KEPCO says employee data leaked, customer records safe

Korea Electric Power Corp. said personal information for about 24,000 employees was exposed on an external website, The Korea Times reported. The company said customer information was kept in a separate system and was not compromised.

The exposure adds to data-security concerns in South Korea after recent customer data leaks at major financial firms, according to The Korea Times. KEPCO said the incident appears unrelated to AI-related hacking attacks at financial firms.

The leaked information included employee names, job positions and telephone numbers, according to The Korea Times. KEPCO said the data did not include sensitive information such as resident registration numbers.

KEPCO said in a statement, "We became aware that the personal information of employees was exposed on an external web site at around 3:59 p.m. Thursday," according to The Korea Times.

The company said it notified affected employees after discovering the exposure. KEPCO said it completed deleting the leaked information at around midnight Friday, The Korea Times reported.

Customer information was not affected because it was stored in a separate system, according to KEPCO as reported by The Korea Times.

The Korea Times reported that the case followed recent customer data leaks involving Hana Bank, KB Kookmin Bank and Shinhan Bank. KEPCO said the exact cause of the incident remained under verification.

KEPCO said it is verifying the cause of the exposure while maintaining that customer records were not involved.
