In the past year or two, there have been several major developments in the rootkit world. Recent milestones include the introduction of the FU rootkit, which uses Direct Kernel Object Manipulation (DKOM); the introduction of VICE, one of the first rootkit detection programs; the birth of Sysinternals’ Rootkit Revealer and F-Secure’s Blacklight, the first mainstream Windows rootkit detection tools; and most recently the introduction of Shadow Walker, a rootkit that hooks the memory manager to hide in plain sight.

Enter Blacklight and IceSword. The authors chose to investigate the algorithms used by both Blacklight and IceSword because they are considered by many in the field to be the best detection tools. Blacklight, developed by the Finnish security company F-Secure, is primarily concerned with detecting hidden processes. It does not attempt to detect system hooks; it is only concerned with hidden processes. IceSword uses a very similar method to Blacklight. IceSword differentiates itself from Blacklight in that it is a more robust tool allowing the user to see what system calls are hooked, what drivers are hidden, and what TCP/UDP ports are open that programs, such as netstat, do not.
