Features

• Unpack VDM containers of Windows Defender/Microsoft Security Essentials;
• Decrypt VDM container embedded inwards Malicious software Removal Tool (MRT.exe);
• Extract all PE images from unpacked/decrypted containers on the wing (-e switch):
  • dump VDLLs (Virtual DLLs);
  • dump VFS (Virtual File System) contents;
  • dump signatures auxiliary images;
  • dump GAPA (Generic Application Level Protocol Analyzer) images used yesteryear NIS (Network Inspection System);
  • code tin survive adapted to dump type specific chunks of database (not implemented);
• Faster than whatsoever script.

Usage
wdextract file [-e]

• file - filename of VDM container (*.vdm file or MRT.exe executable);
• -e optional parameter, extract all institute PE icon chunks institute inwards VDM later on unpacking/decrypting (this including VFS components in addition to 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 of operations volition survive unpacked/decrypted to source directory equally %originalname%.extracted (e.g. if master copy file c:\wdbase\mpasbase.vdm, unpacked volition survive c:\wdbase\mpasbase.vdm.extracted). Image chunks volition survive dumped to created "chunks" directory inwards the wdextract electrical flow directory (e.g. if wdextract run from c:\wdbase it volition survive c:\wdbase\chunks directory). Output files ever overwrite existing.

Build

• Source code written inwards C;
• Built amongst MSVS 2017 amongst Windows SDK 17763 installed;
• Can survive built amongst previous versions of MSVS in addition to SDK's.
