1,155 detections

This rule detects suspicious activities related to Protected Process Light (PPL) and driver loading that could indicate privilege escalation, defense evasion, or impact. Specifically, it looks for:
1. Processes running with 'System' integrity that were initiated by a process with a lower integrity level, which could suggest an attempt to elevate privileges.
2. Driver image load events where 'ntoskrnl.exe' is the initiating process, but the driver is loaded from a location outside of the standard 'System32' or 'System32\drivers' directories. This could indicate an adversary attempting to load malicious drivers to evade detection or persist.
3. DriverLoad actions initiated by 'ntoskrnl.exe' from outside the standard 'System32' or 'System32\drivers' directories, similar to the image load events, pointing to potential malicious driver activity.

Detects the loading of `libcef.dll` by `vcpktsvr.exe` from non-standard directories. This specific DLL Sideloading behavior is a key tactic of the malware associated with the Termncolor/Colorinal malicious Python packages, where a legitimate executable is dropped into an unusual location to load a malicious DLL.

This rule detects potential DLL sideloading attempts by monitoring the loading of specific DLLs (version.dll and rtworkq.dll) from non-standard Windows system directories. It specifically looks for these DLLs being loaded by 'icardagt.exe' or 'mfpmp.exe' processes outside of 'C:\Windows\System32\' or 'C:\Windows\SysWOW64\'. This behavior is indicative of an adversary attempting to execute malicious code by tricking legitimate applications into loading their malicious DLLs instead of the legitimate ones.

Detects the suspicious loading of `vss_ps.dll` by executables that are not typically associated with the Volume Shadow Copy Service (VSS). This DLL is often abused by attackers to delete or manipulate shadow copies, which can hinder forensic investigations and data recovery efforts, commonly seen in ransomware attacks or other destructive operations. The rule filters out known legitimate processes and common program file locations to reduce false positives.

Detects DLLs loading from a spoofed Windows directory path with an extra space (e.g "C:\Windows \System32") which can bypass Windows trusted path verification.
This technique tricks Windows into treating the path as trusted, allowing malicious DLLs to load with high integrity privileges bypassing UAC.

Detects potential AppDomainManager hijacking used by the OneClik APT campaign, where legitimate .NET ClickOnce applications (ZSATray.exe, umt.exe, ied.exe) load a suspicious DLL like 'history.tlb'. This technique (T1574.014) is used to load attacker-controlled assemblies and execute malicious code.

Detects the loading of the "taskschd.dll" module from a process that located in a potentially suspicious or uncommon directory.
The loading of this DLL might indicate that the application have the capability to create a scheduled task via the "Schedule.Service" COM object.
Investigation of the loading application and its behavior is required to determining if its malicious.
