Web real-time communication (WebRTC) is an open-source feature in many web browsers and mobile applications that support real-time communication such as video and voice calling, data transfer, and other tasks without the need of any third-party plugin or apps installations. It simply allows the web browser to perform a fast peer-to-peer communication activity through application programming interfaces(APIs).
A WebRTC leak is when your public IP address is exposed via your web browser’s WebRTC functionality. The problem is that the WebRTC must obtain your public IP address and this reveals your device’s operation system, location and internet service provider. WebRTC identifies your real IP address by using Interactive Connectivity Establishment Protocol (ICE) and here are the two protocols and how they put your information at risk.
Most devices IP addresses usually are hidden from websites and STUN/TURN servers through firewalls. However, host candidate discovery can trick your browsers to expose IP addresses by reading them of your device.
STUN/TURN servers establish two functionalities in WebRTC: 1. It allows two or more devices to communicate with one another even behind the type of Network Address Translation (NAT) firewall. 2. It allows WebRTC to identify your IP address. This is the key reason why it can affect your privacy.
Common web browsers such as Google Chrome, Firefox, Opera and Microsoft Edge have WebRTC enabled by default. Therefore, those are most vulnerable to WebRTC leaks.
