Identifies instances where the 'find' command is started on a Linux system with arguments targeting
specific VM-related paths, such as "/etc/vmware/", "/usr/lib/vmware/", or "/vmfs/*".
These paths are associated with VMware virtualization software, and their presence in the find command arguments
may indicate that a threat actor is attempting to search for, analyze, or manipulate VM-related files
and configurations on the system.
