Brief Description 

    

Olorin is a worm programmed to spread via IRC in a file that seems to be a screen saver, whose extension is always SRC.

However, when this file is run, Olorin makes the necessary modifications to send itself out to other users via chat. It also displays a message on screen.

Visible Symptoms 

    

It is not easy to know if Olorin has reached your computer, as the only indication is a file with an SRC extension attached to an e-mail message.

When the user saves the file to a directory, it can be noticed that its icon contains the image of a mouse.

When the file is run, the following window is displayed on screen:

If the user clicks on OK, Olorin carries out the necessary actions to send itself out to other users via IRC.
