far worse offences than lax versioning - versionless dependency declaration. Heavy reliance on requirements.txt without lockfiles where half the time version isn't even specified at all. Astral/Poetry are improving the situation here but things are still bad.
Maven land is full of plugins with automated pom.xml version templating that has effectively the same effect as lax versioning, but without any strict adherence to any kind of standard like semver.
Yes, the situation in JS land isn't great, but there are much worse offenders out there.
The point is still different. In PyPI, if I put `requests` in my requirements.txt, and I run `pip install -r requirements.txt` every time I do `make build`, I will still only get one version of requests - the latest available the first time I installed it. This severely reduces the attack radius compared to NPM's default, where I would get the latest (patch) version of my dependency every day. And the ecosystem being committed to respecting semver is entirely irrelevant to supply chain security. Malicious actors don't care about semver.
Overall, publishing a new malicious version of a package is a much lesser problem in virtually any ecosystem other than NPM; in NPM, it's almost an automatic remote code execution vulnerability for every NPM dev, and a persistent threat for many NPM packages even without this.
Generally you have the right of it, but a word of caution for Pythonistas:
> The point is still different. In PyPI, if I put `requests` in my requirements.txt, and I run `pip install -r requirements.txt` every time I do `make build`, I will still only get one version of requests - the latest available the first time I installed it.
Only because your `make build` is a custom process that doesn't use build isolation and relies on manually invoking pip in an existing environment.
Ecosystem standard build tools (including pip itself, using `pip wheel` — which really isn't meant for distribution, but some people seem to use it anyway) default to setting up a new virtual environment to build your code (and also for each transitive dependency that requires building — to make sure that your dependencies' build tools aren't mutually incompatible, or broken by other things in the envrionment). They will read `requests` from `[project.dependencies]` in your pyproject.toml file and dump the latest version in that new environment, unless you use tool-specific configuration (or of course a better specification in pyproject.toml) to prevent that. And if your dependencies were only available as sdists, the build tool would even automatically, recursively attempt to build those, potentially running arbitrary code from the package in the process.
> This severely reduces the attack radius compared to NPM's default, where I would get the latest (patch) version of my dependency every day.
By default npm will create a lock file and give you the exact same version every time unless you manually initiate an upgrade. Additionally you could even remove the package-lock.json and do a new npm install and it still wouldn't upgrade the package if it already exists in your node_modules directory.
Only time this would be true is if you manually bump the version to something that is incompatible, or remove both the package-lock.json and your node_modules folder.
Ahh this might explain the behavior I observed when running npm install from a freshly checked out project where it basically ignored the lock file. If I recall in that situation the solution was to run an npm clean install or npm ci and then it would use the lock file.
> every time I do `make build`
I'm going to assume this is you running this locally to generate releases, presumably for personal projects?
If you're building your projects in CI you're not pulling in the same version without a lockfile in place.
> Maven land is full of plugins with automated pom.xml version templating that has effectively the same effect as lax versioning, but without any strict adherence to any kind of standard like semver.
Please elaborate on this. I'm a long-time Java developer and have never once seen something akin to what you're describing here. Maven has support for version ranges but in practice it's very rarely used. I can expect a project to build with the exact same dependencies resolved today and in six months or a year from now.
I'm not a Java (nor Kotlin) developer - I've only done a little Java project maintenance & even less Kotlin - I've mainly come at this as a tooling developer for dependency management & vulnerability remediation. But I have seen a LOT of varied maven-managed repos in that line of work (100s) and the approaches are wide - varied.
I know this is possible with custom plugins but I've mainly just seen it using maven wrapper & user properties.
There are things that are potentially possible such as templating pom.xml build files or adjusting dependencies based on user properties (this that what you're suggesting?), but what you're describing is definitely not normal, or best practice in the ecosystem and shouldn't be presented as if it's normal practice.
Attackers don't need these practices to be normal, they just need them to be common enough (significant minority of)
You're talking about things that aren't in the significant minority here.
`npm install` uses a lockfile by default and will not change versions. No, not transitives either. You would have to either manually change `package.json` or call `npm update`.
You'd have to go out of your way to make your project as bad as you're describing.
No, this is just wrong. It might indeed use package-lock.json if it matches your node_modules (so that running `npm install` multiple times won't download new versions). But if you're cloning a repo off of GitHub and running npm install for the first time (which a CI setup might do), it will take the latest deps from package.json and update the package-lock.json - at least this is what I've found many responses online claim. The docs for `npm ci` also suggest that it behaves differently from `npm install` in this exact respect:
> In short, the main differences between using npm install and npm ci are:
> The project must have an existing package-lock.json or npm-shrinkwrap.json.
> If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock.
Well but the docs you cited don't match what you stated. You can delete node_modules and reinstall, it will never update the package-lock.json, you will always end up with the exact same versions as before. The package-lock updating happens when you change version numbers in the package.json file, but that is very much expected! So no, running npm install will not pull in new versions randomly.
The internet disagrees. NPM will gladly ignore and update lock files. There may exist a way to actually respect lock files, but the default mode of operation does not work as you would naively expect.

Those stackoverflow posts are ancient and many major npm releases old, so in other words: irrelevant. That blog post is somewhat up to date but also very vague about the circumstances which would update the lockfile. Which certainly isn't that npm install updates dependencies to newer versions within the semver range, because it absolutely does not.
That's not true. Ci will never take new versions from your lock file.
A lot of people use tools like Dependabot which automates updates to the lockfile.
I mostly agree. But NPM is special, in that the exposure is so much higher. The hypothetical python+htmx web app might have 10s of dependencies (including transitive) whereas your typical Javascript/React will have 1000s. All an attacker needs to do is find one of many packages like TinyColor or Leftpad or whatever and now loads of projects are compromised.
Stuff like Babel, React, Svelte, Axios, Redux, Jest… should be self contained and not depend on anything other than being a peer dependency. They are core technological choices that happens early in the project and is hard or impossible to replace afterwards.
- I feel that you are unlikely to need Babel in 2025, most things it historically transpiled are Baseline Widely Available now (and most of the things it polyfilled weren't actually Babel's but brought in from other dependencies like core-js, which you probably don't need either in 2025). For the rest of the things it still transpiles (pretty much just JSX) there are cheaper/faster transpilers with fewer external dependencies and runtime dependencies (Typescript, esbuild). It should not be hard to replace Babel in your stack: if you've got a complex webpack solution (say from CRA reasons) consider esbuild or similar.
- Axios and Jest have "native" options now (fetch and node --test). fetch is especially nice because it is the same API in the browser and in Node (and Deno and Bun).
- Redux is self-contained.
- React itself is sort of self-contained, it's the massive ecosystem that makes React the most appealing that starts to drive dependency bloat. I can't speak to Svelte.
Last i checked react's new compiler still depends on babel! :(
> NPM is special, in that the exposure is so much higher.
NPM is special in the same way as Windows is special when it comes to malware: it's a more lucrative target.
However, the issue here is that - unlike Windows - targetting NPM alone does not incur significantly less overhead than targetting software registries more broadly. The trade-off between focusing purely on NPM & covering a lot of popular languages isn't high, & imo isn't a worthwhile trade-off.
Well, your typical Rust project has over 1000 dependencies, too. Zed has over 2000 in release mode.
Not saying this in defence of Rust or Cargo, but often times those dependencies are just different versions of the same thing. In a project at one of my previous companies, a colleague noticed we had LOADS of `regex` crate versions. Forgot the number but it was well over 100
That doesn't make sense. The most it could be is 3: regex 0.1.x, regex 0.2.y and regex 1.a.b. You can't have more because Cargo unifies on semver compatible versions and regex only has 3 semver incompatible releases. Plus, regex 1.0 has been out for eons. Pretty much everyone has moved off of 0.1 and 0.2.
That seems like a failure in workspace management. The most duplicates I've seen was 3, with crates like url or uuid, even in projects with 1000+ distinct deps.
Your typical Rust project does not have over 1000 dependencies.
Zed is not a typical Rust project; it's a full fledged editor that includes a significant array of features and its own homegrown UI framework.
> Zed is not a typical Rust project; it's a full fledged editor
Funny that text editor is being presented here as some kind of behemoth, not representative of typical software written in Rust. I guess typical would be 1234th JSON serialization library.
What is a "typical Rust project", I wonder?
One famous example is ripgrep (https://github.com/BurntSushi/ripgrep). Its Cargo.lock (which contains all direct and indirect dependencies) lists 65 dependencies (it has 66 entries, but one of them is for itself).
Also, that lock file includes development dependencies and dependencies for opt-in features like PCRE2. A normal `cargo build` will use quite a bit fewer than 65 dependencies.
I would actually say ripgrep is not especially typical here. I put a lot of energy into keeping my dependency tree slim. Many Rust applications have hundreds of dependencies.
We aren't quite at thousands of dependencies yet though.
Most of the biggest repositories already cooperate through the OpenSSF[0]. Last time I was involved in it, there were representatives from npm, PyPI, Maven Central, Crates and RubyGems. There's also been funding through OpenSSF's Alpha-Omega program for a bunch of work across multiple ecosystems[1], including repos.

