The IDN/Punycode Phishing Detector is a specialized security tool designed to protect users and businesses from homograph attacks. It analyzes domains that use Internationalized Domain Names (IDN) and Punycode (starting with xn--) to mimic legitimate, high-traffic websites using look-alike Unicode characters. This tool decodes the Punycode, identifies mixed scripts, and highlights suspicious characters, helping you verify if a link is genuine or a sophisticated phishing attempt.
