LLMNR Protocol

Attack

python /usr/share/responder/Responder.py -I eth0 -rdw -v

The responder is listening for events related to protocols LLNMR, NBT-NS, and DNS/MDNS. It also spins up many services to attract targets, for example, HTTP, WPAd, SMB, SQL, LDAP, RDP, and so on.

Run responder in the morning and at lunchtime when users log on and log off. The responder is part of

Wait for responses, grab the NTLMNv2 hashes, and crack them using the
