I hope all the Arch based distros will do a proper post to inform their users on how to cleanup afterwards.
I’m hoping at least cachyos, the distro I use, will tell me exactly how to check and clean my system.
I remember that when I installed a few of my AUR package, I was well aware that this repo was pretty much unregulated and that I just have to trust it’s safe. So I made sure to only use AUR as a last resort. But there was warnings on cachyos that were displayed to tell me to be cautious about it so that’s at least a positive.
The article has instructions to do exactly that.
Users who regularly install AUR packages should take the following steps immediately:
Run pacman -Qm to list all foreign (AUR) packages installed on your system and cross-reference against the published list of compromised packages
Audit recent PKGBUILD history for any packages installed between June 10–12, 2026
Rotate all credentials — browser passwords, SSH keys, API tokens, and cloud access keys — if any flagged package was installed
Scan for suspicious processes masquerading as kernel threads using tools like rkhunter or chkrootkit
Consider using AUR helpers with PKGBUILD review prompts enabled by default.
