A 26-year-old suspect based in China's Guangdong province allegedly targeted South Korean financial institutions between late September and early October using AI tools.
CrowdStrike reported that the attacker used the Chinese open-source tool ARTEX alongside Anthropic's ClaudeCode to conduct penetration testing and research data sales.
The breaches affected at least nine South Korean banks, prompting a police investigation and calls for a robust response from President Lee Jae Myung.
