What happened

A China‑aligned nation‑state group (Storm‑0940) used the Artex LLM‑driven framework to conduct automated reconnaissance, password‑spraying, and OAuth‑application abuse against ConnectWise’s cloud‑backup platform, generating >2,250 tenant sign‑in attempts at ~3,000 per minute. ConnectWise detected the activity, suspended services, and began an investigation; no successful breach has been confirmed.

Why it matters for trust and compliance

  • The campaign illustrates why continuous monitoring of third‑party access and automated credential‑spray detection are core control objectives for a trustworthy supply‑chain posture, providing defensible evidence for audit readiness.
  • Map third‑party risk controls to continuous monitoring objectives and collect real‑time evidence.
  • Validate OAuth‑grant governance and enforce MFA to reduce credential‑spray exposure.
