Hackers accessed a Valve server containing the following information:
Encrypted and salted credit card numbers
Encrypted passwords (For the Steam Forums if I'm reading this right; Valve isn't forcing new Steam passwords, only new forum ones)
No proof of credit card misuse right now, but the warning is out.
tl;dr hackers making this world a no-fun-allowed zone. At least it sounds like Valve has gone through greater measures to encrypt our information than a...certain other company. Just going to wait this out- at least Steam won't be going down for a month.
