As 2007 comes to a end , Once we look back the worm that has hit the Internet worst was the Storm Worm, who made its debut in the January of 2007. Its name came from a widely circulated email about the kyrill weather storm in Europe, and its subject was “230 dead as storm batters Europe.” The virus first hit on January 19th, and three days later , the virus infected 8 percent of the machines .
The Worm’s work :
If your computer is infected by the Storm Worm, your machine becomes a part of a large botnet. The botnet acted to perform automated tasks that ranged from gathering data on the host machine, to DDOSing websites, to sending infected emails to others. As of September of this year, an estimated 1 million to 10 million computers were still part of this botnet, and each of these computers was infected by one of the 1.2 billion emails sent from the infected hosts.
Storm Worm is a difficult worm to track down because the botnet is decentralized and the computers that are part of the botnet are consistently being updated with the fast flux DNS technique. Consequently, it has been difficult for infected machines to be isolated and cleaned.
