A message on Blizzard’s site by none other than Mike Morhaime has stated that there was “an unauthorized and illegal access into our internal network”, with various pieces of data being illegally accessed. However, there is so far no evidence that any financial or personal information was compromised.
The statement mentions that Battle.net e-mail addresses outside of China were accessed, and that players on North American servers (which also include players in Latin America, Australia, New Zealand and Southeast Asia) answers to personal security questions and mobile and dial-in authenticator details were also accessed.
While the passwords are encrypted, Battle.net users on North American servers have been advised to change their passwords. Blizzard will also be prompting users to change their secret question and answers and update their mobile authenticator software.
