Valve Corp. this week said a database in the Steam digital distribution and online gaming service was hacked by intruders.
The company said hackers obtained access to a database that included user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information.
It added it had no evidence that encrypted credit card information was taken or if credit card protection or passwords were cracked by intruders.
Earlier this week, the company said unauthorized users gained access to the Steam forums which did compromise a few forum accounts.
The Playstation Network division in May incurred an unauthorized security breach that crippled the online service for several weeks.
