CrowdStrike reports that a suspected Chinese-speaking attacker used the open-source AI penetration tool ARTEX to breach multiple South Korean financial institutions between late September and early October 2026, stealing over 25,000 sensitive records from Shinhan Bank alone. The incident highlights how LLM-driven automated attack tools (powered by models like DeepSeek v4.1-flash and GLM-5.3) significantly lower the barrier for cybercrime, enabling a single individual to execute massive data breaches in a short timeframe.
