Multiple South Korean financial institutions were breached; reports say attackers may have used AI automation tools

According to the Kyunghyang Shinmun, South Korea's financial regulator held an emergency inspection meeting on October 4 in response to external intrusions and personal information leaks at multiple financial institutions. The report says Shinhan Bank leaked 25,727 pieces of personal information, while Kookmin Bank and Hana Bank involved 119 and 89 customers respectively; these figures come from that report, and other media may use different statistical methods. The attacks mainly involved peripheral systems such as loan inquiries and employee workstations. Some experts and the report speculate that attackers used AI automation tools, but such attribution still requires further verification. The incidents are network intrusions carried out by attackers using tools, and it is not yet sufficient to conclude that autonomous AI or a specific open-source model caused these losses.
