- South Korea fined Coupang 625 billion won for a major customer data leak and unauthorized data collection.
- Over 33 million customers’ personal information was exposed, and the breach was not detected within the required 72 hours.
- The penalty represents 1.4% of Coupang’s estimated 2025 revenue of 45 trillion won.
- The investigation identified insufficient security measures and illegal collection of online data from approximately 11 million customers without consent.
This accident occurred due to Coupang's lack of safety measures and systems, not sophisticated hacking.— Song Kyung-hee, chairperson of the Personal Information Protection Commission, told a briefing on Thursday.
