Both apps requested to record audio, allowing the app to use the microphone to listen in to anything said near the device at anytime, as well as a number of permissions that allow the app to be persistent on the device. The VPN apps Hotspot VPN, Free VPN Master, Secure VPN, and Security Master by Cheetah Mobile must too be removed. All those apps were proved to be involved in ads fraud. While adware is often more of an annoyance than anything else, the intrusive adverts can cause issues for users as the ads constantly run in the background, repeatedly interrupting use.
Such apps came with a number of additional permissions that suggest that could be used for more intrusive behaviour if desired.They also drain phone battery. Google removed them for the Play Store. “It’s not the first time we’ve seen bad apps make it onto an official app store. Unfortunately, the vetting carried out by these official stores is largely focused on user experience,” Dan Cuddeford, director of sales engineering at Wandera told media. Dangerous apps are still available for install on Google’s official store. There’s no substitute for common sense and treating apps from unknown sources as potential threats.
