Steam passwords and credit card information compromised

The hack occurred as a result of an attack on the Steam forums this past Sunday, resulting in unauthorized access of user names, passwords, game purchase history, email and billing addresses, and encrypted credit card information.

In a message sent out this afternoon, Vavle’s co-founder Gabe Newell addressed the status of the attack, and that he believes no encrypted information was successfully accessed.

“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.


As with any compromised information, it’s best to be alert and responsive. Changing your Steam password, as well as your Steam forum password, and watching your credit card statements for any usual activity is strongly advised. You can change your Steam password in the Settings option in the Steam menu within the actual client.
