Cybercop 325 - Macintosh Forensic Analysis (May 2018)

The "Cybercop (CC) 325 - Macintosh Forensics Analysis" (MFA) course provides the fundamental knowledge and skills necessary to identify and collect volatile data, acquire forensically-sound images of Apple Macintosh computers, and perform forensic analysis of the macOS operating system and application artifacts. Students gain hands-on experience scripting and using automated tools to conduct a simulated live triage. Students will use multiple methods to acquire forensically-sound images of Apple Macintosh computers and identify unique challenges that this task may present. Students will also learn how the macOS's default file system stores data, what happens when files are sent to the macOS Trash, where operating system and application artifacts are stored, and how they can be analyzed. The forensic artifacts covered include password recovery, recently-opened files and applications, encryption handling, Mail, Safari, Messages, FaceTime, Photos, Chrome, and Firefox.

Course structure:

• Performing live triage. Learn how to preserve data from systems in different states, to use commands for collecting non-persistent data, to perform basic shell scripting.
• Macintosh imaging. Understand manual and automated imaging methods and how to identify imaging challenges.
• Processing basics. Explore mounting images, viewing hidden files, and the standard OS X directory structure.
• Partitioning schemes. Learn about the Apple Partition Map, Globally Unique Identifier Partition Table, and Master Boot Record.
• Hierarchical File System+ (HFS+). Gain hands-on experience with the structure of an HFS+ formatted storage volume, as well as how files and directories are tracked and saved.
• Operating system artifacts. Understand artifacts, such as trash, login passwords, keychains, system logs, OS X related property lists, and FileVault.
• Application artifacts. Use Mail, Contacts, Safari, Calendar, Reminders, Notes, Messages, FaceTime, Photos, Chrome, FireFox, and Skype.

MFA is a four-day classroom course.
