Battle.net has been breached – Diablo III and other data stolen

" "

Blizzard has issued a statement notifying users that Battle.net online service have been breached recently with user data stolen in the process. This breach impacts user data related to games such as World of Warcraft, Diablo III and Starcraft 2.

According to Blizzard’s statement, email addresses for Battle.net users, personal security questions, and information relating to authenticators and scrambled passwords were compromised.


Blizzard doesn’t believe that the stolen information alone is enough to gain access into a user’s account. However, Blizzard urges users to change their password immediately and a mandatory change to security questions will be enforced shortly. It doesn’t appear that credit card information was taken according to Blizzard.


At this time, we’ve found no evidence that financial information such as credit cards, billing addresses, or real names were compromised. Our investigation is ongoing, but so far nothing suggests that these pieces of information have been accessed.

It is a bit concerning that the hackers were able to make off with the authenticator information as I also use a mobile authenticator. Blizzard stated that users will be asked to also update their mobile authenticator software for iPhones and Android devices soon.


In the coming days, we’ll be prompting players on North American servers to change their secret questions and answers through an automated process. Additionally, we’ll prompt mobile authenticator users to update their authenticator software. As a reminder, phishing emails will ask you for password or login information. Blizzard Entertainment emails will never ask for your password. We deeply regret the inconvenience to all of you and understand you may have questions. Please find additional information here.

Just recently, a user revealed that he was able to earn around $10,000 or $1,500 per week by selling loot on the Real Money Auction House. With this kind of money changing hands, I wouldn’t be surprised if Battle.net may have to be fortified like a bank
