What Happens if a Merchant Experiences a Fraud Attack?

If your business experiences a fraud attack (for example, card testing, stolen card use, or a sudden spike in suspicious transactions), the acquiring bank and processor may review recent activity to assess risk and exposure. Reviews often focus on transaction patterns, verification results (such as AVS and CVV), shifts in volume or ticket size, fulfillment or delivery status, and whether processing behavior remains aligned with what was approved during Underwriting. Fraud events can also increase future dispute risk if impacted transactions later become Chargebacks.

Depending on severity, temporary controls or account adjustments may be introduced while activity is evaluated, such as tighter risk settings, additional verification requirements, transaction monitoring, or limits on certain activity. The exact response and timing are determined by the acquiring bank and processor based on the situation.

Easy Pay Direct helps you set up preventative tools to reduce fraud risk before an attack occurs, and if an incident happens, we can assist with steps to limit the damage. This can include helping you review the fraud pattern, tightening fraud rules and velocity limits, blocking high-risk traffic signals (such as specific IP ranges or geographies), adjusting verification settings, and documenting what occurred so you can communicate clearly with banking partners. We also help you understand what information may be requested during reviews and how to stabilize processing going forward within approved parameters.
