Bahama Botnet Stealing Traffic from Google

The Bahama botnet, a sophisticated network of compromised computers that is wreaking click-fraud havoc among advertisers, is also snatching away Web traffic and revenue right from under the nose of mighty Google. As part of its design, the Bahama botnet not only turns ordinary, legitimate PCs into click-fraud perpetrators that dilute the effectiveness of ad campaigns. It also modifies the way these PCs locate certain Web sites through a malicious practice called DNS poisoning. In the case of Google.com, compromised machines take their users to a fake page hosted in Canada that looks just like the real Google page and even returns results for queries entered into its search box
