exe2bat reborn in exe2powershell for modern Windows. Initial author ninar1, based on riftor work, and modernized by ycam exe2powershell.

exe2powershell is used to convert any binary file (*.exe) to a BAT file.
The resulting BAT file contains only “echo” command and finally a powershell command to re-create the original binary file.

This kind of tool is usefull during pentesting when an auditor triggers a shell without any upload feature. With only “echo” and “powershell” commands the auditor is able to “upload” any binary file on the targeted system.

  • Main code taken from Riftors “exe2hex”.
  • Adapted for Windows BAT file by ninar1.
  • Modernized to newer Windows systems by Yann CAM

This version is modernized from exe2bat to work with modern Windows version. exe2bat have limitation :

  • Need “debug.exe” available on the target computer (16-bit application removed on Windows 7 x64 but available on Windows 7 x86)
  • Limit input exe to 64kB

exe2powershell replace the need of “debug.exe” by a PowerShell command line available on all Windows since Windows 7 / 2008. There is no more limitation in input exe size.

How to use :

C:\exe2powershell\bin>exe2powershell.exe
