Hackers are infecting players of an old Call of Duty game with a worm that spreads automatically in online lobbies, according to two analyses of the malware.

On June 26, a user on a Steam forum alerted other players of Call of Duty: Modern Warfare 2 that hackers “attack using hacked lobbies,” and suggested running an antivirus. The malware mentioned in the thread appears to be on the malware online repository VirusTotal.
