Wayne Haber, director of development at SecureWorks, told SCMagazineUS.comtoday that many of the attacks targeted web browsers, meaning they could beattempts to enlarge botnets.

“What we tend to see with browser attacks is that they’retrying to create more bots for the botnets,” he said. “We’ve been researchingand trying to see why [there are increasing targets against utilities], and itmight be that they have a large number of workstations, which would make theminteresting to people creating botnets.”
