Converter - Script to EXE

CONVERTER

Script-to-EXE compiler — reverse-engineered from Bat_To_Exe_Converter (f2ko.de) using Ghidra 12 static analysis, then reimplemented in pure Python.

What It Does

Converts .bat .ps1 .vbs .js .py scripts into standalone Windows .exe files that run without any interpreter installed. Supports invisible mode (no console window), custom icons, and UAC elevation manifest.

How It Works — Discovered via Reverse Engineering

A precompiled stub EXE is copied to the output path
Script content is injected as RT_RCDATA resource (type 10, name 1) via Windows UpdateResource API
Launch metadata (extension + interpreter command) injected as resource name 2
At runtime the stub extracts the resource to a temp file, executes it, then self-cleans

MECHANISM (from Ghidra decompilation)

  input.bat
      |
      v
  stub_x64.exe  --copy-->  output.exe
                                |
                    BeginUpdateResourceW()
                    UpdateResourceW(RT_RCDATA, 1, script_bytes)
                    UpdateResourceW(RT_RCDATA, 2, b"batcmd.exe /c")
                    EndUpdateResourceW()
                                |
                    [at runtime]
                    ExtractResource -> %TEMP%\~xyz.bat
                    ShellExecute("cmd.exe /c %TEMP%\~xyz.bat")
                    Sleep -> DeleteFile(%TEMP%\~xyz.bat)
