Cowrie - SSH/Telnet Honeypot

Cowrie is a medium interaction SSH and Telnet honeypot designed to log brute force attacks and the shell interaction performed by the attacker.

Features
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 cat files 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

Requirements
Software required:

• Python 2.7+, (Python 3 not yet supported due to Twisted dependencies)
• python-virtualenv

For Python dependencies, see requirements.txt
