This malware was first found by Kaspersky researchers. The following is an excerpt from Kaspersky researchers blog post describing the malicious module:

“Kaspersky products detect this module as Trojan-Dropper.AndroidOS.Necro.n, which we have observed in some apps preinstalled on Chinese smartphones. As the name suggests, the module is a Trojan Dropper. That means the module extracts and runs another malicious module from an encrypted file included in the app’s resources. This “dropped” malware, in turn, is a Trojan Downloader that downloads more malicious modules depending on what its creators are up to at the moment.

For example, an app with this malicious code may show intrusive ads and sign users up for paid subscriptions.”

Why Play Store removed CamScanner?

Now the question is why Play Store removed CamScanner?- Kaspersky reported this issue to the Google and it was promptly taken off its Play Store. Some CamScanner app users had already spotted suspicious behavior and left reviews on the app’s Google Play page with warnings to avoid this app.

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. However, at some point, that changed, and recent versions of the app shipped with an advertising library containing a malicious module.

If you have already downloaded and installed this app, we would suggest you uninstall this app as soon as possible to keep your data from getting compromised.

CamScanner like Apps

If you still want to download a CamScanner like apps, you can download ‘CamScanner HD’ from the Play Store, but we wouldn’t trust the authenticity of the app. For now, the best options to scan and convert PDF documents are Adobe Scan, Microsoft Office Lens or even the in-built scanning functionality of the Google Drive app.
