Rootkits headed for BIOS
Insider attacks and industrial espionage could become more stealthy by hiding malicious code in the core system functions available in a motherboard's flash memory, researchers said on Wednesday at the Black Hat Federal conference.
A collection of functions for power management, known as the Advanced Configuration and Power Interface (ACPI), has its own high-level interpreted language that could be used to code a rootkit and store key attack functions in the Basic Input/Output System (BIOS) in flash memory, according to John Heasman, principal security consultant for U.K.-based Next-Generation Security Software.
