Korea Electric Power Corp. said personal information belonging to about 24,000 employees was exposed on an external website, in the latest data-leak incident reported in South Korea. KEPCO said it became aware of the exposure at about 3:59 p.m. Thursday and completed deleting the information around midnight Friday. The exposed data included employees' names, job positions and telephone numbers, but not sensitive details such as resident registration numbers. Customer information, held in a separate system, was not compromised. KEPCO has notified affected employees and is verifying the exact cause. The company said the incident appears unrelated to artificial intelligence-related hacking attacks recently affecting Hana Bank, KB Kookmin Bank and Shinhan Bank.
