Carding service Jerry’s Store leak exposes 345,000 stolen payment cards

Jerry’s Store, a card-checking service used by fraudsters, exposed roughly 345,000 stolen payment cards after an AI-assisted build (Cursor) created an unauthenticated web directory; about 145,000 records were valid, containing full cardholder data (numbers, CVVs, expiries, names, addresses), potentially enabling large-scale fraud and resale on criminal markets.
