Shocking Findings in the VPN World!

A recent peer-reviewed study has thrown a spotlight on 18 of the most downloaded virtual private network (VPN) apps from the Google Play Store, uncovering that these seemingly independent services are all interconnected in three major groups. With a staggering 700 million downloads collectively, these apps are not only popular—they're potentially putting users' data at risk!

Published in the prestigious journal of the Privacy Enhancing Technologies Symposium (PETS), the study reveals that these VPNs are failing to transparently disclose their interconnectedness, which is alarming enough. But it doesn’t stop there; they share infrastructure that harbors serious security vulnerabilities.

Big Names, Bigger Problems!

Among the VPNs implicated are well-known names like Turbo VPN, VPN Proxy Master, and X-VPN. These apps have been exposed as vulnerable to attacks that can compromise users' browsing activity and lead to the injection of corrupted data. This is a major red flag for anyone relying on these services for online privacy!

The Research Behind the Discovery!

Titled "Hidden Links: Analyzing Secret Families of VPN apps," the study was inspired by an earlier investigation from VPN Pro. They identified multiple apps sold by VPN companies that weren’t revealing their ties to one another, prompting the researchers to systematically document these secret relationships.

Using a comprehensive approach, the researchers scrutinized the business documents, web presence, and underlying code of the top downloaded VPN applications. Through their analysis, they grouped the 18 implicated VPNs into three main families.

The Threats Lurking Behind the Connections!

**Family A**: This group includes Turbo VPN, Turbo VPN Lite, and several others, linked to three providers associated with Qihoo 360, a company flagged by the US Department of Defense as having military ties in China.

**Family B**: Comprising services like Global VPN and Super Z VPN, these eight apps operate under five different providers but share the same IP addresses, raising serious red flags about privacy.

**Family C**: In this pair, X-VPN and Fast Potato VPN display eerily similar code and protocols, despite differing providers, suggesting more interconnectedness than users might realize.

Why You Should Be Worried!

For VPN users, this study highlights two crucial issues. Firstly, many of these companies are misleading users about their true ownership and affiliations. Trust is paramount when it comes to privacy—if a VPN can’t be honest, how can users be secure?

Secondly, these apps are riddled with flaws. All 18 VPNs rely on the Shadowsocks protocol with a hard-coded password, making them vulnerable to server-side takeovers and client-side eavesdropping. This means your online activities could be up for grabs!

A Call to Action!

The findings of the "Hidden Links" study serve as a stark reminder that app stores aren’t an infallible safeguard against dangers lurking in free VPNs. Users should thoroughly vet any free VPN apps before downloading and consider using those that offer paid subscriptions for better security, like Proton VPN. Stay informed and prioritize your online safety!
