I got hacked

Q u o t e:
This character right here is currently being hacked. They have put an authenticator on the account and i cannot change the password. Please help.

The password has been changed, please check your email - you should have access again.

It's vital that the source of this be found or the chances are very good they'll be right back.

This has also been reported for you, so the investigation is already entered. It will be a few days before you hear back on that.

This sticky should prove useful.

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.

first how do i get rid of the authenticator that was attached to the account by the hacker?

Have you tried to access the account? It shouldn't be there any longer. If you see that box on your login screen ignore it.
