This rule detects when a credential (password) is added to an Azure Service Principal. This activity is identified by monitoring HTTP traffic for requests to 'graph.microsoft.com' containing 'addPassword' in the URI. This could indicate an attacker establishing persistence by adding new credentials to an existing service principal.
This rule detects the delivery of a macOS Startup Item Property List (.plist) file via HTTP that contains the string "StartupParameters". This could indicate an attempt to establish persistence on a macOS system by creating or modifying a startup item.
This rule detects the creation of an XDG Autostart entry on a Linux host by looking for network traffic containing the string "/etc/xdg/autostart/" in a TCP flow to the server on port 22. This directory is commonly used for persistence by malware to automatically execute at system startup.
This rule detects network traffic on TCP port 445 (SMB) containing the string "Security Packages" in a case-insensitive manner. This pattern is often associated with the registration or use of Security Support Provider DLLs, which can be a persistence mechanism (T1547.005) used by adversaries to maintain access to a system.
This rule detects network traffic on port 445 (SMB) containing the string "TimeProviders" (case-insensitive). This pattern is indicative of a Time Provider DLL being registered for persistence, a technique used by attackers to maintain access to a system. The rule specifically looks for this activity in established TCP connections flowing to the home network.
This rule detects network traffic containing the string "/etc/udev/rules.d/" over TCP port 22 (SSH). This string is indicative of an attempt to modify udev rules, which can be used for Linux persistence by executing malicious scripts or commands when specific hardware events occur. The detection is focused on traffic flowing from the home network to a server on the home network, suggesting an internal system attempting to modify udev rules on another internal system via SSH.
This rule detects the download of installer packages (MSI, PKG, DEB, RPM) over HTTP that contain the string 'CustomAction'. This combination is often used by malicious installers to establish persistence on a system by creating custom actions that execute at specific events.
This rule detects the creation of an Emond rule on macOS systems, which can be used for persistence. It specifically looks for network traffic containing the string "/etc/emond.d/" in a TCP flow to a server on port 22 (SSH). This indicates an attempt to establish or modify an Emond rule, which allows for scheduled execution of commands or scripts.
This rule detects the delivery of a payload associated with a COR_PROFILER DLL hijacking technique. It specifically looks for HTTP traffic flowing to the client that contains both the string "COR_PROFILER" and the file extension ".dll" (case-insensitive) within the file data. This indicates an attempt to deliver a malicious DLL that could be used for persistence or privilege escalation by exploiting the COR_PROFILER environment variable.
This rule detects attempts to disable Conditional Access Policies in Microsoft 365 via the Microsoft Graph API. It specifically looks for HTTP PATCH requests to 'graph.microsoft.com' targeting the 'conditionalAccess/policies' endpoint. Such activity could indicate an attacker attempting to bypass security controls for persistence or privilege escalation.
