New Android Apps in the Play Store Contain Malware

In the recent, write up by Dr.Web on virus activity on mobile devices he mentioned that he has discovered many malicious apps.

“Over the month, Doctor Web’s malware analysts discovered dozens of malicious apps on Google Play. Among them were adware trojans, fake apps used by scammers, info-stealers targeting confidential data, and others.”

30 applications with almost 10 million users have been found on the Google Play Store distributing adware.

“All of them were built into various programs, including image-editing software, virtual keyboards, system tools and utilities, calling apps, wallpaper collection apps, and others.” Said Dr.web

“To display ads, some of them request permission to show windows over other apps; the rest ask users to add them to the exclusion list of the battery-saving feature. In addition, to make it more difficult for users to detect malicious apps in the future, the trojans hide their icons from the list of installed apps in the home screen menu—or, they replace the icons with less noticeable ones. Take, for example, the icon named “SIM Toolkit”, which when selected, launches an eponymous system app for working with SIM cards—instead of the original app.”

Google has removed most of the applications, but some remains available for download and installation via the Play Store. If any was installed before their removal from the Play Store, you will still need to uninstall them from your device manually and run an Anti-Virus scan to clean any remnants.

Users should be caution when downloading apps from Google Play or otherwise, and refrain from granting extensive permissions to apps.
