What is Respounder?
Respounder is a network security tool that detects the presence of a Responder LLMNR/NBT-NS poisoner in the network. It sends LLMNR name resolution requests for non-existent hostnames, forcing a malicious responder to reveal itself and helping identify compromised machines before attackers can steal hashes.
Security professionals, network administrators, and penetration testers who need to detect LLMNR/NBT-NS poisoning attacks in corporate or public networks.
It provides a simple, cross-platform command-line tool for early detection of Responder attacks, with JSON output for easy integration into monitoring systems and no external dependencies.
