Entra ID Protection User Alert and Device Registration

Identifies sequence of events where a Microsoft Entra ID protection alert is followed by an attempt to register a new device by the same user principal. This behavior may indicate an adversary using a compromised account to register a device, potentially leading to unauthorized access to resources or persistence in the environment.

Entra ID Protection Alerts for User Detected

Identifies more than two Microsoft Entra ID Protection alerts associated to the user principal in a short time period. Microsoft Entra ID Protection alerts are triggered by suspicious sign-in activity, such as anomalous IP addresses, risky sign-ins, or other risk detections. Multiple alerts in a short time frame may indicate an ongoing attack or compromised account.

Entra ID Protection - Risk Detection

Identifies Microsoft Entra ID Protection sign-in risk detections triggered by a range of risk events such as anonymized IP addresses, password spray attacks, impossible travel, token anomalies, and more. These detections are often early indicators of potential account compromise or malicious sign-in behavior. This is a promotion rule intended to surface all Entra ID sign-in risk events for further investigation and correlation with other identity-related activity. This is a building block rule t

Entra ID Protection Admin Confirmed Compromise

Identifies when an administrator has manually confirmed a user or sign-in as compromised in Microsoft Entra ID Protection. This indicates that an administrator has reviewed the risk detection and determined that the user account or sign-in activity is definitively compromised. This is a high-confidence indicator of account compromise and should be investigated immediately.

Entra ID High Risk Sign-in

Identifies high risk Microsoft Entra ID sign-ins by leveraging Microsoft's Identity Protection machine learning and heuristics. Identity Protection categorizes risk into three tiers: low, medium, and high. While Microsoft does not provide specific details about how risk is calculated, each level brings higher confidence that the user or sign-in is compromised.

Entra ID Service Principal Credentials Created by Unusual User

Identifies when new Service Principal credentials have been added in Microsoft Entra ID. In most organizations, credentials will be added to service principals infrequently. Hijacking an application (by adding a rogue secret or certificate) with granted permissions will allow the attacker to access data that is normally protected by MFA requirements.

M365 Entra ID Risk Detection Signal

Identifies Microsoft Entra ID (formerly Azure AD) risk detection signals including risky sign-ins, compromised credentials, impossible travel, and other identity-based anomalies. These events indicate potential credential compromise, account takeover attempts, or suspicious authentication patterns detected by Microsoft's identity protection. This building block rule generates security events for correlation, threat hunting, and telemetry collection to support detection of credential access and i
