Virtual Private Networks (VPNs) are legal and increasingly popular for individuals wanting to circumvent censorship, avoid mass surveillance or access geographically limited services like Netflix and BBC iPlayer. Used by around 20 per cent of European internet users they encrypt users' internet communications, making it more difficult for people to monitor their activities.
The study of fourteen popular VPN providers found that eleven of them leaked information about the user because of a vulnerability known as 'IPv6 leakage'. The leaked information ranged from the websites a user is accessing to the actual content of user communications, for example comments being posted on forums. Interactions with websites running HTTPS encryption, which includes financial transactions, were not leaked.
The leakage occurs because network operators are increasingly deploying a new version of the protocol used to run the Internet called IPv6. IPv6 replaces the previous IPv4, but many VPNs only protect user's IPv4 traffic. The researchers tested their ideas by choosing fourteen of the most famous VPN providers and connecting various devices to a WiFi access point which was designed to mimic the attacks hackers might use.
