There was a report of a user who suddenly had a memory error in WoW. After it crashed, he tried to log in again and had been hacked.
The answer has been found, and warning to you all; there’s a fake wowmatrix site which downloads a trojan. Read report at curse. The fake site looks the same but includes the trojan. They’re using google ads to promote the site. Name’s very similar.
wowmatrix is not the only site being faked though!
I use Curse client (it’s great) and this hack is one more reason you should be so careful with Windows machines. Get a Mac if you can , or at least be super careful.
This whole thing brought to my attention by Stratfu twitter.
