New MyDoom Email Virus Spreads Quickly: "The sheer amount of traffic generated by the virus has already brought down many networks, and some security experts now believe that attackers originally launched the virus as a Denial of Service (DoS) attack on SCO Group, the UNIX copyright holder that's now suing various Linux companies for copyright infringement. However, this attack is having the most dramatic effect on end users, many of whom are still surprisingly uninformed when it comes to the dangers of opening attachments.

Second, the virus places a backdoor on their systems that attackers can later exploit."
