Usage

  • wdextract file [-e]
  • file - filename of VDM container (*.vdm file or MRT.exe executable);
  • -e optional parameter, extract all found PE image chunks found in VDM after unpacking/decrypting (this including VFS components and emulator VDLLs).

Example:

  • wdextract c:\wdbase\mpasbase.vdm
  • wdextract c:\wdbase\mpasbase.vdm -e
  • wdextract c:\wdbase\mrt.exe
  • wdextract c:\wdbase\mrt.exe -e
Note: base will be unpacked/decrypted to source directory as %originalname%.extracted (e.g. if original file c:\wdbase\mpasbase.vdm, unpacked will be c:\wdbase\mpasbase.vdm.extracted). Image chunks will be dumped to created "chunks" directory in the wdextract current directory (e.g. if wdextract run from c:\wdbase it will be c:\wdbase\chunks directory). Output files always overwrite existing.

Build

  • Source code written in C;
  • Built with MSVS 2017 with Windows SDK 17763 installed;
  • Can be built with previous versions of MSVS and SDK's.
