Sorry for hijacking threads like this again, and I know people have opinions about cooldowns etc. but cooldowns would save you from axios, tanstack, and many other recent npm supply chain attacks. If you work in a large company, you already likely have cooldowns via Artifactory / Nexus, and if you don't, it's easy to set up.
Why cooldowns? Most npm (or pypi) compromises were taken down within hours, cooldowns simply mean - ignore any package with release date younger than N days (1 day can work, 3 days is ok, 7 days is a bit of an overkill but works too)
- or if you want a one click fix, use https://depsguard.com (cli that adds cooldowns + other recommended settings to npm, pnpm, yarn, bun, uv, dependabot and renovabot)
- or use https://cooldowns.dev which is more focused on, well, cooldowns, with also a script to help set it up locally
All are open source / free.
If you know how to edit your ~/.npmrc etc, you don't really need any of them, but if you have a loved one who just needs a one click fix, these can likely save them from the next attack.
Caveat - if you need to patch a new critical CVE, you need to bypass the cooldown, but each of them have a way to do so. In the past few weeks, while I don't have hard numbers, it seems more risk has come from Software Supply Chain attacks (malicious versions pushed) than from new zero day CVEs (even in the age of Mythos driven vulnerability discovery)
What are the actual guarantees that go/Rust make that Python/npm don’t? It seems like it might just be that Python/npm are juicier targets? I’m starting to try and avoid all third party packages
It is 100% up to the package manager's steward to control how ownership of packages and namespaces are granted.
Maven Central exists for decades the amount of incidents of people stealing namespaces is minimal.
One can't simply publish a package under the groupId "com.ycombinator" without having some way to verify that they own the domain ycombinator.com. Then, once a package is published, it is 100% immutable, even if it has malicious code in it. Certainly, that library is flagged everywhere as vulnerable.
It baffles me that NPM for so long couldn't replicate the same guardrails as Maven Central.
> It seems like it might just be that Python/npm are juicier targets?
Attackers go where the victims are. Frontend is a monoculture with the vast majority using NPM; backend, less so. This isn't an excuse for NPM, but another strike against it.
You could also argue that the attacks make a deeper point about frontend vs backend devs, but I won't go there.
There is build.rs, proc macros are unsandboxed, and lastly you install the binary so that you can run it. Even if the build and install were fully sandboxed, the binary could still do malicious stuff if ran.
It has build.rs that will run as soon as you compile the dependency. That's not the same thing but pretty close to a post install script: it's very likely to run.
Part of the point the article makes is that most other popular languages have a comprehensive standard library. JS has an astonishingly small on. Rather than have one vetted set of libraries that ship with the language, applications either need to roll it themselves or pull from a 3rd party package repository. We've drilled NIH into people, so they tend to reach for packages. That's not necessarily a bad thing, but it often means they're pulling in more code than they need. The JS ecosystem has also favored smaller modules, so you need many of them. And everyone builds on top of that, leading to massive growth in dependency graphs. It's a huge surface area for things to go wrong, intentionally or not.
With many other languages, you have a lot of functionality out of the box. Certainly, there have been bugs and security issues, but they're a drop in the bucket compared to what you see in the JS ecosystem. With other languages, you have a much smaller external dependency graph and the core functionality is coming from a trusted 3rd party.
What important functionality do you feel is missing from the commonly used JS environments (node and browser) that is causing people to install it as a third party dependency?
The issue isn’t that the functionality doesn’t exist, it’s always backwards compatibility with versions where it did not yet exist.
I'm not convinced that Python should be the standard for package management either. Earlier this week I was trying to publish a Python package for the first time wrapping a Rust library I wrote (for use only on Linux and Python 3.12+), and it literally took me hours to get from "I have a wheel that I can import and it works on my system" to "I have published that wheel and can install the package from PyPI on the set of systems that I'm trying to support and it actually works". Everything I've heard about this indicates that the situation for Python packaging is literally better than it ever has been before with the current tooling, so I can't even imagine how bad it was for the decades before. In comparison, having literally never touched npm before, I was able to publish a wrapper around the same library and validate that it was working in maybe 10 minutes (most of which were spent from not realizing that a certain tool was failing with a vague "file not found" error because I hadn't installed npm yet).
I'm not saying that npm is doing everything right, but I suspect that beyond the obvious low-hanging fruit that we hear about pretty consistently with npm there's probably a long tail of less obvious stuff that can be exploited that will not be specific to npm. The fundamental problems with supply-chain vulnerabilities aren't going to go away if npm magically became pip or go modules overnight.
I suppose that go's go:generate workflow can also be abused to land a worm like the ones spreading via npm, as you can build programs that just scrape the whole hard drive for git projects and patch the go.mod dependencies there, and you could also just write this in go as a toolchain script, for example.
NPM's achilles is the pre/postinstall step which can run arbitrary commands and shell scripts without the user having any way to intervene.
Dependencies must be run in isolated chroot sandboxes or better, inside containers. That would be the only way to mitigate this problem, as the filesystem of the operating system must be separated from the filesystem of the development workflow.
On top of that most host based firewalls are per-binary instead of per-cmdline. That leads to the warnings and rules relying on that e.g. "python" or "nodejs" getting network access allowlisted, instead of say "nodejs myworm.js". So firewalls in general are pretty useless against this type of malware.
