A massive malvertising network has been infecting as many as 1 million computers per day with a variety of geo-focused banking trojans.
Named AdGholas, researchers say that it has been operating since 2015, infecting thousands of victims every day using a sophisticated combination of techniques that include filtering and steganography. It was receiving high-quality traffic from a variety of high rank referrers, from more than twenty different AdAgency/AdExchange platforms. The result was that AdGholas was clocking one to five million hits every day, and of these, 10-20% were redirected to an exploit kit.
