I like the part about them offering to demonstrate for Apple... and Apple essentially saying "don't call us, we'll call you." or "Ho, hum." Their basic understanding of permissions on OSX seems a bit flawed.
On the other hand, their publishing this MAY attract someone a little more competent...
Okay fine, but what modern OS lets you do that? I mean, if you're using an OS that doesn't abstract the hardware, and lets user code talk directly to the hardware, this is just the latest in a series of about 60 million ways that someone can futz with your machine. On the other hand, none of the NT derivatives would let you do that. Neither would OS X. Neither would any Unix variant. So who's in danger here? The people still running Win95 and MacOS 9? Not exactly a growth market for virus writers, I think ;)
