What is WebRTC, how to disable and avoid data leakage in popular browsers

What is WebRTC and why is it dangerous

WebRTC is a feature in your browser that streams audio and video data over the network. It can be used to create video conferences without the help of Zoom or Skype.

But more often this technology does more harm than good. A minimal number of people use it for its intended purpose, and everyone else can become victims of hackers and data leaks via WebRTC. It saves your IP address and accesses your microphone and camera - all this data is in an open network, which scammers can use.

Therefore, we recommend disabling WebRTC on your devices. Let's see how to do this in known browsers.

Video: What is WebRTC and how to turn it off and disable it in different browsers
