MuonFP is an enterprise-ready passive TCP fingerprinter.
It identifies and classifies network traffic from TCP packet characteristics, helping security professionals detect reconnaissance activity such as port scanning.
This is free and open source software.
Key Features
- Generates TCP fingerprints from packet attributes including TCP options, window sizes, MSS, and window scale.
- Focuses on the SYN and SYN-ACK handshake stages.
- Helps identify scanning and reconnaissance activity.
- Outputs fingerprints in JSON single-line delimited format.
- Supports rotating logging with configurable paths and file size limits.
- Can convert legacy TCP fingerprint data such as p0f signatures.
- Integrates with firewall tooling for blocking traffic based on fingerprints.
- Written in Rust with no external dependency on Wireshark or similar tools.
