Bahama Botnet Stealing Traffic From Google 52
itwbennett writes "'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 DNS poisoning,' explains Juan Carlos Perez in an ITworld article. '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. It's not clear where the Canadian server gets these results. What is evident is that the results aren't 'organic' direct links to their destinations, but are instead masked cost-per-click (CPC) ads that get routed through other ad networks or parked domains, some of which are in on the scam and some of which aren't.' 'Regardless, CPC fees are generated, advertisers pay, and click fraud has occurred,' Click Forensics reported on Thursday in a blog posting."
