The XZ utils backdoor made it into Debian repositories undetected, although it was caught before it was in a stable version.
Debian repositories are quite secure, but also pretty limited in scope and extremely slow to update. In practice, basically everyone (I'm sure there are a few counterexamples) using a Linux distro uses it as a base and runs extra software from less tightly controlled sources: Docker hub, PyPI, npm, crates, Flathub etc. It's far easier for attackers to target those, but their openness also means there's a lot of useful stuff there that's not in Debian.
Holding up Debian as a model for security is one step up from the old joke about securing your computer by turning it off and unplugging it. It's true, but it's not really interesting.
- fsflover 6mo agoXZ attack is an extremely rare event coming likely from a state actor, which actually proves that GNU/Linux is a very important target. It was also caught not least thanks to the open nature of the repository. Also, AFAIK it wasn't even a change in the repo itself. In short, using FLOSS is the way to ensure security. Whenever you touch proprietary staff, be careful and use compartmentalization.
