Friends account is being hacked. Right now..

Q u o t e:
Hi i logged into wow just now and saw my friend online. The only problem is my friend is at my house not, playing wow. He tried to log in and his password was changed and an authenticator was added to his account.

This does look like it's already been addressed, Duffie.

Please do make sure your friend goes over both his system - and his email. They likely got in through the email, but it's also quite likely his system is compromised.
