cowrie v2.0.2 releases: Cowrie SSH/Telnet Honeypot
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.
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 stored in an UML Compatible format for easy replay with original timings
- 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
