What it detects

This rule identifies changes to a Windows registry policy that set the ScriptedDiagnostics TurnOffCheck value to DWORD 0x00000001. Attackers may use this setting to disable a diagnostic check that can weaken defensive behaviors. It relies on registry set telemetry matching the targeted Policies\Microsoft\Windows\ScriptedDiagnostics\TurnOffCheck key and the specific DWORD data.
