WPAD Man in the Middle (Clear Text Passwords)

This blog-style tutorial describes a practical credential-harvesting technique that abuses Internet Explorer's "Automatically detect proxy settings" behavior and name resolution fallbacks (DNS/WINS/LLMNR) to serve a malicious wpad.dat and capture clear-text HTTP basic-auth credentials using the Responder tool; the post includes installation and usage examples, captured credential output, and remediation advice (add a WPAD DNS entry or disable autodetect proxy settings via Group Policy).
