Although this is not the exploit itself apparently a group of Exploit/hackers has been going around ganking entire servers in the EU realms and I thought I should bring this to light because it is interesting exploit news perhaps they found a way to use GM commands on live servers sure as hell looks like it from this video. Blizzard is deleting threads left and right trying to hide the fact that this happened so it must be something big, US servers just went down for restarts. here is a video and a link to the wow insider article as well.
Reports: Entire cities dead on certain realms
Now just as a reminder if this is hacking and not exploiting it is highly illegal the kind of illegal where the FBI kicks in your door and takes all your electronics and you. Still seemed like an interesting story the owned core community might enjoy
