South Korea’s Personal Information Protection Commission has imposed a $408 million fine on e-commerce leader Coupang following a significant data breach. The breach, considered the largest in the nation’s history, compromised the personal information of over 72 million customers. Investigators found Coupang failed to adequately protect user data and delayed reporting the incident, violating data protection laws. The commission cited insufficient safety measures as a key factor contributing to the vulnerability. The fine represents a substantial penalty, signaling a stricter approach to data security enforcement in South Korea. Coupang has pledged to improve its data protection systems and cooperate with authorities. The incident raises concerns about the security of personal data held by major online platforms.
