A Trojan for Android that is incorporated into various software published on Google Play and other application stores.

Android.SockBot.1 starts operating either once it is launched or once the system is booted. To launch itself, the Trojan monitors the system event android.intent.action.BOOT_COMPLETED.

Then, depending on a version of the Trojan, Android.SockBot.1 connects to the command and control (C&C) server 136.243.***.159 or dfm.*** If successful, it sends the string “HELLO\n”. The C&C server replies with the following instructions:

  • “HELLO” – replies with “HELLO”
  • “PING” – replies with “PONG”
  • "SLEEP” – pause the operation for two minutes
  • "WAIT” – pause the operation for two seconds
  • “CREATE,ip,port” – connect to the client, using the IP address and a network port specified in the command. The Trojan then can use an infected device as a proxy server to pass a network traffic through it. The proxy server applies the SOCKS protocol.

Curing recommendations


  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.
