What Is Chargeback Fraud Using Counterfeit Evidence? Quick Answer + Definitions

Chargeback fraud with counterfeit evidence--often called "friendly" or first-party fraud--occurs when a customer receives goods/services but submits forged documents (e.g., photoshopped receipts, fake tracking, altered invoices) to their bank or processor to reverse a legitimate transaction. This exploits cardholder protections, leaving merchants out of pocket.

Core Definition: Per FTC guidelines, legitimate disputes cover billing errors or non-delivery, but fakes violate fraud laws by deceiving issuers with tampered proofs. Common tactics include editing PDFs in Photoshop for "non-receipt" claims or fabricating shipping labels for PayPal disputes.

High-Level Risks: Global invoice fraud costs $3B annually (Undetectable.ai 2025); 36% of attacks are first-party fraud (LexisNexis via AI Fraud Detection 2026). FTC advises keeping receipts for fixes, but fraudsters fake them.

Quick Prevention: Verify docs via metadata, vendor calls, and AI--win rates soar 300% with tools (Mastercard 2025).
