Description

A trojan application for devices running Android operating system. Its functionality includes URLs opening, downloading and launching other apps, as well as to load and display websites on-top of the other applications’ windows and the operating system UI.

Operating routine

Android.Mixi.42.origin represents a modification of the Android.Mixi.44.origin trojan and performs the same malicious actions. It implements a clicker functionality, covertly opening URLs received from the C&C server. In addition, it also loads and displays various websites on-top of other apps. The main difference between these two modifications is that the Android.Mixi.42.origin can download and run other applications without user notice. This trojan can be downloaded onto the Android devices by other malware.

To silently launch the downloaded apps, the Android.Mixi.42.origin calls the com.newcomb.ap.plink.GoPathMgr class which is absent in the trojan itself but present in another trojan of this family ― the Android.Mixi.36.origin. This particular malware launches APK files, using the Tool.SilentInstaller.7.origin tool that creates a virtual environment where apps can run without installation. Thus, if the Android.Mixi.42.origin is downloaded onto the Android device and launched by the Android.Mixi.36.origin, it will gain the access to this missing class and will be also able to run downloaded apps without user permission and notice.

Curing recommendations


Android

  1. If the mobile device is operating normally, download and install Dr.Web for Android Light. Run a full system scan and follow recommendations to neutralize the detected threats.
  2. If the mobile device has been locked by Android.Locker ransomware (the message on the screen tells you that you have broken some law or demands a set ransom amount; or you will see some other announcement that prevents you from using the handheld normally), do the following:
    • Load your smartphone or tablet in the safe mode (depending on the operating system version and specifications of the particular mobile device involved, this procedure can be performed in various ways; seek clarification from the user guide that was shipped with the device, or contact its manufacturer);
    • Once you have activated safe mode, install the Dr.Web для Android Light onto the infected handheld and run a full scan of the system; follow the steps recommended for neutralizing the threats that have been detected;
    • Switch off your device and turn it on as normal.
