Which tool detects rogue hosts running Responder on public Wi-Fi networks?

• A. got-responded
• B. Ophcrack
• C. pwdump7
• D. Respounder

Answer: (A)

Detecting rogue Responder activity hinges on spotting the tool’s characteristic behavior: listening for and responding to name-resolution requests (LLMNR, NBT-NS, MDNS) in a way that tries to harvest credentials. got-responded is designed to monitor the network and flag when a host on the LAN answers to these name-resolution queries in a Responder-like manner, producing indicators such as a Got-Responded event. On public Wi‑Fi, where devices of unknown trust may be present, this direct detection of Responder’s activity helps security teams identify a rogue host quickly and take action.

The other options don’t fit this purpose. Ophcrack is a password cracker that attempts to recover Windows passwords from hashes, not to detect Responder activity. pwdump7 extracts password hashes from a Windows system, again not for detection on the network. Respounder isn’t a standard tool known for detecting Responder activity on networks, so it wouldn’t reliably identify rogue Responder hosts.
