South Korea Scrambles to Learn Whether AI Supercharged Bank Hacks
South Korea has opened an urgent inquiry into whether artificial-intelligence agents helped drive recent cyberattacks on the country’s banks, after President Lee Jae Myung said the government had detected troubling signs.

The concern surfaced publicly on Tuesday, when Lee told a cabinet meeting that “signs have emerged” that AI models were used in some of the attacks. He said the prospect was “causing considerable public concern and anxiety,” shifting the issue from a routine cybersecurity investigation into a broader test of whether increasingly capable AI tools are expanding the risks to critical financial infrastructure.

Lee’s immediate response was to order officials to establish what happened “swiftly and clearly.” He also directed ministries to deploy the personnel and resources needed to limit any damage, signalling that the government sees the suspected use of AI not simply as a technical detail but as a potential escalation in the threat facing banks.

For now, however, the official account remains notably thin. Authorities have not identified who was behind the hackings, explained how any AI models may have been used, or described the scale of the intrusions and their impact on customers or institutions.

That gap defines the story’s central tension: Seoul is warning of a potentially consequential new cyber risk while still working to verify the evidence. The investigation will determine whether the AI element marks a genuine shift in the mechanics of bank attacks—or an early alarm whose full meaning remains unclear.
