Shai-Hulud malware attack: Tinycolor and over 40 NPM packages compromised

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.

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).

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.

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.
