Update: Doug Lombardi, director of marketing for Steam, tells 1UP, "There has been no security breach of Steam ... The alleged hacker gained access to a third-party site that Valve uses to manage the commercial partners in its Cyber Cafe program. This Cyber Cafe billing system is not connected to Steam. We are working with law enforcement agencies on this matter, and encourage anyone with more information to e-mail us at Catch_A_Thief [at] ValveSoftware [dot] com."
