Researcher: Malware can reside in peripheral components

Researcher: Malware can reside in peripheral components
Malware writers are developing sophisticated bugs that attack a computer's direct memory access from within peripheral components, including graphics and network cards, researcher Patrick Stewin says. Stewin says he has developed a way to root out one such virus, dubbed DAGGER, that targets 32- and 64-bit Windows and Linux systems. "DMA-based attacks launched from peripherals are capable of compromising the host without exploiting vulnerabilities present in the operating system running on the host," Stewin wrote in a paper. "Therefore they present a highly critical threat to system security and integrity."
