In a post on October 21, Microsoft says Storm-0940, a group it assesses as China-state aligned, has used ARTEX since as early as September 2026. ARTEX is an open-source penetration testing framework built on AI agents that can use any AI model. The group targeted hundreds of organizations; most of the targeting failed, but in multiple instances it reached privileged cloud access in under 3 hours. Microsoft says no vulnerability in its own products was involved. Why it matters: according to Microsoft, agents can work around the clock and try several breach paths at once.
