Chaotic is not just as problematic, thankfully. They have systems in place to flag suspicious changes for human review before letting them out and it has, so far, prevented them from shipping any compromised updates.
I thankfully hadn't updated anything from the AUR for a couple of months (it doesn't happen by default when I update the rest of my system) and was unaffected, and after looking at the list of things I had from the AUR, I didn't need any of them... So I now have zero AUR packages on either of my systems.
Ironic, given the name.
I'm very new to Arch so I'm still confused as to where I stand. Hopefully I haven't been pwned. Sadly, my distro includes AUR packages by default.
My distro (Garuda) included a couple back when I originally installed it, but doesn't use them currently (namely wine-nine - which was affected) but the built-in system update didn't touch AUR unless you explicitly tell it to, so that saved my bacon in this situation (my AUR packages hadn't been updated in 2 months).
How do I check to see if that's the case for me too?
As I showed above, I also had wine-nine, but I can't tell if that log is listing all the times wine-nine was updated or all the times I updated with wine-nine installed.
I'm leaning toward the latter given it was just listing
wine-nine 0.10-1repeatedly, implying it never updated past that in the dangerous period, right?I am not at home (and work is stuck on windows) so I can't verify with 100% certainty... But I believe what I did was pacman -Qm to list the AUR packages. Then I did pacman -Qi <package_name> to list the details about why it was installed, what dependencies it has, what depends on it, and when it was last updated. Mine showed like 2 years prior (whenever I installed the OS) because there hadn't been any update to it in years (until the attack). If your date for last updated is recently, you probably have a problem.
