Coldframe is a low-interaction honeypot that impersonates supermarket refrigeration controllers, the kind hit by recent attacks on European stores. It mimics a Danfoss AK-SM 800A or a Copeland/Dixell XWEB supervisor, with optional fake Modbus temperatures, and logs every login, command and known-exploit attempt as JSON lines, tagged by CVE. It never runs commands or forwards traffic. One Python file, standard library only. MIT.
