Detects the creation of a new local user account followed by its immediate addition to the Administrators or Remote Desktop Users groups, a common pattern observed in post-exploitation activities related to CVE-2019-0708 (BlueKeep) for achieving persistent administrative access.
Detects anomalous process execution (cmd.exe or powershell.exe) initiated by PaperCut application server processes (pc-app.exe or java.exe), followed immediately by the modification of the 'Domain Admins' group membership. This behavior is indicative of potential post-exploitation privilege escalation activity following a successful PaperCut authentication bypass.
This rule detects potential exploitation activities targeting Atlassian Confluence by monitoring for unauthorized access to administrative configuration actions (e.g., setup/setupadministrator.action) and the subsequent addition of accounts to the 'confluence-administrators' group. It correlates process execution, network request patterns, and local user account modifications to identify successful or attempted privilege escalation and configuration manipulation.
Detects suspicious activities in GitHub audit logs that could indicate RepoJacking or SkillJacking attempts, specifically focusing on repository ownership transfers, default branch modifications, repository deletion, and changes to organizational membership or roles.
Detects user creation, capability granting, or role modification events occurring on WordPress sites where the Admin Menu Editor plugin (versions 2.35 or 2.36) is active and the associated user account has administrator privileges. This pattern is often indicative of exploitation of known vulnerabilities in this specific plugin to perform unauthorized administrative actions.
Detects high-risk account modifications, such as adding MFA methods or OAuth consent grants, occurring shortly after a user sign-in. This pattern is indicative of post-AiTM session theft (e.g., NovaCookies) where an adversary uses a stolen session token to modify account settings for persistence or MFA bypass.
Detects when a user who has successfully authenticated to a system is subsequently added to the 'Domain Admins' group within a 15-minute window. This behavior often indicates an adversary performing privilege escalation after gaining initial access to an account.
This rule detects administrative SQL statements (ALTER ROLE, CREATE ROLE, or GRANT) that assign the REPLICATION attribute to a database role. The REPLICATION attribute in PostgreSQL allows a user to initiate streaming replication and perform logical decoding. This is a security-sensitive privilege, as users with this attribute can potentially bypass standard access controls or, if the environment is misconfigured or vulnerable (e.g., CVE-2026-6471), potentially leverage malicious replication plugins to achieve arbitrary code execution.

This pattern is indicative of post-AiTM session theft (e.g., NovaCookies) where an adversary uses a stolen session token to modify account settings for persistence or MFA bypass.
Detects when an AI agent (agentic identity as identified by Entra ID agentType) is added to a group. This activity could represent legitimate provisioning of agent-based workflows, but if unexpected, it may indicate potential privilege escalation or persistence via group-based role assignments.
Detects role assignments made directly by a user, bypassing PIM workflow direct assignments are permanent, don't require approval, and don't expire
Detects the creation of a new domain user followed by its addition to sensitive, high-privileged groups (e.g., Domain Admins, Enterprise Admins) using the native Windows net.exe or net1.exe utilities. This pattern aligns with known post-compromise activity observed in campaigns like Bumblebee, AdaptixC2, and Akira ransomware, where attackers create stealthy, elevated accounts (e.g., masquerading as backup service accounts) to maintain persistence and full domain control.
Okta Administrative Privilege Grant
Cortex XDR
Detects administrative privilege grants to users or groups within Okta, including standard privilege grants and custom admin role bindings. This activity is often associated with account takeovers where an attacker attempts to escalate privileges or configure rogue IdP federation to maintain persistent access.
Detects the use of 'net.exe' or 'net1.exe' to add a user to the 'Enterprise Admins' group, which is a highly privileged Active Directory group. This activity is indicative of privilege escalation and persistence attempts by an adversary to gain full control over the domain.
Windows AD User Added to Monitored Group
Cortex XDR
Detects Windows Security events (Event IDs 4728 and 4756) where a member is added to a sensitive or privileged Active Directory domain global or universal security group. The rule compares the target group against a locally maintained inventory of monitored groups to identify potential unauthorized privilege escalation or persistence.
This rule detects the creation of a new WordPress administrator account within a short window (15 minutes) of an anomalous authentication or registration event on the same account or session. It is designed to identify post-exploitation activity, specifically persistence mechanisms following the exploitation of web application vulnerabilities like arbitrary file uploads or authentication bypasses in WordPress plugins.
