IDN Homograph Detection

Phase 8intelligenceN/A

Description

Generates Unicode confusable variants (Cyrillic, Greek, accented) of the domain and encodes them as Punycode ACE labels. Each is checked via Google DNS-over-HTTPS and crt.sh for active TLS certificates not issued to the real domain.

Security Impact

IDN homograph attacks exploit visually identical Unicode characters to impersonate trusted domains in browsers, email clients, and chat applications. TLS cert presence elevates a variant from suspicious to confirmed threat.
