Enumeration at Scale: How Fraudsters Are Testing the Payments Ecosystem | Presented by Visa
Summary
Payment fraud has evolved from stolen databases to real-time, automated attacks. Enumeration – the systematic testing of payment credentials at scale – is now reshaping the card-not-present fraud landscape and challenging traditional approaches to fraud prevention.
This session will unpack why enumeration is growing, how attackers exploit payment flows, and why fraud can materialize quickly after successfully guessing card credentials. The goal is to provide attendees with a practical view of how speed, scale, and automation are changing the economics of payment fraud and what this means for them, while exploring emerging areas of enumeration risk and the role of layered controls, real-time analytics, and ecosystem collaboration in reducing fraud exposure.
Our aim is to provide a clearer view of the threat, the stakes, and the opportunity for the payments industry to stay ahead of enumeration and help protect the future of digital commerce.
What You'll Learn
- Define enumeration and explain how systematic payment credential guessing differs from traditional payment data compromise.
- Understand how speed, scale, and automation are changing payment fraud, including why enumeration can lead to fraud shortly after credentials are successfully guessed or validated.
- Identify key strategies to reduce enumeration risk, including layered controls, real-time analytics, and ecosystem collaboration.
