Blizzard have released a security update that reveals a breach of their internet network was carried out this week. They state that at this time 'we’ve found no evidence that financial information such as credit cards, billing addresses, or real names were compromised.' However their investigation with law enforcement and security experts is still ongoing.
Blizzard have confirmed that some data has been accessed, including e-mail addresses for users outside of China, as well as answers to security questions for North American server users. In addition to information relating to 'Mobile and D
ial-In Authenticators'. Blizzard believe based on their current information that 'this information alone is NOT enough for anyone to gain access to Battle.net accounts.'
Cryptographically scrambled versions of Battle.net passwords of North American server users were also accessed but Blizzard claims their Secure Remote Password protocol makes it very difficult for the real passwords to be cracked. Users have still been advised to change their Battle.net passwords and also any other accounts that use the same password.
Mike Morhaim, Blizzard's president and co-founder expressed his apologies, ending the article by saying 'We take the security of your personal information very seriously, and we are truly sorry that this has happened.'
