Brute Force SSH & Build a Honeypot Now (Hydra and Cowrie Demo)
Big thank you to Cisco for sponsoring this video and sponsoring my trip to Cisco Live San Diego.
This video features David Bombal and Kyle Winters demonstrating practical
cybersecurity techniques. Kyle walks through how to use Hydra to brute force SSH passwords, explaining the process of leveraging wordlists and optimizing the attack. Following the offensive demonstration, Kyle transitions into defensive measures, showing viewers how to quickly and easily set up an SSH honeypot using Cowrie. The honeypot serves as a decoy to attract and monitor malicious actors attempting to access a network. The demonstration includes setting up the honeypot on an Ubuntu host, configuring IP tables for port redirection, and monitoring logs for incoming connection attempts. The video highlights the importance of understanding both attack methods and defensive strategies in cybersecurity. Kyle also mentions free ethical hacking training resources available through Cisco Networking Academy (netacad.com) and future tutorials on Cisco U (u.cisco.com).
