Later in the month, Doctor Web’s experts identified on Google Play other Android.FakeApp family Trojans which were added to the Dr.Web virus database as Android.FakeApp.138, Android.FakeApp.139, and Android.FakeApp.144. They were hidden in applications that allegedly paid people to participate in polls. When launched, the malware loaded fraudulent websites where potential victims were asked to answer a few questions. After that, in order to receive a “reward”, the user was required to pay a fee for a wire transfer, currency conversion, or any other procedure named by the attackers. If the owner of an affected mobile device agreed to pay, the requested amount was transferred to the pockets of cybercriminals, while the fraud victim got nothing.

In addition, attackers distributed the Trojan downloader Android.DownLoader.832.origin under the guise of various utilities. It downloaded and tried to install other malicious applications.

Google Play remains the most secure Android app resource. However, cybercriminals are still managing to use it to distribute malicious software. To protect their Android mobile devices, users are recommend to install Dr.Web for Android antivirus products.
