ARTEX AI and Claude Agents Weaponised in Korean Bank Attacks
A Chinese-speaking threat actor deployed the ARTEX AI agentic penetration testing suite alongside Claude Code agents and multiple LLM backends to attack major South Korean banks, exfiltrating customer data and causing system outages. The attack represents a documented real-world case of AI agents being used end-to-end in a financially motivated intrusion campaign. Exposed session histories and configuration files left in open directories enabled CrowdStrike to attribute the attack with high confidence and surface the attacker's probable identity.
