I always miss lots of firmware news. 😦 I just now noticed this blog post from 11/2015 from Intel Security executives:
Hardware.Next: Diving deeper into the stack—understanding the dangers of hardware and firmware vulnerabilities
https://blogs.mcafee.com/executive-perspectives/hardware-next-hardware-firmware-vulnerabilities-provide-tools-attackers-defenders/
It gives me a big ‘deja-vu’ to the 4/2014 blog post from elsewhere at Intel:
Attackers Expand to Hack Hardware
https://communities.intel.com/community/itpeernetwork/blog/2015/04/15/attackers-expand-to-hack-hardware
I guess if you’re a chip company, this will be your perspective, that attackers are coming from usermode down to attack their hardware.
