In a recent message posted to its Battle. net account management service, bigwig game developer Blizzard Entertainment has confirmed that the personal data of millions of users has been exposed in a Battle. net hack attack.

Disclosing the details of the data breach, Mike Morhaime – the President of Blizzard - said in a message to the users that the data which has been stolen in the attack apparently includes email addresses and scraps of Battle. net log-in details. Morhaime said that the information exposed in the breach seemingly does not include the users’ real names, their billing address, and their credit card numbers.

Acknowledging that hackers managed to illegally access some of Blizzard users’ personal information, Morhaime said that the data breach included “a list of email addresses for global Battle. net users, outside of China."

Further adding that the hackers had also accessed the answer to the personal security question of players on North American servers, as well as details pertaining to Mobile and Dial-In Authenticators, Morhaime however asserted: “Based on what we currently know, this information alone is NOT enough for anyone to gain access to Battle. net accounts."

Despite the fact that there still is no clarity about the exact nature of the attack and its timing, Morhaime said that the users who have been affected by the breach chiefly include North Americans players; though players in Latin America, Australia, New Zealand, and Southeast Asia have also probably been affected.
