Coupang has submitted thousands of documents and videos, including communications with Korean authorities and footage from a December 2025 parliamentary hearing, to the US House Judiciary Committee ahead of a subpoena for Harold Rogers. The investigation focuses on alleged discrimination against US tech giants by the Korean government, with subsequent reports and hearings expected.

The fallout from Coupang’s massive data breach continues to escalate, intertwining legal, political, and diplomatic challenges across South Korea and the United States.

⚖️ Data Breach Scope, Regulatory Action, and Corporate Response

Authorities confirmed on February 10, 2026, that Coupang’s breach exposed names, phone numbers, email addresses, delivery details, and lobby codes, impacting nearly all Coupang users in South Korea. Coupang’s delayed reporting and failure to preserve evidence triggered fines and a formal investigation by the science ministry. The company later admitted an additional leak of over 165,000 accounts not initially disclosed, but disputes official findings, asserting only 2,609 accounts with lobby codes were leaked. Meanwhile, South Korea’s privacy authority fined Louis Vuitton Korea (21.4 billion won), Dior Korea (12.2 billion won), and Tiffany Korea (2.4 billion won) for similar breaches. The next step in the police investigation is to secure the suspect behind the Coupang leak, with authorities actively pursuing leads.
