South Korean President Lee Jae Myung says there are signs AI models may have been used in recent cyberattacks against several major banks. "In some hacking incidents, signs have emerged of AI being used, causing considerable public concern and anxiety," Lee said during a cabinet meeting. "Please establish the circumstances swiftly and clearly, and concentrate personnel and resources on minimizing the damage." Reuters reports: South Korea's police have launched a full-scale investigation into the hacking attacks against commercial banks that led to a breach of customers' personal information, the Yonhap news agency reported on Tuesday. Shinhan Bank, KB Kookmin Bank and others had reported cyberattacks, the Financial Services Commission (FSC) said on Friday, while Yonhap reported that Hana Bank and Woori Bank also suffered breaches. Authorities have not yet disclosed details on what kind of AI tools were used in the hacking incidents or the full scale of the breaches.

On Sunday, FSC Chairman Lee Eog-weon convened an emergency meeting with financial industry associations, regulators and executives from affected institutions, warning that the sector must respond with the highest level of vigilance. Financial watchdog the Financial Supervisory Service (FSS) and the Financial Security Institute shared data about 28 unique IP addresses and some country information linked to the recent hacking attempts with the financial sector, the FSS said on Tuesday.
