um-hook - Usermode Virtual Instruction Hook Demo

um-hook is a demo project/repo which contains an example of how to hook a virtual instruction and alter its results. The binaries in this repo are not packed for simplicity sake, however in later demo's I will be applying packing to the executable.

Contents

  • dependencies/ - this project is dependent on vmhook.
  • refbuilds/ - binaries protected with ultra virtualization and no packing. These bins are for you to mess with!
  • src/ - source code for the usermode tracer.
    • vmptest/ - source code for the the test bins
    • um-hook/ - source code for usermode hook, includes a hook on LCONSTBZX.

Usage

First download the repo with git clone --recursive https://githacks.org/vmp2/um-hook.git, then compile the um-hook by opening demo.sln inside of src/. There should be an executable called um-hook.exe in x64/Release. This hook demo program is compiled for the first vmptest binary in the refbuilds directly.

To create a trace file simply run the following:

um-hook.exe --bin vmptest.vmp.exe --table 0x6473 --base 0x140000000 --out test.vmp2
