cowrie v1.6.0 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.

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

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 bin/fsctl
  • 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
