Fraud detection company DoubleVerify says it’s found a new video fraudscheme in which scammers are reselling standard banner ad impressions as video plays.
The worst part?
They’re selling as many as 120 videos ads for every single banner ad.
First, the scammers buy a banner ad slot on an ad exchange. Then they turn around and rebroker that space. But instead of selling it once, they fill that one slot with as many as eight video players. And they then sell as many as fifteen different video ads for each of the eight players.