The Rust folks are in denial about this
Until you go get malware
Supply chain attacks happen at every layer where there is package management or a vector onto the machine or into the code.
What NPM should do if they really give a shit is start requiring 2FA to publish. Require a scan prior to publish. Sign the package with hard keys and signature. Verify all packages installed match signatures. Semver matching isn’t enough. CRC checks aren’t enough. This has to be baked into packages and package management.
> Until you go get malware
While technically true, I have yet to see Go projects importing thousands of dependencies. They may certainly exist, but are absolutely not the rule. JS projects, however...
We have to realize, that while supply chain attacks can happen everywhere, the best mitigations are development culture and solid standard library - looking at you, cargo.
I am a JS developer by trade and I think that this ecosystem is doomed. I absolutely avoid even installing node on my private machine.
Here's an example off the top of my mind:
https://github.com/go-gitea/gitea/blob/main/go.sum
I think you are reading that wrong, go.sum isn't a list of dependencies it's a list of checksums for modules that were, at some point, used by this module. All those different versions of the same module listed there, they aren't all dependencies, at most one of them is.
Assuming 'go mod tidy' is periodically run go.mod should contain all dependencies (which in this case seems to be shy of 300, still a lot).
Half of go.sum dependencies generally are multiple versions of same package. 400 still a lot, but a huge project like gitea might need them I guess.
> cat go.sum |awk '{print $1}' | sort |uniq |wc -l
431
> wc -l go.sum
1156 go.sum
Sign the package with hard keys and signature.
That's really the core issue. Developer-signed packages (npm's current attack model is "Eve doing a man-in-the-middle attack between npm and you," which is not exactly the most common threat here) and a transparent key registry should be minimal kit for any package manager, even though all, or at least practically all, the ecosystems are bereft of that. Hardening API surfaces with additional MFA isn't enough; you have to divorce "API authentication" from "cryptographic authentication" so that compromising one doesn't affect the other.
How are users supposed to build and maintain a trust store?
In a hypothetical scenario where npm supports signed packages, let's say the user is in the middle of installing the latest signed left-pad. Suddenly, npm prints a warning that says the identity used to sign the package is not in the user's local database of trusted identities.
What exactly is the user supposed to do in response to this warning?
This is a solved problem. https://en.wikipedia.org/wiki/Web_of_trust
> What NPM should do if they really give a shit is start requiring 2FA to publish.
How does 2FA prevent malware? Anyone can get a phone number to receive a text or add an authenticator to their phone.
I would argue a subscrption model for 1 EUR/month would be better. The money received could pay for certification of packages and the credit card on file can leverage the security of the payments system.
How will multi-factor-authentication prevent such a supply chain issue?
That is, if some attacker create some dummy trivial but convenient package and 2 years latter half the package hub depends on it somehow, the attacker will just use its legit credential to pown everyone and its dog. This is not even about stilling credentials. It’s a cultural issue with bare blind trust to use blank check without even any expiry date.
https://en.wikipedia.org/wiki/Trust,_but_verify
That's an entirely different issue compared to what we're seeing here. If an attacker rug-pulls of course there is nothing that can be done about that other than security scanning. Arguably some kind of package security scanning is a core-service that a lot of organisations would not think twice about paying npm for.
> If an attacker rug-pulls of course there is nothing that can be done about that other than security scanning.
As another subthread mentioned (https://news.ycombinator.com/item?id=45261303), there is something which can be done: auditing of new packages or versions, by a third party, before they're used. Even doing a simple diff between the previous version and the current version before running anything within the package would already help.
If NPM really cared, they'd stop recommending people use their poorly designed version control system that relies on late-fetching third-party components required by the build step, and they'd advise people to pick a reliable and robust VCS like Git for tracking/storing/retrieving source code objects and stick to that. This will never happen.
NPM has also been sending out nag emails for the last 2+ years about 2FA. If anything, that constituted an assist in the attack on the Junon account that we saw a couple weeks ago.
NPM lock files seem to include hashes for integrity checking, so as long as you check the lock file into the VCS, what's the difference?
Wrong question; NPM isn't bedrock. The question to be answered if there is no difference is, "In that case, why bother with NPM?"
NPM does require 2FA to publish. I would love a workaround! Isn't it funny that even here on HN, misinformation is constantly being spread?
NPM does not require two-factor authentication. If two-factor authentication is enabled for your account and you wish to disable it, this explains how to do that if allowed by your organization:
<https://docs.npmjs.com/configuring-two-factor-authentication...>
It doesn't require 2FA in general, but it does for people with publish rights for popular packages, which covers most or all of the recent security incidents.
https://github.blog/changelog/2022-11-01-high-impact-package...
npm offers 2FA but it doesn't really advertise that it has a phishing-resistant 2FA (security keys, aka passkeys, aka WebAuthn) available and just happily lets you go ahead and use a very phishable OTP if you want. I place much of the blame for publishers getting phished on npm.
> The malware includes a self-propagation mechanism through the NpmModule.updatePackage function. This function queries the NPM registry API to fetch up to 20 packages owned by the maintainer, then force-publishes patches to these packages.
This is going to become an issue for a lot of managers, not just npm. Npm is clearly a very viable target right now, though. They're going to get more and more sophisticated.
Is the difference between the number of dev dependencies for eg. VueJs (a JavaScript library for marshalling Json Ajax responses into UI) and Htmx (a JavaScript library for marshalling html Ajax responses into UI) meaningful?
There is a difference, but it's not an order of magnitude and neither is a true island.
Granted, deciding not to use JS on the server is reasonable in the context of this article, but for the client htmx is as much a js lib with (dev) dependencies as any other.
https://github.com/bigskysoftware/htmx/blob/master/package.j...
https://github.com/vuejs/core/blob/main/package.json
Except that htmx's recommended usage is as a single <script> injected directly into your HTML page, not as an npm dependency. So unless you are an htmx contributor you are not going to be installing the dev dependencies.
AFAICT, the only thing this attack relies on, is the lack of scrutiny by developers when adding new dependencies.
Unless this lack of scrutiny is exclusive to JavaScript ecosystem, then this attack could just as well have happened in Rust or Golang.
I don't know Go, but Rust absolutely has the same problem, yes. So does Python. NPM is being discussed here, because it is the topic of the article, but the issue is the ease with which you can pull in unvetted dependencies.
Languages without package managers have a lot more friction to pull in dependencies. You usually rely on the operating system and its package-manager-humans to provide your dependencies; or on primitive OSes like Windows or macOS, you package the dependencies with your application, which involves integrating them into your build and distribution systems. Both of those involve a lot of manual, human effort, which reduces the total number of dependencies (attack points), and makes supply-chain issues like this more likely to be noticed.
The language package managers make it trivial to pull in dozens or hundreds of dependencies, straight from some random source code repository. Your dependencies can add their own dependencies, without you ever knowing. When you have dozens or hundreds of unvetted dependencies, it becomes trivial for an attacker to inject code they control into just one of those dependencies, and then it's game over for every project that includes that one dependency anywhere in their chain.
It's not impossible to do that in the OS-provided or self-managed dependency scenario, but it's much more difficult and will have a much narrower impact.
If you try installing npm itself on debian, you would think you are downloading some desktop environment. So many little packages.
At least in the JS world there are more people (often also more inexperienced people) who will add a dependency willy-nilly. This is due to many people starting out with JS these days.
That, and the ability to push an update without human interaction.
JavaScript does have some pretty insane dependency trees. Most other languages don’t have anywhere near that level of nestedness.
Don't they?
I just went to crates.io and picked a random newly updated crate, which happened to be pixelfix, which fixes transparent pixels in pngs.
It has six dependencies and hundreds of transient dependencies, may of which appear to be small and highly specific a la left-pad.
https://crates.io/crates/pixelfix/0.1.1/dependencies
Maybe this package isn't representative, but it feels pretty identical to the JS ecosystem.
It depends on `image` which in turn depends on a number of crates to handle different file types. If you disable all `image` features, it only has like 5 dependencies left.
And all those 5 remaining dependencies have lots of dependencies of their own. What's your point?
> What's your point?
Just defending Rust.
> 5 remaining dependencies have lots of dependencies of their own.
Mostly well-known crates like rayon, crossbeam, tracing, etc.
You cannot defend Rust if this is reality.
Any Rust project I have ever compiled pulled in over 1000 dependencies. Recently it was Zed with its >2000 dependencies.
I think it's justified for Zed. It does a lot of things.
Zed isn’t special, I doubt Sublime Text has thousands of dependencies. It’s a language/culture problem.
Edit: Ghostty is a good counter-example that is open source. https://github.com/ghostty-org/ghostty/tree/main/pkg
Zed is closer to IntelliJ or VSCode than to Sublime Text.
In the amount of bloat, yes.
It's not possible for a language to have an insane dependency tree. That's an attribute of a codebase.
Modern programming languages don't exist in a vacuum, they are tied to the existing codebase and libraries.
Sort of, but I don't really buy this argument. Someone could go and write the "missing JS stdlib" library that has no dependencies of its own. They could adopt release policies that reduce the risk of successful supply chain attacks. Other people could depend on it and not suffer deep dependency trees.
JS library authors in general could decide to write their own (or carefully copy-paste from libraries) utility functions for things rather than depend on a huge mess of packages. This isn't always a great path; obviously reinventing the wheel can come with its own problems.
So yes, I'd agree that the ecosystem encourages JS/TS developers to make use of the existing set of libraries and packages with deep dependency trees, but no one is holding a gun to anyone's head. There are other ways to do it.
Whatever you're trying to say, you aren't.
Maybe the language should have a standard library then.
C library is smaller than Node.js (you won’t have HTTP). What C have is much more respectable libraries. If you add libcurl or freetype to your project, it won’t pull the whole jungle with them.
What C doesn't have is an agreed-upon standard package manager. Which means that any dependency - including transitive ones! - requires some effort on behalf of the developer to add to the build. And that, in turn, puts pressure on library authors to avoid dependencies other than a few well-established libraries (like libpng or GLib),
You can add curl to a Rust project too.
But why, when reqwest is enough for 99% of cases.
It's bloated.
This makes little sense. Any popular language with a lax package management culture will have the exact same issue, this has nothing to do with JS itself. I'm actually doing JS quasi exclusively these days, but with a completely different tool chain, and feel totally unconcerned by any of these bi-weekly NPM scandals.
Rust is working on that. It's not far behind right now, leave it a couple of years.
They are. Any language that depends heavily on package managers and lacks a standard lib is vulnerable to this.
At some point people need to realize and go back to writing vanilla js, which will be very hard.
The rust ecosystem is also the same. Too much dependence on packages.
An example of doing it right is golang.
The solution is not to go back to vanilla JS, it's for people to form a foundation and build a more complete utilities library for JS that doesn't have 1000 different dependencies, and can be trusted. Something like Boost for C++, or Apache Commons for Java.
> Something like Boost for C++, or Apache Commons for Java.
Honestly I wish Python worked this way too. The reason people use Requests so much is because urllib is so painful. Changes to a first-party standard library have to be very conservative, which ends up leaving stuff in place that nobody wants to use any more because they have higher standards now. It'd be better to keep the standard library to a minimum needed more or less just to make the REPL work, and have all of that be "builtin" the way that `sys` is; then have the rest available from the developers (including a default "full-fat" distribution), but in a few separately-obtainable pieces and independently versioned from the interpreter.
And possibly maintained by a third party like Boost, yeah. I don't know how important that is or isn't.
Some of us are fortunate to have never left vanilla JS.
Of course that limits my job search options, but I can't feel comfortable signing off on any project that includes more dependencies than I can count at a glance.
Python and Rust both have decent std lib, but it is just a matter of time before this happens in thoae ecosystems. There is nothing unique about this specific attack that could only happen in JavaScript.
>and go back to writing vanilla js
Lists of things that won't happen. Companies are filled with node_modules importers these days.
Even worse, now you have to check for security flaws in that JS that's been written by node_modules importers.
That or there could someone could write a standard library for JS?
C#, Java, and so on.
The blast radius is made far worse by npm having the concept of "postinstall" which allows any package the ability to run a command on the host system after it was installed.
This works for deps of deps as well, so anything in your node_modules has access to this hook.
It's a terrible idea and something that ought to be removed or replaced by something much safer.
I agree in principle, but child_process is a thing so I don't think it makes much difference. You are pwned either way if the package can ever execute code.
Simply avoiding Javascript won't cut it.
While npm is a huge and easy target, the general problem exists for all package repositories. Hopefully a supply chain attack mitigation strategy can be better than hoping attackers target package repositories you aren't using.
While there's a culture prevalent in Javascript development to ignore the costs of piling abstractions on top of abstractions, you don't have to buy into it. Probably the easiest thing to do is count transitive dependencies.
> Simply avoiding Javascript won't cut it.
But it will cut a large portion of it.
> These attacks may just be the final push I needed to take server rendering (without js) more seriously
Have fun, seems like a misguided reason to do that though.
A. A package hosted somewhere using a language was compromised!
B. I am not going to program in the language anymore!
I don't see how B follows A.
Javascript is badly over-used and over-depended on. So many websites just display text and images, but have extremely heavy javascript libraries because that's what people know and that is part of the default, and because it enables all the tracking that powers the modern web. There's no benefit to the user, and we'd be better off without these sites existing if there were really no other choice but to use javascript.
NPM does seem vastly over represented in these type of compromises, but I don't necessarily think that e.g. pypi is much better in terms of security. So you could very well be correct that NPM is just a nicer, perhaps bigger, target.
If you can sneak malware into a JavaScript application that runs in millions of browsers, that's a lot more useful that getting a some number servers running a module as part of a script, who's environment is a bit unknown.
Javascript really could do with a standard library.
> So many websites just display text and images
Eh... This over-generalises a bit. That can be said of anything really, including native desktop applications.
Is that true? The things people use native desktop applications for nowadays tend to be exactly those which aren't just neat content displays. Spreadsheets, terminals, text-editors, CAD software, compilers, video games, photo-editing software. The only things I can think of that I use as just text/image displays are the file-explorer and image/media-viewer apps, of which there are really only a handful on any given OS.
You could argue that spreadsheets and terminals are just text with extra features! I'm joking though, but web apps usually are more than just text and images too.
Rendering template partials server-side and fetching/loading content updates with HTMX in the browser seems like the best of all worlds at this point.
Until you need to write JavaScript?
Then write it. Javascript itself isn't the problem, naive third-party dependencies are.
Developers are perfectly fine with writing insecure JS all by themselves.
Which should be much less than what’s customary?
But that's the neat part, you don't!
Until you have to.
The only way to win is not to play.
Let me quit my job real quick. The endgame is probably becoming a monk, no kidding.
I considered becoming a Zen monk, but then I gave up the desire.
Why is this inevitable? If you use only easily verifyable packages you’ve lost nothing. The whole concept of npm automatically executing postinstall scripts was fixed when my pnpm started asking me every time a new package wanted to do that.
HTMX is full of JavaScript. Server-side-rendering without JavaScript is just back to the stuff Perl and PHP give you.
I don't think the point is to avoid Javascript, but to avoid depending on a random number of third-parties.
> Server-side-rendering without JavaScript is just back to the stuff Perl and PHP give you.
As well as Ruby, Python, Go, etc.
HTMX does not have external dependencies, only dev dependencies, reducing the attack surface.
Do you count LiveView (Elixir) in that assessment?
> The HTMX folks convinced me that I can get REALLY far without any JavaScript
HTMX is JavaScript.
Unless you meant your own JavaScript.
When we say 'htmx allows us to avoid JavaScript', we mean two things: (1) we typically don't need to rely on the npm ecosystem, because we need very few (if any) third-party JavaScript libraries; and (2) htmx and HTML-first allow us to avoid writing a lot of custom JavaScript that we would have otherwise written.
Took that route myself and I don't regret it. Now I can at least entirely avoid Node.js ecosystem.
Not for the frontend. esm modules work great nowadays with import maps.
> supply chain attacks
You all really need to stop using this term when it comes to OSS. Supply chain implies a relationship, none of these companies or developers have a relationship with the creators other than including their packages.
Call it something like "free code attacks" or "hobbyist code attacks."
“code I picked up off the side of the road”
“code I somehow took a dependency on when copying bits of someone’s package.json file”
“code which showed up in my lock file and I still don’t know how it got there”
All of which is true for far too many projects
I know CrowdStrike have a pretty bad reputation but calling them hobbyists is a bit rude.
I'm sure no offense was intended to hobbyists, but it was indeed rude
A supply chain can have hobbyists, there's no particular definition that says everyone involved must be a professional registered business.
I try to stay as far from web development as possible in my programming career (kernel/drivers and most recently reverse engineering) so maybe I'm ill-informed here but this npm thing seems to be uniquely terrible at security and i cannot fathom why the entire web seems to be automatically downloading updates from it and pushing them into production with no oversight.
I've always worked at companies where we use third party open source libraries utilities and its true that they get less-than-ideal amount of auditing when they get updated but at least we're not constantly pushing updates of to our customers solely for the sake of using the latest version. In fact usually they're out of date by several years which is also a problem but generally there'll be a guy following the mailing lists for updates in case there's a known exploit that needs to be patched.
I think all public package registries have this problem as it's not unique to npm.
The "blind" auto updating to latest versions seems to be also an issue here, simply you cannot trust it enough as there is (seemingly) no security vetting process (I mean if you get obfuscated gibberish pushed into a relatively sanely written codebase it should ring some alarms somewhere).
Normally you'd run tests after releasing new versions of your website but you cannot catch these infected parts if they don't directly influence the behavior of your functionality.
A lot of it is just that it's at the local maximum of popularity and relative user inexperience, so it's the juiciest target.
But also, npm was very much (like js you could argue) vibed into existence in many ways, eg with the idea of a lock file (eg reproducible builds) _at all_ taking a very long time to take shape.
We got lockfiles in 2016 (yarn) and 2017 (npm), before Go, Ruby, and others; I believe python is just getting a lockfile standard approved now.
You could already specify exact versions in your package.json, same as a Gemfile, but reality is that specifying dependencies by major version or “*” was considered best practice, to always have the latest security updates. Separating version ranges from the lock files, and requiring explicit upgrades was a change in that mindset – and mostly driven by containerization rather than security or dev experience.
This vulnerability was reported to NPM in 2016: https://blog.npmjs.org/post/141702881055/package-install-scr... https://www.kb.cert.org/vuls/id/319816 but the NPM response was WAI.
Acronym expansion for those-not-in-the-know (such as me before a web search): WAI might mean "working as intented", or possibly "why?"
Thank you. It's frustrating when people uncommon acronyms without explaining them.
AI is helpful for this, but I also built https://www.hackterms.com eight years ago for this exact reason.
Even if we didn't have post install scripts wouldn't the malware just run as soon as you imported the module into your code during the build process, server startup, testing, etc?
I can't think of an instance where I ran npm install and didn't run some process shortly after that imported the packages.
Many people have non-JS backends and only use npm for frontend dependencies. If a postinstall script runs in a dev or build environment it could get access to a lot of things that wouldn't be available when the package is imported in a browser or other production environment.
Malicious client-side code can still perform any user action, exfiltrate user data via cross-domain requests, and probe the user's local network.
I wonder why npm doesn't block pre/postinstall scripts by default, which pnpm and Bun (and I imagine others) already do.
EDIT: oh I scrolled down a bit further and see you said the exact same thing in a top-level comment hahah, my bad
It's crazy to me that npm still executes postinstall scripts by default for all dependencies. Other package managers (Pnpm, Bun) do not run them for dependencies unless they are added to a specific allow-list. Composer never runs lifecycle scripts for dependencies.
This matters because dependencies are often installed in a build or development environment with access to things that are not available when the package is actually imported in a browser or other production environment.
I'm also wondering why huge scale attacks like this don't happen for other package managers.
Like, for rust, you can have a build.rs file that gets executed when your crate is compiled, I don't think it's sandboxed.
Or also on other languages that will get run on development machines, like python packages (which can trigger code only on import), java libraries, etc...
Like, there is the post install script issue or course, but I feel like these attacks could have been just as (or almost as) effective in other programming languages, but I feel like we always only hear about npm packages.
All package managers are vulnerable to this type of attack, it just happens that npm is like 10+ times more popular than the others, so it gets targeted often.
Its only JS devs that constantly rebuild their system with full dependcy update, so they are the most attractive target.
It's a lot harder to do useful things with backend languages. JavaScript is more profitable as you can do the crypto wallet attacks without having to exploit kernel zero days.
It's trivial to run an exploit shell from almost any language when you have non-sandboxed code running on the target machine.
Seems like this is a fairly recent change, for Pnpm at least, https://socket.dev/blog/pnpm-10-0-0-blocks-lifecycle-scripts...
What has been the community reaction? Has allowing scripts been scalable for users? Or could it be described as people blindly copying and pasting allow commands?
I am involved in Python packaging discussions and there is a pre-proposal (not at PEP stage yet) at the moment for "wheel variants" that involves a plugin architecture, a contentious point is whether to download and run the plugins by default. I'd like to find parallels in other language communities to learn from.
In my experience, packages which legitimately require a postinstall script to work correctly are very rare. For the apps I maintain, esbuild is the only dependency which benefits from a postinstall script to slightly improve performance (though it still works without the script). So there's no scaling issue adding one or two packages to a whitelist if desired.
When the left-pad debacle happened, one commenter here said of a well known npm maintainer something to the effect of that he's an "author of 600 npm packages, and 1200 lines of JavaScript".
Not much has changed since then. The best counter-example I know is esbuild, which is a fully featured bundler/minifier/etc that has zero external dependencies except for the Go stdlib + one package maintained by the Go project itself:
https://www.npmjs.com/package/esbuild?activeTab=dependencies
https://github.com/evanw/esbuild/blob/755da31752d759f1ea70b8...
Other "next generation" projects are trading one problematic ecosystem for another. When you study dependency chains of e.g. biomejs and swc, it looks pretty good:
https://www.npmjs.com/package/@biomejs/biome/v/latest?active...
https://www.npmjs.com/package/@swc/types?activeTab=dependenc...
Replacing the tire fire of eslint (and its hundreds to low thousands of dependencies) with zero of them! Very encouraging, until you find the Rust source:
https://github.com/biomejs/biome/blob/a0039fd5457d0df18242fe...
https://github.com/swc-project/swc/blob/6c54969d69551f516032...
I think as these projects gain more momentum, we will see similar things cropping up in the cargo ecosystem.
Does anyone know of other major projects written in as strict a style as esbuild?
Part of the reason of my switch to using Go as my primary language is that there's this trend of purego implementations which usually aim towards zero dependencies besides the stdlib and golang.org/x.
These kind of projects usually are pretty great because they aim to work with CGO_ENABLED=0 so the libs are very portable and work with different syscall backends.
Additionally I really like to go mod vendor my snapshot of dependencies which is great for short term fixes, but it won't fix the cause in the long run.
However, the go ecosystem is just as vulnerable here because of lack of signing off package updates. As long as there's no verification possible end-to-end when it comes to "who signed this package" then there's no way this will get better.
Additionally most supply chaib attacks focussed on the CI/CD infrastructure in the past, because they are just as broken with just as many problems. There needs to be a better CI/CD workflow where signing keys don't have to be available on the runners themselves, otherwise this will just shift the attack surface to a different location.
In my opinion the package managers are somewhat to blame here, too. They should encourage and mandate gpg signatures, and especially in git commits when they rely on git tags for distribution.
> there's this trend of purego implementations which usually aim towards zero dependencies besides the stdlib and golang.org/x.
I'm interested in knowing whether there's something intrinsic to Go that encourages such a culture.
IMO, it might be due to the fact that Go mod came rather late in the game, while NPM was introduced near the beginning of NodeJS. But it might be more related to Go's target audience being more low-level, where such tools are less ubiquitous?
"A little duplication is better than a little dependency," -- Rob Pike
I think the culture was set from the top. Also, the fairly comprehensive standard library helps a lot. C# was in a similar boat back when I used it.
> I'm interested in knowing whether there's something intrinsic to Go that encourages such a culture.
I've also seen something similar with Java, with its culture of "pure Java" code which reimplements everything in Java instead of calling into preexisting native libraries. What's common between Java and Go is that they don't play well with native code; they really want to have full control of the process, which is made harder by code running outside their runtime environment.
I think it's important for managed/safe languages to have their own implementations of things, and avoid dropping down into C/C++ code unless absolutely necessary.
~13 years ago I needed to do DTLS (TLS-over-UDP) from a Java backend, something that would be exposed to the public internet. There were exactly zero Java DTLS implementations at the time, so I chose to write JNI bindings to OpenSSL. I was very unhappy with this: my choices were to 1) accept that my service could now segfault -- possibly in an exploitable way -- if there was a bug in my bindings or in OpenSSL's (not super well tested) DTLS code, or 2) write my own DTLS implementation in Java, and virtually guarantee I'd get something wrong and break it cryptographically.
These were not great choices, and I wished I had a Java DTLS implementation to use.
This is why in my Rust projects, I generally prefer to tell my dependencies to use rustls over native (usually OpenSSL) TLS when there's an option between the two. All the safety guarantees of my chosen language just disappear whenever I have to call out to a C library. Sure, now I have to worry about rustls having bugs (as a much less mature implementation), but at least in this case there are people working on it who actually know things about cryptography and security that I don't, and they've had third-party audits that give me more confidence.
> or 2) write my own DTLS implementation in Java, and virtually guarantee I'd get something wrong and break it cryptographically.
Java doesn't have constant time guarantees, so for at least the cryptographic part you have to call to a non-Java library, ideally one which implements the cryptographic primitives in assembly (unfortunately, even C doesn't have constant time guarantees, though you can get close by using vector intrinsics).
> I'm interested in knowing whether there's something intrinsic to Go that encourages such a culture.
I think it's because the final deliverable of Go projects is usually a single self-contained binary executable with no dependencies, whereas with Node the final deliverable is usually an NPM package which pulls its dependencies automatically.
With Node the final deliverable is an app that comes packaged with all its dependencies, and often bundled into a single .js file, which is conceptually the same as a single binary produced by Go.
Can you give an example? While theoretically possible I almost never see that in Node projects. It's not even very practical because even if you do cram everything into a single .js file you still need an external dependency on the Node runtime.
> usually an NPM package which pulls its dependencies automatically
Built applications do not pull dependencies at runtime, just like with golang. If you want to use a library/source, you pull in all the deps, again just like golang.
Not at runtime no, but at install time yes. In contrast, with Go programs I often see "install time" being just `curl $url > /usr/local/bin/my_application` which is basically never the case with Node (for obvious reasons).
C encourages such culture, too, FWIW.
Go sits at about the same level of abstraction as Python or Java, just with less OO baked in. I'm not sure where go's reputation as "low-level" comes from. I'd be curious to hear why that's the category you think of it in?
I'd argue that Go is somewhere in between static C and memory safe VM languages, because the compiler always tries to "monomorphize" everything as much as possible.
Generic methods are somewhat an antipattern to how the language was designed from the start. That is kind of the reason they're not there yet, because Go maintainers don't want boxing in their runtime, and also don't want compile time expansions (or JIT compilation for that matter).
So I'd argue that this way of handling compilation is more low level than other VM based languages where almost everything is JITed now.
Yes, eslint is particularly frustrating: https://npmgraph.js.org/?q=eslint
There are plenty of people in the community who would help reduce the number of dependencies, but it really requires the maintainers to make it a priority. Otherwise the only way to address it is to switch to another solution like oxlint.
I tried upgrading ESLint recently and it took me forever to fix all the dependency issues. I wish I never used ESLint prettier as now my codebase styling is locked into an ESLint config :/
Deno has a similar formatter to prettier and similar linter to eslint (with Typescript plugins) out-of-the-box. (Some parts of those written in Rust.) I have been finding myself moving to Deno more and more. I also haven't noticed too many reformatting problems with migrating from prettier to Deno. (If there are major changes, you can also add the commit to a .git-ignore-revisions file.)
Have you looked into biome? We recently switched at work. It’s fine and fast. If you overly rely on 3rd party plugins it might be hard but it covered our use case fine for a network based react app.
Way less dependencies too.
Even minor styling rule changes would result in a huge PR across our frontend so I tend to avoid any change in tooling. But using old tools is not the end of the world. I only upgrade ESLint because I had to upgrade something else.
Would omitting this commit from git blame solve the issue?
Oh that's a great idea. I forgot about git --ignore-revs
The answer is to not draw in dependencies for things you are easily able to write yourself. That would probably reduce dependencies by 2/3 or so in many projects. Especially, left-pad things. If you write properly self contained small parts and a few tests, you probably don't have to touch them much, and the maintenance burden is not that high. Compare that with having to check every little dependency like left pad and all its code and its dependencies. If a dependency is not strictly necessary, then don't do it.
> Very encouraging, until you find the Rust source
Those are the workspace dependencies, not the dependencies of the specific crates you may use within the project. You have to actually look closer to find that out, most of `swc-` crates have shallow dependency trees.
The downside is now I need to know Golang to audit my JavaScript project.
And it runs a post-install: node install.js
So I do really have to trust it or read all the code.
> Does anyone know of other major projects written in as strict a style as esbuild?
As in any random major project with focus on not having dependencies? SQLite comes to mind.
According to Aikido Security the attack has now targeted 180+ packages: https://www.aikido.dev/blog/s1ngularity-nx-attackers-strike-...
It's probably not trivial to implement and there's already a bunch of problems that need solving (e.g., trusting keys etc.) but... I think that if we had some sort of lightweight code provenance (on top of my head commits are signed from known/trusted keys, releases are signed by known keys, installing signed packages requires verification), we could probably make it somewhat harder to introduce malicious changes.
Edit: It looks like there's already something similar using sigstore in npm https://docs.npmjs.com/generating-provenance-statements#abou.... My understanding is that its use is not widespread though and it's mostly used to verify the publisher.
I think that depends on...how are these malicious changes actually getting into these packages? It seems very mysterious to me. I wonder why npm isn't being very forthcoming about this?
Letting upstream authors write code that the package manager runs at install time isn't a sane thing for package managers to allow. It promotes all kinds of hacky shit and makes packages harder to work with programmatically, and it also provides this propagation vector. Packages also shouldn't have arbitrary network access at build time for both of those two same reasons!
There's been a lot of talk here about selecting and auditing dependencies, which is fine and good. But this attack and lots of other supply chain attacks would also be avoided with a better-behaved package manager. Doesn't Deno solve this? Do any other JS package managers do some common-sense sandboxing?
Yes, migration is painful. Yes, granular permissions are more annoying to figure out than anything-can-do-anything. But is either as painful as vendoring/forking your dependencies without the aid of a package manager altogether? If you're really considering just copying and pasting instead of using NPM, maybe you should also consider participating in a saner package ecosystem. If you're ready to do the one, maybe you're ready to do the other.
I wonder who actually discovered this attack? Can we credit them? The phrasing in these posts is interesting, with some taking direct credit and others just acknowledging the incident.
Aikido says: > We were alerted to a large-scale attack against npm...
Socket says: > Socket.dev found compromised various CrowdStrike npm packages...
Ox says: > Attackers slipped malicious code into new releases...
Safety says: > The Safety research team has identified an attack on the NPM ecosystem...
Phoenix says: > Another supply chain and NPM maintainer compromised...
Semgrep says: > We are aware of a number of compromised npm packages
Mackenzie here I work for Aikido. This is a classic example of the security community all playing a part. The very first notice of this was from a developer named Daniel Pereira. He alerted Socket who did the first review of the Malware and discovered 40 packages. After, Aikido discovered an additional 147 packages and the Crowdstrike packages. I'm not sure how Step found it but they were the first to really understand the malware and that it was a self replicating worm. So multiple parties all playing a part kinda independent. Its pretty cool
question how does your product help in these situations? I imagine it'd require for someone to report a compromised package, and then you guys could detect it in my codebase?
Several individual developers seem to have noticed it at around the same time with Step and Socket pointing to different people in their blogs.
And then vendors from Socket, Aikido, and Step all seem to have detected it via their upstream malware detection feeds - Socket and Aikido do AI code analysis, and Step does eBPF monitoring of build pipelines. I think this was widespread enough it was noticed by several people.
Since so many vendors discovered these packages seemingly independently, you'd think that they would share those mechanisms with NPM itself so that those packages would never be published in the first place. But I guess that removes their ability to sell an "early alert" mechanism through their offerings...
NPM is owned by github/microsoft. I'm sure they could afford to buy one of these products or just build their own, but clearly security is not a thing they care about.
Somehow I didn't realize GitHub purchased npm in 2020. GitHub is the second word on npmjs.org. How did I not notice?

