Demigod: The Art of Emulating Kernel Rootkits

Kernel rootkit is considered the most dangerous malware that may infect computers. Operating at ring 0, the highest privilege level in the system, this super malware has unrestricted power to control the whole machine, thus can defeat all the defensive and monitoring mechanisms. Unfortunately, dynamic analysis solutions for kernel rootkits are severely lacking; indeed, most existing dynamic tools are just built for userspace code (ring 3), but not for Operating System (OS) level. This limitation forces security researchers to turn to static analysis, which however proved to be very tricky & time consuming.
