Technical Description

Android package file
The Trojan may arrive as the following APK package:
APK: criptomovel.apk
Name: Android Security Suite Premium


When the Trojan is being installed, it requests permissions to perform the following actions:

  • Access information about networks.
  • Access information about the WiFi state.
  • Add a system service.
  • Broadcast an SMS receipt notification.
  • Broadcast sticky intents.
  • Broadcast a WAP PUSH receipt notification.
  • Modify the current configuration.
  • Change network connectivity state.
  • Allow access to low-level power management.
  • Disable the keyguard.
  • Open windows that are for use by parts of the system user interface.
  • Open network connections.
  • Change the phone state, such as powering it on and off.
  • Monitor, modify, or end outgoing calls.
  • Check the phone's current state.
  • Read SMS messages on the device.
  • Start once the device has finished booting.
  • Monitor incoming SMS messages.
  • Change the Z-order of tasks.
  • Send SMS messages.
  • Open, close, or disable the status bar and its icons.

When the Trojan is executed, it displays an "Activation Code", which is generated from the device ID.

Next, the Trojan steals SMS messages and posts them to the following location:

A remote attacker may then send a command to the compromised device to perform the following actions:
  • Disable the application
  • Enable the application
  • Uninstall itself
  • Send the phone number of the remote attacker
  • Change the phone number of the remote attacker in the device's Contacts
  • Sends system information to the remote attacker, such as device model, device manufacturer, OS version, bank account activation code, and current version of the Trojan


Symantec Security Response encourages all users and administrators to adhere to the following basic security "best practices":

  • Use a firewall to block all incoming connections from the Internet to services that should not be publicly available. By default, you should deny all incoming connections and only allow services you explicitly want to offer to the outside world.
  • Enforce a password policy. Complex passwords make it difficult to crack password files on compromised computers. This helps to prevent or limit damage when a computer is compromised.
  • Ensure that programs and users of the computer use the lowest level of privileges necessary to complete a task. When prompted for a root or UAC password, ensure that the program asking for administration-level access is a legitimate application.
  • Disable AutoPlay to prevent the automatic launching of executable files on network and removable drives, and disconnect the drives when not required. If write access is not required, enable read-only mode if the option is available.
  • Turn off file sharing if not needed. If file sharing is required, use ACLs and password protection to limit access. Disable anonymous access to shared folders. Grant access only to user accounts with strong passwords to folders that must be shared.
  • Turn off and remove unnecessary services. By default, many operating systems install auxiliary services that are not critical. These services are avenues of attack. If they are removed, threats have less avenues of attack.
  • If a threat exploits one or more network services, disable, or block access to, those services until a patch is applied.
  • Always keep your patch levels up-to-date, especially on computers that host public services and are accessible through the firewall, such as HTTP, FTP, mail, and DNS services.
  • Configure your email server to block or remove email that contains file attachments that are commonly used to spread threats, such as .vbs, .bat, .exe, .pif and .scr files.
  • Isolate compromised computers quickly to prevent threats from spreading further. Perform a forensic analysis and restore the computers using trusted media.
  • Train employees not to open attachments unless they are expecting them. Also, do not execute software that is downloaded from the Internet unless it has been scanned for viruses. Simply visiting a compromised Web site can cause infection if certain browser vulnerabilities are not patched.
  • If Bluetooth is not required for mobile devices, it should be turned off. If you require its use, ensure that the device's visibility is set to "Hidden" so that it cannot be scanned by other Bluetooth devices. If device pairing must be used, ensure that all devices are set to "Unauthorized", requiring authorization for each connection request. Do not accept applications that are unsigned or sent from unknown sources.
