South Korea's foreign ministry said Tuesday it is reissuing passports for 168 people, including President Lee Jae Myung and first lady Kim Hea-kyung, after personal data tied to the president's June Europe trip appeared on a paid website^1,2.

KBS reported Monday that a file labeled as a passenger list, posted in early June, included passport information for Lee, security officers and National Security Adviser Wi Sung-lac¹.

The ministry said the group also included cabinet members, presidential-office and foreign-ministry officials, security staff and reporters traveling with the delegation².

Exposed fields reportedly included Korean and English names, affiliations, job titles, dates of birth, passport numbers and issuance and expiration dates².

The file was said to have been available on a paid security-related site since June 2, before Lee left for Belgium, Italy and a Group of Seven meeting in France, and to have remained accessible for months^1,2.

KBS said it notified the presidential office after learning of the posting; the office said it was looking into the matter¹.

Foreign ministry spokesman Park Doo-soon said the ministry was moving quickly on reissuance for all those affected².

Police opened a preliminary investigation after passenger information related to the presidential aircraft was found online, and the ministry said it had asked for an inquiry, ordered the material taken down and was inspecting computers and email accounts used for the June trip².

Investigators have not publicly identified who posted the file or whether it was an inside leak or an outside actor^1,2.

Lee separately told a cabinet meeting Tuesday that inspection-centered security systems were showing limits and asked officials to consider a governmentwide cybersecurity coordinating body².
