This is presumably because libc just doesn't change very often (not meaning code changes, but release cadence). But the average native software stack does have lots of things that change relatively often[1]. So "native" vs. not is probably not a salient factor.

Ie if you weren’t running dev distros in prod, you probably weren’t exposed.
Honestly a lot of packaging is coming back around to “maybe we shouldn’t immediately use newly released stuff” by delaying their use of new versions. It starts to look an awful lot like apt/yum/dnf/etc.
I would wager in the near future we’ll have another revelation that having 10,000 dependencies is a bad thing because of supply chain attacks.
This is the security equivalent of having a better lock than your neighbour. Won't save you in the end but you won't be first. Then again, yours could also be broken and you don't get to tick of that audit checkbox.
your link disproves your claim. no naive app depended on xz version >= latest. Most sane distros take time to up-rev. That is why the xz backdoor was, in fact, in NO stable distro
I don't think it does; I think the industry opinion on xz is that we got lucky in terms of early detection, and that we shouldn't depend on luck.
(I don't know what a "sane" distro is; empirically lots of distros are bleeding-edge, so we need to think about these things regardless of value judgements.)
From experience, a lot of people using a "stable" distro are just bypassing that distro's stability (read: staleness) by installing nightly things from a language ecosystem. It's not clear to me that this is a better (or worse) outcome than a less stable distro.
Native software? You mean software without dependencies? Because I don't see how you solve the supply chain risk as long as you use dependencies. Sure, minimizing the number of dependencies and using mostly stable dependencies also minimizes the risk, but you'll pay for it with glacial development velocity.
> Do you think supply chain attacks will just get worse? I'm thinking that defensive measures will get better rapidly (especially after this hack)
I think the attacks will get worse and more frequent -- ML tools enable doing it easily among people who were previously not competent enough to pull it off but now can. There is no stomach for the proper defensive measures among the community for either python or javascript. Why am i so sure? This is not the first, second, third, or fourth time this has happened. Nothing changed.
Not only do the tools enable incompetent attackers, they also enable a new class of incompetent library developers to create and publish packages, and a new class of incompetent application developers to install packages without even knowing what packages are being used in the code they aren't reading, and a new class of incompetent users who are allowing OpenClaw to run completely arbitrary code on their machines with no oversight. We are seeing only the tip of the iceberg of the security breaches that are to come.
So basically the attacker and the dev who caught it were probably using the same tools if the malware was AI-generated (hence the fork bomb bug), and the investigation was AI-assisted (hence the speed). Less "tip of the iceberg" and more just that both sides got faster.
