Ad Fraud

Digital advertising pays publishers and partners for measurable events: an ad shown (impression), an ad clicked, an app installed, or a conversion completed. Ad fraud manufactures those events artificially so the fraudster collects payment for activity that involved no real, interested human. Because the entire supply chain runs on automated measurement, fake events that mimic real ones are difficult to distinguish at scale.

On the impression and click side, fraudsters run bots that load pages and ads to rack up billable events, stack or stuff ads into invisible or stacked slots so many impressions register from a single view, and operate domain-spoofing schemes that misrepresent low-quality inventory as premium sites. Botnets of compromised devices and farms of low-cost devices generate traffic that looks geographically and behaviorally diverse.

On the performance side, attackers target attribution. Install fraud floods app installs from emulators or device farms, and attribution fraud steals credit for organic installs through click injection and click spamming, firing fake clicks so a fraudster's network is credited for conversions it did not drive. Across all of these, the common tactic is to hide automation behind residential proxies, spoofed device identifiers, and reset or randomized environments so each fake event appears to come from a distinct genuine user.
