Score: 6.3/10 (Innovation: 6, Technical: 6, Documentation: 8, Utility: 5)

Coldframe is a single-file Python honeypot that impersonates supermarket refrigeration controllers from Danfoss and Copeland/Dixell, mimicking their web fingerprints, login flows, and known CVEs. It logs attacker behavior and recognizes specific public exploits, providing a low-dependency, container-ready deception tool for ICS/OT security monitoring.

Target audience: security researchers, OT/ICS defenders, network administrators

Repository: https://github.com/hedgerow-dev/coldframe · Python · MIT
