Valve Software founder Gabe Newell has posted an announcement for users of Valve’s Steam game download service to update them on the status of a security investigation that first came to light last November.

Reiterating that Valve has “found no evidence that the intruders took information from [the stolen] database,” Newell added that “it is probable that the intruders obtained a copy of a backup file with information about Steam transactions between 2004 and 2008. This backup file contained user names, email addresses, encrypted billing addresses and encrypted credit card information. It did not include Steam passwords.”

Newell underscored that Valve has no evidence that the hackers compromised any billing addresses or encrypted credit card numbers.
