Maltego OpenCTI Transforms

Use the OpenCTI platform in your Maltego application thanks to a set of transforms allowing you to explore the OpenCTI v6 data.

Installation

$ git clone https://github.com/MaltegoTech/opencti-maltego.git
$ cd opencti-maltego

Requirements

Please install the following requirements before generating the Maltego transforms:

Warning: you have to import Maltego STIX2 entities before installing these transforms.

$ pip3 install -r requirements.txt

This repository provides integration between OpenCTI and Maltego using the Maltego TRX library.

OpenCTI versions

Even if some compatibility exists, each OpenCTI version should be queried with the corresponding pycti version. The Python requirements need to be adapted accordingly.

This repository tries to remain compatible with the latest version of OpenCTI. You can use the tags to run an older version of this integration against an older version of OpenCTI. Some features and bugs are solved in both projects regularly, so these older versions may not work entirely.

Please try pinning the pycti version to the respective OpenCTI version.

Please open an issue for any compatibility problem you may have.

Installation

The local OpenCTI transforms leverage the Maltego TRX library. The first step is to create the configuration file:

$ cp config.py.sample config.py

Update the file according to your setup and then execute:

Setting Up the Environment

To ensure a smooth setup and to overcome environment issues, you can use the provided build_transforms.sh script. This script will create and activate a virtual environment, set the PYTHONPATH, install dependencies, and run the CLI.

Using build_transforms.sh

  1. Make the script executable:

    $ chmod +x build_transforms.sh

  2. Run the script from the root directory of the repository:

    $ ./build_transforms.sh

The build_transforms.sh script includes the following steps:

#!/bin/bash 
# build_transforms.sh

# Create and activate the virtual environment
python3 -m venv venv
source venv/bin/activate

# Set PYTHONPATH
export PYTHONPATH=$(pwd):$PYTHONPATH

# Install dependencies
python3 -m pip install -r trx/gunicorn/requirements.txt

# Run the CLI
python3 cli.py

# Deactivate the virtual environment
deactivate

Importing Transforms

If you use an iTDS, make sure to configure its URL in ./config.py, generate specific configuration files by running:

Import the following files in your iTDS management platform:

Output Files

After running the script, the following files will be generated in the output directory:

Import Local Transforms

To import the local transforms into Maltego, follow these steps:

Import the file output/local.mtz in Maltego using the "Import config" menu.

Importing Transforms into iTDS

To import the transforms into iTDS, follow these steps:

  1. Import the file output/config.mtz in iTDS using the "Import config" menu.
  2. Import the file output/settings.csv in iTDS using the "Import settings" menu.
  3. Import the files output/transforms_1-6.csv to output/transforms_6-6.csv in iTDS using the "Import transforms" menu.

Make sure to configure the iTDS URL in the config.py file as shown below:

HOST_URL = os.environ.get("HOST_URL", "https://localhost:8088")

opencti_url_setting = TransformSetting('opencti_url', 'OpenCTI URL', setting_type='string', default_value="", popup=True)
opencti_token_setting = TransformSetting('opencti_token', 'OpenCTI Token', setting_type='string', default_value="", popup=True)
ssl_verify_setting = TransformSetting('opencti_ssl_verify', 'SSL Verify', setting_type='boolean', default_value="false", popup=False)
http_proxies_setting = TransformSetting('opencti_http_proxies', 'HTTP Proxies', setting_type='string', optional=True, popup=False)

global_settings = [
    opencti_url_setting,
    opencti_token_setting,
    ssl_verify_setting,
    http_proxies_setting
]

global_registry = TransformRegistry(
    owner='Maltego Technologies GmbH - OpenCTI On-Premise',
    author='Maltego Technologies GmbH - OpenCTI On-Premise',
    host_url=HOST_URL,
    seed_ids=['opencti'],
    global_settings=global_settings
)

Running the Transform Server

The transform server can be run with or without SSL support. By default, it runs without SSL.

Without SSL

python project.py runserver --port 8080

With SSL

To run the server with SSL, make sure you have your cert.pem and key.pem files in the trx/gunicorn directory, the folder contains a sample certificate and key file. Then run the following command:

python project.py runserver --port 8080 --ssl
