um-tracer - Usermode Virtual Instruction Tracer Demo

um-trace is a demo project/repo which contains an example of how to create a runtime trace of a VMProtect'ed binary (VMProtect 2). 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 vmtracer.
• 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-tracer/ - source code for usermode tracer, includes a hook on LCONSTBZX.

Usage

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

To create a trace file simply run the following:

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