What it detects
This rule flags Windows registry modifications that disable CrashDump by setting a DWORD value (0x00000000) under SYSTEM\CurrentControlSet\Control\CrashControl. Disabling crash dumps can reduce available forensic artifacts and impair incident response after malicious activity. The detection relies on registry-set telemetry that records the TargetObject path and the changed Details value.
