KR: Coupang files lawsuits against 620 billion won fine over data leak

Coupang, South Korea's largest online retailer, is filing lawsuits against a 620 billion won fine stemming from a November 2025 data breach that exposed personal information of over 33 million customers. The incident and its regulatory aftermath have remained a prominent issue for nine months following the company's initial disclosure in December 2025.

Why it matters: South Korean retailers and their customers should monitor this case for precedent on breach liability and penalties; practitioners in regulated markets need to understand how delayed incident response and disclosure decisions compound regulatory exposure.
