A 26-year-old Chinese resident from Guangdong Province is suspected of using artificial intelligence tools to hack into South Korea's banking system. According to a report by the American cybersecurity company CrowdStrike, the suspect used the Chinese agent tool ARTEX and Anthropic's Claude Code. The activity, which began in late September, affected at least nine banks across South Korea. Two major banks, Shinhan Bank and Kookmin Bank, reported personal information leaks of approximately 25,000 and 119 customers, respectively. CrowdStrike noted that the activity is not attributed to geopolitical tensions but to individual economic motives. The suspect also asked Claude for help in finding data-selling groups on Telegram and requested the creation of a security researcher's resume. South Korean police have launched an investigation, and President Lee Jae-myung called for firm measures. Anthropic, South Korean police, and China's foreign ministry have not yet publicly commented on the case.
