PKGBUILD

Supply Chain Attack Targets Arch Linux Community Repository

Arch Linux has temporarily suspended package adoptions in the Arch User Repository after detecting accounts taking over abandoned projects to insert malicious code. The platform later expanded the restriction by blocking all new submissions to the AUR to contain ongoing supply chain attacks. Attackers were adopting packages without active maintainers and introducing harmful changes through subsequent commits that could bypass user scrutiny due to established project history. Newly created packages containing malicious build commands, including requests for elevated privileges, were also discovered. Affected accounts have been banned and identified projects removed from the repository. The incident does not impact official Arch Linux repositories, with risk limited to community-maintained AUR packages that require manual review of PKGBUILD files before installation or updates.
