Debuggers 3301: HyperDbg


About This Course

This tutorial is called "Debuggers 3301: HyperDbg" or "Reversing with HyperDbg" which is a comprehensive course focused on teaching reverse engineering techniques using a hypervisor-assisted, user-mode, and kernel-mode Windows debugger called "HyperDbg". This course is designed for individuals interested in analyzing, fuzzing, and reversing software using modern hardware technologies.

Throughout the course, you will learn how to leverage HyperDbg's unique features to conduct in-depth analysis of both kernel and user executions. The debugger operates on top of Windows by virtualizing a running system using Intel VT-x, without relying on APIs and traditional software debugging mechanisms. It extensively utilizes the Second Layer Page Table (Extended Page Table or EPT) to monitor and track code execution.

HyperDbg Debugger offers unique features such as hidden hooks that are both fast and stealthy, mimicking hardware debug registers without any limitations in size or count. Additionally, with capabilities like TLB-splitting, code coverage measurement, and monitoring mov(s) to/from memory by a function, HyperDbg stands out as a powerful and innovative debugger.

HyperDbg avoids using standard debugging APIs, making it undetectable by classic anti-debugging methods. It also resists time delta exploitation methods, such as RDTSC/RDTSCP, to detect the presence of hypervisors, further enhancing its ability to evade detection by applications, packers, protectors, malware, anti-cheat engines, and more.


Participants should have a basic understanding of reverse engineering concepts and familiarity with Windows operating systems. Prior knowledge of assembly language and debugging techniques will be beneficial for getting the most out of this course.

If you need to brush up on reverse engineering fundamentals, we recommend exploring resources such as "Debuggers 1011: Introductory WinDbg " and "Debuggers 2011: Intermediate WinDbg " and also you should have knowledge of OS internals fundamentals (e.g. paging, interrupts, MSRs, port IO, etc), at least to the level covered in Arch2001.

Frequently Asked Questions
