South Korea Drops a $409M Fine on Coupang in Historic Data Breach Ruling

South Korea’s Personal Information Protection Commission fined Coupang a record 624.7 billion won (~$409M) after a breach—believed to have occurred from June 2025—where a former developer retained an authentication key and accessed customer data for about a year; regulators say roughly 37.5 million accounts were affected (names, phone numbers, addresses, order histories and some building entry codes), Coupang disputes the scale, offered large customer compensation, its CEO resigned, and the company faces major financial and reputational damage.
