The MyDoom virus has had it's desired effect today, as the SCO site has been taken offline by what virus experts described as being a "spectacularly successful" attack.
SCO's worldwide director of Information Technology, Jeff Carlon, has been quoted as saying the following:
"This large scale attack, caused by the Mydoom computer virus that is estimated to have infected hundreds of thousands of computers around the world, is now overwhelming the Internet with requests to www.sco.com. While we expect this attack to continue throughout the next few weeks, we have a series of contingency plans to deal with this problem and we will begin communicating those plans on Monday morning."
F-Secure have stated that this is the largest single DDoS attack ever performed or recorded, and are estimating that over one million computers around the world have been infected.
Netcraft are also monitoring the SCO website.
It is also worth mentioning that no other internet sites appear to have been affected by this attack, including the Microsoft site which is the target of the MyDoom.b variant of the virus.
UPDATE: Riverhead could have saved the SCO website
UPDATE: SCO have actually removed the A Record for www.sco.com from their DNS servers in an effort to limit the attack.
