Azure AD Phantom Device PRT CA Bypass - New Device Then Sensitive App Access
Detects a potential Conditional Access bypass, often associated with Storm-2372, where a device is registered and immediately followed by a PRT or deviceToken-authenticated sign-in to sensitive cloud applications within one hour. This behavior indicates the usage of non-TPM-attested 'phantom' devices to circumvent device-based security requirements.
