The idea that a gaming company would be hacked is certainly old news these days, but when it ends up being a company like Blizzard Entertainment who holds email address and personal information for millions of people, it's definitely worth paying attention to. Mike Morhaime, Blizzard CEO, just wrote an open letter to the Blizzard community letting them know that Battle.net security was breached, allowing hackers to obtain access to email addresses and for North American players the answers to both security questions and the data that lets people access your authenticators was also compromised.
For those who play any games using a Battle.Net ID, now is the time to change your password. While some passwords were accessed they were secured using cryptography, so you should still have access to your account. However, it's best to be safe rather than sorry when it comes to these sorts of things.
You'll find a copy of Morhaime's statement after the break. I am saddened once again that the technological community is eating itself from within. Unfortunately with this case there is money to be made from these accounts, either through manipulation of the Diablo III Real Money Auction House, or from selling items from World of Warcraft accounts. This is me shaking my head as I head off to change my passwords. For more information about the breach Blizzard has set up an FAQ.
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.
