Kali365 PHaaS Device Code Detection

This rule detects potential device code phishing attempts by correlating a device code flow initiated from an unmanaged/non-compliant device with a suspicious user agent (e.g., 'python-requests' or '-live') and an 'unbound' signInTokenProtectionStatus, with a subsequent 'Cmsi:Cmsi' token replay event for the same user. This combination suggests a successful device code phishing attack where an adversary has obtained and is replaying a token after the victim has authenticated.
