The “Atomic Arch” campaign compromised over 1,500 AUR packages between June 10-12, targeting SSH keys and API tokens. If you updated via yay or paru during that window, you need to audit your local system.
I’ve built a client-side tool to help with this.
Local Processing: Your package list never leaves your browser. All comparisons are done client-side.
Live Data: It fetches the verified malicious list directly from the official Arch servers (md.archlinux.org) to ensure it’s always current. Zero Bloat: No trackers, no ads, no cookies. How to use:
- Run pacman -Qm
- Paste the output into the tool
In example if you don’t use the AUR at all, or the packages you installed are not affected. In example the packages from the AUR I have installed have no such changes that could affect me from this malicious attack. Also if the packages you have are not updated in the last couple of days (or weeks) and are not even orphaned packages, then it is unlikely that you are affected by this attack. I am not talking of specific packages only, but a systematic logic you can follow.
The script https://github.com/lenucksi/aur-malware-check does a good job and not just check for known infected packages.
