It seems like a pretty valid concern. Part of the next generation of rootkits seems to be targeted at SMM-level rootkits (termed "ring -1" by some) that are installed in the BIOS. They are practically undetectable once installed, and can punch through hypervisor protections too. I think that is also part of the author's concern with Intel ME being present on all systems. It is a separate microcontroller in the chipset that has power on the level of "ring -3" (I believe it is used to implement much of the new SGE instruction set, for example). |
