South Korea Imposes $400M Fine on Coupang for Major Data Breach Affecting Millions
South Korean authorities have levied a record-breaking fine of over $400 million on Coupang, a retail giant headquartered in the U.S., following a data breach that compromised the personal information of more than 34 million customers. The breach, discovered in December 2025, involved a former employee accessing names, email addresses, phone numbers, and order histories. The Personal Information Protection Commission in Seoul issued the maximum penalty, marking a significant enforcement action against a U.S.-based company. Coupang has announced plans to challenge the decision, while the case has sparked political tensions, with some U.S. lawmakers reportedly linking the breach to bilateral relations between the U.S. and South Korea.
