  I can't say for certain, but I don't see them claiming to have defeated it,
so I think you're most likely right.

  Heh, I have the facilities available to me to write custom USB devices.
I've managed to make the kernel divide by zero entirely accidentally, but I
haven't had time to try finding an exploitable overflow.  I just *know* they
must be there, though.

  I was very impressed by their ndis-hooking keylogger and its simple
technique for exfiltration.  Although I'm sure quite a lot of IDSen will trip
on it, it may not be covert, but it is very clever, and done in a very small
amount of code.
