+  The following analytic identifies the execution of ping sleep batch commands.
   It leverages data from Endpoint Detection and Response (EDR) agents, focusing on
   process and parent process command-line details. This activity is significant as
   it indicates an attempt to delay malicious code execution, potentially evading detection