Can't help noticing, in the original article:
> The entire attack design assumes Linux or macOS execution environments, checking for os.platform() === 'linux' || 'darwin'. It deliberately skips Windows systems
If I were the conspiracy-minded sort I might jump to some wild conclusions here.
Whoever made the exploit probably doesn’t use windows.
I’m using windows again. By default windows has “power shell” which is not at all like bash and is (how do I say this diplomatically)… wanting.
I mean it says something the developed the Linux Subsystem for Windows, but it’s an optional install.
I watched an interview with Jeff Snover once and he said that they tried to make a unixy bash-like shell a few times and decided it was never going to fit in Windows. So they went a different way and took a lot of inspiration from OpenVMS.
So don’t expect PowerShell to be like a UNIX shell. It isn’t, and wasn’t meant to be one. It’s different, on purpose :)
What dont you like about powershell?
I'm a die hard linux user, and some years ago took a windows gig on a whim. I find powershell fantastic and the only thing that makes my role bearable. Now, one of the first things i install on Linux is powershell.
The awk equivalents in power-shell are horrific.
You don't find awk itself horrific in its own way?
Powershell is amazing. Just don't expect it to be posix. Using objects and structured data is leagues better than string parsing in posix shells imo.
Why should MS buy any of these startups when a developer (not any automated tech) found the malware? It looks like these startups did after-the-fact analysis for PR.

