On November 2, 2026, the personal information of South Korean President Lee Jae-myung and his spouse was leaked on the internet for five months. The list, titled "Passenger List (South Korea-Belgium)," included high-ranking officials such as Kim Yong-bum, Director of the National Security Office at the Blue House, and Han Sung-sook, Minister of Small and Medium Enterprises, affecting a total of 168 people. The leak is believed to have originated from a security-related paid website that scans for malicious code, operated by a subsidiary of a well-known tech giant, which allows users to upload files without restrictions. The leaked information included full names, affiliations, dates of birth, passport numbers, and dates of issuance and expiration, posing the risk of impersonation or targeted attacks if combined with other personal data. Authorities are currently investigating the source of the leak, considering both government agencies and security-related websites as potential culprits.
