description: This rule detects the creation of a file with the ".dmp"/".hdmp" extension by a shell or scripting application such as "cmd", "powershell", etc. Frequently created by software during a crash. Memory dumps can sometimes contain sensitive information such as credentials. It's best to determine the source of the crash.
