## Overview

When local administrators on Microsoft Entra joined devices aren't properly managed, threat actors with compromised credentials can execute device takeover attacks by removing organizational administrators and disabling the device's connection to Microsoft Entra. This lack of control results in complete loss of organizational control, creating orphaned assets that can't be managed or recovered.

## Remediation

- [Manage the local administrators on Microsoft Entra joined devices](https://learn.microsoft.com/entra/identity/devices/assign-local-admin?wt.mc_id=zerotrustrecommendations_automation_content_cnl_csasci#manage-the-microsoft-entra-joined-device-local-administrator-role)

## Run it

The check runs as part of the whole assessment, with the ZeroTrustAssessment module installed:

```powershell
Install-Module ZeroTrustAssessment -Scope CurrentUser
Connect-Maester
Invoke-Maester -Pack ZTA -SkipBuiltIn
```

Leave out `-SkipBuiltIn` to run Maester's own checks in the same run.
