Identifies instances where VMware processes, such as "vmware-vmx" or "vmx," are terminated on a Linux system
by a "kill" command. The rule monitors for the "end" event type, which signifies the termination of a process.
The presence of a "kill" command as the parent process for terminating VMware processes may indicate that a
threat actor is attempting to interfere with the virtualized environment on the targeted system.
