Executive Summary
In January 2023, Eye4Fraud, an e-commerce fraud-prevention/order-verification service, suffered a data breach; the data was listed for sale on a hacking forum in February 2023 and added to Have I Been Pwned. It contained ~16 million unique email addresses across ~147 tables (~65GB), including names and bcrypt password hashes for users, and names, phone numbers, physical addresses, and partial credit-card data (card type and last four digits) for orders. Full card numbers were not exposed. Affected individuals are largely merchants' end customers who never directly used Eye4Fraud. (NOTE: display count corrected from 525K to ~16M per HIBP; prior "full credit card" corrected to partial.)
ObscureIQ assessment: High risk because the platform concentrates fraud, transaction, and merchant data in one place. Exposure enables merchant impersonation, transaction abuse, and reverse-engineering of fraud controls.
Breach Impact
The breach exposed identity, contact, and order data, including bcrypt-hashed passwords and partial credit-card details (card type + last four), for merchants' end customers who never directly interacted with Eye4Fraud. This enables targeted phishing, order/payment-themed scams, and credential-stuffing (password hashes), though full card numbers were not exposed. There is notable irony in a fraud-prevention vendor leaking customer data.
