Answer» From PCWorld.com through Yahoo! News: Partial quote (see link for full article): Quote Security researchers have developed a new type of malicious rootkit software that hides itself in an obscure part of a computer's microprocessor, hidden from current antivirus products. 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. The proof-of-concept software will be demonstrated publicly for the first time at the Black Hat security conference in Las Vegas this August. Very interesting..! Wow this is very interesting. However, the article mentioned it is hardware dependent and as the article mentioned, it would be real hard for something to get created and spread out to a wide audience. What I'm curious about is if it's hardware dependent and something that could be rendered invisible to the OS how would a antivirus or other protection program help protect against something like this?Quote it would be real hard for something to get created and spread out to a wide audience.
