RE: Computer forensics to uncover illegal internet use

[Edmond Chow <echow () videotron ca>]

Good morning Jason,

Thank-you to you and all who responded to me with their ideas.  I am
wondering if there are any reference books available that would guide me
through an investigation of this sort?  I am dealing with a case involving
the viewing of child pornographic websites so I want to be careful to follow
reference guidelines of some sort so that I don't end up in jail myself!

Any help that you can provide in the form of links to articles and/or books
on this subject would be greatly appreciated.

Regards,


Edmond

Check out INDEXVIEW.exe.  Internet explorer writes a history of all
visited sites to a file labeled INDEX.DAT.  This file is usually hidden.
Most end users are not bright enough to research thoroughly and will not
delete this file.  If they use Internet Explorer as their Browser, then
find this file and you will have your proof.  Download INDEXVIEW here =>

Additionally, SecurityFocus has a great article which describes what you
want to do:

Part 1 (for IE):  http://www.securityfocus.com/infocus/1827

Part 2 (for Firefox) http://www.securityfocus.com/infocus/1832


Good Luck.

     =|   Dear List,
     =|
     =|   I'm working on the following project and would
     =|   appreciate your views:
     =|
     =|   I have been tasked with finding out if a certain
     =|   desktop computer was used to view pornographic sites
     =|   on the internet.  This user has gone to great lengths
     =|   to try to mask his illegal activities by erasing
     =|   cookies, temp.
     =|   files and by installing anti-spyware software on his
     =|   computer.  Are there any tools that would allow me to
     =|   still uncover proof that he had accessed these sites?
     =|    So far, the tech department is telling me that he
     =|   did access illegal sites on only two dates but I
     =|   suspect that this illegal activity started many
     =|   months or years ago and it will be up to me to find
     =|   more proof.
     =|
     =|   Also, at a network level, we know his IP address but
     =|   yet my technical support department is telling me
     =|   that they cannot (either because they don't want to
     =|   or because they are not technically capable of) tell
     =|   me what internet sites this IP address has accessed
     =|   in the past.  Logically, there must be a point in the
     =|   network (on some piece of hardware) where I can
     =|   consult log files to track his activities?  Or, is
     =|   there a log file that I can consult that will tell me
     =|   what sites all my users have accessed and from what
     =|   IP address?
     =|
     =|   In terms of access to the desktop in question, I will
     =|   have full access as the computer will be in my
     =|   possession in the coming days.
     =|
     =|   Thank-you and any help that you can provide would be
     =|   most appreciated.
     =|
     =|   Regards,
     =|
