Chinese-speaking hackers used AI pentest suite against South Korean banks

Original: 🤖 Chinese-speaking actor used the ARTEX AI pentest suite + Claude agents (DeepSeek v4.1-flash, GLM-5.3, Grok 4.6 backend

A Chinese-speaking threat actor used the ARTEX AI penetration testing suite, running Claude agents with DeepSeek, GLM and Grok backends, to attack Shinhan, KB Kookmin and Hana Bank in South Korea. Client data and card information were exposed, and CrowdStrike traced open directories leaking Claude Code session logs.

Why now: The use of commercial AI agents to automate attacks on major banks marks an escalation in AI-driven cybercrime.
