    If you have another NT box, you could try using "forensictoolkit20.zip"
    or similar tools to look for deleted files and the like; just don't
    do this on your master copy, since NT will want to be able to write
    on the disks. You could in principle use the NTFS driver in Linux also
    but that would require putting a copy of linux on your box and adding
    the NTFS support (which is not default present on the dists I use).
    
    You can of course look for textual patterns by grepping the raw partition
    in the occasional case where that is enough.
    
    Have a look on securityfocus.com and packetstormsecurity.org and a few
    forensics sites like
    http://www.cybersnitch.net/tucofs/tucofs.asp?mode=mainmenu
    and http://www.dmares.com/maresware/forensic_tools.htm (to name a couple)
    for such tools. 
    
    In a mixed shop I prefer to have at least a separate disk with bootable
    NT or W2K on it in addition to a Linux disk so I can access disk images.
    You need something that understands the file structure to be able to 
    look for what went wrong in a finite time. The least costly way may be
    to just get an old box, throw Linux on it, and build as many filesystem
    support pieces as possible. Linux filesystem reading utilities exist for
    an astounding variety of filesystems. Many are unable to write, or unsafe
    for writing, but that is less important than the reading they CAN do.

    Subject: NTFS forensic analysis on Unix platform
    
    
     Hi.
    
     I have taken 2 disk images from a compromised IIS system. 
    These images are in NTFS format, and I was wondering if 
    anyone knows of an open source tool which is capable of 
    accessing these partitions. The Unix platform that I have 
    available is OpenBSD; so I can't mount the NTFS partitions.
    
     In the past I've used tct; but unrm doesn't currently 
    support ntfs filesystems.   
    
     Any advice would be greatly appreciated. 
    
    thanks,
    Marty.
