- •The fine is the largest ever for a single data breach in South Korea.
- •Coupang's request to suspend the fine was denied, but enforcement of corrective orders was temporarily paused.
A Seoul court upheld a 423.6 billion won ($315.6 million) fine against Coupang for a significant data breach affecting 37.5 million users. The breach, reported in November 2025, involved unauthorized access to personal information, including names and phone numbers. The court rejected Coupang's request to suspend the fine but temporarily halted enforcement of corrective measures mandated by the Personal Information Protection Commission (PIPC). The corrective orders require Coupang to enhance security measures and notify affected individuals. This fine is the largest ever imposed in South Korea for a single data breach. The court's decision is part of an ongoing legal battle, with a main lawsuit from Coupang seeking to overturn the sanctions yet to be scheduled for a hearing.
