Device registration within 10 minutes of device-code sign-in (PRT persistence)
This rule detects scenarios where a user completes a device-code authentication flow, followed immediately (within 10 minutes) by the registration of an unmanaged, non-compliant device to their account. This behavior is indicative of potential token theft (e.g., EvilTokens) where an adversary uses a stolen token to register their own device as a persistent, unmanaged entity, bypassing standard corporate device enrollment controls.
