Download CamScanner App which is available on both Android and iOS. The ‘Phone PDF Creator’ or ‘Scanner to Scan PDFs’ app had over 100 million downloads, before being booted from the Google Play Store. Researchers at Kaspersky Labs found malware in the recent versions of the popular OCR (optical character recognition) App. It was apparently harboring an advertising library containing a malicious module that the Kaspersky researchers identified as ‘Trojan-Dropper. AndroidOS.Necro.n.’
For example, an app with this malicious code may show intrusive ads and sign users up for paid subscriptions. Some users of the CamScanner App have already spotted suspicious behavior and left reviews on the app’s Google Play Store page with warnings to avoid the app. Kaspersky labs researchers examined the recent version of the app and found the malicious module there. We reported our findings to Google, and the CamScanner app was promptly removed from the Google Play Store.
As per the report, this particular malware module was previously spotted in a few apps that came preinstalled on some Chinese smartphones. The malware module was spotted only on the Android version of the app and it seems like its iOS version is still available on the App Store, probably because of Apple’s strict app vetting policies. As the Kaspersky blog notes, CamScanner was a pretty good app that offered notable functionality.
