What it detects

This rule identifies when the MiniNt registry key default value is added under HKLM\System\CurrentControlSet\Control\MiniNt, indicating an attempt to disable Windows Event Log behavior after reboot. Disabling event logging impairs auditing and can reduce the visibility of attacker activity that would otherwise be recorded. It relies on registry set telemetry capturing the TargetObject path for the write operation.
