A massive supply chain attack targeting the Arch User Repository (AUR) has compromised more than 400 community-maintained packages, with attackers injecting malicious build scripts designed to deploy credential-stealing malware and rootkit-style payloads on affected Linux systems.
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).
