Malware in the shape of the Necro.n Trojan dropper snuck into one of the advertising modules and installed another Trojan tasked with downloading other muck onto the device - for example, advertising apps and programs taking out paid subscriptions to third-party services behind the user’s back. But that changed when a malicious advertising module was added to the app. Its developers derived income from advertising and paid features - nothing unusual so far. What went wrong? Well, up until a certain point, CamScanner was a normal app that simply carried out its stated functions.

Not only was the app available on Google Play, but according to the store it was installed by more than 100 million users. Recently, our researchers detected malicious code in the CamScanner app for digitizing documents. Here are some of the most striking incidents. So from time to time, malicious apps do slip in. However, Google Play receives such a vast number of new apps and updates of existing ones that it is simply not possible for the moderators to keep track of everything. If they find a violation, they ban the program from the store. Before they publish an app, moderators check it for compliance with an extensive list of requirements. It is no mean feat for malware to get into Google Play. How Google monitors the security of Android apps It is true, however, that you’ll find fewer of them in the official store than on third-party sites, and they get removed on a regular basis. But that doesn’t mean there are no viruses in the Google Play.

We always recommend downloading Android apps from official stores and nowhere else.
