World of Warcraft-maker Blizzard has become the latest victim of a security breach.
Blizzard CEO Mike Morhaime broke the news yesterday in a security update to users.
Credit card information, billing addresses or real names were not compromised, Morhaime asserts.
The data that was stolen included a list of email addresses for global Battle.net users outside of China.
The answer to the personal security question, and information relating to mobile and dial-in authenticators were also accessed for players on North American servers – which generally includes players from North America, Latin America, Australia, New Zealand and South-East Asia.
Blizzard claims that this information alone is “not enough for anyone to gain access to Battle.net accounts”.
However, it has recommended that players on North American servers change their passwords.
In the coming days, it will be prompting players on North American servers to change their secret questions and answers, and recommend that mobile authenticator users update their authenticator software.
“We take the security of your personal information very seriously, and we are truly sorry that this has happened,” Morhaime said in his statement.
The company has also provided an FAQ to answer user questions about the attack.
Blizzard is the latest in a string of cyber attacks on games companies, commercial businesses and government agencies that have taken place this year.
