Epic Games has temporarily shut down some of its user forums for maintenance after data on 808,000 accounts was stolen. The compromise involved several forums maintained by Epic Games, based in Cary, N.C., that center on games and developer tools. The most affected forums are Infinity Blade, UDK, Gears of War archives and those for previous Unreal Tournament games. Email addresses and data entered into forums were leaked, but not password-related data. The hacker who stole the data exploited a vulnerability in the popular vBulletin forum software.”]
