Girls can save the world. A little girl from Prague has helped security researchers discover and flag seven scam apps on the Google Play Store and the Apple App Store. These apps had been downloaded over 2.4 million times and the creators of these malicious scam apps had earned more than $500,000 (that’s ₹3.7 crore approx) before being pulled down, as per SensorTower reports. These seven apps were adware scams that appeared as wallpaper, music or entertainment apps.

Avast looked into the apps and revealed that these aggressively displayed ads and charged users anything between $2 to $10 to remove them. The apps provided simple games that “just causes the device to vibrate, wallpapers or music” said Avast. Some of the apps were HiddenAds trojans that disguised itself as a safe application but served intrusive ads instead. 

These ads were served outside the app and the original app icon was hidden so users would fail to figure out where the ads were coming from. Hidden icons also meant that these apps are hard to spot and uninstall, also these apps would show ads even when they were not being used.

Once the security researchers were alerted, They notified both Apple and Google. Google has removed the apps already, Apple is yet to respond though, according to reports.
