Is there anything that players need to do right now to protect themselves?
While there is currently no evidence that any of the password or player data has been misused, we encourage our North American players to change their passwords. Click here to login and change your password.
In the coming days we will implement an automated process for all users to change their secret questions and answers, as a precautionary measure. We'll also prompt mobile authenticator users to update their authenticator software.
Additionally, while Blizzard has no indication that any of your information was shared with any other unauthorized parties or that there has been any unauthorized use of your data, we urge all members of our community to closely monitor all of their online accounts.
Players should also be wary of fraudulent emails (phishing). Unfortunately, because email addresses were exposed, it is entirely possible that this could result in an increased, targeted phishing campaign being sent to our users. Check this page for tips on how to spot and avoid these types of fraudulent emails. Back to top
What data was affected?
Here's a summary of the data that we know was illegally accessed:
North American-based accounts, including players from Latin America, Australia, New Zealand, and Southeast Asia
Email addresses
Answers to secret security questions
Cryptographically scrambled versions of passwords (not actual passwords)
Information associated with the Mobile Authenticator
Information associated with the Dial-in Authenticator
Information associated with Phone Lock, a security system associated with Taiwan accounts only
Accounts from all global regions outside of China (including Europe and Russia) Back to top
Email addresses
China-based accounts
Unaffected
At this time, there’s no evidence that financial information of any kind has been accessed. This includes credit cards, billing addresses, names, or other payment information.
What information related to Mobile and Dial-In Authenticators was exposed? What about Phone Lock?
With regard to Dial-In Authenticators, hashed (not actual) phone numbers were accessed. This is phone data from the relatively small number of people who opted into the program.
With regard to Mobile Authenticators, information was taken that could potentially compromise the integrity of North American Mobile Authenticators. We have no evidence that other regions were affected. We are working quickly to provide software updates to users.
Additionally we believe the integrity of the physical authenticators remains intact.
The information relating to Phone Lock represents a small number of hashed (not actual) phone numbers from Taiwanese players who opted into this service and had a North American Battle.net account.
Was the physical authenticator compromised?
We believe the integrity of the physical authenticators remains intact.
How did this happen?
Like all companies doing business online, it is not an uncommon occurrence to experience outside parties trying to illegitimately gain access to the operation’s structure at some level. We are continually upgrading our security technologies, policies, protocols and procedures to protect our customers and our games against the threats that increasingly arise in today’s online world.
When did Blizzard learn of the unauthorized access?
The trespass into our internal network was detected by us on August 4, 2012.
Why did Blizzard announce this on August 9?
We worked around the clock since we discovered the unauthorized user to determine the nature of the trespass and understand what data was accessed. Our first priority was to re-secure our network, and from there we worked simultaneously on the investigation and on informing our global player base. We wanted to strike a balance between speed and accuracy in our reporting and worked diligently to serve both equally important needs.
What action has Blizzard taken?
Upon learning of the unauthorized access, we worked quickly to re-secure our network. Afterward, we immediately notified law enforcement as well as security experts and launched an ongoing investigation to determine what had occurred. We also took steps to notify players, which happened in a matter of days from the time we discovered the illegal access.
Was any personal or financial information accessed?
At this time, there is no evidence that financial information was affected or accessed. There's also no evidence that personal information such as real names or billing addresses were accessed.
What can you tell us about the scrambled passwords that were accessed?
Cryptographically scrambled versions of passwords for North American players were accessed, protected by Secure Remote Password (SRP) protocol. This information alone doesn't give unauthorized users the actual passwords -- each password would need to be deciphered individually. The added layer of protection from SRP makes that process computationally very difficult and expensive.
Why not immediately invalidate the secret questions and answers that were compromised?
This was a difficult decision to make but in the end we believe that keeping the secret questions and answers in place still provides a layer of security against unauthorized users who don't have access to the compromised data. In the meantime, we are working quickly to create a mechanism for players to change the secret question and answer on their account. Our customer service staff will also know to use additional measures to verify player identities and not rely solely on secret question and answer.
Why not immediately revoke the mobile authenticators?
Similar to the decision surrounding secret question and answer, we still believe that keeping mobile authenticators active provides a layer of security against unauthorized users who don't have access to the compromised data. In fact, the mobile authenticator information by itself won't grant access to a Battle.net account -- that still requires the actual password as well. We are working quickly to deploy new mobile authenticator software and will notify players to update as soon as it's available.
Are you taking additional security measures as a result of this occurrence?
We are continually upgrading our security technologies, policies, protocols and procedures to help protect our customers and our games, and will continue to monitor the situation closely.
Teams have also been working around the clock in an ongoing investigation with law enforcement and security experts, to gain a more detailed understanding of what happened. As we conclude the investigation there will be lessons learned that can help strengthen our security going forward.
