Was the U.S. military drone virus caused by pilots playing Mafia Wars?

The malware that infected unmanned aerial drones in the US Air Force “is routinely used to steal log-in and password data from people who gamble or play games like Mafia Wars online,” notes the Associated Press, citing an anonymous defense official.

"That official did not explain why drone crews were playing Mafia Wars or similar games during their overseas missions," observes Noah Shachtman at Danger Room, who first broke the pwned drone story.
