Irvine, Calif., August 9, 2012  — Blizzard Entertainment, Inc. today notified its players that there was unauthorized access to some Battle.net account information.

The unauthorized access included email addresses associated with Battle.net accounts in all regions, outside of China. Additional information from accounts associated with the North American servers (which generally includes players from North America, Latin America, Australia, New Zealand, and Southeast Asia) was also accessed, including cryptographically scrambled versions of passwords (not actual passwords), the answer to a personal security question, and information relating to Mobile and Dial-In Authenticators. It’s important to note that at this time, Blizzard does not believe this information alone is enough to gain access to Battle.net accounts.

Based on Blizzard’s investigation to this point, credit card and other customer payment data does NOT appear to have been accessed or affected. As a precaution, however, Blizzard encourages players to change their Battle.net password and any similar passwords used for other purposes.

Upon discovery of the unauthorized access, Blizzard took quick action to close off the unauthorized access and notify appropriate law enforcement.  Investigations are ongoing and Blizzard continues to work with authorities and security experts.
