It appears that systems using a given graphics driver can have the same WebGL fingerprint on hardware with a given GPU. In NoScript options, check “Forbid WebGL” in the “Embeddings” tab. In Firefox, for example, open “about:config” and toggle “webgl.disabled” to “true”. When using VPN services, I recommend blocking WebGL. On a given system, it appears that all browsers with WebGL enabled will have the same WebGL fingerprint. WebGL uses the GPU via the OS graphics driver. WebGL fingerprinting and IPv6 leaks are far worse. A recent W3C draft guidance states: “elimination of the capability of browser fingerprinting by a determined adversary through solely technical means that are widely deployed is implausible”. Any adversary that learned your browser’s fingerprints could later identify you, even if you were connecting through a VPN and/or Tor, as long as you were using the same browser. And so sites that you use in testing may see the same browser fingerprints from both your ISP-assigned IP address and your VPN exit IP address. Browsers can be fingerprinted in various ways. But there is some risk in testing for VPN leaks. The only way to know whether all traffic is using the VPN tunnel is through testing. Risks from Browser Fingerprinting and IPv6 Leaks

The VPN tunnel adapter is utun0 in macOS, and wg0 or tun0 in Linux. In macOS and Linux, open a terminal, and run ifconfig. The IPv4 Address will be something like 172.x.y.z or 10.x.y.z. You’ll see an ethernet adapter section with the Description “WireGuard Tunnel” or “TAP-Windows Adapter V9”. In Windows, open a command prompt, and run ipconfig /all. But how can you ensure that all of your traffic is routed through the VPN tunnel? And even if everything seems OK now, what will happen if the machine sleeps, and then resumes? What if there’s an interruption in network connectivity? Or what if you’re using Wi-Fi, and switch to a new access point and network? Or if you connect to a network that’s fully IPv6 capable? This guide demonstrates how you can conduct a comprehensive VPN leak test.įirst, verify that your computer has configured a VPN tunnel. It runs, and there are no error messages.
