LLMNR Poisoning Lab

Lab Type: LLMNR & NBNS Spoofing (Responder Tool)

Goal: Capture NTLMv2 hashes using LLMNR misconfigurations

Tools Involved: Responder, Wireshark, Hashcat (optional)

What You’ll Learn: Real-world techniques for lateral movement, password capture, and why legacy protocols still haunt corporate networks in 2025.

This is a controlled virtual lab designed for ethical hacking and security research education. Students will simulate attacks against a misconfigured host that still allows LLMNR broadcasts—something that should be disabled in any secure environment.

Use this opportunity to understand how attackers harvest credentials using Responder and witness firsthand why tools like SMB signing and disabling LLMNR are non-negotiable in modern networks.
