South Korean president affected by data breach

South Korean President Lee Jae Myung has fallen victim to a data breach that exposed his sensitive personal information online for months, according to an investigation conducted by the South Korean public broadcaster KBS. The breach reportedly included President Lee's passport numbers, dates of birth, and passport validity details. Notably, the breach impacted not only the president but also his wife, security advisers, office staff, bodyguards, his personal physician, and several journalists.

The sensitive data was published on a paid security platform under the title "Passenger List (Republic of Korea-Belgium)" in an Excel file. This file, believed to contain the passenger list for President Lee's presidential aircraft during his June European trip, had been uploaded a week prior to the trip and remained available for download by paying users.

In response to the breach, the President's Office announced an investigation into the incident and initiated immediate countermeasures. South Korea is widely recognized as a technologically advanced and highly connected nation.
