Avast SecureLine VPN: Resolving IP leak related to WebRTC
WebRTC is a feature that supports B2B applications such as voice calling, video chat, and P2P file sharing without any need for plugins. There is an issue with WebRTC affecting Windows, Mac OS X and Android systems that allows the IP address to be discovered in browsers which apply WebRTC (such as Google Chrome and Mozilla Firefox). A website could potentially exploit WebRTC, making your actual IP address visible even when connected to a VPN such as Avast SecureLine.
We are actively looking for a solution to fix this issue. However, you can still protect your privacy in the meantime by blocking or disabling WebRTC. Or, avoid the vulnerability by using a browser which does not apply WebRTC (such as Safari or Internet Explorer).
Please note that when WebRTC is disabled some peer connections may not be possible. For example, a video chat or file sharing application which depends on WebRTC functionality.
The procedure to disable WebRTC varies:
Microsoft Internet Explorer does not currently enable WebRTC by default, so no action is required for this browser unless you have manually enabled WebRTC.
Mac OS X
Safari does not currently enable WebRTC by default, so no action is required for this browser unless you have manually enabled WebRTC.
In Google Chrome for Android, you can manually block WebRTC using a Chrome Flag (experimental setting):
chrome://flags/#disable-webrtc in the address bar and press Enter.
- Press Enable. This in fact disables the WebRTC feature.
- Reboot your phone.
Please be aware that Chrome Flags are subject to change or disappear at any time.
