South Korean President Lee Jae Myung has ordered a thorough investigation into a widening wave of cyberattacks on the country’s financial industry. The presidential office said on Sunday that the probe would cover recent personal data leaks at banks, finance companies and public agencies. Financial Services Commission chairman Lee Eog-weon convened an emergency meeting with regulators and bank executives on Sunday afternoon. The session had been planned for October 7 but was brought forward as new breaches emerged. The attacks first surfaced at major banks. Shinhan Bank said data of about 25,000 customers was exposed, while KB Kookmin Bank and Hana Bank reported breaches affecting 119 and 89 customers. BNK Busan Bank said data of 11 outsourced developers was exposed. Yegaram Savings Bank said about 40,000 customers may be affected, and Hyundai Capital reported an attack on a site holding data of 146 loan recruiters. Woori Bank and NH NongHyup were also targeted, with no confirmed leaks so far. The FSC chairman said AI may have been used in the attacks, calling for an ‘AI attacks defended by AI’ approach. Regulators believe attackers scanned many firms for weaknesses.
