Detects known malicious service installs that appear in cases in which a Cobalt Strike beacon elevates privileges or lateral movement.
Detects execution of commands via the run dialog box on Windows by checking values of the "RunMRU" registry key.
This technique was seen being abused by threat actors to deceive users into pasting and executing malicious commands, often disguised as CAPTCHA verification steps.

Adversaries may abuse features of Winlogon to execute DLLs and/or executables when a user logs in.
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.

Adversaries may establish persistence and/or elevate privileges by executing malicious content triggered by application shims.
The Microsoft Windows Application Compatibility Infrastructure/Framework (Application Shim) was created to allow for backward compatibility of software as the operating system codebase changes over time

Detects potential persistence activity via the registering of a new custom protocole handlers. While legitimate applications register protocole handlers often times during installation. And attacker can abuse this by setting a custom handler to be used as a persistence mechanism.
Detects modification of autostart extensibility point (ASEP) in registry.
Detects an attacker trying to enable the outlook security setting "EnableUnsafeClientMailRules" which allows outlook to run applications or execute macros
Detects setting of a new registry value related to BgInfo configuration, which can be abused to execute custom VBScript via "BgInfo.exe"
Detects set value ms-msdt MSProtocol URI scheme in Registry that could be an attempt to exploit CVE-2022-30190.
Detects usage of Windows Input Method Editor (IME) keyboard layout feature, which allows an attacker to load a DLL into the process after sending the WM_INPUTLANGCHANGEREQUEST message.
Before doing this, the client needs to register the DLL in a special registry key that is assumed to implement this keyboard layout. This registry key should store a value named "Ime File" with a DLL path.
IMEs are essential for languages that have more characters than can be represented on a standard keyboard, such as Chinese, Japanese, and Korean.

Detects processes setting a new DLL in DllName in under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\W32Time\TimeProvider.
Adversaries may abuse time providers to execute DLLs when the system boots.
The Windows Time service (W32Time) enables time synchronization across and within domains.

Detects potential WerFault "ReflectDebugger" registry value abuse for persistence.
Detects tampering of RDP Terminal Service/Server sensitive settings.
Such as allowing unauthorized users access to a system via the 'fAllowUnsolicited' or enabling RDP via 'fDenyTSConnections', etc.

Detects modification of autostart extensibility point (ASEP) in registry.
Detects changes in Sysmon driver altitude value.
If the Sysmon driver is configured to load at an altitude of another registered service, it will fail to load at boot.

Detects registry value settings that would replace the user's desktop background.
This is a common technique used by malware to change the desktop background to a ransom note or other image.

Detects registry modifications that hide internal tools or functions from the user (malware like Agent Tesla, Hermetic Wiper uses this technique)
Detects modification of autostart extensibility point (ASEP) in registry.
Detect changes to the "PendingFileRenameOperations" registry key from uncommon or suspicious images locations to stage currently used files for rename or deletion after reboot.
Detects potential PowerShell commands or code within registry run keys
