Brief Description 

    

Bck/FraggleRock.20 is a backdoor Trojan that makes it possible to access another computer remotely by means of a client-server connection. This Trojan is written in Visual Basic 6 and it consists of three files: a client, a server and a configuration program.

Visible Symptoms

  • Controlling the keyboard and mouse.
  • Restarting the system or shutting it down.
  • Opening the CD-Rom tray automatically.
  • Enabling and disabling the task bar.
  • Dialing a phone number by using the modem installed on the affected system.
  • Printing documents.

The configuration program looks as follows:
