ion. This convenience comes at a bit of a cost: an external port into your computer's bus and possibly memory! Thunderbolt ports appear on high-end laptops like the MacBook Pro, but also increasingly on PC hardware, and on newer desktop and server motherboards. This proprietary technology is undocumented but problems with it could potentially undermine the privacy and security of users.
This talk chronicles process of exploring these risks through a practical exercise in reverse engineering. Experience the tribulations with reversing Thunderbolt chips, understand the attack strategies for exploiting DMA and see the pitfalls one encounters along the way, while gaining a deeper understanding of the risks of this new feature.
