I believe they are going after bnet accounts like crazy right now. Funny that Blizzard's main solution is to pay them even more money for an authenticator. I just logged into my bnet account (mainly to remember what they called the authenticator) and I see they are offering one for free to me though.
Here is there help page on accounts being hacked. Most won't help you considering the first step is talking about in game help (doesn't really make too much sense considering your account is hacked, chances of you being in game and knowing about it are slim).
