You do realize that Thunderbolt has direct memory access right? It doesn't even need drivers to do malicious actions. It can dump and modify memory at will.

In fact all the USB security hoopla also affects Thunderbolt devices, which can also be reflashed without physically modification.

Thunderbolt is even less secure than firewire, which at least required some support from the OS to dump memory.

USB is an iron fortress compared to those kinds of attacks.
