BiDi Swap: Bidirectional Text Trick Makes Fake URLs Look Real
🔍 Varonis Threat Labs highlights BiDi Swap, a technique that exploits Unicode bidirectional rendering to make malicious URLs appear legitimate. By mixing Right-to-Left and Left-to-Right scripts, attackers can visually move parameters, paths, or subdomains into the apparent host name to facilitate phishing and spoofing. Browser defenses vary — some highlight domains or flag lookalikes while others leave gaps — so the report urges user caution and vendor improvements.
