+description: This search looks for flags passed to bcdedit.exe modifications to the
+  built-in Windows error recovery boot configurations. This is typically used by ransomware
+  to prevent recovery.
+how_to_implement: You must be ingesting endpoint data that tracks process activity,
+  including parent-child relationships from your endpoints to populate the Endpoint
+  data model in the Processes node. Tune based on parent process names.
