sound exactly like another of the LYN poster who said he been hack
and the hacker put the Blizzard Authenticator in his account. sealing him from his own account, he can't do anything much.
have your check your armory yet? and your alt as well(above lvl10 ones)
its is best email the link from the official wow forum and wait for them to respond.
i know blizzard aware of this and trying to figure out which account is been hack and which one is not(goldfarmer a/c).
only untill they can find a solution, then they will reply to you.
or they will just give you the standard"we are well aware of this problem and apology for the inconvinion. please delete your WTF folder and may the light guide you on your journey".

don't buy yet, well maybe just buy the ones that offer exclusive pet.

rumour has it that, Blizzard might make authenticators mandatory for all accounts.

i got this from wowhead's blog

Trojan succesfully hacks Authenticator Protected Accounts
A new virus spawned on the internet a few days ago and seems to be the first trojan capable of hacking a WoW account protected by an Authenticator. It was confirmed by Blizzard a few hours ago.


After looking into this, it has been escalated, but it is a Man in the Middle attack.

http://en.wikipedia.org/wiki/Man-in-the-middle_attack

This is still perpetrated by key loggers, and no method is always 100% secure.

Basically, what the virus does is fairly simple after you're infected :

•The next time you log in World of Warcraft, the game asks for your Authenticator code.
•The virus intercepts it, send it to another server, and sends a wrong one to Blizzard = You get an error.
•The people behind the virus now have a few seconds/minutes to use the "real" code while it's valid to change your password / empty your account / guild bank.

How to check if you're infected
Just search for a file named "emcor.dll" on your computer, it is most likely located in "C:\Users\(Your user name)\AppData\Temp" but I suggest that you check everything just to be sure. If you do find the file, delete it and make sure you update your anti-virus to prevent any further problem.

To be honest, if you found this file your account is probably already compromised.

What does it mean exactly?

•Yes, you can get hacked even if you have an authenticator, the chances are MUCH lower but you're not invulnerable.
•It definitely isn't an excuse to not have an authenticator. We're talking about a single virus here and the authenticator will save your ass 99% of the time.
•Get a decent anti-virus, buy an authenticator, you'll be safe.
