Arch contributors are cleaning up a malware incident in the AUR after suspicious updates appeared across several user-maintained packages.

Arch Linux’s AUR is experiencing a malware incident involving user-contributed packages with malicious commits that attempt to download npm-based payloads during installation. (…)

Arch users should not update AUR packages without review. Examine PKGBUILD diffs, check any new .install files, and be cautious if updates introduce npm commands or dependencies unrelated to the software.

Users who recently updated affected AUR packages should review package history, examine executed suspicious install scripts, and treat any unexpected npm-based installation behavior as a possible compromise.
