A NetBeans module that integrates pstconv tool in Autopsy®. It provides context menu options to convert proprietary Microsoft Outlook OST/PST files to EML or MBOX format.
Autopsy® is a digital forensic application used by law enforcement, military, and corporate examiners to analyse the contents of a computer. It's built on top of NetBeans Platform, a rich client java platform that provides several APIs and a module system to help write large desktop applications, like NetBeans IDE for example. Autopsy also takes advantage of this module system to provide a set of key features such as file identification and indexing, extracting web browser bookmarks and navigation history and more.
One of the modules that is included in the default installation is the 'Email Parser' module. It can parse and extract e-mail messages in several mail box formats, such as Mozilla Thunderbird folders and PST archives and it's also possible to do some basic filtering and searching but it lacks features for advanced searching, features which are normally found on e-mail client applications such as Microsoft Outlook, Mozilla Thunderbird, Opera Mail, just to name a few. Also, Autopsy only allows to export either the full PST archive or a list of messages in CSV format, but without the full text body (only the first 160 characters), attachments and headers.
The PSTConv Autopsy Module allows to convert a Microsoft PST archive to MBOX or EML format so that it's possible to import the converted message to an e-mail client application for further analysis.
- Java Runtime Environment 17
- Autopsy 4.21.0
Download the latest version of PSTConv Autopsy Module from the Releases (the file with .nbm extension), then open Autopsy and click on the Tools -> Plugins menu item. Select the 'Downloaded' tab from the 'Plugins' window and browse to the downloaded module file by clicking on the 'Add Plugins...' button. Afterwards, hit the 'Install' button to install the module.
In order to use this plugin effectively, the user must first run the 'File Identification' module so that Autopsy calculates the mime type of each file contained in the datasource. Right-clicking on a file with "application/vnd.ms-outlook-pst" or "application/vnd.ms-outlook" mime types will popup a context menu with two additional items added by the PSConv Autopsy Module.
After selecting this menu item, a dialog is open to allow the user to specify the export parameters. By clicking on the 'Browse' button, a directory chooser dialog is open to let the user specify the output directory and it's also possible to set the output format and the character encoding to use for reading the messages text content from the PST archive.
Hit the 'Export' button to start exporting the selected PST archive with the chosen output format. It may take a while depending on the PST archive size. After the export is finished, the user can open the MBOX or EML directory and import it to an e-mail client to analyse the message contents.
This option allows to generate a listing in Autopsy with the PST messages that match the messages found on a previously exported MBOX/EML directory. After selecting this option a dialog is open to allow to user to specify the path to the exported directory and other parameters, as shown in the following figure.
By clicking on the 'Compare' button, the plugin creates a listing almost identical to the one generated by Autopsy itself when the user chooses the 'E-mail Messages' item from the case tree (the only column missing is 'Thread Id'). The plugin reads all message descriptor IDs from the 'X-Outlook-Descriptor-Id' header and compares them with the message IDs from the previously selected PST archive. If there's a match, then the message is added to the listing. This allows the user to compare the exported messages with the original PST messages if necessary, or use Autopsy to export the listing to a CSV file, for example.
