Blizzard's got a new, automated "Did someone hack your account? We'll get right on it!" retrieval system. You answer some security questions and they change the password, remove Authenticators, restore lost items and all that jazz. Takes 6-12 hours, according to the website.
Scary part is that I've not been hacked in years, but the moment I removed my Authenticator (new phone), I got hacked instantly. Makes you wonder how long they've been trying to get to my account.
Edit: Just logged in to check. All characters are still wearing their gear and it doesn't look like I lost any gold. Received a bunch of random crap in the mail from the GM who handled my ticket, apparently.
