VMProfiler CLI - VMProtect 2 Virtual Machine Information Displayer

vmprofiler-cli is a CLI program which displays all details of a specified VMProtect 2 virtual machine. This information includes virtual instruction pointer advancment direction, all vm handlers, virtual instruction rva decrypt instructions, vm handler table entry decrypt instruction, and much more.

Build Instructions

Clone the repository and all submodules using git clone --recursive https://githacks.org/vmp2/vmprofiler-cli.git. Then execute the following commands:

cd vmprofiler-cli
cmake -G "Visual Studio 16 2019"

Now you can open vmprofiler-cli.sln, select "Release" and "x64" on the top of the visual studios window. Building should take a few minutes.

usage

Usage: vmprofiler-cli [options...]
Options:
    --bin, --vmpbin        unpacked binary protected with VMProtect 2
    --vmentry, --entry     rva to push prior to a vm_entry
    --showhandlers         show all vm handlers...
    --showhandler          show a specific vm handler given its index...
    --vmp2file             path to .vmp2 file...
    --showblockinstrs      show the virtual instructions of a specific code block...
    --showallblocks        shows all information for all code blocks...
    --devirt               lift to VTIL IR and apply optimizations, then display the output...
    -h, --help             Shows this page
