Not a good time for Apple devices! Although this won't help I always recommend Mac users use a anit-virus package. There is no excuse really as there are free ones out there such as Avast's: http://www.avast.com/en-gb/free-antivirus-mac . I also recommend their Android security software which is awesome and much better than Apples built in 'find my phone' feature set.

Hack temporarily turns WoW towns into piles of corpses

Bit late on this one but what a interesting exploit. Would have been infuriating at the time!
