If you are a gamer that plays games on Steam or has purchased games on Steam before you need to watch your credit cards. Steam was hacked this week and at first it looked like maybe only the forums were hacked. As it turns out the hackers got into their databases including some that held encrypted credit card details.
Valve says that at this point it has no evidence that the credit card data was stolen or that the encryption was broken. The investigation is ongoing though. Valve is warning buyers to check their credit cards to be sure they aren't used without permission. The users are also being warned to change their passwords on the forums and accounts.
Valve notes that panic isn't needed, but users need to be vigilant on their credit card info. This is the latest in a rash of hacks this year that have resulted in major data breaches in the public and private sector. Users of Steam appear so far to have got off much easier than the users of the PSN when it was hacked.
