Dear Steam Users and Steam Forum Users,
Our Steam forums were defaced on the evening of Sunday, November 6. We began investigating and found that the intrusion goes beyond the Steam forums.
We learned that intruders obtained access to a Steam database in addition to the forums. This database contained information including user names, hashed and salted passwords, game purchases, email addresses, billing addresses and encrypted credit card information. We do not have evidence that encrypted credit card numbers or personally identifying information were taken by the intruders, or that the protection on credit card numbers or passwords was cracked. We are still investigating.
here are some suggestions:
* Change your Steam password, just in case. If you were using a weak password before, take this opportunity to choose a decent one.
* Keep an eye on your credit card statement and report any unexpected transactions.
* Consider not storing your credit card data on Steam's servers. You don't have to. You can choose to enter it every time you need it instead.
* Consider enabling Steam Guard. If you do, Steam will email you every time you (or someone else) logs in from someone else's computer.
* Send an email to Steam asking why they encrypted credit card data and passwords, but apparently not the rest of its users' personally identifiable information.

Nothing to add really, but I'm pissed off and worried.
