Park Dae-jun has resigned as CEO of Coupang following a severe data breach, which compromised the personal information of over 34 million South Koreans, amounting to more than half the nation's population. Park stated he feels a "deep sense of responsibility" regarding the incident. Coupang has appointed Harold Rogers, the legal head of its U.S. parent company, as his successor. This breach adds to a troubling trend of cyber incidents affecting major firms in South Korea.
