W32/Prestige

Virus categories : Worm
Repairable?: Yes
First appeared : 12/10/2002
'In The Wild': No

Basic description : W32/Prestige is a worm that is easy to recognize because it refers to the sinking of Prestige, an oil tanker off the Spanish coast.

It spreads rapidly using the following means of transmission:

E-mail messages with the subject fotos INEDITAS del PRESTIGE en el fondo del Atlantico, which includes an attached file called PRESTIGE.ZIP.
By automatically sending itself via IRC.
The message text entices the user to open the PRESTIGE.ZIP file by claiming that it contains some pictures of the Prestige oil tanker. When the file is opened, however, a window is displayed, which informs the user that a plug-in must be installed to display the pictures. If the user clicks on the Yes button an error message is displayed.

W32/Prestige is not considered dangerous, as its only aim is to spread to other computers. However mass mailing of this virus could cause infected e-mail accounts and IRC chat channels to collapse.
