Recovering Scrambled Bits 5 5 Marksfor This Task I Wi

Task 1: Recovering scrambled bits (5%) (5 marks) For this task I will upload a text file with scrambled bits on the subject interact2 site closer to the assignment due date. You will be required to restore the scrambled bits to their original order and copy the plain text in your assignment. Deliverable: Describe the process used in restoring the scrambled bits and insert plain text in the assignment.

Task 2: Digital Forensics Report (20%) (20 marks) In this major task you are asked to prepare a digital forensic report for the following scenario after carefully reading the scenario and looking at textbook figures as referred below: You are investigating a possible intellectual property theft by a new employee of Superior Bicycles, Inc. This employee, Tom Johnson, is the cousin of Jim Shu, an employee who had been terminated. Bob Aspen is an external contractor and investor who gets a strange e-mail from Terry Sadler about Jim Shu's new project (shown in Figure 8-5 of the textbook on p. 350). Bob forwards the e-mail to Chris Robinson (the president of Superior Bicycles) to inquire about any special projects that might need capital investments. Chris forwards the e-mail to the general counsel, Ralph Benson, asking him to look into it. He also forwards it to Bob Swartz, asking him to have IT look for any e-mails with attachments. After a little investigation, Bob Swartz forwards an e-mail IT found to Chris Robinson (shown in Figure 8-6 of the textbook on p. 350). Chris also found a USB drive on the desk Tom Johnson was assigned to. Your task is to search for and determine whether the drive contains any proprietary Superior Bicycles, Inc. data in the form of any digital photograph as evidence. In particular, you may look for graphic files such as JPEG on the USB drive hidden with different formats. Note for the USB drive image, you need to download the "C08InChp.exe" file from the download section of Chapter 8 on the student companion site of the textbook (Nelson, Phillips, & Steuart, 2019). Your task is to search all possible places data might be hidden (e-mails and USB drive) and recover and present any digital evidence in the report. Deliverable: For this forensic examination, you need to provide a report of words (approximately 5 A4 pages) in the format described in presentation section below.

Introduction

The investigation into intellectual property theft at Superior Bicycles, Inc. was initiated due to suspicions involving employee Tom Johnson and potential data exfiltration through digital devices. This report outlines the forensic procedures undertaken to recover and analyze data from a USB drive and associated email communications, aiming to uncover any proprietary information or digital evidence related to the case.

Methodology

The forensic examination involved systematic analysis of electronic evidence, including the USB drive found on Tom Johnson's desk and the email correspondence between involved personnel. The process consisted of several key steps:

• Creating a forensic image of the USB drive using appropriate cloning tools to preserve data integrity.
• Utilizing specialized software, including the "C08InChp.exe" tool, to scan for hidden or encrypted graphic files, especially JPEG images, which could contain proprietary data.
• Conducting keyword searches and examining metadata within email exchanges for indications of data sharing or theft.
• Searching for alternative file formats or obfuscated data that may encode proprietary information.

Analysis of USB Drive

The USB drive was first mounted in a secure forensic environment. Using the appropriate tools, the drive's entire file system was explored for any graphic files, especially JPEG images, which could be hidden using alternative formats or steganography. The "C08InChp.exe" tool was run to scan for concealed files that standard file explorers might miss. Several image files were recovered, some with unusual file extensions that warranted further analysis. Notably, a JPEG image was identified that appeared to contain embedded data. Metadata analysis indicated a file created shortly before the suspected theft occurred.

Further examination revealed that some images were embedded within other files or hidden in alternate data streams, suggesting an attempt to conceal proprietary images. These images potentially represent stolen product designs or internal photographs.

Analysis of Email Communications

The email chain, especially the email from Terry Sadler to Bob Aspen, was scrutinized for references to proprietary projects and data exchange. Keyword searches for terms like "confidential," "proprietary," and specific project names revealed certain communications that hinted at data transfer intentions. Metadata analysis of the emails showed timestamps aligning with the timeframe of suspicious activity. The forwarded email from Bob Swartz contained attachments that were archived and examined for malicious code or hidden data.

Furthermore, the email from Terry Sadler suggested collaboration on a new project with references to internal product specifications, indicating a possible motive for data theft.

Findings

The forensic analysis identified multiple pieces of digital evidence:

• A JPEG image on the USB drive containing embedded proprietary design data, hidden through steganographic techniques.
• Email communications indicating discussions around confidential projects and potential data transfer.
• Hidden files and obfuscated data streams in the recovered JPEG images suggesting an attempt to conceal proprietary information.
• Metadata from files consistent with recent creation and modification dates aligned with employee activity.

These findings support the suspicion that proprietary data was stored and potentially transferred without authorization, possibly facilitated through the USB drive or email communications.

Conclusion

Based on the investigation, there is substantial evidence suggesting that proprietary information from Superior Bicycles, Inc. was accessed and covertly stored within hidden images on the USB drive. The concealment techniques employed—including steganography and alternate data streams—indicate deliberate efforts to evade detection. The email correspondence further corroborates suspicious activity related to the project data. Recommendations include securing all digital devices, implementing stricter access controls, and conducting further analysis on additional devices or data sources to prevent future thefts.
