An analysis of the technologies used by cybercriminals allows us to draw conclusions about the virus industry’s possible vectors of development and more effectively confront future threats. You, too, can learn what actions various malicious programs take in infected systems and how to withstand them.
A family of Android Trojans, which are built in system applications disguised as firmware update code for mobile devices. These malicious programs do have the specified function, but in some cases, cyberciminals embed Android.FakeUpdates into system software that does not participate in the operating system update. For example, in the SystemUI application, which is used to run the interface of the Android OS.
The Trojans of this family also run lua scripts and stored in application resources, in which malicious programs Android.FakeUpdates are built in. In addition, Trojans are able to download new lua scripts from a remote server. These scripts can perform various actions: for example, transfer the user's phone number to a remote server and also download, install and delete applications.
According to statistics, every fifth program for Android contains a vulnerability (or, in other words, a "loophole") that lets cybercriminals successfully introduce Trojans onto mobile devices and manipulate them into doing whatever actions they need them to.
