dissect.target

The Dissect module tying all other Dissect modules together. It provides a programming API and command line tools which allow easy access to various data sources inside disk images or file collections (a.k.a. targets). For more information, please see the documentation.

Requirements

This project is part of the Dissect framework and requires Python.

Information on the supported Python versions can be found in the Getting Started section of the documentation.

Installation

dissect.target is available on PyPI.

pip install dissect.target

This module is also automatically installed if you install the dissect package.

If you wish to use the YARA plugin (target-query -f yara), you can install dissect.target[yara] to automatically install the yara-python dependency.

Tools inside this project

target-query

target-query is a tool used to query specific data inside one or more targets. These queries are available in the form of functions that reside within plugins. Each plugin is focussed on providing specific functionality.

This functionality can range from parsing log sources, such as command history logs (i.e. bash history, PowerShell history, etc.), to returning the hostname and operating system version.

The most basic basic usage of target-query is to execute a function on a target:

target-query -f <FUNCTION_NAME> /example_path/target.vmdk

You can also use basic path expansion to execute functions over multiple targets. For example, to execute a function on all .vmdk files in a directory:

target-query -f <FUNCTION_NAME> /example_path/*.vmdk

Not every target plugin will function on every target, they are OS specific. More information on how to use target-query is found in the documentation.

target-shell

target-shell gives you the ability to access a target using a virtual shell environment. Once a shell is opened on a target, type help to list the available commands. To see the documentation of each command, you can use help [COMMAND].

Opening a shell on a target is straight-forward. You can do so by specifying a path to a target as follows:

    target-shell targets/EXAMPLE.vmx
    WIN-EXAMPLE:/$ help

    Documented commands (type help <topic>):
    ========================================
    attr   cls    enter        find     info  man       registry  volumes
    cat    cyber  exit         hash     less  pwd       save      zcat   
    cd     debug  file         help     ll    python    stat      zless  
    clear  disks  filesystems  hexdump  ls    readlink  tree    

    WIN-EXAMPLE:/$ ls
    $fs$
    c:
    efi
    sysvol

Further interacting with the target can be done using the commands listed above. You can exit the shell by running exit or by pressing CTRL+D.

More information on how to use target-shell is found in the documentation.

target-fs

With target-fs you can interact with the filesystem of a target using a set of familiar Unix commands.

The basic structure of a target-fs command is as follows:

target-fs <path_to_target> <command> <path_for_command>

NOTE: As with any shell command, you have to properly escape backlashes and spaces. Unless you use single or double quotes (', ").

More information on how to use target-fs is found in the documentation.

target-reg

With target-reg you can easily query the registry of Windows targets and print the results in a tree. A + symbol indicates that it is a registry key (i.e. may have subkeys). A - symbol indicates a registry value.

user@dissect~$ target-reg targets/EXAMPLE.E01 -k "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft"
+ 'Microsoft' (last-modified-date-shows-here)
    + '.NETFramework' (last-modified-date-shows-here)
    - 'Enable64Bit' value-shows-here
[...]

More information on how to use target-reg is found in the documentation.

target-dump

With target-dump you can export records of a specific function used in target-query to a file.

The basic structure of a target-dump command is as follows:

target-dump -f <comma_seperated_functions> <path_to_target>

Futhermore, the tool can apply certain compression algorithms to the dump, to create small archives of the output.

More information on how to use target-dump is found in the documentation.

target-dd

With target-dd you can export (a part of) a target to a file or to stdout. At the moment, target-dd can be used for targets that have only one disk.

The basic structure of a target-dd command is as follows:

target-dd --write <output_file> --offset <offset_on_target_in_bytes> --bytes <nr_of_bytes_to_read> <path_to_target>

More information on how to use target-dd is found in the documentation.

target-mount

With target-mount you can mount the filesystem of a target to any arbitrary directory on your analysis machine, similar to the mount command on Unix systems. To perform this function, we use fusepy to mount a filesystem in linux and mac. This interacts with fuselib to mount disk images in linux userspace, so no administrative access is required.

target-mount has two required positional arguments:

• TARGET - Target to mount
• MOUNT - Directory to mount the target's filesystem on

The following example command can be used to mount a target to the directory mnt:

user@dissect~$ target-mount targets/EXAMPLE.vmx ~/mnt/EXAMPLE
user@dissect~$ ls ~/mnt/EXAMPLE/
disks   fs   volumes

When mounting a target using target-mount the process is kept in the foreground. This will occupy your current terminal session. It is recommended to either open a second terminal, let this command run in the background by appending & to the command or use a terminal multiplexer like tmux to start a second session. Using one of these methods enables you to interact with the mountpoint.

More information on how to use target-mount is found in the documentation.

Build and test instructions

This project uses tox to build source and wheel distributions. Run the following command from the root folder to build these:

tox -e build

The build artifacts can be found in the dist/ directory.

tox is also used to run linting and unit tests in a self-contained environment. To run both linting and unit tests using the default installed Python version, run:

tox

For a more elaborate explanation on how to build and test the project, please see the documentation.
