Windows AppCertDLL Modification Via Registry — Detection Rule
This analytic detects attempts to modify AppCertDLL registry entries. Values under this registry entry are used to specify DLLs loaded by the Windows Session Manager. Such modifications can be abused by attackers to load malicious code early in the system startup process, enabling persistent malware execution with high privileges. If confirmed malicious, this behavior may lead to system compromise, persistence, and the evasion of security controls.
