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.

The Checklist of infected packages

Ok, but I was expecting something a bit more automated then opening a list of package in kate and comparing it to my list of installed AUR package... Plus it's 400 package so that's a lot of things to check and plenty of space to miss one package by manually checking.

But I get it I'm lazy and just need to script something myself. This is affecting so many people I thought we would have a script to check quickly if you are "infected".

Edit : thanks for the numerous script sent as reply ! But I'm all set now, thanks !

how many aur packages do you have? Most people i know have like AT MOST 20 or so packages from the aur. Which takes less then 2 mins to manually check against the list.

[–] Tetsuo@jlai.lu 0 points 2 months ago (1 children)

I'm not home for a few days so I can't check yet.

But I think I have something like 3/4 packages at the most.

But I need to compare that to a 400+ list I'm not sure I agree with you it's that easy to do rigorously.

Not sure I understand - if you only have 3-4 packages you can just search for them specifically in the long list?

Even if you have 50 or 100s of packages, bash makes it pretty doable

comm -12 <(sort -u file1.txt) <(sort -u file2.txt) > common.txt

Should spit out only the packages appearing in both lists (done by memory so may not be 100%)

Do you have anything that will wipe their butt too?

[–] 0x0@infosec.pub -1 points 2 months ago

You could probably find it on aur lmao
