China-Linked Hackers Use ARTEX AI Against Microsoft 365 Tenants

Original: China-Linked Hackers Use ARTEX AI to Target 2,250 Microsoft 365 Tenants After ConnectWise Breach Details: https:// cyber

Hackers aligned with China have used ARTEX, an AI-powered penetration-testing framework, to attempt access to some 2,250 Microsoft 365 tenants, according to a cybersecurity report circulating widely online. The campaign reportedly follows the disclosure of details from a ConnectWise breach, suggesting attackers leveraged that intelligence to scale automated, AI-assisted intrusions against cloud email environments. Security observers are treating it as an early example of AI tooling being repurposed for offensive operations at scale.

Why now: The combination of state-linked hackers, a newly disclosed ConnectWise breach, and offensive use of AI tooling has made the story a talking point in cybersecurity circles.
