Detects registry persistence technique using the GlobalFlags and SilentProcessExit keys
Detects modification of autostart extensibility point (ASEP) in registry.
ServiceDll Hijack
Sigma
Detects changes to the "ServiceDLL" value related to a service in the registry.
This is often used as a method of persistence.

Detects when an attacker tries to disable User Account Control (UAC) notification by tampering with the "UACDisableNotify" value.
UAC is a critical security feature in Windows that prevents unauthorized changes to the operating system. It prompts the user for permission or an administrator password before allowing actions that could affect the system's operation or change settings that affect other users.
When "UACDisableNotify" is set to 1, UAC prompts are suppressed.

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 changes to the Netsh registry key to add a new DLL value that is located on a suspicious location. This change might be an indication of a potential persistence attempt by adding a malicious Netsh helper
Detect modification of TreatAs key to enable "rundll32.exe -sta" command
Detects the setting of the REGISTERAPPRESTART compatibility layer on an application.
This compatibility layer allows an application to register for restart using the "RegisterApplicationRestart" API.
This can be potentially abused as a persistence mechanism.

Detects potential persistence using Appx DebugPath
Detects changes to the PSFactory COM InProcServer32 registry. This technique was used by RomCom to create persistence storing a malicious DLL.
This rule detects a DHCP server in which a specified Callout DLL (in registry) was loaded
This rule detects a DHCP server error in which a specified Callout DLL (in registry) could not be loaded
Detects a user certificate that was valid but could not be mapped to a user in a strong way (such as via explicit mapping, key trust mapping, or a SID)
This could be a sign of exploitation of the elevation of privilege vulnerabilities (CVE-2022-34691, CVE-2022-26931, CVE-2022-26923) that can occur when the KDC allows certificate spoofing by not requiring a strong mapping.
Events where the AccountName and CN of the Subject do not match, or where the CN ends in a dollar sign indicating a machine, may indicate certificate spoofing.

Detects that a vulnerable Netlogon secure channel connection was allowed, which could be an indicator of CVE-2020-1472.
Detects service creation from KrbRelayUp tool used for privilege escalation in Windows domain environments where LDAP signing is not enforced (the default settings)
Detects PDQDeploy service installation on the target system.
When a package is deployed via PDQDeploy it installs a remote service on the target machine with the name "PDQDeployRunner-X" where "X" is an integer starting from 1

Detects a service installed by a client which has PID 0 or whose parent has PID 0
Detects suspicious service installation commands
Detects service installation with suspicious folder patterns
Detects a ProcessHacker tool that elevated privileges to a very high level
Detects suspicious service installation scripts
