Do you trust Virtual Private Networks?


Virtual Private Networks (VPNs) turn out to be less private than you think, with Security researchers finding 23 per cent of VPN providers tested leak users’ IP address via WebRTC.  WebRTC is a commonly used free open-source project that has been applied in web browsers to allow real-time communication via JavaScript APIs. It’s used for example to implement browser-based chat apps. The privacy problems presented by WebRTC is not new and the issue has been known since at least 2015.

VPNs use the STUN (Session Traversal Utilities for NAT) server to translate between the VPN user’s local IP address and the public IP address.

STUN servers receive requests through the WebRTC which return the ‘hidden’ home IP-address as well as local network addresses for the system that is present. These requests aren’t usually evident because they aren’t part of standard XML/HTTP interaction, but they can be made via JavaScript. However, in many browsers – Brave, Chrome 9desktop and Android), Firefox, Samsung Internet Browser, Opera, Vivaldi – WebRTC and JavaScript are enabled by default.

Beside the WebRTC issue, those in the security business tend to frown on commercial VPN providers mainly because they don’t seem to always act in their customers’ interest. For example, some could log your activity, some track you to push ads your way, and some are just insecure.
