The marketer’s field guide to mobile ad fraud

Mobile ad fraud is a pervasive issue in online advertising, costing billions annually.
It falls into two main categories: attribution hijacking, where fraudsters steal credit for real user installs via fake clicks (e.g., install hijacking, click flooding), and fake installs, which generate entirely fake user journeys using bots, device farms, or SDK hacking.
Fraudsters are sophisticated, operating like legitimate businesses, and constantly adapt to detection methods.
The impact extends beyond direct financial loss to polluted data, wasted resources, and ecosystem damage.
High-risk verticals include finance, travel, and shopping, with Android experiencing over 6x higher fraud rates than iOS.
Prevention requires a combination of secure infrastructure, real-time and post-attribution detection, and industry education.
As fraud evolves, continuous vigilance is necessary to protect marketing budgets.
