Google has actively been rooting out apps that engages in malicious behaviour ranging from ad fraud to seeding harmful code from the Play Store. However, despite its relentlessness, some malware loaded apps keeps surfacing from time to time and are booted off the app repository after raking in a tonne of downloads. The recent one now is CamScanner, the app that turns your phone into a scanner for intelligent document management. The app has been weeded out after discovering that it was spreading malware.
CamScanner was actually a legitimate app, with no malicious intentions whatsoever, for quite some time. It used ads for monetization and even allowed in-app purchases. That however changed later.
For example, an app with this malicious code may show intrusive ads and sign users up for paid subscriptions.
The app has been installed by 100 million users and had 1.8 million reviews, most of which were positive. However, a recent influx of negative reviews pointed to problems with the app’s user experience which prompted Kaspersky to investigate the software.
If you have the app installed on your smartphone, check to see if you notice any unheard off behavior otherwise uninstall it or download the latest version that doesn’t contain malicious code depending on your devices.
