New Trojan that buys you apps | Android Portal

What you did not know about the new Trojan that buys you apps from the Play Store


Security researchers recently discovered a new Trojan virus named Skyfin that attacks the Android system. The function of this new malware is to infiltrate in the local Android Play Store app to then download or buy apps without you noticing.

Up until now, Skyfin has been seen only as a secondary download on phones infected by other Trojans in the Android.DownLoader family. This is a series of Trojans that have been spread through malicious applications, distributed primarily by third-party app stores (similar to the Play Store, but not official stores).

Last month this new Trojan was discovered in the firmware of a low-end Android device. It highlights the fact that this malware can download and use exploits that reach the root of the device, allowing Android.DownLoader and its entire range of Trojans to perform any operation with your computer.

Trojan licensed to download and buy apps in the Play Store

This Trojan is a fairly aggressive intruder because it has the ability to download applications without the user’s authorization, and you can also buy them. According to reliable sources, such as Dr. Web (a Russian security agency), Skyfin is the main Trojan that is usually installed when downloading applications from unofficial stores.

While Android.DownLoader downloads other apps, Skyifin specializes in entering the Play Store, as this Trojan was designed to commit its misdeeds within Google’s official application store, something that Android.DownLoader cannot do.

With Skyfin on your Android device, this can include reviews, do store searches, buy or download apps, and more.

According to Dr. Web, this trojan downloads the applications and stores them on your local SD card and then install them. Apparently those who run this Trojan generate profits with the amount of installations of other applications.

After Google removed these applications from the Play Store, Skyfin infections transmitted a command to their server to get a new list of apps to install. So far, Google has not talked about it, however, you need to be aware with applications that are installed from external sources to the Play Store.
