Trusted Path Bypass via Windows Directory Spoofing

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.

Registry-Free Process Scope COR_PROFILER

Adversaries may leverage the COR_PROFILER environment variable to hijack the execution flow of programs that load the .NET CLR. The COR_PROFILER is a .NET Framework feature which allows developers to specify an unmanaged (or external of .NET) profiling DLL to be loaded into each .NET process that loads the Common Language Runtime (CLR). These profiliers are designed to monitor, troubleshoot, and debug managed code executed by the .NET CLR. (Citation: Microsoft Profiling Mar 2017) (Citation: Microsoft COR_PROFILER Feb 2013)

DMSA Service Account Created in Specific OUs - PowerShell

Detects the creation of a dMSA service account using the New-ADServiceAccount cmdlet in certain OUs. The fact that the cmdlet is used to create a dMSASvc account in a specific OU is highly suspicious. It is a pattern trying to exploit the BadSuccessor privilege escalation vulnerability in Windows Server 2025. On top of that, if the user that is creating the dMSASvc account is not a legitimate administrator or does not have the necessary permissions, it is a strong signal of an attempted or successful abuse of the BaDSuccessor vulnerability for privilege escalation within the Windows Server 2025 Active Directory environment.

Service Registry Permissions Weakness Check

Adversaries may execute their own malicious payloads by hijacking the Registry entries used by services. Adversaries may use flaws in the permissions for registry to redirect from the originally specified executable to one that they control, in order to launch their own code at Service start. Windows stores local service configuration information in the Registry under HKLM\SYSTEM\CurrentControlSet\Services

Registry Modification Attempt Via VBScript - PowerShell

Detects attempts to modify the registry using VBScript's CreateObject("Wscript.shell") and RegWrite methods embedded within PowerShell scripts or commands. Threat actors commonly embed VBScript code within PowerShell to perform registry modifications, attempting to evade detection that monitors for direct registry access through traditional tools. This technique can be used for persistence, defense evasion, and privilege escalation by modifying registry keys without using regedit.exe, reg.exe, or PowerShell's native registry cmdlets.

Winlogon Helper DLL

Winlogon.exe is a Windows component responsible for actions at logon/logoff as well as the secure attention sequence (SAS) triggered by Ctrl-Alt-Delete. Registry entries in HKLM\Software[Wow6432Node]Microsoft\Windows NT\CurrentVersion\Winlogon\ and HKCU\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\ are used to manage additional helper programs and functionalities that support Winlogon. Malicious modifications to these Registry keys may cause Winlogon to load and execute malicious DLLs and/or executables.
