In response to a surge in sophisticated fraud mechanisms, Visa has announced an innovative solution aimed at countering enumeration attacks, a prevalent threat in the digital payment landscape. The new Visa Account Attack Intelligence (VAAI) Score utilizes generative AI to assess and score the risk of these attacks in real-time, providing issuers with a vital tool to mitigate potential losses.
"Enumeration can have lasting impacts on our clients and there’s an immediate need for tools that can better detect and prevent these attacks in real-time," said Paul Fabara, Chief Risk and Client Services Officer at Visa. This tool aims to significantly decrease fraud-related losses, which currently amount to an alarming $1.1 billion annually, highlighting the urgent need for such preventive measures.
"Enumeration can have lasting impacts on our clients and there’s an immediate need for tools that can better detect and prevent these attacks in real-time,"
The VAAI Score is designed to assess the likelihood of enumeration attacks specifically within card-not-present (CNP) transactions, which are increasingly targeted by cybercriminals using automated scripts and botnets. According to Visa, approximately 33% of accounts that have undergone enumeration experience fraudulent activity within five days of the initial compromise, prompting further concern among financial institutions.
Understanding the rapid evolution of fraud tactics is crucial. "With access to advanced technology, fraudsters are monetizing stolen credentials faster than ever before," noted Michael Jabbara, Senior Vice President and Global Head of Fraud Services at Visa. The VAAI Score employs generative AI capabilities to differentiate between normal and abnormal transaction patterns, allowing it to predict potential enumeration threats effectively.

By integrating this tool into their systems, issuers can implement a more informed decision-making process regarding transaction approvals. The VAAI Score provides risk assessments in just 20 milliseconds, enabling issuers to make swift and timely decisions during transaction authorizations.
Impact and Legacy
"Enumerated transactions impact the entire ecosystem, and with the VAAI Score, we’re giving our clients a sophisticated tool that can help prevent cardholder accounts from being compromised and stop fraudulent transactions before they happen," emphasized Jabbara. This proactive approach is expected to enhance overall transaction security while minimizing inconvenience for legitimate cardholders.

The tool doesn't just focus on reducing fraud; it also emphasizes improving the customer experience. By identifying legitimate transactions that do not pose a threat, issuers can avoid unnecessary disruptions for cardholders. The VAAI Score is anticipated to reduce false positives by an impressive 85% compared to existing risk models, ensuring a more streamlined transaction process.
This innovative scoring model has been trained on over 15 billion transactions from VisaNet, integrating six times more features than its predecessors to more accurately assess suspicious activities. By analyzing each CNP transaction against established enumeration patterns, the VAAI Score generates a precise risk score, which is crucial for determining approval or denial of transactions.
Through ongoing investment in technology and security, Visa continues to prioritize safety in digital payments. Over the past five years, the company has allocated more than $10 billion towards enhancing its security infrastructure, a testament to its commitment to protecting clients and their assets.
Looking Ahead
In summary, Visa’s introduction of the VAAI Score represents a significant advancement in the fight against enumeration attacks. As fraudsters grow more sophisticated, Visa’s ability to leverage generative AI can empower issuers to safeguard their operations while delivering a smoother experience for customers. The active engagement of stakeholders in adopting such tools is essential to combatting the growing threat in the digital payment environment. Overall, the launch signifies a proactive stance in not only addressing current challenges but also adapting to future fraud trends.
