AI-Driven Cyberattack Targets South Korean Banks, Stealing Over 25,000 Records

A suspected Chinese-speaking hacker employed AI-powered tools to breach multiple South Korean banks, resulting in the theft of more than 25,000 customer records from Shinhan Bank, according to The Decoder.

The attacker used ARTEX, an open-source platform that integrates AI models such as DeepSeek and GLM-5.3 to automate penetration testing. CrowdStrike highlighted that this incident underscores how AI technology enables a single individual to execute large-scale cyber breaches.

For Japanese markets, this event signals growing cybersecurity risks in the financial sector, emphasizing the need for enhanced AI-driven defense measures amid increasing digital threats across Asia.
