A debugger library using VEH.

VExDebugger

A debugger library using VEH.

What is it ?

This is a simple debugger library for monitoring data access and writing using hardware breakpoints which manages debugging using the Windows Exception Handling system (inspired by VEH of the Cheat Engine).

How to use this?

You can compile your own project using the Debugger library or you can use one of the ready-made examples using the lib. In the examples you will find ways to debug your own executable or create a dll to attach to another process and debug it. (use an injector for this.) And Add the addresses you want to know who writes or accesses.

This example uses ImGui

Hierarchical planning

Todo

Description

Here will be a list of things that need to be resolved in the future or new things I want to add.
This can take a good one until everything is done.

Improvements

• Readme, explain better the project and give some examples of code
• Structure the code for a main class to avoid so much global variable
• Change the samples interface

Possible problems

• Try to avoid any kind of racing conditions on the list or handlers

Add new features / future ideas

• Spoof hardware breakpoints options
  • Using AddVectoredContinueHandler
  • Hooking NtGetThreadContext
  • Hooking NtContinue
• Add trigger callback option to use conditions
• Module or Threads Filters in the trigger, and exclude options
• Add instruction trace for breakpoint execution
• Add other options for trigger breakpoints, type of software breakpoints or page guard
• Hook using breakpoint

References

• x86 debug register
• Prefer Locks to Mutexes
