August Was Worst Month Ever For Viruses, Worms
Not surprisingly, the Sobig.F worm topped the company's "Dirty Dozen" list, accounting for 76.8 percent of confirmed infections. Adding to Sobig.F's standout nature was the sheer number of e-mails the worm generated. At the height of its spread, Sobig was responsible for 73 percent of all e-mail traffic, Central Command said.
Persistent, earlier versions of Sobig also showed on the chart, but they were responsible for only 1.5 percent of confirmed infections.
The Blaster worm (Lovsan.A) came in second, tallying 6.4 percent of confirmed infections.
