Added to the Dr.Web virus database: 2015-04-11

Virus description added:

One of the Android.Toorch.1.origin components that encompasses the Trojan’s main malicious functionality. This component is a JAR file with the name libimpl.jar. Using the DexClassLoder class, it is loaded into the RAM. Once it is launched, it establishes a connection with the command and control server and receives from it the following configuration file:

<boolean name="android.library.libanalytics.action.self_update_last_is_success" 
value="true" />
<boolean name="android.library.libanalytics.action.upload_installed_apps_last_is_success" 
value="true" />
<boolean name="android.library.libanalytics.action.upload_device_info_last_is_success" 
value="true" />
<boolean name="android.library.libanalytics.action.upload_event_last_is_success" 
value="true" />
<boolean name="android.library.libanalytics.action.config_update_last_is_success" 
value="true" />

This Trojan’s component can execute the following actions:

  • Send the signal about its successful launch.
  • Download and install its own updates.
  • Send the server detailed information about the infected device (ID, device model and manufacturer, SDK version of the operating system, GPS coordinates, and other useful data).
  • Send the server the list of installed applications.
  • Stealthily download, install, and remove programs specified by cybercriminals.

    • 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.
