Edmond,

You cannot 'investigate' viewing of child pornographic material without violating the very same laws that you are informed may have been violated by the employee of your company who stands accused.

You must stop your work immediately. Do not begin your work if you have not already, and get your company to turn the hard drive and other details over to the corporate attorney.

What you must understand is that certain persons have a legal obligation to report any finding of evidence of child pornography, but that your company and its employees, in the employees' professional capacity, may not have an obligation to report to law enforcement.

The company is typically allowed to simply wipe the hard drive of any computer that may have been used to view child pornography, and take whatever internal disciplinary action it deems appropriate with respect to the accused employee.

Only your company's attorney can guide you properly, and you are completely wrong to want to investigate this yourself.

Your company's attorney should advise you that the best thing to do is wipe the drive, and get on with the business that you are in.

If you report this to law enforcement, the employee WILL go to prison. Innocent or not.

If the employee goes to prison and is innocent, or is even accused publicly and is innocent, and eventually finds a way to prove his innocence, your company will be sued. The employee will win the lawsuit. Your company may go out of business over its improper handling of this incident.

Please feel free to contact me directly to discuss this matter in more detail. This is an area of criminal computer forensics with which I have much experience.

Sincerely,

Jason Coombs

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 =>
http://superwebsearch.com/dwl/IndexView.exe

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,
     =|
     =|
     =| Edmond
     =|
