Affiliate Hijacking

An affiliate marketing fraud tactic where malicious actors intercept or mimic tracking to wrongly claim commissions.

Definition

Affiliate Hijacking refers to a form of affiliate marketing abuse in which an unauthorized party manipulates referral tracking-such as intercepting links, redirecting traffic, or resurfacing tracking codes-to divert commissions that should go to legitimate affiliates. This tactic can involve replacing original affiliate links with fraudulent ones, running clone ads that siphon clicks and conversions, or exploiting browser extensions and scripts to capture the “last click” attribution. By doing so, hijackers unfairly benefit from sales or actions they did not genuinely influence, undermining affiliate programs and eroding trust. Affiliate Hijacking is a subset of broader affiliate fraud and often results in skewed performance data and financial loss for both affiliates and merchants.
