Microsoft Links ConnectWise Attack to Chinese State-Aligned Group Using ARTEX AI High·4 outlets·Microsoft via The RecordNewRead A Chinese group used ARTEX AI to conduct a high-speed supply chain attack against ConnectWise.
Microsoft attributed a recent supply chain attack on ConnectWise to a Chinese government-aligned group named Storm-0940. This actor utilized an AI penetration testing framework called ARTEX to automate and accelerate attacks against cloud infrastructure. The group was observed making high-volume sign-in attempts against ConnectWise services.

Why it matters. The use of agentic AI allows threat actors to significantly increase the speed and scale of complex attacks, reducing the time from targeting to achieving privileged access. This pace exceeds human detection and response capabilities.

Do this today Monitor for high-volume, sustained authentication attempts against cloud services.

Affected
