Battle.net, the gaming service provided by Blizzard that powers World of Warcraft, StarCraft II and Diablo III, has been compromised resulting in loss of customer data.
Blizzard’s president Mike Morhaime confirmed the hack tonight through a security update posted on the Blizzard website.
“Even when you are in the business of fun, not every week ends up being fun. This week, our security team found an unauthorized and illegal access into our internal network here at Blizzard. We quickly took steps to close off this access and began working with law enforcement and security experts to investigate what happened.”
At this time, we’ve found no evidence that financial information such as credit cards, billing addresses, or real names were compromised. Our investigation is ongoing, but so far nothing suggests that these pieces of information have been accessed.
Morhaime went on to say that Email addresses for global Battle.net users outside of China have been illegally acquired. Users are urged to change their passwords. A mandatory change will be introduced soon.
