Modchips of the State
Hardware implants and supply chain attacks have been in the news recently, but how feasible are they and what can we do about them? In this talk we'll examine the design of a proof of concept SPI bus hardware implant that has similar capabilities to those described in the Bloomberg/Supermicro article as well as some countermeasures that we can use to try to detect these "modchips" and increase our trust in our systems.
