ICT600 2024 Cyber Forensics & Incident

 

2019 Narcos

 

Due to intelligence provided by the Australian government, two passengers were intercepted by Customs upon arriving in Wellington, New Zealand from Brisbane. The Intel stated that Jane Esteban and John Fredricksen may be involved in illegal activity.

 

The suspects were each searched by a customs officer. John Fredricksen’s baggage consisted of clothing, toiletries and a Windows laptop. Jane Esteban’s baggage also consisted of clothing, toiletries and a small windows laptop.

 

Upon further search of the lining of the suitcase, one kilogram of Methamphetamine was located. Both suspects were taken into separate interview rooms where they were interrogated. John Fredricksen refused to answer any questions.

 

Jane Esteban stated all she knew was that she had to deliver the suitcase to the Eastbourne library but if all else failed then they were to deliver it to 666 Rewera Avenue, Petone as told by John. Customs and police subsequently raided that address. There was nobody present at the address.

 

Customs did, however, find drugs, guns and a desktop computer in the living room of the suspect’s house.

 

You are a Customs forensics investigator. Customs officers have delivered images and memory dumps of the 2 laptops and 1 desktop computer to you. Your task is to carry out a forensic examination of John Fredricksen, Jane Esteban and the unknown suspect’s laptops and desktop computers to further understand their motives, goals and objectives. It should be noted that all three devices contain different Windows 10 builds and resulting artefacts may not be located in the same location or even be present.

ICT600 Cyber Forensics and Incident Response Assignment – V1- Last Updated February 2024

 

Suspects Descriptions

 

Personas: John Fredricksen

 

John has been communicating with Steve Kowhai (NZ dealer) via with what he believes is a secure and private chat room (Discord) to discuss his new consignment. Their chat contains information on where they are going and what he wants John Fredricksen to deliver. Furthermore, Steve shares some documents via (email, cloud, etc) that will assist with his job.

 

John Fredricksen now has enough information to concoct his plan of smuggling the 1kg of methamphetamine into New Zealand, but he needs to find some cover that can take the heat off of himself if any surprises were to happen. John identifies Jane Esteban as a regular user of his business’s product (meth) and thinks she will make a great mule for smuggling the drugs.

 

Jane Esteban

 

Jane is an undercover Australian Federal Police (AFP) officer tasked with gathering evidence about a drug ring involving John Fredricksen and his associate Steve Kowhai in New Zealand.

 

Jane will be using the following persona while working undercover. She has a terrible addiction and has been visiting John to feed her addiction, which has led to a transactional friendship with him as a result. John approaches Jane soon after discussing with Steve to convince her to assist with his job.

 

Steve Kowhai

 

Steve is a big player drug distributor/dealer in the lower north island of New Zealand and is wanting to find some quality product to expand his growing empire even more. Steve has contacted a source (John) in the US to smuggle in a taster of the product he plans to buy in larger quantities later. Steve has provided John with information about New Zealand and points on how best to smuggle the product into Wellington without raising any alarms at customs. Steve knows a thing or two about digital forensics and decided to use steganography to hide the document within a picture.

Deliverable Report Task Description

 

You should follow forensics procedures, such as taking a hash of the image before using it and checking regularly to ensure you have not modified it. You can select and use any proprietary or open source tools that you have been introduced to or find yourselves to perform the analysis and extract any evidence present.

 

Your report should detail the investigation process and the findings (including copies of relevant evidence), including obstacles and problems that you encountered and how you overcame them. You can assume that the reader has a light understanding of digital forensics, so any complicated terms/techniques/etc should be explained.

 

You must include some screenshots in your reports with the output of the tools or the processes and when necessary to support/show how you reached your conclusions. Screenshots should not be used to excess – they merely serve to demonstrate your understanding of the tools/processes and should be used to support written explanations (not in place of).

 

You will be marked based on the evidence you extract, the use of appropriate tools, the detail of the process, the explanation on its relevance to the case and documentation. Remember, you report should present the information in an unbiased way. Improper handling/validation of evidence would result in loss of marks except where accurately identified and corrected.

 

**This assignment can be accomplished either individually or in pairs.

verb tense, pronoun-antecedent agreement, correct use of parallelism, etc”.

 

B. “Provide a written description not to exceed four pages of the forensic methodology used to analyse the evidence files and obtain the results identified in the summary. The methodology does not need to provide step-by-step instructions on how software was used; however, it should provide a sufficient description for the findings to be reproduced”:

 

• A methodology explaining the forensic process of how artefacts were identified.

 

• The methodology is forensically sound and is defensible.

 

• The methodology is reproducible for other forensic examiners.

 

• The methodology and table of findings support the conclusions presented in the Narcos

 

scenario.

 

• “The written methodology is free of grammatical, syntax, and spelling errors, e.g.,

 

consistent verb tense, pronoun-antecedent agreement, correct use of parallelism, etc”.

 

C. “Provide a Table of Findings, which contains a list of recovered artefacts with forensic information to build a defensible case”. “User-produced evidence files (include name of file(s), MD5 hash, and locations(s) and comment regarding evidentiary value)”:

 

Identify relevant user account profiles and computer names associated with the

 

suspect’s computers.

 

Identify relevant web activity on each suspect’s computer.

 

Identify images that help to build a profile of the three suspects’ behaviour.
