This detection rule identifies modifications to the Windows registry which disable the SmartScreen prompt via the `PreventSmartScreenPromptOverride` registry setting. Utilizing Sysmon Event IDs 12 and 13, it looks for instances where this registry value is set to `0x00000000`, indicating the feature has been turned off. Such an action poses a significant security risk as it could potentially allow users to bypass critical security prompts, increasing exposure to malicious content. The rule is critical since SmartScreen serves as a protective mechanism against deceptive websites and downloads. Monitoring changes to this specific registry key can help security teams identify attempts to weaken endpoint defenses, thus maintaining robust security posture.
