MyDoom Sequel Has A Twist
Jan. 28, 2004
A new variant of the Internet worm is poised to launch a denial-of-service attack on Microsoft's Web site.
By George V. Hulme

Antivirus and Internet security firms are warning of a new variant to the MyDoom worm, and this time the author has it wired to not only launch a denial-of-service attack against SCO Group Inc.'s Web site on Super Bowl Sunday, but against Microsoft.com as well.

The new variant, known as MyDoom.B, began to appear late Tuesday. Its threat level was raised by many antivirus companies from low risk to medium risk by Wednesday afternoon.

While MyDoom.B is similar to the earlier version--aside from its adding Microsoft to its denial-of-service list--it also attempts to block users from being able to access 65 Web sites run by antivirus and security companies, security firm iDefense Inc. says in an advisory.

IDefense's advisory also theorizes that the new version may be using computers infected with MyDoom.A to help itself spread.

The trend of virus writers tweaking viruses and worms to quickly produce new, more-destructive variants is gaining momentum. In the fall, the MiMail.c worm wreaked havoc on Internet users; it was largely based on the MiMail worm that appeared in August. And the Sobig worm, ranked before MyDoom as the most virulent Internet worm ever, packed a nasty one-two punch against computer systems in August and September.
