Battle.net Hacked: Information Stolen

Battle.net has been hacked and authenticators may not be able to save you. Fortunately, real names, billing addresses, and credit card information remain safe.

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.

However, hackers did manage to gather email account information, associated authenticator information, the answer to the personal security question, and encrypted passwords.

Some data was illegally accessed, including a list of email addresses for global Battle.net users, outside of China. For players on North American servers (which generally includes players from North America, Latin America, Australia, New Zealand, and Southeast Asia) the answer to the personal security question, and information relating to Mobile and Dial-In Authenticators were also accessed. Based on what we currently know, this information alone is NOT enough for anyone to gain access to Battle.net accounts.

The plus side is that the encryption they used is suppose to keep your password secure in this situation.

We also know that cryptographically scrambled versions of Battle.net passwords (not actual passwords) for players on North American servers were taken. We use Secure Remote Password protocol (SRP) to protect these passwords, which is designed to make it extremely difficult to extract the actual password, and also means that each password would have to be deciphered individually. As a precaution, however, we recommend that players on North American servers change their password. Please click this link to change your password. Moreover, if you have used the same or similar passwords for other purposes, you may want to consider changing those passwords as well.

Perhaps to be on the safe side it may be a a good time to change your password, reacquire a mobile authenticator, and chance your security question.

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.
