Android App With 100M Downloads affected by Trojan Dropper Malware

Are you a user of CamScanner app?, the PDF creator and scanner on the phone available for Android and iOS with more than 100 million downloads. Here is bad news for you, the app has now been booted from the Android app store

According to the Kaspersky researchers who identified this issue, it has been harboring an advertising library containing a malicious module which was identified as "Trojan-Dropper.AndroidOS.Necro.n.".

Basically, the Trojan-Dropper malware found within the app was apparently extracting and running 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,” the Kaspersky blog notes.

It is to be noted that this malware affected only the Android App store, and the iOS app is still up and running on Apple's App Store.
