A complaint filed with the Federal Trade Commission (FTC) on Monday alleges that the popular free Virtual Private Network (VPN) service Hotspot Shield collects a large amount of data and intercepts user traffic.
Submitted by the Center for Democracy & Technology (CDT), the complaint (PDF) urges the FTC to investigate the data security and data sharing practices of Hotspot Shield, alleging they are “unfair and deceptive trade practices.” The complaint also claims the service engages into undisclosed data sharing and traffic redirection practices despite promising to protect the users’ privacy.
The organization also claims that “the VPN promises to connect advertisers to users who frequent websites in particular categories and while most VPNs prevent internet service providers from seeing a user’s internet traffic, that traffic is often visible in unencrypted form to Hotspot Shield. VPNs typically log data about user connections to help with troubleshooting technical issues, but Hotspot Shield uses this information to identify user locations and serve advertisements.”
Furthermore, the complaint alleges that Hotspot Shield insists it doesn’t make money from selling customer data, but that the service also promises to connect advertisers to users that frequently access travel, retail, business, and finance websites. CDT points out that these partners can link information about users’ web-viewing habits even if they are provided only with hashed or proxy IP addresses.
An analysis of Hotspot Shield’s functionality, data sharing, and network connections was performed by Carnegie Mellon University’s Mobile App Compliance System. Researchers downloaded and tested the Android app and found “undisclosed data sharing practices with third party advertising networks” when analyzing the application permissions.
They also discovered that the app discloses sensitive information such as names of wireless networks (via SSID/BSSID information), along with identifiers such as Media Access Control addresses, and device IMEI numbers.
“People often use VPNs because they do not trust the network they’re connected to, but they think less about whether they can trust the VPN service itself. For many internet users, it’s difficult to fully understand what VPNs are doing with their browsing data. Hotspot Shield tells customers that their privacy and security are ‘guaranteed’ but their actual practices starkly contradict this. They are sharing sensitive information with third party advertisers and exposing users’ data to leaks or outside attacks,” Michelle De Mooy, Director of CDT’s Privacy & Data Project, said.
