I used to talk about the possibility of a virus or worm writing boot code on hard drives, or flashing devices with new configurations, or even entirely new code. It seems there is now a trojan out there that does just that. Yes the site is in Chinese. But it describes a trojan that flashes Award BIOS code to add a few new functions on bootup.
Symantec has more details on how it infects the hard drive Master Boot Record (MBR) and specifically targets and alters the Award BIOS. Other BIOS brands are not affected.
