Detects execution of the builtin "rmdir" command in order to delete directories.
Adversaries may delete files left behind by the actions of their intrusion activity.
Malware, tools, or other non-native files dropped or created on a system by an adversary may leave traces to indicate to what was done within a network and how.
Removal of these files can occur during an intrusion, or as part of a post-intrusion process to minimize the adversary's footprint.
