The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued an urgent advisory calling on organizations to strengthen endpoint management system configurations following a cyberattack on Stryker Corporation, a U.S.-based medical technology company, on March 11, 2026. The incident, which targeted Stryker’s Microsoft environment, has prompted CISA to collaborate with the Federal Bureau of Investigation (FBI) to assess potential broader risks and identify additional threats.
According to the agency, the attack highlights a growing trend in which threat actors focus on endpoint management platforms particularly Microsoft Intune to gain privileged access across enterprise networks. By exploiting these systems, attackers can execute a wide range of actions, including deploying malicious applications, modifying device configurations, wiping endpoints, and moving laterally across infrastructure at scale. CISA noted that the attack did not rely on traditional malware alone but instead leveraged legitimate administrative tools. This “living-off-the-land” approach allows attackers to blend in with normal operations, making detection significantly more difficult and emphasizing the need for stricter controls within trusted platforms.
In response, CISA is urging organizations to adopt Microsoft’s latest security best practices for Intune and similar endpoint management solutions. A key recommendation is enforcing the principle of least privilege through role-based access control (RBAC). By limiting administrative permissions to only what is necessary, organizations can reduce the potential impact of compromised accounts.
The agency also stressed the importance of implementing phishing-resistant multi-factor authentication (MFA), particularly for privileged users. Leveraging identity security features such as Conditional Access policies, risk-based authentication, and privileged access controls can help prevent unauthorized access and reduce the likelihood of credential-based attacks Another critical safeguard highlighted by CISA is the use of Multi Admin Approval (MAA). This feature requires a second administrator to authorize high-risk actions, such as device wipes, application deployments, or configuration changes. By adding this layer of verification, organizations can prevent a single compromised account from causing widespread disruption.
CISA further recommends adopting Zero Trust principles across endpoint management environments. This includes continuous identity verification, strict access policies, and real-time monitoring of administrative activities. The use of Privileged Identity Management (PIM) is also encouraged to enable just-in-time access, limiting the duration and exposure of high-level permissions.
Endpoint management platforms are increasingly becoming high-value targets due to the level of control they provide over enterprise systems. A single misconfiguration or compromised account can grant attackers extensive control over thousands of devices. The Stryker incident serves as a critical reminder for organizations especially those in healthcare and other critical infrastructure sectors to review and harden their endpoint management configurations. Proactive security measures, combined with strong identity governance and continuous monitoring, are essential to defend against evolving attack techniques.
