Arch Linux disables AUR package adoption after malware attacks

A concrete supply-chain security case: community package repositories can be attacked through abandoned-package adoption, not only through new account abuse or compromised maintainers.

What it is: LWN news item on Arch Linux disabling adoption of orphaned AUR packages after another malware campaign.

Gist: Arch's DevOps team disabled orphaned-package adoption in the AUR after an influx of malicious package adoptions and follow-up commits. The linked analysis describes the payload as a Tor-controlled remote-access trojan that tries to upload a broad range of user data.

The important detail is the failure mode: the attacker path runs through abandoned community packages. Arch had already suspended new account registration in June after a similar campaign, then reopened registration in July with minor restrictions. This new round suggests that package-adoption workflow itself is part of the attack surface.

Newsletter angle: Useful supply-chain security case study for community package repositories: abandoned-package takeover is a governance and workflow problem, not just a malware-detection problem.
