Presidential Probe: Seoul Confirms AI Deployment in Commercial Bank Cyberattacks

Offensive artificial intelligence has crossed into the domain of threats to national stability. On October 6, 2026, South Korean President Lee Jae-myung officially confirmed that a recent, unprecedented wave of breaches targeting domestic financial institutions exhibits clear hallmarks of autonomous AI deployment.

Customer database leaks across multiple commercial banks prompted regulators to urgently distribute a blacklist of 28 malicious IP addresses associated with the attackers. State police have launched a top-tier national security probe. This marks an alarming wake-up call for global central banks: threat actors have learned to automate vulnerability reconnaissance and bypass intrusion defenses at machine speed. If AI-driven cyber operations can simultaneously compromise the banking apparatus of an advanced tech economy, the financial sector faces an immediate overhaul of its defense doctrines, severance of external gateways, and forced isolation of transaction backbones.
