Virtual Private Network apps are quite useful for encrypting your web traffic or hiding your identity online, but research has found that over 38% of Android VPN apps contain malware that tracks users. The research group studied 234 VPN apps on the Google Play Store, the results?
18% do not encrypt traffic
84% leak user data
38% reveal malware or malvertising
80% request access to sensitive data like user accounts or text messages
The only thing to worry about is that most of these apps are highly rated and FREE.
The researchers also compiled a list of the top 10 ones you should avoid. (FYI: Google has taken down some these apps).
sFly Network Booster
One Click VPN (4.3 rating; 1 million downloads)
Fast Secure Payment OkVpn (4.2 rating)
Betternet (4.3 rating; 5 million downloads)
I would recommend you look into TunnelBear, but it is not 100% free and has been available for a long time. Opera’s VPN is also worth a try.
