In this episode of Fraudology Karisse Hendrick provides important updates on Visa's Acquirer Monitoring Program (VAMP) and explores how recent tariffs are impacting e-commerce fraud. Hendrick explains that VAMP implementation has been delayed until October 1st, with fines not taking effect until January 2024. She clarifies that acquirers will likely pass VAMP fees onto merchants exceeding certain fraud ratios. Notably, Visa is expected to announce that alerts from Ethoca, CDRN, and RDR will now count towards reducing merchants' fraud ratios - a significant change from previous announcements. Hendrick also discusses how post-authorization systems may be negatively impacted by VAMP and Visa's new enumeration program.

The episode then delves into the fascinating ripple effects of recent tariffs on e-commerce fraud patterns. Karisse shares insights from conversations with retail executives, revealing how tariffs are leading to customs delays, increased chargebacks, electronic stockpiling that triggers fraud systems, and the creation of "straw merchants" to avoid fees. She explains how fraudsters are exploiting Canadian accounts for cross-border schemes and how freight forwarding services are surging. Throughout, Hendrick emphasizes how these trends are straining fraud departments and forcing them to re-evaluate what constitutes suspicious behavior.

The bug that makes you passionate about identifying & preventing cybercriminals from getting away with stealing from your company, or your client's companies.
