Rootkits coming to your motherboard

The recent media attention on rootkits has been focused on installed software, but according to some security professionals at the Black Hat Federal security conference, these kits could be installed on your motheboard's BIOS chip in the near future. Often running a programming language of their own, these chips store the basic command and control functions of the computer. In an article written by Robert Lemos of SecurityFocus, security researchers say that rootkits could take advantage of this language and are the "next logical step".

BIOS chips contain machine language which interprets hardware commands coming from the Operating System into instructions the CPU and other peripheral devices can use. Researchers theorize that with the proper tools someone could install their own malicious software that would be undetectable by the operating system. There have been viruses in the past, like the Chernobyl or CIH virus, which have tried to erase your BIOS information, but a rootkit would be the first time when someone has tried to actually have malicious piece of software reside on the chip.
