408 AUR Packages Compromised via Spoofed Maintainer Injecting atomic-lockfile NPM Payload
A large-scale AUR supply-chain compromise injected infostealer and eBPF rootkit code into 408 packages through maintainer spoofing. Evidence from Socket.dev and GitHub linkage shows coordinated tooling reuse across incidents. Persistent registry verification gaps enable these attacks to scale beyond isolated cases.

Arch users must audit installed packages against the published list and rotate all credentials. Systems showing rootkit indicators require forensic preservation and reinstallation. Registry operators should implement signed maintainer attestations to prevent recurrence of spoofed adoption attacks.
⚡ Prediction
Arch Linux security team: at least 50 additional compromised packages will surface within 14 days once full maintainer audit completes.
