Blizzard’s issued a security announcement on Battle.net – the interconnected network that powers its Starcraft, Diablo, and Warcraft family of titles – stating that an intrusion has been identified by the company’s security team.

Currently, there’s no evidence to suggest that “financial information such as credit cards, billing addresses, or real names were compromised.” A list of email addresses for Battle.net users was accessed in all regions apart from China. Additionally, for North American accounts, the personal security question was accessed, along with information relating to Mobile and Dial-In Authenticators.

The breach also exposed “cryptographically scrambled versions of Battle.net passwords (not actual passwords) for players on North American servers.” The company is recommending that users change their password on Battle.net now as a precaution.

For those on North American servers, Blizzard says it will force a reset of all secret questions and answers through an automated process in the coming days. Mobile authenticator users will also be prompted to update their authenticator software.

The full statement is over on Blizzard’s site.
