Hacked

Q u o t e:

This has already been looked into - seems we didn't find any damages, they just used your account to do some very very bad things.

If you find damages we didn't initially identify, please do let us know as soon as possible.

You should have received a new password.

What is vital right now is finding out HOW they got your information. If the source still exists - the changes of them coming right back are VERY high.

You may also want to look into getting an authenticator for your account. It's no substitute for good security habits, but it will help keep them out of your WoW account.
