Task 1: Recovering scrambled bits (5 Marks)

For this task, I will upload a text file with scrambled bits on the Interact 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 Marks)

In this major task you have assumed a digital forensics investigator and asked to prepare a digital forensic report for the following scenario:

In this case, you’re examining, Randall Simpson, the CIO of Flashbills, and Sarah Jensen, the lead developer at Desert Oasis Funding, are suspected of intellectual property theft. Randall is unhappy that his share of the profits has gone down since his partner’s son was hired, and Sarah has been after the code for a new app from Flashbills. The corporate investigator is aware that the two have been calling and e-mailing each other, so he attempted to do a logical acquisition of Sarah’s TracFone (a low-cost, prepaid phone often referred to as a “burner phone”). To keep customers from switching to other plans, these phones are code-locked to prevent a USB connection and even jailbreaking. Cellebrite was able to read the SIM card data but found no text messages, SMS messages, phone numbers, or other data. Figure 12-2 shows a Cellebrite report, and Figure 12-3 shows some plists (discussed in Chapter 7) found on the device. In addition to the case legal side, the investigator was able to get a warrant for cloud backups of Randall’s and Sarah’s mobile devices.

Deliverable: For this forensic examination, you need to search all possible places data might be hiding and submit a digital forensics report of 1800-2000 words.
