More than 300 Android apps, installed over 60 million times, were part of an ad fraud campaign that displayed unwanted ads and attempted to steal sensitive data.
The apps mimicked utility apps such as QR scanners, expense tracking apps, health apps, and wallpaper apps.
Most of the affected apps were removed from the Google Play Store, but users who have already installed them remain at risk.
To stay safe, users are advised to remove any unwanted or unused apps and ensure they are running the latest version of Android.
