    Question Here have a look at this hard drive

    This was the statement made to me by my boss. What is interesting is I am a newbie when it comes to forensics, so lets get to this. The chain of evidence has been preserved I have an image of the hard drive and the original is locked in a lawyers safe. So that is not an issue. The system was not properly handled because it was a laptop and the user "turned it in" before he left, so it has been rebooted......Nothing I can do there.
    The drive has 2 partitions on it a Win2k and a linux (Red Hat). Now I have gone through the tutorials and I plan on using the tools recommended (awesome info guys thanks) to analyze the Win2k partition, however, I get a sneaking suspicion that if this character was doing anything it was while in Linux. The first step is to get past the password. I am researching that today and hope to have it solved by the time you read this.
    My question is are there freeware forensic tools that can give you the same type of information as those tools created for Windows?

    you can just boot with knoppix or so and remove the password string in /etc/shadow of the root account, now you would have access to the system as root...

    this should work, unless there is some kind of security which prevents the root account from having an empty password...

    There's a thing out on the BugTraq forensics list right now about Knoppix not being sound with regard to forensic investigation.... Unfortunately I can't seem to find it right now..... You might want to look into it......

    [Edit]

    Search Bugtraq for this thread:-

    Re: Re: Write protection devices was: Imaging speed - USB, IDE, laptop

    I'm pretty sure this is the one where a CD run Knoppix isn't forensically "sound"

    This would make any evidence you gleened from the drive in admisable in a court of law. You have just let the bad guy off. Because you have changed the drive contents.

    Jinxy, notice he said he had an IMAGE of the drive, so he can mess with it all he wants and find information however he wants then he will know the location of everything on the physical drive when it comes time for him to deal with it.

    How was that image aquired. Im not an expert on the subject, but i have read alittle resently. It would seem that it is very difficult to get the courts to exept this type off evidence. That is why software like Encase is so expencive.

    Knoppix is definitely not forensically sound as it attempts to automount available partitions (and for a couple other reasons too). A good forum for linux-related forensics (tools and otherwise) is http://www.linux-forensics.com which coupled with the forensics securityfocus mailling list should get you started off on the right foot.
