I got hacked last night!
The worst part was, I was on when it happened. I was in Elwin, with 600g, about to buy my epic mount for my 60 pally, and I got disconnected. When I tried to reconnect, my password wouldnt work. Right away I thought hackers, so I submitted a pw change, and, stupid me, the email address they had for me was old and inactive, so I couldnt get the new one to log back in and bump them out of the account.
This morning I found they'd cleaned out all 5 of my level 70s, badges, banks, gear, everything, and I'm a GM of a guild, so they took half our guild bank. Blizz has been supremely helpful and restored all but my gold, badges and gbank items within an hour of my opening a ticket. Now I'm running all the spyware/keylogging software I can get my hands on to clean up whatever wormed it's way into my computer and caused this.
A word of warning - a number of Eonar GM's have been hacked recently and had their gbanks raided. So if you're a GM, be careful. Change your password, run safety software. Don't let them get you too!
