Detection rule
Account manipulation detection (T1098)
Password reset or account enabled by another account. GraphnAI raises an alert when it sees this in your domain controllers' security events.
How GraphnAI finds it
An OpenTelemetry collector sends the Windows Security log from your domain controllers to your GraphnAI server. GraphnAI checks each batch of events against every active rule.
This rule reads 2 events:
- 4722A user account was enabled
- 4724An attempt was made to reset an account's password
One matching event raises the alert.
The alert shows the account's type and tier, and how many of its paths to Tier 0 are Validated.
Tiered Fidelity™ level: Validated
Telemetry saw the activity itself, so GraphnAI marks the changed account and the account that acted with an alert edge at the Validated level.
- TheoreticalConfigured in the directory. Nothing else checked.
- ConstrainedA constraint on it has been checked.
- ValidatedThis alertTelemetry has seen it in use.
How you respond with Select Fire™
From the alert, Select Fire opens on the account that acted. You simulate a change there before you authorize it.
- Full-AutoThis kind of alert also has harmless causes, so triage never acts on it automatically.
- A person decidesQuarantine the accountOn the account that acted.
