The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a new advisory urging organizations to strengthen the security of endpoint management platforms, particularly Microsoft Intune, after a recent cyberattack targeting medical technology company Stryker Corporation. The alert, published on March 18, 2026, highlights a growing trend of threat actors targeting enterprise endpoint management systems to gain elevated access and disrupt operations. The warning follows a cyber incident on March 11 that affected Stryker’s Microsoft environment, leading to network disruptions and an ongoing investigation. While technical specifics of the attack have not been fully disclosed, CISA noted that attackers are increasingly exploiting legitimate administrative features within endpoint management tools rather than relying solely on malware or traditional vulnerabilities. By leveraging these built-in capabilities, adversaries can operate under the guise of normal administrative activity, making detection significantly more challenging.

CISA emphasized that this approach reflects a broader shift toward “living-off-the-land” tactics, where attackers misuse trusted system tools to execute malicious actions By compromising privileged accounts or exploiting misconfigured roles, threat actors can deploy harmful scripts, modify configurations, wipe devices, or move laterally across networks without triggering standard security alerts. The agency is working alongside federal partners, including the FBI, to further investigate the incident and assess the wider threat landscape. Officials warn that similar attack methods could impact organizations across multiple sectors, particularly those with weak access controls or excessive administrative privileges. To reduce risk, CISA is encouraging organizations to adopt Microsoft’s latest security best practices for Intune and related identity systems.

Organizations should enforce least privilege access by implementing role-based access control (RBAC), ensuring administrators only have the permissions necessary for their specific roles. Strengthening security further requires phishing-resistant multi-factor authentication (MFA), supported by conditional access and risk-based policies to protect privileged accounts. High-risk actions should be safeguarded through multi-admin approval (MAA), adding an extra layer of authorization. Adopting a Zero Trust approach helps continuously verify identities and enforce strict access controls, while privileged identity management (PIM) enables just-in-time access to minimize exposure of sensitive privileges. Additionally, robust monitoring and auditing practices are essential to maintain visibility into administrative activities and enable faster threat detection and response.

CISA’s advisory reflects a broader shift in attacker strategy, where identity systems and centralized management platforms are becoming primary targets. Since these systems act as control hubs for enterprise environments, a single compromise can have widespread consequences across networks. The Stryker incident serves as a reminder that securing endpoint management platforms is critical. Organizations are encouraged to proactively review their configurations, strengthen access governance, and implement continuous monitoring to defend against increasingly sophisticated attack techniques.
