Mood-NT is a linux kernel rootkit suckit2-like for 2.4.x/2.6.x kernels. It can hide processes, files, connections (unix, raw, and ipv6 too), promisc flag and it allows tty sniffing, exec redirection, exec parameters sniffing, has an internal private init script for starting whatever you want on boot. It has a lot of anti-detectors engines and a unique hiding engine hardware based (through the debug registers) that makes it completely stealth on x86 machines. If the kernel changes it automatically reinstall itself on boot.