Note that the NPM worms are spreading because the package providers are developing on their libraries without them noticing a malicious dependency. It is not users/consumers spreading the worm, it is developers spreading it.
Your mismatch is that you think in policies, not assessments here. Nothing in my normal go workflow will ask me if I want to run "curl download whatever from the internet" when I run go build.
Though I agree with the difference in workflow, there is not a single mechanism in go catching this. go.mod files can be just patched by the worm, and/or hidden behind a /v123 folder or whatever to play shenanigans on API differences.
Generally, other package managers aren't great either. Notably, crates.io / cargo has some of the same issues as NPM and the verbiage of their excuses for not fixing these problems is oddly similar.
Something fascinating about the design and architecture of programming languages and their surrounding ecosystems is the enormous leverage that they provide to the "core team":
For every 1 core language developer[1]...
... there may be 1,000 popular package developers...
... for which there may be 1,000,000 developers writing software...
... for over 1,000,000,000 users.
This means that for every corner that is cut at the top of that pyramid, the harms are massively magnified at the lower tiers. A security vulnerability in a "top one thousand" package like log4j can cause billions of dollars in economic damage, man-centuries of remediation effort, etc.
However, bizarrely, the funding at the top two levels is essentially a pittance! Most such projects are charities, begging for spare change with hat in hand on a street corner. Some of the most used libraries are often volunteer efforts, despite powering global e-commerce! cough-OpenSSL-cough.
The result is that the people most empowered to fix the issues are the least funded to do so.
This is why NPM, Crates.io, etc... flatly refuse to do even the most basic security checks like adding namespaces and verifying the identity of major publishers like Google, Microsoft, and the like.
That's a non-zero amount of effort, and no matter how trivial to implement technically and now cheap to police, it would likely blow their tiny budget of unreliable donations.
The exceptions to this rule are package-managers with robust financial backing, such as NuGet, which gets reliable funding from Microsoft and supports their internal (for-profit!) workflows almost as much as it does external "free" users.
"Free and open" is wonderful and all, but you get what you pay for.
[1] Most of us can name them off the top of our heads: Guido van Rossum, Larry Wall, Kerningham & Richie, etc.
There has been a lot of pain at my various jobs installing a safe global npm config on every developer machine, asking people not to disable it, checking it with mdm tools. A safer out-of-the-box configuration is long overdue.
It's a cultural issue, always feeling the urge to update to the newest possible package for things that are already working fine, without even reading the changelog to see if it's applicable. Cooldowns are only a way to force a bit of patience onto the maintainers... and they work.
There is no legitimate reason why postinstall scripts need to exist. The npm team needs to grow up and declare "starting with npm version whatever, npm will only run postinstall scripts for versions of packages published before ${today}".
I audited several postinstall scripts recently in popular packages. They seem to be mostly around using native binaries, downloading them, detecting if the platform is compatible, linking to it directly instead of having it bootstrapped by node, working around issues in older versions of npm, etc. Since dev toolchains (e.g. esbuild) are now being built in compiled languages and distributed as binaries via npm registry. If you are on a recent version of node/npm and a common/recent OS/platform, you should be able to disable all the postinstall scripts without legitimate issue.
install scripts are a distraction, just like package signatures are a distraction. adding/removing either feature has no significant impact on the wormability of this package ecosystem. installed npm code is run, with nearly zero exceptions.
The installed code may be run in different settings, under a different user, with different privileges. Say, it may not run in CI/CD at all, or run only with the test user's privileges.
Postinstall scripts run at install time, with installer's privileges.
This doesn't really fix the issue though because package code is also executed at build time and during testing. Just maybe restricts the scope a little bit.
With respect, post-install scripts are a total red herring. You're alarmed by them because they are code controlled by someone else that runs on your box, and they could do something bad -- yes, they are, and yes they could.
But so is the regular code in those packages! It won't run at install time, but something in there will run -- otherwise it wouldn't have been included in the dependencies.
Thinking that eliminating post-install scripts will have more than a momentary impact on exploitation rates is a sign of not thinking the issue through. Unfortunately the issue is much more nuanced than TFA implies -- it's not at all a case of "Let's just stop putting the wings-fall-off button next to the light switch", it's that the thing we want to prevent (other people's bad code running on our box) cannot be distinguished from the thing we want (other people's good code running on our box) without a whole lot of painstaking manual effort, and avoiding painstaking manual effort is the only reason we even consider running other people's code in the first place.
I use C++ and Conan with my iwn recipes and pre-built artifacts.
This mitigates things to a great extent.
I do not know who thought that having your dependencies depend on the internet with a zillion users doing stuff to each package was a good idea for enterprise environments...
It is crazy how much things can get endangered this way.
No surprise here. That's what you get when you have a language/ecosystem where core devs refuse to fix fundamental flaws, cuz for them breaking backwards compatibility is the worse crime that can ever be committed. And so all that happens in JS-land will eternally be layering lipstick on the pig in the cesspool. Too afraid of going through something similar to the Python 2 -> 3 fiasco, I guess because too many web devs and site admins would be incensed at being forced to fix their broken universe; as if it isn't already broken in its current condition.
The answer is LLM inspection. Which, sadly, raises the cost of software, especially once evil LLMs start hiding the backdoors better. Long term the answer should be CHERI, in my opinion.

