Hoarder

Hoarder is a script made to collect and parse the most valuable artifacts for forensics or incident response investigations rather than imaging the whole hard drive

Executable Releases:

You may find the latest windows binary release here

Note on 32-bit release: as of Hoarder 4.0.0, the 32-bit binary is no longer released. If you want to collect artifacts from a 32-bit endpoint, you can refer to the latest 32-bit release. You can then use kuiper or MasterParser to parse the collected artifacts.

Usage

Hoarder parses the configuration Hoarder.yml and produces an extensive help message for ease of use.

Examples

Let's say you want to collect all of the artifacts specified in Hoarder.yml then all you need to do is:

> .\hoarder.exe --all or > .\hoarder.exe -a or simply > .\hoarder.exe :).

After the script finishes, it will generate a zip file called <HOSTNAME>.zip containing all of the artifacts in addition to hoarder.log that contains the script debugging logs (a JSON log will also be packaged in the .zip results).

To collect all artifacts with the group tag parsing, run the following command: > .\hoarder.exe -g parsing

To run hoarder to collect Ntfs and Events artifacts, run the following command: > .\hoarder.exe --Ntfs --Events

Note: you can combine multiple groups, multiple artifacts, or even groups and artifacts, and expect hoarder to come up with a unique set of all artifacts you want to collect.

Configuration (Hoarder.yml)

Hoarder comes with the default configuration, Hoarder.yml.

1. If you are running from the the binary executable: Hoarder.yml default configuration is embedded in it. If you place your own Hoarder.yml next to hoarder.exe it will use it instead of the default configuration.
2. If you are running from source: you can modify Hoarder.yml or rename it and name your own configuration Hoarder.yml.

Add an Artifact to Hoarder.yml

Tip: Refer to the default configuration for reference

File and Folder Artifacts

The following is an example of file or folder collection and parsing:

  Events: 
      output: 'Events'
      path32: '\windows\system32\winevt\Logs\'
      path64: '\windows\system32\winevt\Logs\'
      files: '*'
      groups: 
      - 'parsing'
      - 'playbook1'
      - 'logs'
      parsers: '<|parsingdir|>MasterParser.exe -p winevents -i <|path|.*> -o <|output|evtx.json>'
      description: 'Windows event logs'

• Events : This is the name of the artifact. This name will be used as an argument in the hoarder command line.
• output : This is the name of the output folder for this artifact.
• path32 : The path to the artifact for 32bit systems, you can use * as widecard, and ** as recursive.
• path64 : The path to the artifact for 64bit systems, you can use * as widecard, and ** as recursive.
• files : The file name/s. it could be a single string or a list as the example above, also you can use * as widecard.
• [Hoarder 4.0.0 and above] groups: groups are like tags and each artifact can be set to be part of one or more groups. In hoarder command line, one or more group(s) can be chosen and the artifacts tagged by this group will be used. If an artifact is chosen (e.g. --Ntfs) and a group is chosen (e.g. -g playbook), hoarder will process both.
• [Hoarder 4.0.0 and above] parsers: One or more parsers to run for this artifact.
  • It can be one parser. Example:

    parsers: '<|parsingdir|>MasterParser.exe -p mft -i <|path|$MFT> -o <|output|mft.json>'

It can also be a list. Example:

    parsers:
     - '<|parsingdir|>MasterParser.exe -p wmipersistence -i <|path|OBJECTS.DATA> -o <|output|wmipersistence.json>'
     - '<|parsingdir|>MasterParser.exe -p rua -i <|path|OBJECTS.DATA> -o <|output|wmirua.json>'

• description : a description about the artifact. This key is used in hoarder command line to show information about the artifact.

parsers directives:

• <|path|>: e.g. <|path|$MFT> will be replaced with the path where any $MFT file under the artifact path exists, and a command will be run for each $MFT file found. To direct it to a folder it must end with \. Example: <|path|\> or <|path|windows\>.
• <|output|>: will be replaced with a unique output path to ensure no file is overwritten. |output| can be followed by a suffix (not a path - not ending in \) to be appended to all auto-generated filenames. For example, <|output|evtx.json> and the suffix evtx.json will be added to all windows events parsing output files. Tip: it is recommended to always use <|output|> to avoid writing results outside the working directory or overwriting outputs.
• <|parsingdir|>: this will be replaced with the path of the parsing working directory, where all files in parsers.zip are extracted, (WITH the trailing \). This directive doesn't take a suffix but you can append right after it. For example, if your parser takes in a rules folder in parsers.zip, you can refer to it as <|parsingdir|>rules\. This directive needs to go before any use of a tool or supplied input in parsers.zip.

Parsing

Starting from hoarder 4.0.0, hoarder supports parsing collected artifacts. There are three major parts to parsing:

1. parsers.zip: contains all of your parser binaries, scripts, and data files. Hoarder binary release comes prepackaged with MasterParser. To add your own parsers, place a parsers.zip next to hoarder.exe containing all of your parsers used. If you are running from source create your own parsers.zip and rename or delete the default parsers.zip.
2. configuration: in Hoarder.yml, add your parser command (refer to Add an Artifact to Hoarder.yml)
3. command-line arguments: -pa to have hoarder bring both raw and parsed artifacts. -n to have hoarder bring only parsing results. Parsing arguments work with other switches as you would expect. Meaning, If a group or a single artifact is chosen, parsing will only be applied to the chosen artifacts.

Plugins and Commands:

• Plugins: predefined functions inside the script that can be called to get specific results, such as processes and services.
• Commands: defined inside Hoarder.yml to execute single built-in commands, such as systeminfo.

Command Execution

Hoarder also support the execution of system commands. The following example shows the execution of the command "systeminfo":

  SystemInfo:
    output: 'SystemInfo'
    cmd: 'systeminfo'
    description: 'Get system information'

• SystemInfo : This is the name of the artifact. This name will be used as an argument in the hoarder command line.

• output : This is the name of the output folder for this artifact.

• cmd : The command to be executed.

• description : a description about the artifact. This key is used in hoarder command line to show some information about the artifact.

Running and freezing from source

Environment

Make sure your environment or virtual environment is setup with Python 3.8.3

Installing Dependencies

To install all Hoarder dependencies, run the following command from an elevated terminal:

pip install -r requirements.txt

Freezing Hoarder into a binary

If you want to freeze your own binary make sure you install PyInstaller 3.6. You may need to change or add to this command if your changes contain hidden imports, data files, or dll dependencies that PyInstaller needs to know about. Here is the command for the current release:

 pyinstaller -F --add-binary ".\msvcp140.dll;." --add-binary ".\vcruntime140_1.dll;." --add-data ".\Hoarder.yml;." --add-data ".\parsers.zip;." -i .\hoarder.ico .\hoarder.py

Pull requests

Pull requests are welcome! They will be tested then applied. We'll try to do some simple modifications if testing is not successful depending on the amount of modifications needed.
