The Backdoor Factory (BDF) is a Python command-line tool that patches Windows PE, Linux ELF, and macOS Mach-O executables with user-supplied shellcode while preserving normal execution of the original binary. It is intended for security professionals and researchers performing penetration testing and binary infection research.

Use cases

  • inject shellcode into a PE executable
  • patch ELF binaries for red team exercises
  • backdoor a Mach-O binary on macOS
  • test antivirus detection of infected binaries
  • patch UPX-packed executables
  • learn binary patching and code injection techniques

When to choose

  • you are a penetration tester or security researcher needing to patch executables with shellcode
  • you need cross-format support for PE, ELF, and Mach-O binaries
  • you want a well-known open-source file infection tool for lab experiments

When to avoid

  • you need active development or support - new features are sponsor-only and pull requests are ignored
  • you want a defensive or malware-analysis tool rather than an offensive one
  • you need ARM ELF support or modern platform guarantees - support is limited and aging
