The security firm Ierae found that the server used for the Japanese campaign concentrated its attacks on a single industry, affecting nine of the targeted firms. CrowdStrike tied the operation to a likely Chinese-speaking, financially motivated actor who repurposed the ARTEX tool, originally built for authorized network defense, to conduct cross-border attacks." --- # Single Person's AI Stack Breached 20 Japanese Firms and 7 Korean Banks > [Open the canonical story]() **Published:** 2026-10-22T00:09:44.000Z **Category:** Agents **Topics:** deepseek, agent ## Summary A single attacker used a toolchain of AI agents including ARTEX, DeepSeek v4\.1\-Flash, GLM\-5\.3, Grok 4\.6, and Claude Code to breach approximately 20 Japanese companies and seven South Korean banks, according to a report from CrowdStrike\.
