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:
Before beginning you must download (3) items from here:

• Narcos_1.aut
• autopsy.db
• Narcos-1.zip
o Unzip this file (30GB)
o Open the “Image” folder within this file
o Drag both Narcos_1.aut and autopsy.db into the “Image” folder
Load the Narcos-1 image into Autopsy and examine the contents. Do this by running Autopsy and
clicking on “Open Case”. If you point the Autopsy software at the “Image” folder in the Narcos-1 folder
that you just unzipped, you should now see the Narcos_1.aut file. Double click on it and the case will
load.
