The Storm worm has grown into an online siege 10 times larger than any
other e-mail attack in the last two years, amassing a botnet of nearly
2 million computers, with worrying implications, researchers say.
Before Storm, an average day saw about 1 million virus-laden e-mails
crossing the Internet, says Adam Swidler, senior manager of software
security firm Postini. On July 24, researchers tracked 46.2 million
malicious messages, more than 99% of them from the Storm worm.
The number of zombie computers the Storm worm authors have amassed has
skyrocketed in the past two months, says SecureWorks senior researcher
Joe Stewart. From the first of January to the end of May, there were
2,815 bots launching Storm attacks. By the end of July, that number had
leaped to 1.7 million. "It's been building with exponential growth,"
says Stewart. "It's one of the largest botnets I've ever heard of."
