Many different web applications utilize WebRTC technology in order to not require additional software or plugins to function. A few of the software types using WebRTC are video conferencing apps, file transfer apps, chat software, as well as desktop-sharing apps. The WebRTC project is supported by Google, Mozilla, Opera, and Microsoft across all the major operating system platforms: Windows, Mac, Linux, iOS, and Android.
So, What Exactly is a WebRTC IP Leak and Why is it Bad?
Simply put – because WebRTC relies on peer-to-peer protocol connections it can reveal your true external IPv4 or IPv6 IP address to the outside world, even while tunneling through a VPN! Looks at the box below – if you see any IP addresses listed, then your browser currently has WebRTC enabled.
Even though WebRTC can be blocked via add-ons and extensions such as uBlock Origin and NoScripts, it’s generally a good idea to manually block this protocol, if possible, just to be sure.
Here’s a list of WebRTC supported Web-Browsers and how to disable WebRTC if possible:
