OpenCanary
Open source multi-protocol daemon honeypot from the Thinkst Canary project.
Technical Architecture & Overview
OpenCanary is a Python daemon that runs modular honeypot services, including SSH, SMB, HTTP, FTP, MySQL, and portscan sensors, and logs interactions to files, syslog, or the Thinkst console. Each daemon presents a credible low-interaction version of the service it imitates. It pairs naturally with Canarytokens for file-based tripwires.
Targeted Technical Use Cases
Self-managed decoy services on internal network segments without commercial licensing.
Evaluation & Trade-offs
Core Strengths
- +Many protocol modules in one lightweight daemon.
- +Open source and easy to script across hosts.
- +Same vendor lineage as the commercial Canary platform.
Trade-Offs & Limitations
- -Low interaction only; deep attacker engagement needs high-interaction honeypots.
- -Console integration is optional and partially tied to the commercial product.
Defensive Security Application
Detecting scanning and lateral movement on internal segments through service decoys.
