Battle.net Hack Attack Hits Millions
The account details of millions of players have been stolen in a hack attack on Blizzard, the maker of World of Warcraft, StarCraft and Diablo.
Blizzard revealed details of the breach in a message posted to its Battle.net account management service.
In an statement on its Battle.net account management service, Blizzard advised players in North America to change their login details for the account management service but that so far, there was no evidence that credit card numbers and other personal details had been taken.
In the statement, Blizzard's boss Mike Morhaime said it discovered on 4 August that there had been "unauthorized and illegal access" to its internal network.
The company's investigation into the breach revealed that whoever broke into the system obtained a list of all email addresses for Battle.net users outside of China.
The hackers also gained information about users' security questions and the account authenticators used by players on North American servers. As well as players in the US and Canada this includes people in Latin America, Australia, New Zealand, and Southeast Asia.
The hackers also stole a cryptographically scrambled list of the passwords used on North American Battle.net accounts. Morhaime assured users that the technique Blizzard used to conceal these passwords made it hard to unscramble them.