A good part of it is already implemented in web crypto, which is supported by browsers and node. There is a chance that npm could implement something there without extra dependencies. Maybe I'm too optimistic?
Would that help? Most of these recent attacks, the attackers have gained access to the system that builds the packages. So it would have just signed the malicious build the same.
nope, doesn't help. signatures and removal of script points have zero net effect on the value of the target that the ecosystem has, or how easy/hard it is to write a worm. the package code gets run, this is statistically true, and the exploited developers/environments will sign packages, this is also statistically true.
Probably the same reason that pretty much no other package manager (or even major email provider, when email is ostensibly the most famous use-case for it) has adopted it: the UX is atrocious.
subtree is better for this case, you want to encourage actual reading before running. reading won't catch everything but it catches a lot, and the burden isn't as high as people always complain about before they try it.

To be honest Rust has the exact same supply chain attack pattern - it's just newer and more maintained at the moment. Give it a decade.

Why Python, tho, in that case? Its stdlib is quite robust. Surprisingly so in some areas.

The fundamental problems with supply-chain vulnerabilities aren't going to go away if npm magically became pip or go modules overnight.
Last I checked npm had 2FA for publishing, but cargo didn't. I don't think cargo is any better than npm, just not that of an attractive target.
I suppose that go's go:generate workflow can also be abused to land a worm like the ones spreading via npm, as you can build programs that just scrape the whole hard drive for git projects and patch the go.mod dependencies there, and you could also just write this in go as a toolchain script, for example.

`go:generate` is for the package provider, the command never runs when someone `go install` or `go get` the package.
Note that the NPM worms are spreading because the package providers are developing on their libraries without them noticing a malicious dependency. It is not users/consumers spreading the worm, it is developers spreading it.

go:generate is done at dev time, not at build time.
Actually bindings are usually generated like that, at build time (though with a build cache that nobody knows how it corrupts all the time).
Examples that come to mind: webview/webview, webkit, cilium/ebpf and most other CGo projects that I have seen.
none. they just have smaller target populations.
Generally, other package managers aren't great either. Notably, crates.io / cargo has some of the same issues as NPM and the verbiage of their excuses for not fixing these problems is oddly similar.

