Cowrie

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

Cowrie is directly based on Kippo by Upi Tamminen (desaster).

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)
• Logging in JSON format for easy processing in log management solutions
• Many, many additional commands

Requirements

Software required:

• An operating system (tested on Debian, CentOS, FreeBSD and Windows 7)
• Python 2.7+
• Twisted 8.0+
• python-crypto
• python-pyasn1
• python-gmpy2 (recommended)
• Zope Interface 3.6.0+

Files of interest:

• cowrie.cfg - Cowrie's configuration file. Default values can be found in cowrie.cfg.dist
• 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 utils/fsctl.py
• 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
• utils/createfs.py - used to create the fake filesystem
• utils/playlog.py - utility to replay session logs

Is it secure?

Maybe. See FAQ

I have some questions!
