Detects the deletion of an Active Directory Group Policy Object (GPO) by monitoring Windows Security Event ID 5141 where the deleted object class is 'groupPolicyContainer'. This activity may indicate an attempt to weaken domain security controls or impair defenses.
Detects modifications to Active Directory objects of the class 'groupPolicyContainer' by monitoring Windows Security Event ID 5136. Unauthorized or unexpected GPO modifications can be used by attackers to weaken security controls, establish persistence, or facilitate privilege escalation across a domain.
This rule detects modifications to Google Cloud Platform (GCP) Cloud DNS managed zones, including creating, deleting, patching, updating, or changing records within a managed zone. It performs triage by categorizing the actor as either a human or a service account, checks for the use of Infrastructure-as-Code (Terraform), and flags potentially anomalous activity such as service accounts interacting with DNS outside of expected networks or without using automated tooling.
This rule detects modifications or registrations of Pass-Through Authentication (PTA) agents and changes to federation settings within an identity tenant. Such actions can indicate an adversary attempting to establish persistence, bypass authentication mechanisms, or intercept credentials by manipulating the authentication infrastructure.
This rule detects modifications or registrations of Pass-Through Authentication (PTA) agents and changes to federation settings within an identity tenant. Such actions can indicate an adversary attempting to establish persistence, bypass authentication mechanisms, or intercept credentials by manipulating the authentication infrastructure.
Detects updates or deletions of Azure Active Directory (Entra ID) Conditional Access policies that occur outside of typical business hours (Monday-Friday 08:00-18:00 UTC). Such modifications can be an indicator of an adversary attempting to circumvent security controls or maintain persistent, unauthorized access.
This rule detects potentially malicious activity related to Group Policy Object (GPO) manipulation, including the execution of the SharpGPOAbuse tool and suspicious PowerShell commands intended to modify GPOs for persistence or privilege escalation, such as adding local administrators, creating immediate tasks, or applying domain-level policies.
Detects the execution of SharpGPOAbuse for malicious Group Policy Object (GPO) manipulation, specifically identifying characteristic command-line arguments used for task creation and modification. The rule also monitors for subsequent forced GPO updates via net.exe or net1.exe, often associated with post-exploitation activities in the StrikeShark campaign.
This rule monitors for two distinct behaviors: direct modification of Group Policy Object (GPO) containers within Active Directory and suspicious execution of GPO management tools (gpupdate.exe or gpedit.msc) across multiple hosts in a short timeframe. AD modification events are flagged as critical, while elevated tool execution patterns are flagged as high or medium risk based on host prevalence.
Detects updates or deletions of Azure Active Directory (Entra ID) Conditional Access policies that occur outside of typical business hours (Monday-Friday 08:00-18:00 UTC). Such modifications can be an indicator of an adversary attempting to circumvent security controls or maintain persistent, unauthorized access.
This rule monitors for unauthorized deletion or modification of Microsoft Sentinel alert rules and automation rules. Such actions are indicative of an attacker attempting to impair security monitoring, silence alerts, or disable automated responses to maintain persistence and evade detection.
Detects changes to Microsoft Entra (formerly Azure AD) Conditional Access policies. This includes additions, updates, or deletions of these security policies, which could indicate an attacker attempting to weaken authentication requirements, bypass multi-factor authentication, or establish persistence within the identity environment.
Detects changes to Microsoft Entra (formerly Azure AD) Conditional Access policies. This includes additions, updates, or deletions of these security policies, which could indicate an attacker attempting to weaken authentication requirements, bypass multi-factor authentication, or establish persistence within the identity environment.
Detects updates or deletions of Azure Active Directory (Entra ID) Conditional Access policies that occur outside of typical business hours (Monday-Friday 08:00-18:00 UTC). Such modifications can be an indicator of an adversary attempting to circumvent security controls or maintain persistent, unauthorized access.
Detects any modification (add, update, or delete) to Entra ID cross-tenant access settings. Adversaries may manipulate these trust configurations to weaken inbound security restrictions, establish unauthorized access between tenants, or facilitate cross-tenant impersonation.
This rule detects modifications to Group Policy Objects (GPOs) that involve sensitive attributes such as logon scripts, startup/shutdown scripts, or file system paths, particularly when performed by service accounts or non-administrator users. This activity is a common indicator of persistence mechanisms or lateral movement via GPO abuse.
This rule monitors for two distinct behaviors: direct modification of Group Policy Object (GPO) containers within Active Directory and suspicious execution of GPO management tools (gpupdate.exe or gpedit.msc) across multiple hosts in a short timeframe. AD modification events are flagged as critical, while elevated tool execution patterns are flagged as high or medium risk based on host prevalence.
This rule detects potential abuse of Group Policy Objects (GPOs) by identifying multiple changes (3 or more) to GPO-related objects within a short timeframe. It specifically looks for Event ID 5136 (Directory Service Changes) where the ObjectClass is either 'groupPolicyContainer' or 'gPCFileSysPath'. This could indicate an adversary modifying GPOs to achieve persistence, privilege escalation, or other malicious objectives.
This rule detects changes to the domain password policy by monitoring Windows Security Event ID 4739. It summarizes these events by the user who made the change and the time, providing an hourly count of policy modifications. This can help identify unauthorized or suspicious alterations to critical security policies.
Detects updates or deletions of Azure Active Directory (Entra ID) Conditional Access policies that occur outside of typical business hours (Monday-Friday 08:00-18:00 UTC). Such modifications can be an indicator of an adversary attempting to circumvent security controls or maintain persistent, unauthorized access.
Detects modification of domain trust relationships via LDAP for privilege escalation
