Dangerous Android VPNs are lurking on the Google Play Store. Here are the safe ones that are on sale.

More and more people are turning to VPN apps to boost their privacy and security on their Android devices. Far less, however, realize the potential risk of downloading the wrong one.

Google's latest fraud advisory alert has sounded the alarm about the rising threats of malicious VPN and warned that some dodgy VPNs could be spyware in disguise – and it's far from the first time this year these risks have been identified.

In August, it was revealed that fraudulent adtech group VexTrio were behind some VPN apps and, in the same month, security researchers revealed that a popular free Chrome VPN extension was actively spying on its 100k+ users.
