This detection rule identifies instances when the Windows Vulnerable Driver Blocklist is disabled by monitoring specific modifications to the system registry. Disabling this setting is a critical security risk as it allows the potential loading of known vulnerable drivers, thereby exposing the system to security threats. The rule is particularly important for systems running Windows 10 version 1903 or later and Windows Server 2022 or later. The driver blocklist influences the ability of users and threat actors to install malicious drivers that can be used for unauthorized access or exploitation. The configuration change necessitates a system reboot and the detection focuses on the registry change action. Given its potential implications for system security, this detection rule is classified with a high severity level, emphasizing the need for timely investigation should such a modification occur.
