**Coupang CEO Resigns Following Major Data Breach in South Korea**
On December 10, 2025, South Korea’s largest online retailer, Coupang, announced the resignation of its CEO, Park Dae-jun, who stepped down to take responsibility for a significant data breach affecting the company. The incident prompted leadership changes, with Harold Rogers, chief administrative officer of Coupang’s U.S. parent company, appointed as interim CEO.
The breach’s scope and impact remain under investigation, but the resignation underscores the severity of the incident. Coupang, a dominant player in South Korea’s e-commerce market, has not yet disclosed further details about the breach’s timeline or affected data. The move reflects growing corporate accountability in the wake of cybersecurity failures, particularly in high-profile digital platforms.
