Millions of gamers have been affected by a successful hack according to Blizzard Entertainment who today issued an apology to all its customers via the Blizzard website (see here).
A range of popular online multiplayer games are facilitated at Blizzard.net including World of Warcraft, Starcraft and Diablo.
According to Blizzard Entertainment they are aware that cryptographically scrambled passwords and other sensitive details including email addresses, personal security questions, and details relating to mobile and dial in authenticators were illegally accessed.
Although Blizzard believe the passwords are strongly enough protected they're recommending that all users of North American servers change their passwords and will be prompting users to change their security questions via an automated service. Email data relating to global users has however also been compromised.
Blizzard's security update announcement is available here and they've added an online FAQ for affected users here.
