BDFProxy is a man-in-the-middle proxy that patches downloaded binaries on the fly by embedding payloads, combining the Backdoor Factory with mitmproxy. It is a security research and penetration testing tool for demonstrating the risk of binaries served over unencrypted HTTP.

Use cases

• patch binaries during download via man-in-the-middle attack
• embed payloads into executables as they are downloaded over HTTP
• demonstrate risks of software distributed without TLS
• strip digital signatures from Windows PE binaries during transfer
• run a red team exercise injecting backdoors into downloaded tools
• test network defenses against MITM binary tampering

When to choose

• you are a security professional demonstrating MITM binary patching attacks
• you need to patch PE or ELF binaries on the fly during a pentest
• you run Kali Linux and want an integrated binary backdooring proxy
• you are researching how unsigned binaries can be tampered with in transit

When to avoid

• you need a maintained tool - the public version is old and the new version is sponsor-only
• you require modern mitmproxy compatibility - it only works with mitmproxy 0.11-0.17
• you want a general-purpose HTTP proxy without offensive capabilities
• you need a tool for defensive monitoring rather than attack simulation
