Karsten Nohl and Jakob Lell present BadUSB at Black Hat 2014, showing that USB controller firmware can be reprogrammed to impersonate other device types. They demonstrate system compromise and a self-replicating USB threat that current defenses cannot detect.

Zoz's DEF CON 23 talk explores practical, often explosive ways to destroy data and hard drives quickly. It tests methods such as thermite and other physical techniques for rapid destruction.

An AWS re:Invent 2018 session diving into the Nitro system, a set of hardware offload and security building blocks behind next-generation EC2 instances. It covers the design and architecture and how Nitro enables new instance types.
