Homoglyph attacks (also called IDN homograph attacks) exploit visual similarity between characters from different scripts to create deceptive domain names.
Attackers may register domains like "pаypal.com" (with Cyrillic 'а') that look identical to "paypal.com" in browsers, tricking users into visiting malicious sites.
Protection: Always verify URLs carefully, enable punycode display in your browser, use security tools that detect homoglyph domains, and implement URL validation in your applications.
A Cyrillic а and a Latin a render as pixel-identical characters in most fonts but are completely different code points to a computer, which is exactly what makes "аpple.com" with that Cyrillic а an entirely different domain from the real apple.com despite looking indistinguishable at a glance, a well-known phishing technique called an IDN homograph attack. This tool scans domain names and identifiers for suspicious script mixing and known lookalike character substitutions, flagging exactly which character doesn't belong before a spoofed domain gets mistaken for a real one.

Useful for checking whether a suspicious-looking domain actually contains a lookalike character from a different script, auditing a list of identifiers for a homoglyph substitution hiding in plain sight, or verifying a domain is genuinely what it appears to be before trusting a link that looks correct.
