Click Injection

Click Injection is a deceptive form of mobile ad fraud that manipulates attribution systems by firing fraudulent clicks at precise moments to claim credit for app installs or conversions.

Definition

Click Injection refers to a sophisticated ad fraud tactic predominantly seen in mobile advertising, where malicious software or an embedded app detects when a new application is being installed and immediately generates a fake click just before the installation completes. This timing-based manipulation tricks attribution platforms into assigning credit and associated payouts to the fraudster instead of the legitimate source. It is particularly prevalent in cost-per-install (CPI) and performance marketing campaigns, where attribution timing is critical for billing and analytics. Click injection not only misattributes conversions but also distorts campaign performance data and drains advertising budgets. This technique often exploits system-level install broadcasts on Android devices to operate effectively.
