There are only a handful of browsers that contain an option of blocking WebRTC IP leaks. Given that permission prompts are not displayed by WebRTC, it is possible that websites access the IP address without the knowledge or consent of the user. In all major browsers including Chrome and Firefox, WebRTC is enabled by default and websites or services utilize it without interacting with the user.Īs far as privacy aspect is concerned, the issue with WebRTC is that browsers can leak the real IP address of the device to any website. The basic purpose of using WebRTC is to improve the browser’s communicational capabilities, which is important since a variety of communication forms like voice or voice chat are used by websites/services. However, it believed to be a privacy nightmare now since it can be abused easily. It is a set of APIs used by all main web browsers. WebRTC (RTC = Real-Time Communications) emerged as pretty useful technology but its dark side only got revealed much later. It is quite unfortunate that such a grave flaw has been ignored by browser makers for so long. It is believed to be one of the most critical issues that have been identified so far as a user’s real home IP address gets exposed to websites. VPN service leaking real IP addresses through WebRTC leak This means, if you are connected to a VPN, Tor or Socks proxy, it is a possibility that the device’s IP address is being leaked automatically. As per the findings of Stagno, nearly 23% of VPN providers are still leaking IP addresses of users through the VPN flaw dubbed as WebRTC Leak. Paolo Stagno, an Italian security researcher using the online moniker VoidSec, has revealed a startling new discovery about virtual private networks or VPNs.
