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
