MyDoom spawns more potent variant

Thursday, 29 January 2004, 12:34 AM EST

A new, nastier variant of the MyDoom worm has been released and is beginning to spread across the Internet, according to antivirus experts.

Computers infected with MyDoom.B will launch a 12-day denial-of-service attack on Microsoft.com beginning Feb. 1. They will also launch a separate attack on the SCO Group's website on the same date, just as the original version of the worm is coded to do.

MyDoom.B also alters system files in order to block infected computers from accessing a list of 65 websites, most of them belonging to antivirus vendors, in an apparent attempt to stymie users attempting to download antivirus application updates or information.

The worm's predecessor swept through inboxes earlier this week and was quickly dubbed the most virulent e-mail worm of all time by e-mail-filtering company MessageLabs.
