Detects the download of executable, script, archive, and document file types from hosts associated with dynamic DNS services. These services are often abused by adversaries for command and control or for hosting malicious content due to their ability to frequently change IP addresses, making them harder to track and block.
Detects network requests to '/pwndrop/' URI paths, which are indicative of communication with a PwnDrp web server. PwnDrp is a tool developed for red team testing and is also known to be used for malicious activities, typically for command and control or data exfiltration.
Detects path traversal exploitation attempts
This rule detects attempts to dump the NTDS.dit database to suspicious locations. It specifically looks for ESENT event ID 325 (New Database Created) where the data contains 'ntds.dit' and the path includes common suspicious directories such as Appdata, Desktop, Downloads, Perflogs, Temp, or Users\Public.
This rule detects when the deployment of an AppX package is blocked by the local computer policy. This can indicate an attempt to install an unauthorized application that is being prevented by system controls. The rule specifically looks for EventIDs 441, 442, 453, and 454 from the Microsoft-Windows-AppXDeployment-Server event source.
This rule detects events where Windows Code Integrity blocks a file because it is disallowed for protected processes. This indicates an attempt to load or execute an unauthorized file within a protected process environment, which could be a sign of privilege escalation or an attempt to bypass security controls.
Detects reconnaissance activities targeting privileged Active Directory users or groups by monitoring Windows Security Event ID 4661. The rule specifically looks for access attempts to objects identified as privileged users or groups based on their Security Identifier (SID) suffixes or names containing 'admin'. It filters out activity from machine accounts to reduce false positives.
Detects attempts to modify the Discretionary Access Control List (DACL) of Active Directory objects, specifically looking for WRITE_DAC access (0x40000). This can indicate an adversary attempting to gain control over Active Directory objects, potentially for privilege escalation or persistence.
Detects the creation of a new service where the service file name contains patterns indicative of using `clip.exe` or similar clipboard-related utilities, often associated with obfuscated PowerShell scripts. This can be a technique used for defense evasion by adversaries.
This rule detects the creation of a new Windows service where the service executable path contains 'powershell' or 'pwsh'. This behavior is often indicative of an adversary attempting to establish persistence or elevate privileges by running PowerShell scripts as a service.
