It has come to my attention that certain rootkits evade detection by hiding in an HDD’s Host
Protected Area or in the Device Configuration obverlay area, both of which are generally not visible to the user. Hdparm and other tools such as the Sleuth kit (as well as some physical write blockers used by computer forensics professionals) supposedly let you disable both the HPA and the DCO, meaning that it should be possible to securely wipe all your data, including viruses, worms, trojans, rootkits, etc.

My question is as follows: is it possible for some piece of malware to infect a user’s graphics card, motherboard, memory, etc? I know that ClamWin has the ability to scan memory for malicious programs, but is there any chance some of these programs are somehow hiding in any of the non-HDD components, lingering in obscure hidden areas of one’s motherboard or graphics card or whatnot.
