Authorization plugins are used to extend the authorization services API and implement mechanisms that are not natively

supported by the OS, such as multi-factor authentication with third party software. Adversaries may abuse this feature to
|

persist and/or collect clear text credentials as they traverse the registered plugins during user logon.
