Researching the spam economy

An amazing experiment to map the spam economy – by hijacking 75,000 computers in Storm Worm’s botnet! Surprisingly, researchers estimate that spam campaigns still earn a profit, even at a response rate less than 1 in 107!

Researchers Hijack Storm Worm to Track Profits

A single response from 12 million e-mails is all it takes for spammers to turn annual profits of millions of dollars promoting knockoff pharmaceuticals, according to an unprecedented new study on the economics of spam.

The research team estimates that about three-quarters of all e-mail sent by the Storm worm was snagged by junk e-mail filters, ISP blacklists, and other e-mail security applications.

“Under the assumption that our measurements are representative over time, we can extrapolate that… Storm-generated pharmaceutical spam would produce roughly $3.5 million dollars of revenue a year,” the team concluded.

“By the same logic, we estimate that Storm self-propagation campaigns can produce between 3,500 and 8,500 new bots per day.”
