The Simple Telnet Honeypot Server offers cybersecurity professionals and enthusiasts a straightforward tool for capturing and analyzing Telnet-based interactions. This Python-scripted server, built upon the Twisted network programming framework, simulates a Telnet server to log unauthorized access attempts and helps in identifying potential security breaches.

• Low-Interaction Honeypot: Simulates a Telnet server to safely log authentication attempts without high risk.
• Configurable Settings: The host and port settings can be easily modified using command-line arguments.
• Extensive Logging: Every interaction, including login credentials, is recorded for in-depth security auditing.
• Interactive Response Simulation: Mimics a live Telnet service, providing automated responses to capture more detailed information.
• Educational Resource: Great for learning about Telnet service vulnerabilities and network security monitoring.

• Python 3.x
• Twisted Python library

Begin by cloning the repository or downloading the telnet.py script. Make sure Python and Twisted are installed on your system.

git clone https://github.com/0xNslabs/telnet-honeypot.git
cd telnet-honeypot
pip install twisted

Start the server with the following command, specifying host and port if needed. By default, it binds to all interfaces (0.0.0.0) on port 2323.

python3 telnet.py --host 0.0.0.0 --port 2323

Interaction logs are saved in telnet_honeypot.log, which contains detailed records of all Telnet commands and login attempts.
