On June 11, someone going by the username arojas spent what was probably a quiet afternoon methodically adopting orphaned Arch User Repository packages and injecting them with malware. By the time the community caught on, 408 packages were already compromised. By the time this piece was being written, that number had crossed 900 and is still climbing.
Sonatype researchers have named the campaign Atomic Arch. It’s one of the largest AUR supply chain incidents on record, and the technical sophistication of the payload puts it well beyond your average package repository drive-by.
