CISA Calls on Organizations to Strengthen Microsoft Intune Security After Stryker Incident
The Cybersecurity and Infrastructure Security Agency (CISA) has issued a critical alert urging organizations to enhance the security of their endpoint management systems.
The Cybersecurity and Infrastructure Security Agency (CISA) has issued a critical alert urging organizations to enhance the security of their endpoint management systems.
On March 18, 2026, CISA released this alert following a significant cyberattack on Stryker Corporation, a medical technology provider based in the U.S. The agency identified malicious actors targeting endpoint management platforms and exploiting legitimate administrative software to infiltrate corporate networks.
The attack on Stryker, which took place on March 11, 2026, severely affected the company's Microsoft infrastructure. In response, CISA is coordinating with the Federal Bureau of Investigation (FBI) and other federal partners to monitor threats and implement mitigation strategies. Microsoft and Stryker are providing vital intelligence to assist the cybersecurity community in counteracting similar threats.
Administrators are advised to implement the principle of least privilege to prevent the abuse of legitimate endpoint management software. CISA recommends using Microsoft Intune’s role-based access control (RBAC) architecture. This ensures administrative roles are granted only the necessary permissions for daily operations.
Organizations should define the actions allowed for specific roles and the users and devices those actions can affect. Securing privileged access is essential to prevent lateral movement by threat actors. CISA advises enforcing phishing-resistant multi-factor authentication (MFA) on all administrative accounts.

By utilizing Microsoft Entra ID features such as Conditional Access policies, risk signal monitoring, and privileged access controls, organizations can block unauthorized administrative actions within the Microsoft Intune environment.
A key vulnerability in endpoint management platforms is the execution of high-impact commands by compromised accounts. To mitigate this risk, security teams should configure access policies requiring Multi Admin Approval in Microsoft Intune. This safeguard requires a second authorized administrator to approve changes to sensitive configurations, including remote device wiping, application deployment, script execution, and RBAC modifications.
CISA and Microsoft recommend reviewing technical frameworks to enhance network defenses against endpoint management exploits. Security teams should consult Microsoft's guidance on securing Intune, focusing on Multi Admin Approval policies and zero trust security principles.
Organizations should implement robust role-based access control and plan for Privileged Identity Management (PIM) deployments across Microsoft Entra ID. For authentication strategies, CISA’s guidelines on deploying phishing-resistant multifactor authentication protocols are recommended.
Applying these security principles to Microsoft Intune and other endpoint management software can significantly reduce the risk of compromise. Network administrators are encouraged to audit their infrastructure configurations to prevent potential exploitation.
