Steam users will find a message from Gabe Newell when they next sign into the service.
“Our Steam forums were defaced on the evening of Sunday, November 6,” begins the message. “We began investigating and found that the intrusion goes beyond the Steam forums.”
It appears intruders got access to a Steam database in addition to the forums. The database contained “user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information.”
Valve claim that whilst they don’t have any evidence that the card numbers or personal information were taken, they are “still investigating” and suggest you “watch your credit card activity and statements closely.”
All Steam forum users will have to change their passwords the next time they log in. “If you have used your Steam forum password on other accounts you should change those passwords as well,” advises the message.
We remind all users to ensure passwords are unique for every site and service.
