Synthetic Overload

Steam is currently compromised. If you click on your account name at the top right in the Steam window, you will most likely see the account information of someone else. This is a serious breach. Do not purchase anything right now or add money to your Steam wallet. In fact, if you can access your own account page, you might want to delete your personal information including credit card number.

I'm not posting this message lightly. Users are reporting their Steam wallet being used to purchase games for other people.