Points to this, which does look like the first mention.
https://github.com/scttcper/tinycolor/issues/256
Usually security companies monitor CVEs and the security mailing lists. That's how they all end up releasing the blog posts at the same time. It's because they are all using the same primary source.
In the story about the Nx compromise a few weeks ago someone posted a neat script that uses bubblewrap on Linux to run tools like npm more safely by confining their filesystem access. https://news.ycombinator.com/item?id=45034496
I modified the script slightly based on some of the comments in the thread and my own usage patterns:
Put this in `~/.local/bin` and symlink it to `~/.local/bin/npm` and `~/.local/bin/yarn` (and make sure `~/.local/bin` is first in your `$PATH`). I've been using it to wrap npm and yarn successfully in a few projects. This will protect you against some attacks that use postinstall scripts to do nefarious things outside the project.> --bind "${PWD}" "${PWD}"
Pardon my ignorance, but couldn't a malicious actor just redefine $PWD before calling a npm script?
The above script wraps npm. PWD gets evaluated before npm is called (so PWD is expanded in the "outside" environment).
Of course, if your malicious actor has access to your environment already, they can redefine PWD, but that's assuming you're already compromised. This bwrap script is to avoid that malicious actor running malicious install scripts in the first place.
However, I don't think it protects you against stuff like `npm install compromised-executable && node_modules/.bin/execute-compromised-executable` – then you'd have to bwrap that second call as well. Or just bwrap bash to get a limited shell.

Clever name... but I would have expected malware authors to be a bit less obvious. They literally named their giant worm after a giant worm.

Yep, even malware can be bloated. That's in the spirit of NPM I guess...
I suppose it's only a matter of time before one of these supply chain attacks unintentionally pulls in a second, unrelated supply chain attack.

Malwares have to follow Moore's law, tequila virus was ~2.6kb in 1991.
For years everyone in the programming community has been pushing for convenience and features and code reuse and its got to the point I think the ease of adding a third party package from the languages package manager or github needs to be seriously questioned by security conscious devs. Perhaps we made the wrong things easy.
I think these kinds of attack would be strongly reduced if js had a strong standard library.
If it was provided, it would significantly trim dependency trees of all the small utility libraries.
Perhaps we need a common community effort to create a “distro” of curated and safe dependencies one can install safely, by analyzing the most popular packages and checking what’s common and small enough to be worth being included/forked.

