This rule detects potential browser-based credential and session theft by monitoring for a process that accesses multiple sensitive web browser artifacts (cookies, local state, session storage) across several user profiles in a short timeframe. It correlates this activity with the subsequent creation of a compressed archive in a temporary directory followed by an outbound network connection, indicating a multi-stage exfiltration workflow.
Detects successful authentication attempts using legacy (basic) protocols that do not enforce modern Conditional Access policies (e.g., MFA, device compliance). The rule specifically flags these events if the originating IP address or geographic location is not observed in historical sign-in activity for the specific user, which may indicate account compromise via credential theft.
Detects impossible travel sign-in events where a user authenticates from geographically distant locations within a short time window. The rule specifically flags the second, suspicious event as having occurred via a non-interactive session or single-factor authentication, suggesting the use of a replayed or stale session token to bypass MFA.

This rule detects administrative changes that weaken cloud identity security, specifically the disabling of Entra ID Security Defaults, per-user MFA enforcement, or tenant-wide authentication-methods policies. These actions remove critical second-factor authentication requirements, significantly increasing the risk of unauthorized access via password-spraying or credential-stuffing attacks.
This rule detects instances where a user successfully activates a privileged role via Privileged Identity Management (PIM) in a cloud environment, despite the activation policy requiring approval. It flags cases where the 'Add member to role completed' event indicates that approval is required, but the 'approvalStatus' is absent, suggesting an attempt to bypass the formal approval workflow.
Detects the reactivation of a service principal by correlating the addition of new credentials followed by a successful login event for the same principal within a 7-day window. This behavior is indicative of potential persistence maintenance or account hijacking, especially when legacy or deprecated accounts are targeted.
Detects the addition of a federated identity credential to an Azure AD / Entra ID application. Adversaries may use this technique to establish persistent, secretless access to an application's service principal by configuring trust with an external OIDC issuer under their control (e.g., a malicious GitHub repository or personal OIDC provider).
Detects potential abuse of Azure Cloud Shell backing storage (acsCloudShell) to stage or persist malicious scripts following an Azure AD session compromise. Adversaries may use this storage to blend in with legitimate engineering operations while maintaining persistent access to their tooling.
