A lot of fuss for little trouble: Browser video chat renders VPN worthless, it says. Or: Firefox and Chrome reveal original IP address. Or: Deanonymisation via WebRTC. However: Turns out, very few are affected, because the vast majority operates behind a router and it is shielded by default – and even those, who actually are affected, can resolve the issue with little effort.
So, what’s this all about?
It’s about WebRTC, a video chat technique for real time communication directly inside modern browsers like Firefox and Chrome, which, as a side effect, can help to unveil a user’s original IP address, even though she or he is camouflaged by a VPN. Theoretically. In the real world the possible leak just affects users who are directly connected to the Internet with a modem. The WebRTC makes it possible to read all registered IP addresses inside the network card. All others should be safe, even though they use one of the mentioned browsers. From behind a router, all WebRTC is going to see will be in most cases a bunch of local IP addresses, such as 192.168.178.xxx and alike, which are common in all local networks and therefore worthless in terms of tracking.
If your browser is affected, can be tested very fast on the CyberGhost WebRTC IP detection page. Just open your browser and visit this page: WebRTC Real IP Detection.
If your real IP is exposed, start CyberGhost, clean your browser’s cache (by hitting ‘F5’) and visit the page again. If you’re unlucky and your IP is still exposed, install either the WebRTC Block plug-in for Chrome or the Disable WebRTC plug-in for Firefox.
