Since the introduction of FU, the rootkit world has moved away from implementing system hooks to hide their presence. Because of this change in offense, a new defense had to be developed. The new algorithms used by rootkit detectors, such as BlackLight, attempt to find what the rootkit is hiding instead of simply detecting the presence of the rootkit's hooks. This paper will discuss an algorithm that is used by both Blacklight and IceSword to detect hidden processes. This paper will also document current weaknesses in the rootkit detection field and introduce a more complete stealth technique implemented as a prototype in FUTo.
