DigitalShadows2TH: Digital Shadows Alert Feeder for TheHive

Digital Shadows is a commercial Threat Intelligence provider which, according to their website:

monitors, manages and remediates digital risk across the widest range of data sources within the open, deep, and dark web to protect an organization’s business, brand, and reputation using several criteria, data analytics and human actions, their SearchLight service can notify customers about incidents and intel-incidents.

The service offers an API which can be leveraged to consume these two types of information and programmatically send them as alerts to TheHive, a popular free and open source Security Incident Response Platform designed to make life easier for SOCs, CSIRTs, CERTs and any information security practitioner dealing with security incidents that need to be investigated and acted upon swiftly.

DigitalShadows2TH is a free, open source Digital Shadows alert feeder for TheHive. You can use it to import Digital Shadows incidents and intel-incidents as alerts in TheHive, where they can be previewed and transformed into new cases using pre-defined incident response templates or added into existing ones.

DigitalShadows2TH is written in Python 3 by TheHive Project.

Overview

DigitalShadows2TH is made of several parts:

Prerequisites

You'll need Python 3.5s+, python-magic and requests libraries and TheHive4py, a Python client for TheHive.

Clone the repository then copy the config/config.py.template file as config/config.py and fill in the blanks: proxies if applicable, API keys, URLs, accounts pertaining to your Digital Shadows subscription and your instance of TheHive.

Note: you need TheHive 2.13 or later and an account with the ability to create alerts.

Then install the Python requirements:

$ pip3 install -r requirements.txt

The feeder can also be run using docker. Please refer to this section for more details.

Configure the feeder

inside the config folder, copy the config.py.sample to config.py and fill the blanks.

DigitalShadows = {
    'proxies':{
        'http': '',
        'https': ''
    },
    'url':'',
    'ds_key':'',
    'ds_secret':'',
    'verify':True,
    'fulltext':'true'
    'log_file':'log/ds2th.log',
    'monitoring_file':'log/ds2th.status'
}

TheHive = {
  'proxies':{
      'http': '',
      'https': ''
  },
    'url':'',
    'key':'',
    'template': {
        'default':''
    }
}

Several TheHive case templates can be defined, depending on DigitalShadows incident type. From the DigitalShadows API documentation, incidents can be any type of : 

DATA_LEAKAGE
CYBER_THREAT
PHYSICAL_SECURITY
SOCIAL_MEDIA_COMPLIANCE
BRAND_PROTECTION
INFRASTRUCTURE

To configure a custom case template for a type of incident, just update the configuration for TheHive like this :

  'templates': {
        'default':'DefaultCaseTemplateForDigitalShadows',
        'DATA_LEAKAGE': 'TheHiveCaseTemplateForDataLeaks'
    }

Usage

Once your configuration file config.py is ready and set up in the config folder, use the main program to fetch or find Digital Shadows (DS) incidents and intel-incidents:

./ds2th.py -h
usage: ds2th.py [-h] [-d] {inc,find} ...

Get DS alerts and create alerts in TheHive

positional arguments:
  {inc,find}   subcommand help
    inc        fetch incidents or intel-incidents by ID
    find       find incidents and intel-incidents in time

optional arguments:
  -h, --help   show this help message and exit
  -d, --debug  generate a log file and and active debug logging

The program comes with 2 commands:

If you need debbuging information, add the dswitch and the program will create a file called ds2th.log. It will be created in the log folder by default. This can be set up in the config/config.py configuration file.

Retrieve incidents or intel-incidents specified by their ID

./ds2th.py inc -h
usage: ds2th.py inc [-h] [-i ID [ID ...]] [-I ID [ID ...]]

optional arguments:
  -h, --help            show this help message and exit
  -i ID [ID ...], --incidents ID [ID ...]
                        Get DS incidents by ID
  -I ID [ID ...], --intel-incidents ID [ID ...]
                        Get DS intel-incidents by ID

Retrieve incidents and intel-incidents published during the last M minutes

./ds2th.py find -h
usage: ds2th.py find [-h] -l M [-m] [-i] [-I]

optional arguments:
  -h, --help      show this help message and exit
  -l M, --last M  Get all incidents published during the last [M] minutes
  -m, --monitor   active monitoring
  -i              Get Digital Shadows incidents only
  -I              Get Digital Shadows intel-incidents only

Use Cases

$ ./ds2th.py inc -i 123456
$ ./ds2th.py inc -I 123456
$ ./ds2th.py inc -I 123456 -i 234567
*/10    *   *   *   * /path/to/ds2th.py find -l 15
*/10    *   *   *   * /path/to/ds2th.py -d find -l 15

This will create a ds2th.log file in the log folder of the main program.

Monitoring

*/10    *   *   *   * /path/to/ds2th.py find -l 15 -m

The monitoring switch makes the program "touch" a file named ds2th.status once it has successfully finished. This file is set by default in the logfolder. To monitor it, just check the modification date of this file and compare it to the frequency used in your crontab entry.

Docker

The program can be run using Docker. You can pull the docker or build your own.

Pull the container

docker pull thehiveproject/ds2th:latest

Or build the container

If you want to build you own docker, in the project folder run the following command:

docker build --no-cache  -t thehiveproject/ds2th .

Prepare your environment and configure the feeder

Choose the folder where the configuration and logs will reside. (/opt/TheHive_feeders/Digitalshadows/ in our documentation)

DS2TH_HOMEDIR = /opt/TheHive_feeders/Digitalshadows/
mkdir -p $DS2TH_HOMEDIR/{config,log}
wget -O $DS2TH_HOMEDIR/config/__init__.py https://raw.githubusercontent.com/TheHive-Project/DigitalShadows2TH/master/config/__init__.py
wget -O $DS2TH_HOMEDIR/config/config.py https://raw.githubusercontent.com/TheHive-Project/DigitalShadows2TH/master/config.py.template

and edit $DS2TH_HOMEDIR/config/config.py following instructions in #configure-the-feeder.

Run with docker

docker  run \
--rm\
--net=host \
--mount type=bind,source="$DS2TH_HOMEDIR"/config,target=/app/config \
--mount type=bind,source="$DS2TH_HOMEDIR"/log,target=/app/log \
thehiveproject/ds2th OPTIONS

Run it with cron

For example: 

*/10    *   *   *   * docker run --rm --net=host --mount type=bind,source="$DS2TH_HOMEDIR"/config,target=/app/config --mount type=bind,source="$DS2TH_HOMEDIR"/log,target=/app/log thehiveproject/ds2th -d find -l 15 -m
