A Digital Forensics- Investigation based on Case Study’s from NIST (Lab Exercise)

Method 1: Importing customized Kali VM image

The customized Kali VM = Kali (2020.4) + tools used for completing most of the labs listed above (except p2p Data Leakage case)

• Install Virtualbox
• Import the customized Kali 2020.4. Notes: the default harddisk size is 80G.

Method 2: Installing tools using the customized script (the script ONLY is tested on Kali 2020.4)

The following script will install tools needed for completing most of the labs listed above (except p2p Data Leakage case, which has its own script described in PPTs). Please let us know if you need us to add more tools to the script.

• Install Virtualbox
• Install Kali 2020.4. Notes: Suggest You configure the disk size of Kali VM 80G because the size of each leakage cases image is 30G+
• How to run the installation script instructions, or you can simply follow the commands below

wget  https://github.com/sajinshivdas/Digital-Forensics-Lab/blob/main/Help/tool-install-zsh.sh

chmod +x tool-install-zsh.sh

./tool-install-zsh.sh

Installed tools. Note that most of the commands for tools can executed globally. Now you can skip most of tool installation steps in PPTs.

The case study is to investigate an image involving intellectual property theft. The study include

• A large and complex case study created by NIST. You can access the Scenario, DD/Encase images. You can also find the solutions on their website.
• 14 hands-on labs/topics in digital forensics

Topics Covered

The P2P data leakage case study is to help students to apply various forensic techniques to investigate intellectual property theft involving P2P. The study includes

• A large and complex case involving a uTorrent client. The case is similar to NIST data leakage lab. However, it provides a clearer and more detailed timeline.
• Solid evidence with explanations. Each evidence that is associated with each activity is explained along with the timeline.
• 10 hands-on labs/topics in digital forensics

The case study is to investigate the illegal possession of Rhino images. This image was contributed by Dr. Golden G. Richard III, and was originally used in the DFRWS 2005 RODEO CHALLENGE. NIST hosts the USB DD image. A copy of the image is also available in the repository

The case study is to investigate the harassment email sent by a student to a faculty member. The case is hosted by digitalcorpora.org. You can access the senario description and network traffic from their website. The repository only provides lab instructions.

The case study is to investigate computer memory for reconstructing a timeline of illegal data transferring. The case includes a scenario of transfer sensitive files from a server to a USB.

The case study, including a disk image provided by NIST is to investigate a hacker who intercepts internet traffic within range of Wireless Access Points.

The case study is an investigation of the Morris Worm Attacking. We are using the VM provided by SeedLab. The goal of the lab is to find all evidence related to Morris Worm attacking.

The image is created by Joshua Hickman and hosted by digitalcorpora.

The image is created by Joshua Hickman and hosted by digitalcorpora.

The dataset includes logical files extracted from a DJI controller (mobile device) and a SD card image used by the device. The Drone dataset is created by VTO Labs. The lab covers GPS investigation and cached image retrieval. Note that it is a draft. We will improve the lab later.
