Presentation Title Breaking Virtualization by Switching to Virtual 8086 Mode
Presentation Abstract

Over the last few years, different attacks involving switching the cpu mode to SMM have been detailed. In this talk, we will expose how abusing an other mode of the intel cpus, namely the virtual 8086 mode, even when heavily emulated like inside a virtual machine, can help an attacker get direct access to the hardware, and ultimately break virtualization under certain conditions.
