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

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.

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.)
