South Korea fines Coupang record $400M+ for data breach affecting 34 million customers
Summary
South Korean regulators fined Coupang a record 624 billion won ($400M+) for a 2025 data breach that exposed personal data of over 34 million customers — roughly two-thirds of South Korea's population. A former employee accessed names, emails, addresses, phone numbers, and order histories over several months. Coupang, a U.S.-headquartered e-commerce giant popular in South Korea, plans to challenge the fine. The case is notable as U.S.-based companies rarely face such severe penalties for data breaches due to limited enforcement powers.
