WebRTC IP Leaks Explained: Why Disabling the Protocol Harms Anonymity in Anti-Detect Browsers

The article from Aurorium details how WebRTC technology can leak real IP addresses even when users route traffic through proxies. It explains the peer-to-peer mechanics of WebRTC, the role of STUN servers in generating ICE candidates, and why standard TCP proxies fail to handle UDP traffic. Disabling WebRTC via flags or JavaScript extensions creates detectable anomalies that anti-fraud systems flag as non-standard environments. The recommended approach involves native emulation inside the browser kernel so that STUN requests return proxy IPs while preserving full API integrity across workers. Additional leaks through local network addresses, mDNS candidates, and IPv6 are also covered with practical verification methods using tools like BrowserLeaks and CreepJS.
