What is a WebRTC leak and how to prevent it? This question is becoming more important as the days go on, as more and more people are discovering that they have this issue.
So far, there has been no definitive answer about what a WebRTC leak is. Some say it’s a security vulnerability, others say it’s a way for websites to track your activity.
However, one thing is for sure – it’s something you want to protect yourself from. In this article, I’ll explain what a WebRTC leak is, how to determine if you have it, and most importantly, how to fix it. Stay safe out there!
WebRTC Leak: What is WebRTC?
WebRTC is an open-source project that aims to provide a simple, standardized method for delivering real-time communications (RTC) via the Internet.
Shortly after the debut of Google Chrome, its development team observed that the Web’s infrastructure was inadequate for real-time communications.
There was no default implementation in any browser, much less a browser-wide standard, that enabled direct data transfers between individuals.
Google aimed to provide the essential requirements for seamless data transmission on a standardized platform, so removing the need for third-party applications or plug-ins.
Within a few years, Mozilla, Microsoft, Opera, and Apple all joined the project. What’s the first example that springs to mind when you consider video calling?
FaceTime, Skype, or even Join.me or GoToMeeting for business conferences? These are all instances of real-time communication, but they fall short of the WebRTC project’s objectives.
The first two are proprietary systems that necessitate the employment of identical technology on both ends: If you want to FaceTime with a buddy who does not own an Apple iPhone, you must locate an alternative platform.
When attending a video conference, you must be prepared in advance to verify that the software downloads properly and that your plug-ins are operational.
WebRTC arose from the requirement for technology that could unify real-time communications independent of device or browser, without requiring additional plug-ins or downloads.
What is a WebRTC Leak?
A WebRTC leak is the exposure of an end-IP user’s address, which poses a significant security risk.
WebRTC leaks occur while attempting to establish video or audio contact with another individual using a browser that employs WebRTC technology. Your browser then discloses your IP address; this is known as a leak.
As long as WebRTC is enabled in your browser and you’re on a page that employs it, your actual IP address will be accessible, and it will consequently be leaking. To prevent a WebRTC leak, you must disable WebRTC in your browser.
A WebRTC leak presents a risk to anybody who uses a VPN (a virtual private network) or just desires to maintain their online anonymity.
Having a VPN while utilizing WebRTC-enabled services somewhat contradicts the point of a VPN. The issue resides more with a browser than with a VPN; as you will find later, Safari is relatively secure about WebRTC leaks.
How to Disable WebRTC Using Extensions?
If your browser does not provide simple WebRTC deactivation, you will need to download a third-party addon. Here are two choices:
- WebRTC Network Limiter:
It is the most popular add-on for preventing WebRTC leaks for most browsers, including Chrome and Opera.
In addition, it merely disables the network characteristics responsible for the security vulnerability and does not stop WebRTC. That implies you can continue to use WebRTC-reliant technologies.
To block WebRTC leaks with uBlock, choose Options by right-clicking the extension’s icon. To prevent WebRTC from leaking local IP addresses, go to the Privacy section of the Settings tab and check the box next to Prevent WebRTC from leaking local IP addresses.
Note that browser add-ons may not prevent WebRTC leakage entirely. If you want complete privacy, you may need to switch to a browser that allows you to manually deactivate WebRTC.
How to Stop WebRTC Leaks on iOS?
WebRTC cannot be disabled on mobile Safari till iOS 11 or earlier. In iOS 12, the option to deactivate it was eliminated.
For iOS versions 12 and later, you may use the SurfShark iOS app to hide your true IP address and avoid WebRTC leaks.
Similar to the desktop version, disabling WebRTC on the Safari browser on iOS 11 or earlier is rather straightforward.
Step – 1: Launch the Settings app on your iOS device
Step – 2: Tap Safari > Advanced > Experimental Features after scrolling down.
Step – 3: Toggle the button beside Remove Legacy WebRTC API until it becomes green.
FAQs On WebRTC Leak
Should I turn off WebRTC in case of a leak?
WebRTC enables browser-based video and audio calls and file sharing on P2P systems. If you disable it, services such as Discord, Facebook Messenger, and Zoom may no longer function correctly on your browser. WebRTC should still be disabled if you want to prevent your IP address from leaking online. No one will be able to monitor your online activity if you take these steps and use a reliable VPN to conceal your IP address and safeguard your data. Good VPNs often provide applications for every operating system, including Android, iOS, Windows, macOS, and Linux.
How can I prevent a WebRTC leak?
You may avoid a WebRTC leak by deactivating WebRTC in your browser's settings or by installing a WebRTC-blocking extension.
What is a WebRTC leak test?
WebRTC may leak your IP address, making it accessible to the public internet. Using leak test tools, you may test for a leak by comparing your IP address while your VPN is enabled to when it is off. If you're worried about your online privacy, you may deactivate WebRTC in your browser and use a VPN to secure your connection.
What can WebRTC do?
WebRTC is an open-source initiative used by browsers to provide real-time video and audio communication over the Internet. WebRTC is used by almost every browser today since it is free and simple to deploy, but it poses a security concern because it exposes your IP address.
Why is WebRTC bad?
WebRTC is not inherently harmful, but it allows malicious actors to abuse user data; IP addresses may leak via the WebRTC interface.
How do I stop WebRTC from leaking in Chrome?
Google Chrome’s desktop version permits the installation of plugins that block Chrome WebRTC leaks. However, VPN extensions and services are more trustworthy and provide additional privacy protection. Android users are particularly appreciative of these services since they cannot apply leak that prevents extensions to the mobile version of Chrome and there is presently no method to directly disable WebRTC on mobile devices.
What is WebRTC used for?
WebRTC is an open-source tool that enables web-based video and audio communication. It improves audio and visual quality while decreasing lag time. WebRTC has the extra advantage of not requiring any additional software on your device.

Conclusion: WebRTC Leak
The WebRTC leak issue illustrates a crucial notion for people seeking enhanced online anonymity and security using a variety of privacy methods. Typically, the browser is the weakest link in the network.
Even if you are using a reliable VPN like SurfShark to conceal your IP address and location, the WebRTC problem demonstrates that there may be other risks in your privacy setup. (Until 2015, the WebRTC problem remained unknown to the public.)
Additionally, you should be wary of browser fingerprinting. This is when numerous browser and operating system settings and parameters may be utilized to generate a unique fingerprint and hence monitor and identify people.
Thankfully, there are also effective treatments for this issue. And last, there are other safe and private browsers to choose from, many of which may be tailored to your specific requirements.
