A group of Russian cybercriminals is stealing between $3 and $5 million a day by diverting legitimate advertising revenues from over 6,000 brand-name websites. The criminals do this by using legitimate data centers to run hundreds of servers pretending to be real people watching hundreds of millions of video ads a day. The scam is a new take on traditional click fraud, where the scammers install malware on home computers that watches the ads, and set up dummy websites stuffed with ads to collect the ad revenues.”]
