Coupang fined KRW 624.7B, Korea's largest privacy sanction

Under appeal

The PIPC found that a 2025 breach at Coupang, carried out by a former employee using authentication signing keys the company had not revoked, stemmed from basic security failures rather than sophisticated hacking, and that Coupang notified it late. Separately, it found that Coupang collected the online behaviour of about 11.17 million users on other websites and apps without consent.
