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.

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.

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.

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.

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.

"What are the actual guarantees that <guy leaving his keys on his dashboard> make that <guy leaving his keys on an illuminated blinking sign outside his house> don't make?"

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.

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.

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 or how 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.