Ever seen XKCD #927? (https://xkcd.com/927)
Joking aside, I don't think there ever really was a lack of initiatives by entities (communities, companies, whatever) to create some sort of standard library (we typically tend to call them frameworks). There's just simply too much diversity, cultures and subcultures within the whole JavaScript sphere to ever get a global consensus on what that "standard" library then should look like. Not to mention the commercial entities with very real stakes in things they might not want to relinquish to some global unity consensus (as it may practically hurt their current bottom line).
Is there any way to install CLI tools from npmjs without being affected by a recent compromise?
Rust has `cargo install --locked`, which will use the pinned versions of dependencies from the lockfile, and these lockfiles are published for bin packages to crates.io.
But it seems npmjs doesn't allow publishing lockfiles, neither for libraries nor for CLI tools, so if you try to install let's say @google/gemini-cli, it will just pull the latest dependencies that fit the constraints in package.json. Is that true? Is it really this bad? If you try to install a CLI tool on a bad day when half of npmjs is compromised, you're out of luck?
How is that acceptable at all?
Lock files wouldn't work if they were locking transitive dependencies; otherwise the version solver would not have any work to actually do and you'd have many, many versions of the same package rather than a few versions that satisfy all of the version range constraints.
Lots of good ideas since last week, the one I like most being that published packages, especially those that are high in download count, don't actually go publish for a while until after publishing, allowing security scanners to do their thing.
In the Rust ecosystem, you only publish lock files for binary crates. So yeah then you get churn like https://github.com/cargo-bins/cargo-binstall/releases/tag/v1... bumping transitive deps, but this churn/noise doesn't exist for library crates - because the lock file isn't published for them.
lib crates have been checking in their Cargo.lock for a while now.
https://github.com/rust-lang/cargo/pull/12382
That Cargo.lock will only be used for the library's own CI though (and also for development if you git clone it). It will not be used by downstream dependencies at all.
npm will use your lockfile if it’s present, otherwise yeah it’s pretty much whatever is tagged and latest at the time (and the version doesn’t even have to change). If npm respected every upstream lockfile, then it could never share a single version that satisfied all dependencies. The bigger issue here is that npm has such unrestricted and unsupervised access to the entire environment at all.
> If npm respected every upstream lockfile, then it could never share a single version that satisfied all dependencies.
I'm asking in the context of installing a single CLI tool into ~/bin or something. There's no requirement to satisfy all dependencies, because the only dependency I care about is that one CLI tool. All I want is an equivalent of what `cargo install --locked` does — use the top-level lockfile of the CLI tool itself.
That sounds pretty reasonable: npm should allow bundling the lockfile with things that are marked with the type of "project", and whether it actually uses them depending on whether other locked constraints are overriding it. So instead of one lockfile, a prioritized list of them. The UX of dealing with that list could be a sticky wicket though, and npm isn't known for making this stuff easy to begin with.
npm itself does not know that what you are installing is a CLI tool.
Good CLI tools are bundled before release so they are zero-dependency as far as npm is concerned, which is ideal imho for all CLI tools, but many don't do that.
Last week someone wrote a blog post saying "We dodged a bullet" because it was only a browser-based crypto wallet scrape
Guess we didn't dodge this one
We didn't really dodge a bullet. We put a bullet named 'node' in the cylinder of a revolver, spun it, pointed the gun at our head, and pulled the trigger. We just happened to be lucky enough that we got an empty chamber.
I knew npm was a train wreck when I first used it years ago and it pulled in literally hundreds of dependencies for a simple app. I avoid anything that uses it like the plague.
I can tell a lot about a dev by the fact that they single out npm/js for this supply chain issue.
Lots of languages ecosystems have this problem, but it is especially prominent in JS and lies on a spectrum. For comparison, in the C/C++ ecosystem it is prominent to have libraries advertising that they have zero dependencies and header only or one common major library like Boost.
What other language ecosystems have had this happen systematically? This isn't even the first time this month!
NPM is the most popular, so it happens the most frequently. All of the other ecosystems are just as susceptible.
Unix had a big scare last year because of XZ Utils.
https://en.wikipedia.org/wiki/XZ_Utils_backdoor
Python/PyPi.
RubyGems is susceptible too.
Rust.
Go has this issue
The JavaScript ecosystem has a major case of import-everything disease that acts as a catalyst for supply chain attacks. left-pad as one example of many.
That they’ve coded in more than one language?
Just more engineering leaning than you. Actual engineers have to analyze their supply chains, and so makes sense they would be baffled by NPM dependency trees that utterly normal projects grow into in the JavaScript ecosystem.
Good thing that at scale, private package repositories or even in-house development is done. Personally, I would argue that an engineer unable to tell apart perfect from good, isn't a very good engineer in my book, but some engineers are unable to make compromises.
Do you think companies using node don't analyze supply chains? That's nonsense. Have you cargo installed a rust app recently? This isn't just a js issue. This needs to be solved across the industry and npm frankly has done a horrible job at it. We let people with billions of downloads a month with recently changed password/2fa publish packages? Why don't we pool assets as a collective to scan newly published packages before they're allowed to be installed? These types of things really should exist across all package registries (and my really hot take is that we probably don't need a registry for every language, either!).
It is solved across the industry for those who care. If you use cargo, npm, or a python package manager, you may have a service that handles static versioning of dependencies for security purposes. If you don't, you aren't generally working in a language that encourages so much package use.
2FA would certainly help, however you'd still have malware like these silently updating code and waiting for the next release.
We'd have to rely on the developer to notice, and check every line of code they ship, which might be the norm but certainly not 100% of cases.
> Do you think companies using node don't analyze supply chains?
I _know_ many don’t. In fact suggesting doing it is a good way to be looked at like a crazy person and be told something like “this is a yes place not a no place.”
I think it’s just that a lot of old men don’t like how popular it has become with script kiddies.
"I knew you weren't a great engineer the moment you started pulling dependencies for a simple app"
You realize my point right? People are taught to not reinvent the wheel at work (mostly for good reasons) so that's what they do, me and you included.
You ain't gonna be bothered to write html and manual manipulation, the people that will give you libraries to do so won't be bothered reimplementing parsers and file watchers, file watcher writers won't be bothered reimplementing file system utils, file system utils developers won't be bothered reimplementing structured cloning or event loops, etc, etc.
I myself just the other day had the task of converting HTML to markdown, because I don't remember whether it was Jira or Github APIs that returns comments as HTML and despite it being mostly few hours of work that would get us 90% there everybody was in favor of pulling a dependency to do so (with its own dependencies) and thus further exposing our application to those risks.
Pause, you could write an HTML to markdown library in half a day? Like, 4 hours? Or 12? Either way damn
One that gets me 90% there would take me few hours, one that gets me 99% there few months, which is why eventually people would rather pull a dependency.
Or about 15 minutes with an LLM?
https://github.com/williamcotton/markdown-to-html-llm
I love how it took you very short to implement...the wrong thing.
> I myself just the other day had the task of converting HTML to markdown
> you could write an HTML to markdown library in half a day
LOL! Good point, my friend.
Claude Code just added support for HTML to Markdown. Seems to work?
In any case, not following the point you're trying to make.
LLMs are pretty good at greenfield projects and especially if they are tasked with writing something with a lot of examples in the training data. This approach can be used to solve the problem of supply-chain attacks with the downside being that the code might not be as well written and feature complete as a third-party package.
I use LLMs too, but don't share your opinion fully.
In less time than that, you could `git clone` the desired open source package, and text search & replace the author's name with your own.
And then still be subject to supply-chain attacks with all of the dependencies in whatever open source package you're cloning?
you are aware that the app you just wrote with Claude pulls in dependencies, yes?
Not for the parser, only for the demo server! And I guess the dev dependencies as well, but with a much smaller surface area. But yeah, I don't think a TypeScript compiler is within the scope of an LLM.
So basically you live JavaScript free?
as much as i can yes.
I try to avoid JS, as it is a horrible language, by design. That does include TS, but it at least is useable, but barely - because it still tied to JS itself.
Off-topic, but I love how different programmers think about things, and how nothing really is "correct" or "incorrect". Started thinking about it because for me it's the opposite, JS is an OK and at least usable language, as long as you avoid TS and all that comes with it.
Still, even I who'd call myself a JavaScript developer also try to avoid desktop applications made with just JS :)
JS's issue is that it allows you to run an objectively wrong code without throwing explicit error to the user, it just fails silently or does something magical. Seems innocent, until you realize what we use JS for, other than silly websites or ERP dashboards.
It is full of gotchas that serves 0 purpose nowadays.
Also remember that it is basically a Lisp wearing Java skin on top, originally designed in less than 2 weeks.
Typescript is one of few things that puts safety barrier and sane static error checking that makes JS bearable to use - but it still has to fall down to how JS works in the end so it suffers from same core architectural problems.
> JS's issue is that it allows you to run an objectively wrong code without throwing explicit error to the user, it just fails silently or does something magical. Seems innocent, until you realize what we use JS for, other than silly websites or ERP dashboards.
What some people see as a fault, others see as a feature :) For me, that's there to prevent entire websites from breaking because some small widget in the bottom right corner breaks, for example. Rather than stopping the entire runtime, it just surfaces that error in the developer tools, but lets the rest to continue working.
Then of course entire web apps crash because one tiny error somewhere (remember seeing a blank page with just some short error text in black in the middle? Those), but that doesn't mean that's the best way of doing things.
> Also remember that it is basically a Lisp wearing Java skin on top
I guess that's why I like it better than TS, that tries to move it away from that. I mainly do Clojure development day-to-day, and static types hardly ever gives me more "safety" than other approaches do. But again, what I do isn't more "correct" than what anyone else does, it's largely based on "It's better for me to program this way".
>it's there to prevent entire websites from breaking because some small widget in the bottom right corner breaks, for example.
the issue is that it prevents that, but also allows you to send complete corrupt data forward, that can create horrible cascade of errors down the pipeline - because other components made assumption about correctness of data passed to them.
Such display errors should be caught early in development, should be tested, and should never reach prod, instead of being swept under the rug - for anything else other than prototype.
but i agree - going fully functional with dynamic types beats average JS experience any day. It is just piling up more mud upon giant mudball,
IME, JSDoc is sufficient for type checking.
TS is just too much overhead for the marginal gains.
> JS is an OK and at least usable language, as long as you avoid TS and all that comes with it.
Care to explain why?
My view is this: since you can write plain JS inside TS (just misconfigure tsconfig badly enough), I honestly don’t see how you arrive at that conclusion.
I can just about understand preferring JS on the grounds that it runs without a compile step. But I’ve never seen a convincing explanation of why the language itself is supposedly better.
Lucky you. I keep coming back to it because jobs and even for desktop apps a native webview beats everything else.
We fcked up with js, big time and its with us forever now
For game dev too - all game engines suck. <canvas/> FTW.
I was hyped for wasm because i thought it was supposed to solve this problem, allowing any programming language to be compiled to run in browsers.
But apparently they only made it do like 95% of what JS does so you can't actually replace js with it. To me it seems like a huge blunder. I don't give a crap about making niche applications a bit faster, but freeing the web from the curse of JS would be absolutely huge. And they basically did it except not quite. It's so strange to me, why not just go the extra 5%?
The DOM is fundamentally dependent upon JS shaped data structures and garbage collection. They are BFFs.
Any attempt to bypass this will be perilous.
So we'd need a new DOM, seems feasible
Maybe its something about sharing memory with the js that would introduce serious vulnerabilities so they can't let wasm code have access to everything.
The only way to remove Js is to create a new browser that doesn't use it. Fragments the web, yes and probably nobody will use it
That 5% of js glue code necessary right now is just monumentally difficult to get rid of, it's like a binary serialization / interface (ABI) of all DOM/BOM APIs and these APIs are huge, dynamic, callback-heavy and object-oriented. It's much easier to have that glue compiler generated, which you can already do right now (you can write your entire web app in rust if you want):
https://github.com/wasm-bindgen/wasm-bindgen https://docs.rs/web-sys/latest/web_sys/
This is also being worked on, in the future this 5% glue might eventually entirely disappear:
> Designed with the "Web IDL bindings" proposal in mind. Eventually, there won't be any JavaScript shims between Rust-generated wasm functions and native DOM methods
out of sincere curiosity, which one is a great programming language to you?
depends on use case, i don't think one language can fit all cases. 100% correctness is required for systems, but it is a hindrance in non-critical systems. or robust type systems require high compilation times which hurt iterating on the codebase.
systems? rust - but it is still far from perfect, too much focus on saving few keystrokes here and there.
general purpose corporate development? c# - despite current direction post .net 5 of stapling together legacy parts of .net framework to .net core. it does most things good enough.
scripting, and just scripting? python.
web? there's only one, bad, option and that's js/ts.
most hated ones are in order: js, go, c++, python.
go is extremely infuriating, there was a submission on HN that perfectly encapsulated my feelings about it, after writing it for a while: https://fasterthanli.me/articles/i-want-off-mr-golangs-wild-...
Under a submission like this you picked Rust, that is neat.
I mean, it's hard to avoid indirectly using things that use npm, e.g. websites or whatever. But it's pretty easy to never have to run npm on your local machine, yes.
You can write javascript without using npm...
This seems like a great opportunity for someone to push a smaller but fully audited subset of the npm repos.
Corporations would love it.
So, other packaging environments have a tendency to slow down the rate of change that enters the user's system. Partly through the labor of re-packaging other people's software, but also as a deliberate effort. For instance: Ubuntu or RedHat.
Is anyone doing this in a "security as a service" fashion for JavaScript packages? I imagine a kind of package escrow/repository that only serves known secure packages, and actively removes known vulnerable ones.
I've worked in companies that do this internally, e.g., managed pull-through caches implemented via tools like Artifactory, or home-grown "trusted supply chain" automation, i.e., policy enforcement during CI/CD prior to actually consuming a third-party dependency.
But what you describe is an interesting idea I hadn't encountered before! I assume such a thing would have lower adoption within a relatively fast-moving ecosystem like Node.js though.
The closest thing I can think of (and this isn't strictly what you described) is reliance on dependabot, snyk, CodeQL, etc which if anything probably contributes to change management fatigue that erodes careful review.
> managed pull-through caches implemented via tools like Artifactory
This is why package malware creates news, but enterprises mirroring package registries do not get affected. Building a mirroring solution will be pricey though mainly due to high egress bandwidth cost from Cloud providers.
How does a pull-through cache prevent this issue? Wouldn’t it also just pull the infected version from the upstream registry?

No direct relation to the specific attack on debug/chalk/error-ex/etc that happened 7 days ago.

