Welcome to the Cowrie GitHub repository
This is the official repository for the Cowrie SSH and Telnet Honeypot effort.
What is Cowrie
Cowrie is a medium interaction SSH and Telnet honeypot designed to log brute force attacks and the shell interaction performed by the attacker.
Cowrie is developed by Michel Oosterhof.
You can join the Cowrie community at the following Slack workspace
Some interesting features:
- 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
catfiles such as
/etc/passwd. Only minimal file contents are included
- Session logs are stored in an UML Compatible format for easy replay with original timings with the
- Cowrie saves files downloaded with wget/curl or uploaded with SFTP and scp for later inspection
Additional functionality over standard kippo:
- 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)
- Logging in JSON format for easy processing in log management solutions
- Many, many additional commands
Docker versions are available.
- Get the Dockerfile directly at https://github.com/cowrie/docker-cowrie
- Run from Docker Hub with:
docker pull cowrie/cowrie
- Python 2.7+, (Limited Python 3 support available for SSH only)
For Python dependencies, see requirements.txt
Files of interest:
cowrie.cfg- Cowrie's configuration file. Default values can be found in
data/fs.pickle- fake filesystem
data/userdb.txt- credentials allowed or disallowed to access the honeypot
dl/- files transferred from the attacker to the honeypot are stored here
honeyfs/- file contents for the fake filesystem - feel free to copy a real system here or use
honeyfs/etc/issue.net- pre-login banner
honeyfs/etc/motd- post-login banner
log/cowrie.json- transaction output in JSON format
log/cowrie.log- log/debug output
log/tty/*.log- session logs
txtcmds/- file contents for the fake commands
bin/createfs- used to create the fake filesystem
bin/playlog- utility to replay session logs
Is it secure?
Maybe. See FAQ
