This was not so much a hack but rather a system error, or according to Valve, an incorrectly cached version of Steam Store pages. Now it has been several months since the incident, and it looks like Valve has finally gotten around to issuing an apology by sending out emails to its Steam users in which not only did they apologize, they also shared additional details of the incident.
For starters it seems that the window in which users were affected was quite small. “If you accessed the Steam Store between 11:50 PST and 13:20 PST on December 25th, your account could have been affected by this issue. If you did not use the Steam Store during that time, your account was not affected.”
They also wanted to point out that despite this, your Steam account has not been compromised and that it is impossible to make fraudulent purchases based on this. “This event did not make it possible to compromise your Steam account or make a fraudulent transaction from your account, but we want you to be aware of what information could have been seen by another Steam user. We’re sorry this happened and have taken steps to prevent this problem from occurring in the future.”
