What it detects

This rule detects AADInternals cmdlets that mint or export Primary Refresh Token material and device certificates for cloud identity abuse. The cloud lateral-movement research shows attackers use these to forge tokens and access cloud resources as the victim. The cmdlet names are specific to this toolkit and indicate token theft or forgery.