Seems to be a separate incident?
Separate? Yes. Unrelated? Hard to tell.
It's unrelated in every observable technical way, but related in that it's a bit crazy how often this is happening to npm lately.
I'm glad it wasn't this particular attack that hit me last week.
Warning: LLM-generated article, terribly difficult to follow and full of irrelevant details.
We've seen many reports of supply chain attacks affecting NPM. Are these symptoms of operational complexity, which can affect any such service, or is there something fundamentally wrong with NPM?
It's actually relatively simple.
Adding dependencies comes with advantages and downsides. You need to strike a balance between them. External libraries can help implement things that you better don't implement yourself, so the answer is certainly not "no dependencies". But there are downsides and risks, and the risks grow with the number of dependencies.
In the world of NPM, people think those simple truths don't apply to them and the downsides and risks of dependencies can be ignored. Then you end up with thousands of transitive dependencies.
They're wrong and learn it the hard way now.
You can't put this all on the users. The JS/node/npm projects have been mismanaged since the start.
node should have shipped "batteries included" after the left-pad incident. There was a boneheaded attachment to small stdlib, which you could put down to youthful innocence, except that it's been almost 10 years.
The TC39 committee which controls the design of JS stdlib and the node maintainers basically both act like the other one doesn't exist.
NPM was never designed with security in mind. It's a dirty hack that somehow became the most popular package manager.
The dependency hell is a reflection of the massive egos of the people involved in the multiple organizations. Python doesn't have this problem because it's all centralized under one org with a single vision.
Apparently Maven has 61.9M indexed packages. As Java has a decent standard lib, mini libs like leftpad are not contributing to this count. NPM has 3.1M packages. Many are trivially simple. Those stats would suggest that NPM has disproportionately more issues than other services.
I would argue that is only one of the many issues with the JS/TS/NPM ecosystem. Many of the other problems have been normalized. The constant security issues are highly visible.
> Apparently Maven has 61.9M indexed packages.
Where did you see that number? Maven central says it has about 18 million [1] packages. Maybe with all versions of those 18 million packages there are about 62 million artifacts?
While the Java ecosystem is vastly larger, in Java (with Maven, Gradle, Bazel, etc.) it is not common to use really small libraries. So you end up with vastly less transitive dependencies in your projects.
[1] https://mvnrepository.com/repos/central
That is correct.
On Maven, I restrict packages to Spring and Apache. As opposed to NPM, where even big vendors can depend on hundreds of small ones.
This. You would expect some of the mature packages to be quite diligent about dependencies, but they are the one pulling random stuff for a minor feature. then the transitive dependencies adds like GBs of files to your project.
There is a guy (ljharb) who is literally on TC39 - JavaScript specification committee - who is maintaining like 600 packages full of polyfills/dependencies/utilities.
It's just javascript being javascript.
There was a huge uproar about that guy specifically and deep dependency graphs in general a year ago. A lot has already changed for lots of the popular frameworks and libraries. Dependency graphs are already much slimmer. The cultural change is happening, but we can't expect it to happen all at once.
Irrelevant here. You use eslint-plugin-import with its 60 dependencies; One dependency or 60 is irrelevant because you only need one token: his. They're all his packages.
The problem with that guy is that the dependencies are useless to everyone except his ego.
That wouldn't be a problem if there was proper package signing and the polyfill packages were hosted under a package namespace owned by the javascript specification committee.
Just spit-balling here, but it seems that the problem is with the pushing to NPM, and distribution from NPM, rather than the concept of NPM. If NPM required some form of cryptographically secure author signing, and didn't distribute un-signed packages, then there is at least a chain of responsibility that can be followed.
It's the entire blase nature of js development in general.
With Javascript, yes, but also with all programming-language package managers and software development culture in general. There's too huge of an attack surface, and virtually no attack mitigation. It's a free for all. These are solvable problems, though. Distros have been doing it the right way for decades, and we could do it even better than that. But being lazy is easier. Until people are forced to improve - or there's some financial incentive - they don't.
This has been brewing for a long time. Maven, CPAN before it.
Maybe some of these systems have better protection from counterfeiting, and probably they all should. But as the number of packages you use goes up, the surface area does too. As a Node developer the… permissiveness of the culture has always concerned me.
The trick with playing with fire is understanding how fire works, respecting it, and keeping the tricks small. The bigger you go, the more the danger.
It's just where the users and the juicy targets are.
NPM packages are used by huge Electron apps like Discord, Slack, VS Code, the holy grail would be to somehow slip something inside them.
It's both that and a culture of installing a myriad of constantly-updating, tiny libraries to do basic utility functions. (Not even libraries, they're more like individual pages in individual books).
In our line-of-business .NET app, we have a logger, a database, a unit tester, and a driver for some specialty hardware. We upgrade to the latest version of each external dependency about once per year (every major version) to avoid accruing tech debt. They're all pinned and locally hosted, nuget exists but we (like most .Net developers) don't use it to the extent that npm devs do. We read the changelogs - all four of them! - and manually update.
I understand that the NPM ecosystem works differently from a "batteries included" .Net environment for a desktop app, but it's not just about where the users are. Line of business code in .Net and Java apps process a lot of important data. Slipping a malicious package into pypi could expose all kinds of juicy, proprietary data, but again, it's less about the existence of a package manager and more about when and how you use it.
> Slipping a malicious package into pypi could expose all kinds of juicy, proprietary data
> In July 2024, Bittensor users were the victims of an $8 million hack. The Bittensor hack was an example of a supply chain hack using PyPI. PyPI is a site that hosts packages for the Python programming language
https://www.halborn.com/blog/post/explained-the-bittensor-ha...
Yes, there are hackers on every platform... but it feels like there's an NPM compromise announced about once a week.
We don't see these attacks nearly as severe or frequent on Maven, which is a much older package management solution. Maven users would be far more attractive targets given corporates extensively run Java.
Number of packages doesn’t mean much. If you can get your code into just one Javascript package you could have it run on billions of browsers. With Java it’s hard to get the same distribution (although the log4j vulnerability shows it’s not entirely impossible).
It is also, in my humble but informed opinion, where you will find the least security concious programs, just because of the breadth of it's use and myriad of deployments.
It's the new pragmatic choice for web apps and so it's everyone is using it, from battle hardened teams to total noobs to people who just don't give a shit. It reminds me of Wordpress from 10 years ago, when it was the goto platform for cheap new websites.
Every NPM turd should be run with bubblewrap or a similar sandbox toolkit at least.
So do you expect other supply chain services that also supply juicy targets to be affected? I mean, we live in a bubble here in HN, so not seeing something in the front page doesn't mean it doesn't exist or it doesn't happen, but the feeling is that NPM is particularly more vulnerable than other services, correct me if I'm wrong.
NPM isn’t perfect but no, it’s fundamentally self inflicted.
Community is very happy to pick up helper libraries and by the time you get all the way up the tree in a react framework you have hundreds or even thousands of packages.
If you’re sensible you can be fine just like any other ecosystem, but limited because one wrong package and you’ve just ballooned your dependency tree by hundreds which lowers the value of the ecosystem.
Node doesn’t have a standard library and until recently not even a test runner which certainly doesn’t help.
If your sensible with node or Deno* you’ll somewhat insulated from all this nonsense.
*Deno has linting,formatting,testing & a standard library which is a massive help (and a permission system so packages can’t do whatever they want)
> is there something fundamentally wrong with NPM?
Its users don't check who the email is from
My main takeaway from all of these is to stop using tokens, and rely on mechanisms like OIDC to reduce the blast radius of a compromise.
How many tokens do you have lying around in your home directory in plain text, able to be read by anything on your computer running as your user?
> How many tokens do you have lying around in your home directory in plain text, able to be read by anything on your computer running as your user?
Zero? How many developers have plain-text tokens lying around on disk? Avoiding that been hammered into me from every developer more senior than me since I got involved with professional software development.
You're sure you don't have something lying around in ~/.config ? Until recently the github cli would just save its refresh token as a plain text file. AWS CLI loves to have secrets sitting around in a file https://docs.aws.amazon.com/cli/latest/userguide/cli-configu...
I don't use AWS and looking in ~/.config/gh I see two config files, no plain-text secrets.
With that said, it's not impossible some tool leaks their secrets into ~/.local, ~/.cache or ~/.config I suppose.
I thought they were referencing the common approach of adding environment variables with plaintext secrets to your shell config or as an individual file in $HOME, which been a big no-no for as long as I can remember.
I guess I'd reword it to "I'm not manually putting any cleartext secrets on disk" or something instead, if we wanted it to be 100% accurate.
> How many developers have plain-text tokens lying around on disk?
Most of them. Mainly on purpose, (.env files) but many also accidentally. (shell history with tokens in the commands)
Exactly. There are tools that allow debugging production environments without having to have the credentials on your disk.
I recommend Envie: https://github.com/ilmari-h/envie
It's more convenient than having a bunch of .env.prod, .env.staging files laying around, not to mention more secure.
Isn't this quite hard to achieve on local systems, where you don't have a CI vault automation to help?
Most popular apps today have integrations to allow reading secrets from external programs. If not, they can take them from environment variables. Both those can then be loaded from a password manager, so the secret never lands on disk in plaintext.
Your program (or your shell) opens. It runs a program to ask the password manager for a secret. Your password manager prompts you to authorize unsealing the secret. You accept or deny. The secret is passed to the program that asked for it. Works very well with 1Password and tools like git, ssh, etc, or simply exporting the secret to an environment variable, either in a script or bashrc file.
Other programs also support OIDC, such as with git credential helper plugins, or aws sso auth.
I'd argue the reverse is true. On your local system, which only need to operate when a named user with a (hopefully) strong password is present, you can encrypt the secrets with the user's login password and the OS can verify that it's handing the secret out to the correct binary before doing so. The binary can also take steps to verify that it is being called directly from a user interaction and not from a build script of some random package.
The extent to which any of this is actually implemented varies wildly between different OSes, ecosystems and tools. On macOS, docker desktop does quite well here. There's also an app called Secretive which does even better for SSH keys - generating a non-exportable key in the CPU's secure enclave. It can even optionally prompt for login password or fingerprint before allowing the key to be used. It's practically almost as secure as using a separate hardware token for SSH but significantly more convenient.
In contrast, most of the time the only thing protecting the keys in your CI vault from being exfiltrated is that the malware needs to know the specific name / API call / whatever to read them. Plenty of CI systems you don't even need that, because the build script that uses the secrets will read them into environment variables before starting the build proper.
It's not that hard if it's something you decide you care about and want to solve. Like diggan mentions, there's many tools, some you already might use, that can be used to inject secrets into applications that's not too onerous to use in your development workflow.
I don't think so? I don't even know what a "CI vault automation" is, I store my credentials and secrets in 1Password, and use the CLI to get the secrets for the moments they're needed, I do all my development locally and things seem fine.
How do you manage secrets for your projects?
One option is pass, which is a shell script that uses GPG to manage passwords for command line tools. You can put the password store into a git repository if you need to sync it across machines.
Wait, what? "put the password store into a git repository"?!
The store in the case of pass, is a plain text file, whose contents are encrypted strings. If you trust the encryption, you can put it anywhere you like. Keep the keys secret and safe, though!
Until you have to fire one of your disgruntled employees, who has a copy of all your secrets that you now need to rotate.
A repository that an attacker only needs to get access to once, after which they can perform offline attacks against at their leisure.
A repository that contains the history of changed values, possibly making the latter easier, if you used the same encryption secret for rotated values.
This is an awful idea. Use a proper secret management tool you need to authenticate to using OIDC or Passkeys, and load secrets at runtime within the process. Everything else is dangerous.
Using a password manager for fetching them when needed. 1Password in my case, but I'm sure any password manager can be used for storing secrets for most programming projects.
I was thinking about one more case, if you are using 1password as a cli tool. Let's say you "op run -- npm dev". If there's a malicious node modules script, it would of course be able to get the env variables you intended to inject, but would it also be able to continue running more op commands to get all your other secrets too if you have started a session?
Edit: Testing 1Password myself, with 1password desktop and shell, if I have authed myself once in shell, then "spawn" would be able to get all of my credentials from 1Password.
So I'm not actually sure how much better than plaintext is that. Unless you use service accounts there.
Fun fact : Bitwarden’s cli is written in JavaScript and needs Node.js to run.
Which programming languages/frameworks do you use? Do you use 1Password to load secrets to env where you run whatever thing you are working on? Or does the app load them during boot?
A bunch, ranging from JS to Clojure and everything in-between, depends on the project.
The approach also depends on the project. There is a bunch of different approaches and I don't think there is one approach that would work for every project, and sometimes I requires some wrangling but takes 5-10 minutes tops.
Some basic information about how you could make it work with 1Password: https://developer.1password.com/docs/cli/secrets-environment...
How long have you been using that method? I didn't feel it's been very popular so far, although it makes a lot of sense. I've always seen people using gitignored .env files/config dirs in projects with many hardcoded credentials.
A good habit, but encryption won't save you in all cases because anything you run has write access to .bashrc.
Frankly, our desktop OSes are not fit for purpose anymore. It's nuts that everything I run can instantly own my entire user account.
It's the old https://xkcd.com/1200/ . That's from 2013 and what little (Flatpak, etc.) has changed has only changed for end users - not developers.
Blog author company's runner detects anomalies in them, but we shouldn't need a product for this.
Detecting outbound network connection during an npm install is quite cheap to implement in 2025. I think it comes down to tenant and incentives, if security is placed as first priority as it should, for any computing service and in particular for supply chain like package management, this would be built in.
One thing that comes to mind that would make it a months long deabte is the potential breakage of many packages. In that case as a first step just make an eye catching summary post install, with gradual push to totally restriction with something like a strict mode, we've done this before.
Which, reminds me of another long standing issue with node ecosystem toolings, information overload. It's easy to bombard devs with thesis character count then blame them for eventually getting fatigue and not reading the output. It takes effort to summarize what's most important with layered expansion of detail level, show some.
"Outbound network connection at npm install" is just one of many ways malware in NPM package can manifest itself.
E.g. malware might be executed when you test code which uses the library, or when you run a dev server, or on a deployed web site.
The entire stack is built around trusting a code, letting it do whatever it wants. That's the problem.
Yes, cybersecurity is absolutely a cost center. You can pay for it the easy way, the hard way, or the very hard way. Looks like we're fixing NPM the very hard way.
Anyone know if there is a public events feed/firehouse for npm ecosystem system? Similar to GitHub public events feed?
We, at ClickHouse, love big data and it would be super cool download and analyse patterns of all these data & provide some tooling to help with combatting this wide spread issue.
Code signing, 2FA, and reducing dependencies are all incomplete solutions. What we need is fine-grained sandboxing, down to the function and type level. You will always be vulnerable as long as you're relying on fallible humans (even yourself) to catch or prevent vulnerabilities.
Apparently they've tried to implement this in JavaScript but the language is generally too flexible to resist a malicious package running in the same process.
We need to be using different languages with runtimes that don't allow privileged operations by default.
That doesn’t solve it either. If you need to grant hundreds of permissions, people will just hand-wave them all—remember the UAC debacle in Windows Vista? I like Denos approach way better; and you could also ask why any application can just read files in your home folder, or make network requests to external hosts. OSes really are part of the equation here.
Languages/VMs should support capability-based permissions for libraries, no library should be able to open a file or do network requests without explicit granular permissions.
So glad I left JS for backend last year. It was a big effort switching to a new language and framework (still is) but it looks like so far the decision was worth it.
I'm still looking at Bun and all the effort they're doing with built-in APIs to reduce (and hopefully eliminate) third party deps. I would prefer using TS for the whole stack if possible but not at the expense of an insecure backend ecosystem.
Just curious, what did you switch to?
dotnet
I’m not sure language package mangers were a good idea at all. Dependencies were supposed to be painful. If the language needed some functionality built in it was supposed to go into the standard library, I understand that for JS this isn’t feasible.
Nah, package managers are always the "civilization" moments of programming.
There was a very similar discussion on lobsters the other day. You might be interested in reading it.
In general, I agree with the idea that writing everything yourself results in a higher quantity of low quality software with security issues and bugs, as well as a waste of developers' time. That said, clearly supply chain attacks are a very real threat that needs to be addressed. I just don't think eliminating package managers is a good solution.

