Detect the use of "sc.exe" to change the startup type of a service to "disabled" or "demand"
Detects tampering of the Vulnerable Driver Blocklist registry via command line tools such as PowerShell or REG.EXE.
The Vulnerable Driver Blocklist is a security feature that helps prevent the loading of known vulnerable drivers.
Disabling this feature may indicate an attempt to bypass security controls, often targeted by threat actors
to facilitate the installation of malicious or vulnerable drivers, particularly in scenarios involving Endpoint Detection and Response

Detects the removal of folders from the "ProtectedFolders" list of of exploit guard. This could indicate an attacker trying to launch an encryption process or trying to manipulate data inside of the protected folder
Detects enabling of the "AllowAnonymousCallback" registry value, which allows a remote connection between computers that do not have a trust relationship.
Detects changes to the AMSI come server registry key in order disable AMSI scanning functionalities. When AMSI attempts to starts its COM component, it will query its registered CLSID and return a non-existent COM server. This causes a load failure and prevents any scanning methods from being accessed, ultimately rendering AMSI useless
Detects enabling TurnOffCheck which can be used to bypass defense of MSDT Follina vulnerability
Detects changes to the "ExtErrorInformation" key in order to disable ETW logging for rpcrt4.dll
Detects unauthorized modifications to the SAP Security Audit Log configuration by monitoring specific SAP system message codes (AUE, AUF, AUI, AUJ, FU0, E05) associated with audit trail changes, excluding known administrative accounts.
