Brief Description 

    

RBackdoor is a Trojan with no dangerous effects as the only actions it carries out are the following: it opens and uses communication ports (initially port 4820) and assigns a password to communications.

 

When RBackdoor reaches a computer, it goes memory resident and waits for a Telnet connection -or a connection carried out with a similar program- to be established with the apropriate password through the port the Trojan opened.

 

It is easy to become infected by RBackdoor as it can reach a computer through several means of transmission: e-mail messages carrying infected documents, computer networks, CD-ROMs, Internet downloads, FTP, floppy disks, etc.
