CISA Urges Organizations to Secure Microsoft Intune Environments Following Stryker Breach

CISA issued an urgent alert after a March 11, 2026 cyberattack on Stryker Corporation that leveraged Microsoft Intune endpoint management to obtain privileged access across enterprise devices; the alert warns that misuse of legitimate endpoint management platforms can enable application deployment, configuration changes, endpoint wiping, and large-scale lateral movement. CISA recommends applying Microsoft’s Intune hardening best practices—least-privilege RBAC, phishing-resistant MFA, Privileged Identity Management, Conditional Access, and Multi Admin Approval for sensitive operations—to reduce blast radius and prevent single-account compromises from causing widespread damage.