I was just reading an article in Foreign Affairs that was discussing a possible future with an increased separation of science and technological developments between China and The West. And it occurred to me, what would such a siloed landscape mean for OSS and basically the whole web infrastructure as it is today, shared and open for anyone in any country. I think this kind of malware becoming pervasive could be the failure state if this future becomes reality.
May I ask which article it was? The Once and Future China?
Thats the one
I always thought open source in a purely profit driven society was always a bit contradictory, but it's like the wikipedia. There is just something innate in people that makes them care for their craftsmanship and their community with zero profit incentive, despite the prevailing ideology telling us that it ought to be impossible and surely about to collapse any moment now. OSS will prevail no matter Microsoft's disastrous and irresponsible stewardship of a smallish portion of it.
post-install seems like it shouldn't be necessary anyway, let alone need shell access. What are legitimate JS packages using this for?
From what I've seen, it's either spam, telemetry, or downloading prebuilt binaries. The first two are anti-user and should not exist, the last one isn't really necessary — swc, esbuild, and typescript-go simply split native versions into separate packages, and install just what your system needs.
Use pnpm and whitelist just what you need. It disables all scripts by default.
Does that even matter?
The malware could have been a JS code injected into the module entry point itself. As soon as you execute something that imports the package (which, you did install for a reason) the code can run.
I don't think that many people sandbox their development environments.
It absolutely matters. Many people install packages for front-end usage which would only be imported in the browser sandbox. Additionally, a package may be installed in a dev environment for inspection/testing before deciding whether to use it in production.
To me it's quite unexpected/scary that installing a package on my dev machine can execute arbitrary code before I ever have a chance to inspect the package to see whether I want to use it.
I've been using pnpm and it does not run lifecycle scripts by default. Asks for confirmation and creates a whitelist if you allow things. Might be the better default.
I think these compromises show that install hooks should be severely restricted.
Something like, only packages with attestations/signed releases and OIDC-only workflow should allow these scripts.
Worm could propogate through the code itself but I think it would be quite a bit less effective.
Most don’t need it. There was a time when most post installing flooded your terminal with annoying messages to upgrade, donate, say hi.
Modern node package managers such as yarn and pnpm allow you to prevent post installs entirely.
Today most of the time you need to make an exception for a package is when a module requires native compilation or download of a pre-built binary. This has become rare though.
My problem is that, in the JS ecosystem, every single time you go through a CI/CD pipeline, you redownload everything. We should only download the first time and with the versions that are known to work. When we make a manual update to version, than only that should be downloaded once more.
I just checked one of our repos right now and it has a 981 packages. It's not even realistic to vet the packages or to know which one is compromised. 99% of them are dependencies of dependencies. Where do we even get started?
Redownloading everything isn’t a risk when the lock file contains a hash of the download on first update.
Isn't that what lockfiles are for? By default `npm i` downloads exactly the versions specified in your lockfile, and only resolves the latest versions matching the ranges specified in package.json if no lockfile exists. But CI/CD pipelines should definitely be using `npm ci` instead, which will only install packages from a lockfile and throws an error if it doesn't exist.
That and pin that damn version!
It’s still ridiculous to me that version pinning isn’t the default for npm.
The first thing I do for all of my projects is adding a .npmrc with save-exact=true
save-exact is mostly useless against such attacks because it only works on direct dependencies.
Generate builder images and reuse them. It shaves minutes off each CI job with projects I'm working on and is non-optional because we're far from all major datacenters.
Or setup a caching proxy, whatever is easier for your org. I've had good experience with nexus previously, it's pretty heavy but very configurable, can introduce delays for new versions and check public vulnerability databases for you.
It's purely an efficiency problem though, nothing to do with security, which is covered by lock files.
NPM needs some kind of attestation mechanism. There needs to be an independent third party that that has the fingerprint, and then npm must verify it before a change is published. It could even be just DNS or well-known URI that, if changed, triggers lockdown. Then, even in the case of a successful compromise of an NPM account or source control, whether via phishing like the last one or token exfiltration like this one, it will remain unpublished.
Ironically I started seeing a message in GitHub saying 2fa will be auto-enforced shortly. Wonder if that is a sign of similar for npm packaging?
Or wonder if GitHub is enforcing 2fa soon because of the NPM CVEs potential to harvest GitHub creds?
2FA is the first steps is stopping the onslaught.
But it still doesn't stop infected developer machines to silently update code and wait for the next release patiently.
It would require the diligence of those developers to check every line of code that goes out with a release... which is a lot to ask for someone who fell for a fishing email.
Wow it got everything, aws keys, gcp keys, github tokens, thats a lot of cryptocoin mining instances that are going to be spun up. And a lot of unexpected bills people are going to be getting...
They really shouldn't have been stored unencrypted on peoples machines.... Ouch.
How many packages now have been compromised over the past couple of weeks? The velocity of these attacks are insane. Part of me believes state actors must be involved at this point.
In any case, does anyone have an exhaustive list of all recently compromised npm packages + versions across the recent attacks? We need to do an exhaustive scan after this news...
> Part of me believes state actors must be involved at this point.
Its less a technical but rather a moral hurdle. Its probably a bunch of teenagers behind it like how it was with the Mirai Botnet.
For those of you without a security dept, hopefully this is of some help: https://github.com/Cobenian/shai-hulud-detect
more updates soon and PRs welcome.
For a large subset of packages (like the browser ones), as a layman, it seems feasible to do static analysis for:
1) fetch calls
2) obfuscation (like sketchy lookup tables and hex string construction)
Like for (1) the hostname should be statically resolvable and immutable. So you can list the hostnames it fetches from as well.
Is this feasible or am I underestimating the difficulty? Javascript seems to have no shortage of static analysis tools.
There are many ways to "eval" in javascript, and static analysis can only work if that's also statically disallowed.
Unfortunately, eval is still used in a lot of code, so disabling it isn't trivially viable, and with eval present, detecting fetch calls and such statically becomes the halting problem.
Maybe stupid question here. And forgive my ignorance.
But does yarn or deno suffer from the same issues? That is do they get their packages from npm repositories? I've never used these.
Yes.
I haven't dug into the specifics but technical props and nostalgia to the "self propagating" nature. Reminds of the OG "Worm" - the https://en.wikipedia.org/wiki/Morris_worm
At this time should we just consider all of npm unsafe for installing new packages? Installing a single package could install hundreds of transient dependencies.
Yes. Also, no need for "at this time".
It's amazing how we attack normies for downloading random software but we will load our projects with hundred of dependencies we don't audit ourselves.
Just notice guys it did not started with tinycolor. I had first reported it here, I am just not as popular haha
My posts way before the issue was created: https://news.ycombinator.com/item?id=45252940 https://www.linkedin.com/posts/daniel-pereira-b17a27160_i-ne...
I guess it's still spreading? those blogs seem to list differences packages
Each one of these posts makes me feel better about having no dependencies on my current project, other than Gulp, which I could replace if I had to.
But also I miss having things like spare time, and sleep, so perhaps the tradeoff wasn't worth it
Perhaps set `minimumReleaseAge > 1440` in pnpm config until this is fixed.
I'm surprised this is happening now, and not 10 years ago.
We're seeing it now...
NPM gets a lot of traffic, there might be other package managers out there, in different languages, that may have been infected in the past and simply don't get the same amount of eyeballs.
The number of packages is now up to 180 (or more, depending on which source you're looking at)
Are Python packaging systems like pip exposed to the same risks?
Is anybody looking at this?
As much as I prefer Python over JavaScript, Python is vulnerable to this sort of attack. All it would take is a compromised update publishing only a source package, and hooking into any of setuptools's build or install steps. Pip's build isolation is only intended for reproducible builds. It's not intended to protect against malicious code.
PyPI's attestations do nothing to prevent this either. A package built from a compromised repository will be happily attested with malicious code. To my knowledge wheels are not required.
Not to the same extent as NPM. Because Python has a good standard library and library authors are not deathly afraid of code duplication like JS devs, for example micro libraries like left-pad, is-even etc.
The weird dig at JS as a community is wholly unnecessary. Python as an ecosystem is just as vulnerable to this crap - and they’ve had their own issues with it.
You can reference that and leave the color commentary at the door.
Unnecessary? Maybe if more people had commented on JS devs tendency to include every 3 line micro packages in existence we would not be in this situation.
Every ecosystem has this problem but NPM is the undisputed leader if you count all attacks.
Also there’s more of a habit to release to the pre release channel for some time first.
I honestly think a forced time spent in pre release (with some emergency break glass where community leaders manually review critical hotfixes) could mitigate 99% of the issues here. Linux packages have been around for ever and have fewer incidents mainly because of the long dev->release channel cooking time.
Forced time in pre-release sounds like a really good idea.
Can somebody drive this up the chain to people who administer npm?
Software supply chain attacks are well known and they are a massive hole in the entirety of software infrastructure. As usual with security, no one really cares that much.
Does anyone know when @ctrl/tinycolor 4.1.1 was released exactly? Trying to figure out the infection timeline relative to my tools.
Never mind, got it:
Would strict containerization help here? (rootless, read-only partial fs access, only the necessary env variables passed, etc)
Soon we'll see services like, havemysecretsbeenpwned.com check it against with your secrets xD given the malw seeks local creds.
To my experience 80% of companies do not care about their secrets will/being exposed.
There is this shallow belief that production will never be hacked
I wouldn't mind a simple touch id (or password) requirement every time I run `npm publish` to help prevent such an attack.
It's high time we took this seriously and required signing and 2FA on all publishes to NPM and NPM needs to start doing security scanning and tooling for this that they can charge organisations for.
As a developer, is there a way on mac to limit npm file access to the specific project? So that if you install a compromised package it cannot access any data outside of your project directory?
Wrote a small utility shell script that uses docker behind the scenes to prevent access to your host machine while still allowing full npm install and run workflow.
https://github.com/freakynit/simple-npm-sandbox
Disclaimer: I am not Docker expert. Please review the script (sandbox.js) and raise any potential issues or suggestions.
Thanks..
You can run nodejs through `sandbox-exec` which is part of macos.
I've never tried any of them but there's also a few wrappers specifically to do that, such as: https://github.com/berstend/node-safe
Otherwise you're down to docker or virtualisation or creating one system user per project...
Frankly, I am refusing to use npm outside of docker anymore.
Why did the socket.dev story from last night get flagged off the front page?
https://news.ycombinator.com/item?id=45256210
What indicates to you that it has been flagged?
npm considered harmful
I had just seen some guy on TikTok pushing `mcp-knowledge-graph` the other day
This blog post and others are from 'security saas' that also try to make money off how bad NPM package security safety is.
Why can't npm maintainers just implement something similar?
Maybe at least have a default setting (or an option) that packages newer than X days are never automatically installed unless forced? That would at least give time for people to review and notice if the package has been compromised.
Also, there really needs to be a standard library or at least a central community approved library of safe packages for all standard stuff.
This is a product of programming languages continuing to ignore the lessons from capability security. The fact that packages in your programming language even have the ability to any of the things listed in these articles by default is an embarrassing, abject failure of our profession.
Time for a Butlerian Jihad.
This seems like something that can be solved with reproducible builds and ensuring you only deploy from a CI system that verifies along the way.
In fact this blog post appears to be advertising for a system that secures build pipelines.
Google has written up some about their internal approach here: https://cloud.google.com/docs/security/binary-authorization-...
With repos and workflows being infected, wouldn't a CI-only deploy not help?
The malware is modifying files and adding github workflows. If your builds are reproducible and run from committed code then the only way to add the post install script is if the maintainer reviews and accepts the commit that adds it. Similarly with the github workflow branch.
And if your CI is building and releasing in a sandboxed hermetic environment, then the sandboxes that build and release don't need credentials like AWS_ACCESS_KEY because they can't depend on data from the network. You need credentials for deploying and signing, but they don't need to be present during build time.
> The malware is modifying files and adding github workflows. If your builds are reproducible and run from committed code
Exactly: it can simply commit its code and trigger a CI-only GitHub Actions deploy with no input from the maintainer at all.
Not from a the malicious branch.
By hypothesis the code only deploys from code committed to the main branch (or whatever the blessed branch for CI is). To create a GitHub Action that can deploy the code, the package maintainer must first manually approve and merge the malicious commit.
And the malware spreads by publishing new versions of NPM packages using credentials on the package owner's development machine. If the package owner didn't have credentials with publish access, this wouldn't spread like a worm. And if they had reproducible builds they wouldn't pull a new version of their dependencies from NPM at build time because they'd have to have pinned specific versions with specific hashes to get reproducibility.
Under these hypotheses it can spread, but only if the package owner manually pins a malicious version or manually approves a malicious commit.
At least they're not re-inventing the wheel though!!
Is there a theoretical framework that can prevent this from happening? Proof-carrying code?
Object-capability model / capability-based security.
Do not let code to have access to things it's not supposed to access.
It's actually that simple. If you implemented a function which formats a string, it should not have access to `readFile`, for example.
Retrofitting it into JS isn't possible, though, as language is way too dynamic - self-modifying code, reflection, etc, means there's no isolation between modules.
In a language which is less dynamic it might be as easy as making a white-list for imports.
People have tried this, but in practice it's quite hard to do because then you have to start treating individual functions as security boundaries - if you can't readFile, just find a function which does it for you.
The situation gets better in monadic environments (can't readFile without the IO monad, and you cant' call anything which would read it).
Well, to me it looks like people are unreasonably eager to use "pathologically dynamic" languages like JS & Python, and it's an impossible problem in a highly dynamic environment where you can just randomly traverse and change objects.
Programming languages which are "static" (or, basically, sane) you can identify all imports of a module/library, and, basically, ban anything which isn't "pure" part of stdlib.
If your module needs to work with files, it will receive an object which lets it to work with files.
A lot of programming languages implement object-capability model: https://en.m.wikipedia.org/wiki/Object-capability_model it doesn't seem to be hard at all. It's just programmers have preference for shittier languages, just like they prefer C which doesn't even have language-level array bound checking (for a lack of a "dynamic array" concept on a language level).
I think it's sort of orthogonal to "pure functional" / monadic: if you have unrestricted imports you can import some shit like unsafePerformIO, right? You have another level of control, of course (i.e. you just need to ban unsafePerformIO and look for unlicensed IO) but I don't feel like ocap requires Haskell
You can protect yourself using existing tools, but it's not trivial and requires serious custom work. Effectively you want minimal permissions and loud failures.
This is something I'm trying to polish for my system now, but the idea is: yarn (and bundler and others) needs to talk only to the repositories. That means yarn install is only allowed outbound connections to localhost running a proxy for packages. It can only write in tmp, its caches, and the current project's node_packages. It cannot read home files beyond specified ones (like .yarnrc). The alias to yarn strips the cloud credentials. All tokens used for installation are read-only. Then you have to do the same for the projects themselves.
On Linux, selinux can do this. On Mac, you have to fight a long battle with sandbox-exec, but it's kinda maybe working. (If it gained "allow exec with specified profile", it would be so much better)
But you may have guessed from the description so far - it's all very environment dependent, time sink-y, and often annoying. It will explode on issues though - try to touch ~/.aws/credentials for example and yarn will get killed and reported - which is exactly what we want.
But internally? The whole environment would have to be redone from scratch. Right now package installation will run any code it wants. It will compile extensions with gyp which is another way of custom code running. The whole system relies on arbitrary code execution and hopes it's secure. (It will never be) Capabilities are a fun idea, but would have to be seriously improved and scoped to work here.
Why yarn instead of pnpm?
It doesn't matter. It applies the same to all those tools.
Something similar to Deno's permission system, but operating at a package level instead of a process level.
When declaring dependencies, you'd also declare the permissions of those dependencies. So a package like `tinycolor` would never need network or disk access.
Yeah, LavaMoat (https://github.com/LavaMoat/LavaMoat). Dependencies are pinned with capabilities, and scripts are disabled by default.
Probably signatures could alleviate most of these issues, as each publish would require the author to actually sign the artifact, and setup properly with hardware keys, this sort of malware couldn't spread. The NPM CI tokens that don't require 2fa kind of makes it less useful though.
Clojars (run by volunteers AFAIK) been doing signatures since forever, not sure why it's so difficult for Microsoft to follow their own yearly proclamation of "security is our top concern".
I would like to see more usage of NPM/Github Actions provenance statements https://www.npmjs.com/package/sigstore#provenance through the ecosystem
> The NPM CI tokens that don't require 2fa kind of makes it less useful though
Use OIDC to publish packages instead of having tokens around that can be stolen or leaked https://docs.npmjs.com/trusted-publishers
Manual verification of releases and chain-of-trust systems help a lot. See for example https://lucumr.pocoo.org/2019/7/29/dependency-scaling/
There are, but they have huge performance or usability penalties.
Stuff like intents "this is a math library, it is not allowed to access the network or filesystem".
At a higher level, you have app sandboxing, like on phones or Apple/Windows store. Sandboxed desktop apps are quite hated by developers - my app should be allowed to do whatever the fuck it wants.
Do they actually have huge performance penalties in Javascript?
I would have thought it wouldn't be too hard to design a capability system in JS. I bet someone has done it already.
Of course, it's not going to be compatible with any existing JS libraries. That's the problem.
You can do that by screening module imports with zero runtime penalty.
I have been telling people for ages - Javascript is a pack of cards. We have progressed as a society and have so many alternatives for everything, and yet, we still haven't done anything about Javascript being forced down onto us by browsers. If it wasn't for web browsers, JS would have become irrelevant so fast because of how broken it is - both as a language and its ecosystem.
On the contrary - almost being a decade into Elixir - most of the time, I don't need (and I don't like) using external dependencies. I can just write something myself in a matter of just an hour or so because it's just so easy to do it myself. And everything I've written till date hasn't required an audit or re-write every 6 months or sometimes, even for years.
We all seem to hate the concept of Nazis and yet somehow we have done nothing about the Nazi-est language of them all which literally has no other alternatives to run on web browsers?
> It deliberately skips Windows systems
Reminds me of when I went to a tech conference with a Windows laptop and counted exactly two like me among the hundreds of attendees. I was embarrassed then but I'd be laughing now :D
..for now. Safer to assume there was a todo in the code and not some anti-Linux agenda.

