IRVINE, Calif.–(BUSINESS WIRE)–Blizzard Entertainment, Inc. today notified its players that there was unauthorized access to some Battle.net account information.
The unauthorized access included email addresses associated with Battle.net accounts in all regions, outside of China. Additional information from accounts associated with the North American servers (which generally includes players from North America, Latin America, Australia, New Zealand, and Southeast Asia) was also accessed, including cryptographically scrambled versions of passwords (not actual passwords), the answer to a personal security question, and information relating to Mobile and Dial-In Authenticators. It’s important to note that at this time, Blizzard does not believe this information alone is enough to gain access to Battle.net accounts.
Based on Blizzard’s investigation to this point, credit card and other customer payment data does NOT appear to have been accessed or affected. As a precaution, however, Blizzard encourages players to change their Battle.net password and any similar passwords used for other purposes.
Upon discovery of the unauthorized access, Blizzard took quick action to close off the unauthorized access and notify appropriate law enforcement. Investigations are ongoing and Blizzard continues to work with authorities and security experts.
Additional information regarding this matter is available on the Company’s website at http://www.blizzard.com/SecurityUpdate.
Blizzard Entertainment president and co-founder Mike Morhaime issued the following statement:
Players and Friends,
Even when you are in the business of fun, not every week ends up being fun. This week, our security team found an unauthorized and illegal access into our internal network here at Blizzard. We quickly took steps to close off this access and began working with law enforcement and security experts to investigate what happened.
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.
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.
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.
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.
We take the security of your personal information very seriously, and we are truly sorry that this has happened.
