Attack of the Zombie Computers Is a Growing Threat, Experts Say

Although there is a wide range of estimates of the overall infection rate, the scale and the power of the botnet programs have clearly become immense. David Dagon, a Georgia Institute of Technology researcher who is a co-founder of Damballa, a start-up company focusing on controlling botnets, said the consensus among scientists is that botnet programs are present on about 11 percent of the more than 650 million computers attached to the Internet.

[…] “It’s a huge scientific, policy, and ultimately social crisis, and no one is taking any responsibility for addressing it,” said K. C. Claffy , a veteran Internet researcher at the San Diego Supercomputer Center.

The $6 billion computer security industry offers a growing array of products and services that are targeted at network operators, corporations and individual computer users. Yet the industry has a poor track record so far in combating the plague, according to computer security researchers.

“This is a little bit like airlines advertising how infrequently they crash into mountains,” said Mr. Dagon, the Georgia Tech researcher.
