Storm Worm Botnet of 1.7M could create large DDoS attack
The massive Storm worm attack has built a botnet of 1.7 million computers -- large enough to unleash a highly damaging denial-of-service attack, researchers fear. As the Storm worm grows into a prolonged online siege 10 times larger than any other e-mail attack in the last two years -- amassing a botnet of nearly 2 million computers -- researchers worry about the damage hackers could wreak if they unleash a denial-of-service attack with it.
Between July 16 and Aug. 1, researchers at software security firm Postini have recorded 415 million spam e-mails luring users to malicious Web sites, according to Adam Swidler, a senior manager with Postini. Before the Storm worm began its attack, an average day sees about 1 million virus-laden e-mails crossing the Internet. On July 19, Postini recorded 48.6 million and on July 24, researchers tracked 46.2 million malicious messages -- more than 99% of them are from the Storm worm.
Joe Stewart, a senior security researcher at SecureWorks, noted that the number of zombie computers that the Storm worm authors have amassed as skyrocketed in the past month. From the first of January to the end of May, the security company noted that there were 2,815 bots launching the attacks. By the end of July, that number had leapt of 1.7 million. "It's really gotten enormous," said Stewart. "It's been building with exponential growth. It's one of the largest botnets I've ever heard of."
Storm Worm Erupts Into Worst Virus Attack In 2 Years
Storm worm authors are blasting the Internet with two types of attacks, and both are aimed at building up their botnet.
