(ProcExp: Process Explorer)

{ Viewing Parent and Child Processes }


0. Background Information
  1. http://technet.microsoft.com/en-us/sysinternals/bb896653
    • The Process Explorer display consists of two sub-windows.

     

    • The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded.

     

    • Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

     

    • The unique capabilities of Process Explorer make it useful for tracking down DLL-version problems or handle leaks, and provide insight into the way Windows and applications work.

      • Also you can see who has Permission to Full Control, Read, and Write.
    • Click on Permissions Button.

    • Save File as lsass-YYYYMMDD.dmp, where YYYYMMDD is a date field.

     

  3. Using Windows Explorer, Navigate to C:\tools\ProcExp\ProcessExplorer
    • Proof of Lab: Highlight lsass-YYYYMMDD.dmp, Do a screen print, Paste into word doc, Upload to Moodle.

     

  4. Special Note (Not required for this lab), for dumping all memory processes.
    • You would highlight System --> Create Dump --> Create Full Dump
    • From a forensics point of view, you would want to capture everything.

     

Proof of Lab
  1. Cut and Paste a screen shot that looks similar to Step #3 in Section 5 into a word document and upload to Moodle.
