BYPASSING ENROLLMENT RESTRICTIONS TO BREAK BYOD BARRIERS IN INTUNE

Summary from the TLDR InfoSec newsletter

Administrators can configure Intune to block bring your own device (BYOD) enrollment using the device enrollment restriction, which can prevent attackers from enrolling rogue devices after stealing login credentials. If personal devices are allowed for other operating systems (such as Android), attackers can send the Entra join request as that OS and then check in and complete enrollment as Windows. Otherwise, attackers can manipulate the check in XML to mock a device ID or mock Azure Virtual Desktop.
