But at the eleventh hour, the talk was cancelled due to pressure from Maynor's employer, SecureWorks, apparently at the behest of Apple (though one colleague at the show said she spoke to an Apple employee in the audience who denied that Apple had leaned on SecureWorks).
It was clear from the remarks that Cache was very angry about this. His and Maynor's research has been widely questioned by security researchers and defenders of the Mac, who accused the two of bait-and-switching or worse. It seems he'd been looking forward to clearing his good name, and also clear that he felt that Apple and SecureWorks had maligned him.
Cache sent me the text of his remarks:
Let's recap this thing.Link (Thanks, Johnny!)
We give a talk saying that device drivers have lots of bugs.
We demo one bug in Apple.
A few days later, when Apple starts flaking on a patch, we tell them we are going to do a live demo of it at ToorCon, so it would be a good idea to get it patched before that.
Apple says that it doesnt exist, and we didnt talk to them about it.
A few weeks later (1 week before ToorCon) they patch it, and say we had nothing to do with it.
One day before the talk, secureworks and Apple get together to and manage to stop dave from coming. They also issue a cutesy press release
Update: In reference to several people who've emailed me already on this -- the talk was indeed cancelled due to outside pressure, as confirmed by ToorCon's organizers.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
