Hey All,

I realized that my memory dump file was a little corrupt. Glad I made two (one with FTK Imager and one with WinEn): Here is my pslist:

Subject: Re: [Vol-users] Interesting finding

So the weird PID is because the pid column is fixed width for an unsigned short (since the maximum pid is 65535) however the EPROCESS.UniqueProcessId is actually defined as an unsigned int. So what happened is psscan (process pool scanner) picked up a possible structure whose UniqueProcessId value is larger than any valid PID and it gets shortened to "14...5" to fit in the column. I suppose we should fix it so that the whole unsigned int can fit even though those entries are likely to be false positives or a real EPROCESS structure but the pid member has been overritten.

But yes the False in pslist, thrdproc, etc is strange. Does the pslist command work on your image? Also can you paste the full command-line your're using (not just the output)?

Thanks,

MHL

Personally no, but they will probably more competent people who will answer.

The most surprising is not weird PID but that most processes are hidden from pslist.

Isn't it just a bug or can you tell more about the context ?
