MyDoom.C Slams Into Microsoft.com

A new version of the MyDoom worm was discovered Monday as it created a widespread distributed denial of service (DDOS) attack against Microsoft Corp.'s Web site.

According to an initial analysis of the worm by security intelligence firm iDefense, the new version of the worm does not contain the usual e-mail and peer-to-peer distribution mechanisms, but rather spreads to existing MyDoom.A systems through the network backdoor available on those systems.


The worm launches a denial-of-service attack against Microsoft.com by that domain name. Performance monitoring by Netcraft indicates that www.microsoft.com was unavailable through the early hours of Monday, Feb. 9, probably due to the attack.

The new version has no kill date and fixes several known bugs in earlier MyDoom variants. Once installed, it sets itself up to load at startup.
