MakeUseOf/MUD – “WebRTC (Web Real-Time Communication) is the browser technology that powers video calls, voice chat, and peer-to-peer file sharing directly in your browser, without needing a separate app or plugin. Google Meet, Discord in-browser, file transfer tools, and basically anything that connects to other devices — all of them depend on it. It sounds excellent, and it is, but for a long period, your VPN was probably interacting with it completely wrong and leaking your IP address without alerting you. You wouldn’t really get a warning or notification, but your carefully planned privacy plan could be undone just because of a network interface issue. So, it’s time to make sure this browser API isn’t doing you dirty and leaking your data without you knowing, and whether you’re secretly telling everyone your business…Now, obviously, most VPNs and browsers have realized that leaking your IP address like this wasn’t ideal. That’s why this problem has mostly been addressed across all major browsers, with varying levels of protection, and some handy extensions if you want more protection. The easiest option is to just test it out yourself with a WebRTC leak test. There are several options available to you here; Browser Leaks and Surfshark are the easiest options. Head over to Browser Leaks and check out your IP address. Then enable your VPN, run the same test, and check the WebRTC Leak Test field to see if you’re still secure. For example, some browsers, like Brave and Firefox, give you the option to completely disable WebRTC, while others, like Safari, restrict how WebRTC works. But others, like Chrome and Edge, don’t provide a specific toggle or flag to work with, which is why you need a browser extension to stop your IP address from being leaked (check them out in the next section). I was actually surprised when I ran the tests, because it backed up other information I’d read online. Namely, that the tests aren’t always the most accurate, either…”
