This rule monitors the Microsoft IIS worker process (w3wp.exe) for the spawning of suspicious child processes often associated with web shell activity, such as command shells (cmd.exe, powershell.exe) or compiler/utility tools (csc.exe, cvtres.exe, rundll32.exe, regsvr32.exe). It further filters for command lines containing Exchange or OWA-related strings, and flags executions containing known web shell indicators (e.g., VIEWSTATE, GhostWebShell, reGeorg).
