A hex editor can be used to directly store data directly onto this slack space, as will be demonstrated in this exercise. This slack space can only be used if the file saved in that sector is made large enough to take up all of the space in the sector. This is the space on a disk that is unused when a file smaller than a sector is saved into that sector. The idea is that there is lots of slack space (shown as dots using the hex editor tool) on the storage device that runs to the end of the sector that the file is saved in. Also, the hex editor should demonstrate that hidden data can be stored onto the storage device without actually saving as a file in the operating system. A hex editor will be used to compare the two files to find the exact differences. The lab will be using a hash value to find initial evidence of tampering within a file. This lab will also demonstrate how data can be modified within a file or hidden on a disk without the data being saved as a file. The purpose of this lab is to demonstrate the use of a hex editor and hash tool in computer forensics.

Imagine that an IT department has an FTP server on an IBM server that they use to share source code between other departments within the organization in various locations throughout the US on the same LAN/WAN. Because of that, a port scanner/listener must be used to determine if/what ports are actively carrying traffic. Because of sophisticated Trojans, it could be hard for a virus detection program to detect the problem. The purpose of this lab is to demonstrate how an attacker could exploit a machine and obtain access to a server with a filtered port by piping another unfiltered port. Most of the tools used for this lab exercise is freely available for non-commercial testing purposes and opensource software, either freeware or shareware. If you need further assistance, contact the GSA. If you would like to do the exercise in your own computer the installation instructions are given in the Appendix.

The tutorial has been setup for all of the exercises and the required executables are accessible through linked short-cuts on the desktop of the administrator (no password needed to logon).
Open-source forensic tools will be introduced and demonstrated for each exercise. This tutorial session will cover data storage and access, bypassing filtered ports, reviewing Internet activity, and the use of steganography. The second is to demonstrate some of the mechanisms used by malicious attackers as well as forensic experts to disrupt computer networks and manipulate information access. The first is to introduce you to some of the tools and techniques used for forensic analysis. The objective of this tutorial is twofold.
