Detect phishing and fraud signals in a URL by deep structural analysis — punycode/IDN homograph attacks (mixed Latin/Cyrillic), embedded credentials (user:pass@host trick), high-risk TLDs, double-encoding and control-character smuggling, subdomain brand deception, and numeric/IP host obfuscation. Static analysis only, no network. Complements the URL Validator (which does basic protocol/IP checks).
