Battle.net has been compromised by hackers, Blizzard Entertainment president Mike Morhaime confirms in an update on the company's official website. Financial information -- including real names, billing addresses, and credit card numbers -- appears to be safe, but the hackers managed to access a list of email addresses, personal security questions, and "information relating to Mobile and Dial-In Authenticators." Also obtained was a list of "cryptographically scrambled" Battle.net passwords.
Morhaime goes on to state that the stolen information "is NOT enough for anyone to gain access to Battle.net accounts," though that doesn't mean you shouldn't take precautions. The hacking affects users "outside of China," and Morhaime recommends that anyone using the North Amercan servers -- "which generally includes players from North America, Latin America, Australia, New Zealand, and Southeast Asia" -- change their passwords.
In the days ahead, all Battle.net users on the North American servers will be asked to change their secret questions. In addition, Blizzard will be issuing an update to its authenticator software, which, for your own sake, is hopefully something that you already use.
