The tool the IH used in this instance was Cyber Marshal's wmr (http://cybermarshal.com/index.php/cyber-marshal-utilities/windows-memory-reader).

I've looked at dumps created by this tool in the past and this type of output/behavior wasn't observed.

I've had bad memory captures look a bit like this...Can you share what tool was used to collect the memory image?

Background: The user logged off (I know, I know) of the system (WinXP) and the first responder logged back in under a different user and took the memory dump.

When running pslist against the memory dump there're 2,423 entries.  I'm seeing a lot of entries where the process starts and exits - sometimes in a row:

0x89b3f868 userinit.exe           3808    548      0 --------      0      0 2013-05-26 10:00:10 UTC+0000   2013-05-26 10:00:10 UTC+0000

and sometimes more spread out:

0x89c1da98 java.exe               4536   1368      0 --------      0      0 2013-06-01 01:23:35 UTC+0000   2013-06-01 01:26:15 UTC+0000

Example of top processes by overall count of occurrence:

$ cat pslist.txt | awk '{print $2}' | sort | uniq -c | sort -nr

    364 java.exe

    362 minituner.exe

    335 userinit.exe

    301 wmiprvse.exe

    219 cscript.exe

    192 verclsid.exe

     91 wuauclt.exe

     37 regsvr32.exe

     34 winlogon.exe

     34 csrss.exe

[snip]

I've never come across this before so I'm wondering if this could be attributed to the first responder not letting the system fully log them on prior to taking the memory dump and therefore there was a lot of still loading processes observed?
