What is Autopsy?

Autopsy is an open-source and powerful digital forensics platform. Several features within Autopsy have been developed by the Department of Homeland Security Science and Technology funding.

"Autopsy is the premier open source forensics platform which is fast, easy-to-use, and capable of analysing all types of mobile devices and digital media. Its plug-in architecture enables extensibility from community-developed or custom-built modules. Autopsy evolves to meet the needs of hundreds of thousands of professionals in law enforcement, national security, litigation support, and corporate investigation."

Before diving into Autopsy and analysing data, there are a few steps to perform; such as identifying the data source and what Autopsy actions to perform with the data source.

Basic workflow:

  1. Create/open the case for the data source you will investigate
  2. Select the data source you wish to analyse
  3. Configure the ingest modules to extract specific artefacts from the data source
  4. Review the artefacts extracted by the ingest modules
  5. Create the report

Case Analysis | Create a New Case

To prepare a new case investigation, you need to create a case file from the data source. When you start Autopsy, there will be three options. You can create a new case file using the "New Case" option. Once you click on the "New Case" option, the Case Information menu opens**,** where information about the case is populated.

Case Analysis | Open an Existing Case

The Autopsy can also open prebuilt case files. Note that supported data sources are discussed in the next task. This part aims to show how to create/open case files with Autopsy.

Note: Autopsy case files have a ".aut" file extension.

Note: A warning box will appear if Autopsy cannot locate the disk image. At this point, you can point to the location of the disk image it's attempting to find, or you can click NO; you can still analyse the data from the Autopsy case.
