from what i've heard from multiple posts is that they don't necessarily detect the actual software, they detect a point in the account log where an outside program hooks/injects into wow. Who really knows other than blizzard software engineers? Until the server/client software is fully reversed engineered we will probably never know. For that to happen it would almost certainly have to be a blizzard employee that's signed a nondisclosure agreement and if they found out it happened they'd most likely know who was the source of the leak. About the only thing I can think of is that Bossland would have to develop some sort of morph to basically trick wow into thinking the hook/injection is linked to some sort of approved plugin or something. this is, of course, all conjecture. i'm no computer programmer so i'm not even sure if any of this is even possible.
