As Spaced first pointed out on the forums, everything Battle.net related has been hackaroonied. This means all e-mail addresses, answers to security questions, enough info to compromise mobile authenticators, and encrypted passwords.
So, basically: CHANGE YOUR BNET PASSWORDS IN ORDER TO PROTECT YOURSELVES! Make sure you DON'T CHANGE IT TO ANYTHING YOU USE ELSEWHERE just in case there's another exploit around the corner. And, of course, DELIST any mobile authenticators you use and add a different one.
If you're the type that wants links to reliable sources before going all out changing your passwords (and you should be!), here's an article on Forbes and the official statement from Blizzard.
I realize this isn't really in the scope of what is usually put in TLD announcements, but this seemed too important not to address. Even if only one or two of you get the info here first, then it was worth doing.
Good luck!
ps. If you have any questions that you feel we can help with, or even if you just want to discuss the situation, feel free to post in the thread on the forums linked below and we'll do what I can to give you a hand.
