Detects instances where a user within the MyBB Admin Control Panel (ACP) attempts to create a new user account and assign it to the administrator usergroup (gid=4). This activity is indicative of a privilege escalation attempt by an authenticated user with limited administrative access or an attacker who has compromised such an account.
Detects the use of the Windows net.exe or net1.exe utilities to add users to privileged groups such as 'Administrators' or 'Domain Admins'. This is a common technique used by attackers to achieve privilege escalation or establish persistence by modifying sensitive account group memberships.
Detects the use of the Windows net.exe or net1.exe utilities to add users to privileged groups such as 'Administrators' or 'Domain Admins'. This is a common technique used by attackers to achieve privilege escalation or establish persistence by modifying sensitive account group memberships.
This rule detects the rapid creation of a new user account followed immediately by that user being added to a high-privilege group (specifically those containing 'administrators' or 'remote desktop users') within a 60-second window. It monitors Windows Security event logs for Event IDs 4720 (User Account Created) and 4732 (Member added to security-enabled local group).
Detects cases where a user privilege is granted (EventCode 4717) and subsequently revoked (EventCode 4718) within a 60-minute window. This behavior often indicates transient privilege abuse, where an attacker grants themselves temporary elevated rights to perform an action and then revokes them to evade detection or minimize their footprint.
Detects cases where a user privilege is granted (EventCode 4717) and subsequently revoked (EventCode 4718) within a 60-minute window. This behavior often indicates transient privilege abuse, where an attacker grants themselves temporary elevated rights to perform an action and then revokes them to evade detection or minimize their footprint.
Detects the use of Windows Package Manager utilities (winget.exe, WindowsPackageManagerServer.exe) or ConfigurationRemotingServer.exe to execute administrative commands related to local user and group management, such as adding users or modifying group memberships. This behavior is highly irregular for these binaries and suggests potential abuse for persistence or privilege escalation.
This rule monitors for additions of users to highly sensitive Active Directory groups, such as Domain Admins or Enterprise Admins, by tracking specific Windows security events (4728, 4732, 4756). Unauthorized membership changes in these groups are a classic indicator of privilege escalation or persistence maintenance by an adversary.
This rule detects when sensitive administrative roles are assigned directly to users in Microsoft Entra ID (formerly Azure AD) without utilizing the Privileged Identity Management (PIM) service. Direct assignment of these roles bypasses the security controls and JIT (Just-In-Time) access workflows enforced by PIM, potentially indicating unauthorized privilege escalation or a misconfiguration.
Detects when an application or service principal is assigned an app role containing sensitive permissions in Azure AD/Microsoft Entra ID. Such assignments can grant an application elevated access to mail, directory, or user management, which is a common tactic for persistence and privilege escalation in cloud environments.
Detects the creation of user accounts or modifications to sensitive groups (Event IDs 4720, 4728, 4732, 4756) where the account name matches naming conventions typically associated with backup service accounts or elevated administrative roles (e.g., prefix 'backup_', 'bkp_' or suffix '_da', '_ea'). This activity can indicate an attacker attempting to establish persistence or escalate privileges via compromised or newly created accounts.
Detects instances where a user or service principal is assigned to high-privilege roles (e.g., Global Administrator, Owner) without utilizing the Microsoft Entra Privileged Identity Management (PIM) service. This is indicated by the absence of 'PIM' in the LoggedByService field for a successful 'Add member to role' operation, which could signify an attempt to bypass established access controls and gain unauthorized elevated persistence.
Detects potential privilege escalation attempts against a MyBB forum by monitoring POST requests to administrative endpoints. Specifically, it flags session activity that includes creating new users with admin group assignments (usergroup=4) or accessing sensitive administrative modules (config, tools, style, user) from within the admin control panel.
Detects unauthorized attempts to escalate privileges within the MyBB Admin Control Panel (ACP) by creating a new user account with administrator privileges (group 4). This rule identifies when an account with limited management permissions exploits the ACP to assign a new user to the administrator group, effectively bypassing intended permission restrictions.
Detects unauthorized privilege escalation attempts within the MyBB Admin Control Panel (ACP). The rule identifies HTTP POST requests, likely generated by a limited-privilege account, that attempt to create a new user with Administrator permissions (gid=4) or modify an existing user's group assignment to the Administrator group, bypassing standard ACP permission controls.
This rule detects the execution of 'net.exe' or 'net1.exe' by 'powershell.exe' to perform potentially malicious Active Directory administrative tasks. Specifically, it monitors for commands related to creating or modifying domain users, adding users to privileged groups such as 'Enterprise Admins', or configuring backup accounts, which are common patterns for persistence and privilege escalation.

Specifically, it monitors for commands related to creating or modifying domain users, adding users to privileged groups such as 'Enterprise Admins', or configuring backup accounts, which are common patterns for persistence and privilege escalation.
Detects the addition of users to specific high-value or sensitive groups in Microsoft Entra ID (Azure AD), which could indicate potential unauthorized privilege escalation or persistence attempts by an attacker.
Detects users who modify their MFA settings (registration/update/delete) and subsequently perform privileged actions (such as adding role members or service principal credentials) within a short timeframe, while simultaneously observed active in communication applications like Teams, Zoom, or Webex. This behavior is indicative of potential account takeover where an adversary modifies authentication methods to gain persistent access, followed by privilege escalation.
Detects execution of Azure Automation runbook jobs by managed identities that have recently been assigned high-privilege roles (Owner, Contributor, or User Access Administrator). This behavior is indicative of potential privilege escalation or abuse of existing high-privilege identities to execute unauthorized automation tasks.
