Cowrie SSH/Telnet Honeypot ToolCowrie is a medium to high interaction SSH and Telnet honeypot designed to log brute force attacks and the shell interaction performed by the attacker. In medium interaction mode (shell) it emulates a UNIX system in Python, in high interaction mode (proxy) it functions as an SSH and telnet proxy to observe attacker behavior to another system.
FeaturesChoose to run as an emulated shell (default):
- Fake filesystem with the ability to add/remove files. A full fake filesystem resembling a Debian 5.0 installation is included
- Possibility of adding fake file contents so the attacker can cat files such as /etc/passwd. Only minimal file contents are included
- Cowrie saves files downloaded with wget/curl or uploaded with SFTP and scp for later inspection
- Run as a pure telnet and ssh proxy with monitoring
- Or let Cowrie manage a pool of Qemu emualted servers to provide the systems to login to
For both settings:
- Session logs are stored in an UML Compatible format for easy replay with the bin/playlog utility.
- SFTP and SCP support for file upload
- Support for SSH exec commands
- Logging of direct-tcp connection attempts (ssh proxying)
- Forward SMTP connections to SMTP Honeypot (e.g. mailoney)
- JSON logging for easy processing in log management solutions
Docker versions are available.
- To get started quickly and give Cowrie a try, run:
docker run -p 2222:2222 cowrie/cowrie
ssh -p 2222 [email protected]
On Docker Hub: https://hub.docker.com/r/cowrie/cowrie
Or get the Dockerfile directly at https://github.com/cowrie/docker-cowrie
- Python 3.5+ (Python 2.7 support will be deprecated end of 2019)
For Python dependencies, see requirements.txt.

Data SharingCowrie will by default upload data on crashes and Python exceptions to api.cowrie.org. This information is used to improve the honeypot and is not shared with third parties. It can be disabled by setting enabled=false in [output_crashreporter].
