Steam, the online gaming network run by game company Valve, confirmed Thursday that its forums had been hacked and warned users to keep a close eye on their credit card statements.

The service's forums had been defaced earlier in the week, resulting in some gamers receiving e-mails from a hacking Web site, Kotaku reported.

On Thursday, Valve co-founder Gabe Newell left a message on the company's forums confirming the intrusion, saying that all forum passwords will be reset and adding that the attack "goes beyond the Steam forums." While there is evidence of a deeper intrusion, the company is not yet requiring all Steam users to reset their account passwords, which are separate from forum accounts.

"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," Newell wrote. "We are still investigating."

He added that there have been no reports that Steam accounts were compromised, but advised users to change their passwords as a precaution.
