How to check if sites are using WebRTC

The term RTC is a shortcut to Real-Time Communications, a set of APIs supported by all major web browsers. The primary use of this application is to integrate better communication capabilities into the browser that sites and services can use for voice and video chat and communication models WebRTC is enabled by default in Firefox, Chrome, and other browsers, and may be used by websites and services without user intervention.

The WebRTC feature is one of these new technologies which on the one hand are very useful and on the other side is a privacy nightmare and can be misused, and one of the issues with WebRTC from a privacy standpoint is that browsers may leak the "real" IP address of the device to websites, Because there are no WebRTC permission requests, sites may do so without users knowing them, and users who connect to a VPN, Socks proxy, or Tor Tor, their device's IP address may have been leaked automatically because of this, which is a huge privacy issue that is ignored. Most often by browser makers.

Check whether the sites are using WebRTC
If you use Google Chrome or most Chromium-based browsers like Opera or Vivaldi, type chrome: // webrtc-internals in the browser's address bar to list all WebRTC connections. As we see, the site that tried to establish the WebRTC connection is listed in Above and in this case https://ip.voidsec.com/.

Mozilla Firefox users need to type the webrtc command in the browser's address bar to display WebRTC connections, and Firefox lists the URL under session statistics.

However, the fact that a WebRTC connection is included in the browser does not necessarily mean that the IP address of the device is leaked, and you can use internal pages to see if sites are using or misusing WebRTC, and although you expect to use WebRTC on sites that provide services and communication applications, It's hard to find a reason why the news site may want to do the same.

In conclusion, if you ask me, I will say that browsers should never implement features that may leak data such as IP address without requiring users to get permission first, and to meet other useful posts.
