Some of the world’s biggest brands were ripped off by a digital fraud scheme that used a network of websites connected to US advertising industry insiders to steal what experts say could be millions of dollars, a BuzzFeed News investigation has found.
 
 Approximately 40 websites used special code that triggered an avalanche of fraudulent views of video ads from companies such as P&G, Unilever, Hershey’s, Johnson & Johnson, Ford, and MGM, according to data gathered by ad fraud investigation firm Social Puncher in collaboration with BuzzFeed News. Over 100 brands saw their ads fraudulently displayed on the sites, and roughly 50 brands appeared multiple times.
