Trojan.Ploutus.3

Added to the Dr.Web virus database: 2013-12-17

Virus description added:

A malicious program designed to infect ATMs of one international manufacturer. It is distributed in Latin America and is supposedly installed on the system from a bootable CD.

It consists of the following components:

  • NCRWMI.exe—an executable file written in Delphi and installed on the system as the NCRDRVP system service. It downloads the SystemP.dll library.
  • SystemP.dll—a library written in Delphi. Operating as a sniffer, this library analyzes the whole bulk of IP traffic looking for incoming commands.

    screen

    The library supports the execution of the following commands:
    • 5449610000583686=xxxxxxxxxxxxxxxx—run the Trojan’s executable file with the xxxxxxxxxxxxxxxx parameter (C:\WINDOWS\system32\cmd.exe /c PLOUTOS.EXE 5449610000583686=xxxxxxxxxxxxxxxx).
    • 6037428100036810—kill the Ploutos.exe process (C:\WINDOWS\system32\cmd.exe /C START TASKKILL /F /IM Ploutos.exe).

    The 5449610000583686=xxxxxxxxxxxxxxxx command can be written on the magnetic strip of a card in the Track 2 section.

  • Ploutos.exe—a Trojan’s executable file that controls the infected ATM. It saves its configuration data in the config.ini file to the current folder. The log is saved to the Log.txt file. To perform some of its functions, the Trojan utilizes the ActiveXFSControls.dll dynamic library from the ATM’s SDK.

Parameters the Trojan receives look as follows:

5449610000583686=0123456789abcdYZ, where YZ—command, 0123456789abcd—parameters.

The main module can execute the following commands:

  • 5449610000583686=2836957412536985—generate the ID (4 random numbers) and enter the value into the DATAA parameter of the configuration file.
  • 5449610000583686=0123456789abcd54—activate the Trojan for 24 hours. The key is calculated using the following method:

    screen

    The operation time is added to the DATAB parameter of the configuration file. The activation key’s md5 value is entered into the DATAC parameter. The3d1905b7 value is taken from the command line as the key.
  • 5449610000583686=0123456789abcd31—command to withdraw cash (the number of 40 is hard coded in the Trojan’s body).

    screen

    This command is executed if a correct ID is specified via the command line (the a28c value is used).
  • 5449610000583686=0123456789abcd32—command to terminate the Trojan’s process. It is executed if a correct ID is specified via the command line (the a28c value is used).
  • 5449610000583686=0123456789abcd99—command to kill the Trojan’s process (cmd.exe /C TASKKILL /F /IM Ploutos.exe).

The ATM is controlled using XFSVendorModeServiceClass from the ActiveXFSControls.dll library, which is included in the device’s software.

The cash withdrawal routine is implemented as follows:

Curing recommendations

  1. If the operating system (OS) can be loaded (either normally or in safe mode), download Dr.Web Security Space and run a full scan of your computer and removable media you use. More about Dr.Web Security Space.
  2. If you cannot boot the OS, change the BIOS settings to boot your system from a CD or USB drive. Download the image of the emergency system repair disk Dr.Web® LiveDisk , mount it on a USB drive or burn it to a CD/DVD. After booting up with this media, run a full scan and cure all the detected threats.
Download Dr.Web

Download by serial number

Use Dr.Web Anti-virus for macOS to run a full scan of your Mac.

After booting up, run a full scan of all disk partitions with Dr.Web Anti-virus for Linux.

Download Dr.Web

Download by serial number

  1. If the mobile device is operating normally, download and install Dr.Web for Android. 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 for Android 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.
