Technical details
This Trojan program is designed to provide remote management of systems running UNIX-type operating systems. It is a Perl scenario. It is approximately 12KB in size.

Payload
This Trojan has two parts, a server and a client. The execution depends on the parameters with which the Trojan is launched.
The server part opens a port which is specified in the body of the Trojan. The Trojan waits for a connection to this port and attempts to use the command line interpreter to run all commands received from the remote client.
The client is a shell for sending commands to the server part and for getting service messages.

Removal instructions
If your computer does not have an up-to-date antivirus, or does not have an antivirus solution at all, follow the instructions below to delete the malicious program:

  1. Delete the original Trojan file (the location will depend on how the program originally penetrated the victim machine).
  2. Update your antivirus databases and perform a full scan of the computer (download a trial version of Kaspersky Anti-Virus).
