VMPAttack

A Work-In-Progress VMP to VTIL lifter. Works for VMProtect 3.X x64.

Usage

Literally drag + drop the unpacked victim file onto VMPAttack.exe. Lifted VTIL routines will appear in a folder named "VMPAttack-Output".

Advanced Usage

All lifting functionality depends on the vmpattack root class object. This object can easily be constructed using a byte vector of the target image. You can lift any routine manually by passing the VMEntry RVA and entry stub value in a lifting_job structure to the vmpattack::lift function.

lifting_jobs can be automatically generated by providing the RVA of the entry stub (see above) to the vmpattack::analyze_entry_stub function.

Example usage:

   std::vector<uint8_t> buffer = read_file( file_path );

   vmpattack instance( buffer );

   if ( auto result = instance.analyze_entry_stub( my_rva ) )
   {
       if ( auto routine = instance.lift( result->job ) )
       {
           vtil::optimizer::apply_all_profiled( *routine );
           vtil::save_routine( *routine, "C:\\my_routine.vtil" );
       }
   }

Building

Building in VS is as simple as replacing the include/library directories to VTIL/Keystone/Capstone in the vcxproj.

The project now also universally supports CMake and platforms other than Windows.

The project requires C++20.

Issues

Stability is the main issue. Sometimes the lifter or optimizer can hang unexpectedly, or fail to lift certain branches. The lifter also does not currently handle switch tables.
