Valve: Steam user database hacked, no evidence of personal info taken

In a message sent to all Steam users by Valve's Gabe Newell, it was revealed that the vandalizing of the Steam forums, which occurred on November 6, was followed by an intrusion on "a Steam database." The hacked database included usernames, "hashed and salted" passwords, transcripts of game purchases, email and billing addresses, and encrypted credit card info. The message specified that Valve doesn't have any evidence of the intruders taking the credit card numbers or any other "personally identifying information," or that the encryption on said numbers or passwords had been cracked.

The company is investigating the incident, but because a few forum users have been compromised all users must change their passwords during their next forum visit. Steam users aren't forced to change their passwords, but are encouraged to do so, especially if they match their forum passwords. Also, if your bank account, Paypal account, PSN, Xbox Live, email, AIM or, you know, anything, shares your forum password, you should probably change that too -- and then you should probably just move into a log cabin in the woods for a while.

You can read Newell's full message after the break.

Dear Steam Users and Steam Forum Users,

Our Steam forums were defaced on the evening of Sunday, November 6. We began investigating and found that the intrusion goes beyond the Steam forums.

We learned that intruders obtained access to a Steam database in addition to the forums. This database contained information including user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information. We do not have evidence that encrypted credit card numbers or personally identifying information were taken by the intruders, or that the protection on credit card numbers or passwords was cracked. We are still investigating.

We don't have evidence of credit card misuse at this time. Nonetheless you should watch your credit card activity and statements closely.

While we only know of a few forum accounts that have been compromised, all forum users will be required to change their passwords the next time they login. If you have used your Steam forum password on other accounts you should change those passwords as well.

We do not know of any compromised Steam accounts, so we are not planning to force a change of Steam account passwords (which are separate from forum passwords). However, it wouldn't be a bad idea to change that as well, especially if it is the same as your Steam forum account password.

We will reopen the forums as soon as we can.

I am truly sorry this happened, and I apologize for the inconvenience.
