Google has removed CamScanner from the Play Store as it was discovered that through the app, malware was being spread on smart devices. The app had over 100 million downloads while it was still available on the Google Play Store.
Kaspersky reported that their researchers had found malware content in the application CamScanner — Phone PDF Creator. The app initially was a legitimate app with no harmful purpose that allowed users to photo scan documents to create PDFs. The app also had OCR capabilities that could covert images to text files. But at some point, the app started to update along with an advertising library that contained a malicious module.
The module was recognized as ‘Trojan-Dropper.AndroidOS.Necro.n’ which has been found in some apps that came preinstalled in Chinese smartphones. The malware is a Trojan Dropper which serves the purpose of installing another harmful software from an application’s encrypted files. The installed file is a Trojan Downloader that downloads more harmful modules on the device. The Trojan was not detected in the iOS version of the device.
Google Play Store is one of the safest platforms to download apps and software from so this might be a major concern for the company. But even Google Play Moderators who check each application are never able to complete their job given the volume of apps and amount of times these apps are updated. But lately, there have been many apps that have been found with malware content on the platform which led to removal of countless app.
With CamScanner removed from the Google Play Store, it is a good idea to back-up important documents stored within the app on your Android devices and you can use the photo-scanning feature on Google Drive to convert images to PDF.
