Brief Description 

    

Morb is a worm without destructive payload. It uses e-mail, IRC chat channels and the kaZaA P2P file sharing application to spread extremely rapidly.

Once Morb has infected the computer, it replies to all the messages in the Inbox.

In addition, it opens a communications port and sends a message to all the users connected to the same IRC channel as the infected user. This would allow other users to access the affected computer remotely.

Visible Symptoms 

    

Morb is difficult to identify at first sight, as it does not display any other messages on the screen.
