Rootkits are a type of malware which are dedicated to hiding the attacker’s presence on a compromised system. This class will focus on understanding how rootkits work, and what tools can be used to help find them.

This will be a very hands-on class where we talk about specific techniques which rootkits use, and then do labs where we show how a proof of concept rootkit is able to hide things from a defender. Example techniques include
•Trojaned binaries
•Inline hooks
•Import Address Table (IAT) hooking
•System Call Table/System Service Descriptor Table (SSDT) hooking
•Interrupt Descriptor Table (IDT) hooking
•Direct Kernel Object Manipulation (DKOM)
•Kernel Object Hooking (KOH)
•IO Request Packet (IRP) filtering
•Hiding files/processes/open ports
•Compromising the Master Boot Record (MBR) to install a “bootkit”

The class will help the student learn which tools to use to look for rootkits on Windows systems, how to evaluate the breadth of a tool’s detection capabilities, and how to interpret tool results.
