You should probably speak to the Steam support. If you did save your credit card info on the Steam account and the guy has access to it, you may want to also cancel the card, for your own financial safety.

Contact support. What else would you do?

Call the bank and close the creditcard then you take back your steam account fast :) also change your email password.

Well, if that ever happened to me I would get heart attack on the spot. Did you have Steam Guard activated?

EDIT: Also AFAIK, the CC information on Steam is encrypted, o unless he got his hands on something more than you steam information, he is bluffing, contact Steam Support, your Steam Support is on separate account than your Steam so he shouldn't notice if you contact them.

Update guys, I haven't gotten my password from steam so I believe he set it to his own email...

1) contact your bank and tell them the card is compromised.

2) contact steam support and get your steam account by proving ownership.

Well this is what I do:

• Cancel the credit card.
• Call the bank and tell than that your credit card is compromised.
• Create a new email and secure your steam account with that email.
• Secure your email account with the number phone.
• Change the password
• Contact the Steam Support as soon possible.
• Verify your pc, maybe you have an keylogger. If you want to be sure, reinstall the Windows.

Received the message by e-mail? On Steam? Pigeon carrier?

You were either phished or you use the same password for every website.

Change the account e-mail and password.. Activate Steam Guard, if its activated.. then restart the list of all the computers you have accessed.. You can do that in Preferences..

(Sorry for bad english.. Not sure if you get it..)

I'm not sure, and someone correct me if I'm wrong, but I think as a user you can only see the credit card type and last four digits. He would not only have had to steal your account (relatively easy for a hacker) but he would also have had to have hacked Steam's credit card storage (much more difficult for a hacker, and this guy would have already used your credit card by now if that's what he wanted).

In short, I think your credit card is relatively safe and you should go ahead and contact support and do whatever else it takes to get your account back.

He still needs the 3 characters security code to use your credit card.

block your CC asap with the help of your bank .

did you recently installed the keylogger program got from giveawayoftheday.com?

edit: because some people found out it was sending anonymus log to unknown recipent, and well almost every1 was fckedup with GOTD for releasing such software without checking it.

Damn. That sounds scary.

• Contact your bank and let them know your credit card might be compromised (the number will be on the back of the card)
• Then follow this.
• Change your email password
• Change your steam password (not one that was used before)
• Scan your computer for malware/keyloggers (software I recommend use the free download and activate the trial.)

Boom, you're back to normal!

I submitted a ticket to steam and am waiting for a response. I also closed the card and changed my email password. Thank you for the help everybody! I really appreciate it!!!