Just dont use npm. Use a package manager which doesn't execute postinstall by default. The switch is incredibly simple.
Which package manager is that, and what caveats does it offer?
Pnpm - installs are faster to boot. We haven’t missed anything
pnpm
It's a cultural issue, always feeling the urge to update to the newest possible package for things that are already working fine, without even reading the changelog to see if it's applicable. Cooldowns are only a way to force a bit of patience onto the maintainers... and they work.

A lot of it ends up bundled to run in a browser though, and doesn't end up running in Node.js
Surely every layer of defense in depth is a distraction except the one that prevents the problem.
There is also not too much legitimacy to the fact that Rust packages can run unsandboxed when they build themselves.
I feel like it's harder to hide malicious stuff in Rust build scripts.
This doesn't really fix the issue though because package code is also executed at build time and during testing. Just maybe restricts the scope a little bit.
If you look at the last N npm worms, they all used postinstall scripts.
Is that even true?
shai-hulud and variants
https://www.stepsecurity.io/blog/mini-shai-hulud-is-back-a-s...
So N=1? 2? 3?
at least 3 that i can remember off the top my head in these last couple months. If you look further back you will find more.
Security issues aside, they are a nightmare in enterprise environments where internet and OS access is heavily restricted.
...and only if you invoke it with --dangerously-run-postinstall-scripts; otherwise it will report an error if a postinstall script is found.
This is definitely going to affect any packages that need to link to native code and/or compile shims, but these are very few.

Thoughts and Prayers to those affected
With the recent high-profile attacks on PyPI packages, it’s no longer true that npm is the “only package manager where this regularly happens”.
In fact, pip is much more dangerous than npm because it lacks a lockfile. uv fixes that, but adoption is proceeding at a snail’s pace.
UV adoption is happening, though. NPM is still the only name in town.
Huh ? uv is a package manager not a registry.
In JS world there is plenty of competition for package managers pnpm/ yarn/ burn all viable alternatives to npm the package manager.
Public registries for languages tend to coalesce around one service . Nobody wants to publish their library to 4 different registries .
Apparently it does now: https://packaging.python.org/en/latest/specifications/pylock...
https://pip.pypa.io/en/stable/cli/pip_lock/
But who cares about pip, uv is here.
I don't know about snails, but everything I'm in contact with has moved over to uv, and I can't imagine I'm the only one.
No surprise here. That's what you get when you have a language/ecosystem where core devs refuse to fix fundamental flaws, cuz for them breaking backwards compatibility is the worse crime that can ever be committed. And so all that happens in JS-land will eternally be layering lipstick on the pig in the cesspool. Too afraid of going through something similar to the Python 2 -> 3 fiasco, I guess because too many web devs and site admins would be incensed at being forced to fix their broken universe; as if it isn't already broken in its current condition.
The answer is LLM inspection. Which, sadly, raises the cost of software, especially once evil LLMs start hiding the backdoors better. Long term the answer should be CHERI, in my opinion.
I really don't understand why the npm project cannot embrace PGP as an ambulatory 'good enough' solution.
The NIH mentality in the ecosystem would result in a JavaScript pgp library which itself would be an npm package and subject to supply chain attacks. lol.
A good part of it is already implemented in web crypto, which is supported by browsers and node. There is a chance that npm could implement something there without extra dependencies. Maybe I'm too optimistic?
Would that help? Most of these recent attacks, the attackers have gained access to the system that builds the packages. So it would have just signed the malicious build the same.
nope, doesn't help. signatures and removal of script points have zero net effect on the value of the target that the ecosystem has, or how easy/hard it is to write a worm. the package code gets run, this is statistically true, and the exploited developers/environments will sign packages, this is also statistically true.
Probably the same reason that pretty much no other package manager (or even major email provider, when email is ostensibly the most famous use-case for it) has adopted it: the UX is atrocious.
These satire articles on cybersecurity are really entertaining.
The other one a few days ago was also good: https://nesbitt.io/2026/02/03/incident-report-cve-2024-yikes...
Vendorizing using git submodule should be a robust mitigation for this problem.
This feels like the modern analog of the king, the mice, and the cheese. What cats do I need to bring in to eat my git submodules?
subtree is better for this case, you want to encourage actual reading before running. reading won't catch everything but it catches a lot, and the burden isn't as high as people always complain about before they try it.