Active NPM supply chain attack: Tinycolor and 40 Packages Compromised

(Additional context for Mr. Architect's Link Pasta: 33 comments, 1 day ago)
Unless npm infrastructure will be thoroughly curated and moderated, it always going to stay a high risk threat.
Need to stop using javascript on desktop ASAP. Also Rust might be a bit dangerous now?
Jesus Christ. Another one? What the fuck?
This isn't a JavaScript problem. What, structurally, stops the same thing happening to PyPI? Or the Rust ecosystem? Or Lisp via QuickLisp? Or CPAN?
This whole mess was foreseeable. So what's to be done?
Look. Any serious project needs to start vendoring its dependencies. People should establish big, coarse grained meta-distributions like C++ Boost that come from a trustable authority and that get updated infrequently enough that you can keep up with release notes.
> This isn't a JavaScript problem. What, structurally, stops the same thing happening to PyPI? Or the Rust ecosystem? Or Lisp via QuickLisp? Or CPAN?
For one, NPM has a really sprawling ecosystem where it's normal to have many dependencies.
I remember that I once tried to get started with angular, and I did an "init" for an empty project and "compile", and suddenly had half a gigabyte of code lying in my directory.
This means that there is a high number of dependencies that are potential targets for a supply chain attack.
I just took a look at our biggest JS/Typescript project at work, it comes in at > 1k (recursive) NPM dependencies. Our biggest Python project has 78 recursive dependencies. They are of comparable size in terms of lines of code and total development time.
Why? Differences in culture, as well as python coming with more "batteries included", so there's less need for small dependencies.
> For one, NPM has a really sprawling ecosystem where it's normal to have many dependencies.
Agreed, but it's a difference of degree (literally --- graph in- and out-degree) not kind.
> Or Lisp via QuickLisp
Common Lisp is not worth it - you are unlikely to hit any high-value production target, there are not many uses and they are tech-savy. Good for us, the 5 remaining users. Also, Quicklisp is not rolling-release, it is a snapshot done one or two times a year.
They were new versions of the packages instead of modified existing ones so vendoring has the same effect as the usual practice of pinning npm deps and using npm ci, I think.
Rust was hit by a similar attempt: https://github.com/rust-lang/crates.io/discussions/11889
Nothing much came of it, I don't know.
Is using any type of NPM type stuff a no go? Who reads the code and verifies is secure?
Other than the maintainer (which isn't of course guaranteed) no-one other than it being incumbent on userland deployment, and those deploying a lib into a project to review the code.
npm should be banned and illegal to work with.
The same could be said of quite a few equivalent in other programing languages.
New day, new npm malware. Sigh..
> New day, new npm malware. Sigh..
This. But the problem seems to go way deeper than npm or whatever package manager is used. I mean, why is anyone consuming a package like colors or tinycolors? Do projects really need to drag in a random dependency to handle these usecases?
So rather than focusing on how Microsoft/npm et al can prevent similar situations in the future, you chose to think about what relevance/importance each individual package has?
There will always be packages that for some people are "but why?" but for others are "thank god I don't have to deal with that myself". Sure, colors and whatnot are tiny packages we probably could do without, but what are you really suggesting here? Someone sits and reviews every published package and rejects it if the package doesn't fit your ideal?
You're partly right.
But the issue isn't just about the “thank god I don't have to deal with that myself” perspective. It's more about asking: do you actually need a dependency, or do you simply want it?
A lot of developers, especially newer ones, tend to blur that distinction. The result is an inflated dependency tree that unnecessarily increases the attack surface for malware.
The "ship fast at all costs" mindset that dominates many startups only makes this worse, since it encourages pulling in packages without much thought to long-term risk.
> So rather than focusing on how Microsoft/npm et al can prevent similar situations in the future, (...)
There's some ignorance in your comment. If you read up on debug & chalk supply chain attack, you'll end up discovering that the attacker gained control of the account through plain old phishing. Through a 2FA reset email, to boot.
What exactly do you expect the likes of Microsoft to do if users hand over their access to third parties? Do you want to fix issues or to pile onto the usual targets?

What leads you to believe React is not well suited to simple ecommerce sites?
1. It's a solution meant for highly interactive app-like websites, not static-content driven websites like ecommerces. React in this context is just the wrong tool for the problem that will give you a huge array of performance, bugs and ux problems.
2. Extensive ecommerce experience including Disney, Carnival Cruises, Booking, TUI, and some of the European leaders in real estate and professional home building tools among the others.
> 1. It's a solution meant for highly interactive app-like websites, not static-content driven websites like ecommerces. React in this context is just the wrong tool for the problem that will give you a huge array of performance, bugs and ux problems.
Strongly disagree. React is not about interactivity, but reactivity. If you have to consume an API and update your app based on the responses, React does all the heavy lifting for you without requiring full page reloads.
On top of that, and as a nice perk, React also gives you all the tools you will ever need to optimize perceived performance.
Claiming that a tool designed for reactive programming is not suited for the happy flow of reactive programming is simply fundamentally wrong.
1. React didn't invent SPAs and reactivity.
2. Ecommerces are not highly dynamic pages. They are overwhelmingly static content with an occasional configurator/cart/search. All things that can be embedded with whatever library you like (including React), or even better none at all.
3. Seo and performance is what really matters in ecommerces. The only minor exceptions are shops like Amazon or Airbnb, but that's unrelated to their seo and performance.
4. I've been writing React and ecommerces using React and similar with millions of daily users for a decade :)

My comment yesterday, which received one downvote and which I will repeat if/until they’re gone: HTTP and JS have to go. There are ways to replace them.
HTTP?
We have good protocols for sharing programs. HTTP was designed to share stylized documents which it’s OK at. The browser probably should have stuck to rendering and left the p2p file sharing to a better protocol. It absolutely is not fit for the problem domain its been shoehorned into nor does it need to serve that role.
I dont follow. Are you saying the web should be p2p not client server? Or there is something specifically bad about http?
One downvote is not enough.
One upvote is not enough. We need enough upvotes to fix the problem. You can’t shape a big pile of shit into success. HTTP and JS will never serve as a proper application framework.
Would you care to elaborate? What solution do you propose, and how would it be implemented? How would removal of JavaScript and HTTP solve the dependency malware issue being discussed?
