Managed service account password readable too broadly (T1555)
Accounts that don't run this service can read its password.
Why it matters
Anyone who takes over one of these accounts can authenticate as the service.
How GraphnAI finds it
It runs after every sync, on each connected domain or tenant on its own. It applies to Active Directory.
It reads:
- The directory attributes
msDS-GroupMSAMembership,objectSidandobjectClass - The privilege tier classification
Tiered Fidelity™ level: Constrained
Every finding from this check carries the Constrained level.
- TheoreticalConfigured in the directory. Nothing else checked.
- ConstrainedThis checkA constraint on it has been checked.
- ValidatedTelemetry has seen it in use.
Why there's no automatic fix
GraphnAI doesn't change who can read a managed account's password, because the wrong change stops the service.
How to fix it
Limit who can read the password to the servers that run the service.
