Valve Software co-founder Gabe Newell warned in a message to users that a forum hack found on November 6 had also touched on vital account information. After an investigation, the Portal 2 developer found that the unnamed intruders had gotten into a database that also had account names, e-mail, encrypted credit card numbers and passwords, and purchase records. While Valve had no reason to think the account information itself had been compromised, Newell advised gamers to watch their credit card activity "closely."
