Ad Fraud

Dns stack would be my easiest way to do it or like the way that I'd probably start if I had to choose. Almost every ad fraud investigation that we've looked into at least some portion of their traffic were compromised devices. And so a lot of what this impression demand comes back to is Who has access to compromised devices? Or who has code that could be inserted into an online auction to dynamically compromise devices and all of the above are basically used by these malicious networks.
