President Lee Jae Myung on Sunday ordered a thorough investigation into a string of recent data breaches at local banks, as artificial intelligence (AI)-powered cyberattacks increasingly target financial firms. According to Cheong Wa Dae, Lee was briefed on recent data breaches at financial and public institutions and their responses to the incidents. "The president ordered officials to conduct a thorough investigation and make every effort to devise measures, with a grave awareness of the seriousness of the matter," presidential spokesperson Kang Yu-jung said. The remarks came after a series of data breaches at major financial firms over the past several days. Shinhan Bank on Thursday reported a breach affecting about 25,000 customers, followed by incidents at KB Kookmin Bank, Hana Bank and BNK Busan Bank on Friday. The leaked information included customers' names and phone numbers, as well as annual income and loan limits. Some customers' resident registration numbers were also exposed. The breaches have since spread beyond major banks to nonbank financial institutions. Yegaram Savings B
