Researchers discovered two ad fraud rings called “Merry-Go-Round,” which redirect millions of online ads daily to shady websites. At its peak, the operation fed 782 million ads per day, but currently serves 200 million. Using complex techniques to evade detection, the fraudsters exploit flaws in online ad placement, causing substantial losses for companies. Vigilant partnership oversight can aid in fraud prevention.
