A data breach at Coupang, affecting over 30 million users, has been attributed to management failures rather than a sophisticated cyberattack. Investigators found that a former employee exploited vulnerabilities in the authentication system, gaining unauthorized access from April 2025 until November 2025. Coupang disputes the findings, claiming only a limited number of accounts were affected.
