Narcos-1 C:/ Image Analysis Using Autopsy Forensic Toolkit
Introduction:
This is a basic introduction to using Autopsy to examine the contents of a criminal suspect’s
computer. While this is not a real criminal case, but a training tool, there are examples of
paraphernalia and other nefarious dealings throughout the disk image. The situation is that there is
a gang smuggling crystal methamphetamine between Australia and New Zealand. As the new intern
at a computer forensics lab, you have been tasked with finding out some basic information about the
suspect, and the data on their computer’s C: drive.
Assignment:
