What this decoy is

Medium-interaction SSH/Telnet honeypot widely used for interactive session and malware-download telemetry.

For CTI analysts

  • Rich post-auth command transcripts and downloaded malware samples (when enabled) support actor TTPs and tooling intel.
  • SFTP/SCP may appear as SSH subsystems — UHBS grades SSH/Telnet plugins, not a separate SFTP protocol.

Primary signals: SSH/Telnet sessions, commands, downloaded artifacts, auth events.

For blue teams / detection engineering

  • Classic blue-team sensor: alert on successful auth to decoy creds and on outbound download behavior from the honeypot.
  • Keep Cowrie isolated; downloaded malware must not reach production file shares.

Trust & limitations

  • Evaluation proof under UHBS 4.2.2 — not a certification or endorsement.
  • Prefer full/ over quick/ for decisions.
