Visa Account Attack Intelligence (VAAI) Score
The Visa Account Attack Intelligence (VAII) Score is a fraud-detection tool developed by Visa to help institutions assess the likelihood that a specific payment card or account has been targeted or compromised in a cyberattack. Using machine learning and advanced analytics, the VAII score evaluates transaction patterns, account behaviors, and other risk factors to assign a numerical score indicating the probability of an account being involved in fraudulent activity. This score helps organizations prioritize high-risk accounts for further investigation or action.
Leveraging the VAII Score can enhance fraud prevention strategies and inform real-time decision making to improve the efficiency of fraud-detection efforts. Combining VAII with even more advanced fraud detection tools helps create a comprehensive approach to identifying and mitigating account-based fraud.
