Hackers hide rootkits in CPU’s
Called a System Management Mode (SMM) rootkit, the software runs in a protected part of a computer’s memory that can be locked and rendered invisible to the operating system, but which can give attackers a picture of what’s happening in a computer’s memory.
The SMM rootkit comes with keylogging and communications software and could be used to steal sensitive information from a victim’s computer. It was built by Shawn Embleton and Sherri Sparks, who run an Oviedo, Florida, security company called Clear Hat Consulting…
