Native root detection support for Microsoft Defender on Android
Root detection is a critical security control that identifies whether an Android device has been compromised to gain elevated privileges or unrestricted access to the operating system. When a device is rooted, built-in security boundaries are broken, allowing attackers or malicious applications to bypass security controls, disable protections, and manipulate sensitive system files. This permits the installation of unauthorized applications and increases the likelihood of unauthorized access to corporate data. Such devices can raise the overall risk level for an organization. That’s why we’re pleased to share that Microsoft Defender now includes built-in root detection on Android devices. This enables proactive detection of rooted devices without requiring Intune policies, ensuring stronger security and validating that Defender is running on an uncompromised device, ensuring more reliable telemetry that is not vulnerable to attacker manipulation. What’s new? Enhanced SOC visibility – See rooted devices in your environment in the Defender portal. Onboarding protection – Prevents users from onboarding Defender on rooted devices so that it can’t be manipulated by attackers. Streamlined feedback process – Allows users to directly submit feedback logs on rooted devices from the Defender app for investigation. Improved user experience – Provides clear visibility into whether root detection is active or turned off and what actions are required to activate the root detection. What protection does it bring to the customer? Previously, root detection alerts were not displayed in the security portal. With this update, Defender now detects rooted Android devices, whether they are managed or unmanaged. When a device is identified as rooted, a high severity alert appears in the Defender portal. The device is then classified as high risk and its risk score is communicated to device compliance policies. This allows organizations to block such devices from accessing corporate resources if compliance policies have been configured in the Intune portal. Additionally, analysts can investigate further to determine the scope of the issue and ensure no broader impact has occurred within the organization. Prerequisite Company portal (Intune app) must be installed, and version must be 5.0.6688.0 or higher. Root detection is on by default Admin experience High Severity Root detection alerts appear in the Incidents and Alerts sections. Click on an alert to view detailed information for investigation. Use the Devices tab under Assets to investigate impacted devices. Admins can search for specific devices and review details in Incidents, Alerts, and Device Timeline for deeper analysis. User experience If a device is detected as rooted: Defender notifies the user with a “Device is Rooted” notification. Tapping the notification or opening the app takes the user to a page stating, “Your device is rooted.” To run root detection on Defender, Company portal must be installed and version must be 5.0.6688.0 or higher User Experience when Intune Company Portal version is less than 5.0.6688.0: Defender notifies on app to update the company portal app to version 5.0.6688.0. On Dashboard screen if user clicks on device protection tile Defender will mark ‘Protection off’ for root detection, all other cases it marked as active.
