Beyond the VPN: How WebRTC Exposes Your Real IP Address

WebRTC, a critical browser API for real-time communication, contains a significant privacy vulnerability that can expose your actual IP address even when behind a VPN. This leak occurs through the STUN protocol during ICE candidate gathering, which bypasses VPN tunnels on many systems and can be exploited by fingerprinting services. Understanding how to detect and test for these leaks is essential for users concerned about privacy and developers building security-aware applications.
