This is unfortunate, however there is a silver(gold) lining.

I made out like a bandit when my accounts go hacked @6 months ago - pre authenicator. At the time I had about 160k gold and just a ton of other items, mostly enchanting,jewelcrafting mats on bank mules etc. These hackers pretty much cleaned me out and transfered alot of my characters to different servers.

I went thru the procedure and it took about 12 days to get my stuff back and when I got it all back I was blown away. I got around double my gold back and got about 3 times in mats back. My warrior had thunderfury from back in the day and when I logged him on he had his original equipped and another in his bags.
