Design flaw in Intel processors opens door to rootkits, researcher says

A design flaw in the x86 processor architecture dating back almost two decades could allow attackers to install a rootkit in the low-level firmware of computers, a security researcher said Thursday. Such malware could be undetectable by security products. The vulnerability stems from a feature first added to the x86 architecture in 1997. It was disclosed Thursday at the Black Hat security conference by Christopher Domas, a security researcher with the Battelle Memorial Institute. By leveraging t...
