Prevent IP Address Leaks At Google Chrome And Mozilla Firefox
Another security issue was brought to light thanks to recent customer reports. The problem lies in potential revealing user’s local and public IP address to websites even though VPN is in use. It is caused by the WebRTC protocol implementation in browsers that was developed to help establish connection between browsers and surpass the need for additional plugins. The term ‘RTC’ stands for Real-Time-Communication, as it helps create video and audio chat applications, yet it allows to discover actual local IP address due to security leak in the browser. The same issue also exists in Adobe Flash or Oracle Java browser plugins. So, if you ever browse on PC or Mac, or Android device, this post might be useful for you.
Run a Test
If you are using VPN Unlimited or any other client on your device, you can check if your system is vulnerable by running a test for WebRTC local IP leak available here. Keep in mind that not only Windows users, but also Mac OS X, Android users who use Google Chrome, and Mozilla Firefox browsers are also affected.
More on WebRTC Danger
Customers’ reports and recent research have shown new security vulnerability affecting Chrome and Firefox web browsers. Now, websites can perform a new form of IP check, which allows them to identify user’s actual ISP issued IP address even if they are using VPN! How is it done?
One of the main goals of the VPN is to protect user’s IP by issuing a random one, even of another country. Many security experts agree that the problem is not in the flaw itself (as this issue is just a consequence of the new communication protocol) but in the fact that millions of users will go without knowing about it. We suggest you take a moment to check your system, run a test and fix it.
Fix WebRTC Security Hole
Let’s find out how you can secure the WebRTC holes in your browsers:
Google Chrome. Disable WebRTC support with this extension https://chrome.google.com/webstore/detail/webrtc-block/nphkkbaidamjmhfanlpblblcadhfbkdm?hl=en
