Intel Security has their annual FOCUS conference, in Las Vegas in a few weeks.
I may have missed others, but there is at least ONE interesting presentation at this event:
Breaking Bad BIOS — The Art of BIOS Attacks
Oleksandr Bazhaniuk, Security Researcher, Intel Security
Recent attacks against Basic Input/Output Systems (BIOSs) attracted attention due to their ability to enable stealthy and highly persistent malware capable of compromising software applications, operating systems, and hypervisors. Some can bypass secure OS boots, enable attacks on encrypted disks, and even allow additional malware installs.
* Understand current BIOS attacks and attack surfaces
* Understand platform level tools and mitigations
* Observe an actual attack demo
