+description: The following analytic identifies a renamed instance of hh.exe (HTML Help) executing a Compiled HTML Help (CHM).
+  This particular technique will load Windows script code from a compiled help file. CHM files may contain nearly any file type embedded, but only execute html/htm.
+  Upon a successful execution, the following script engines may be used for execution - JScript, VBScript, VBScript.Encode, JScript.Encode, JScript.Compact. Analyst may identify vbscript.dll or jscript.dll loading into hh.exe upon execution.
+  The "htm" and "html" file extensions were the only extensions observed to be supported for the execution of Shortcut commands or WSH script code.
+  During investigation, identify script content origination. Validate it is the legitimate version of hh.exe by reviewing the PE metadata. 
+  hh.exe is natively found in C:\Windows\system32 and C:\Windows\syswow64. 
+how_to_implement: To successfully implement this search you need to be ingesting information
+  on process that include the name of the process responsible for the changes from
+  your endpoints into the `Endpoint` datamodel in the `Processes` node.
