....In this presentation, we will share our work exploring recent changes in the UEFI firmware security runtime using one of the most recent Intel CPUs as an example. The presentation will cover the evolution of firmware mitigations in SMM/DXE on x86-based CPUs and a discussion about the new attacks on Intel Platform Properties Assessment Module (PPAM), which are often used in tandem with Intel SMI Transfer Monitor (STM). These topics have never been publicly discussed from the offensive security research perspective.
