Built-in Administrator password older than 180 days (T1078.001)
This is the account with RID 500, even if it has been renamed.
Why it matters
The built-in Administrator has full control of the domain. Anyone who ever copied its password can still use it.
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
objectSidandpwdLastSet
Tiered Fidelity™ level: Theoretical
Every finding from this check carries the Theoretical level.
- TheoreticalThis checkConfigured in the directory. Nothing else checked.
- ConstrainedA constraint on it has been checked.
- ValidatedTelemetry has seen it in use.
Why there's no automatic fix
Rotating the break-glass password needs a safe place to keep the new one, so it runs as a guided procedure.
How to fix it
Reset the built-in Administrator password and rotate it on a schedule.
