HyperDbg is designed with a focus on using modern hardware technologies to provide new features to the reverse engineering world. It operates on top of Windows by virtualizing an already running system using Intel VT-x and Intel PT.
This debugger aims not to use any APIs and software debugging mechanisms, but instead, it uses Second Layer Page Table (a.k.a. Extended Page Table or EPT) extensively to monitor both kernel and user executions.
HyperDbg comes with features like hidden hooks, which is as fast as old inline hooks, but also stealth. It mimics hardware debug registers for (read & write) to a specific location, but this time entirely invisible for both Windows kernel and the programs, and of course without any limitation in size or count!
Using TLB-splitting, and having features such as measuring code coverage and monitoring all mov(s) to/from memory by a function, makes HyperDbg a unique debugger.
Although it has novel features, HyperDbg tries to be as stealth as possible. It doesn’t use any debugging APIs to debug Windows or any application, so classic anti-debugging methods won’t detect it. Also, it resists the exploitation of time delta methods (e.g., RDTSC/RDTSCP) to detect the presence of hypervisors, therefore making it much harder for applications, packers, protectors, malware, anti-cheat engines, etc. to discover the debugger.

Here’s a diagram that shows how HyperDbg works !
Plugins
The plugin framework is not ready for the current version of HyperDbg. Future versions will support plugins.
Donations to charity
We spent thousands of hours on HyperDbg and it’s free and open-source for you, If you want to help to develop HyperDbg, please donate to children in Africa and send a picture of your donation to us, this makes all HyperDbg developers, super happy! Don’t hesitate to send us the pictures, this way we know that we’re doing something useful.
