MISP modules

MISP modules are autonomous modules that can be used for expansion and other services in MISP.

The modules are written in Python 3 following a simple API interface. The objective is to ease the extensions of MISP functionalities without modifying core components. The API is available via a simple REST API which is independent from MISP installation or configuration.

MISP modules support is included in MISP starting from version 2.4.28.

For more information: Extending MISP with Python modules slides from MISP training.

How to install and start MISP modules in a Python virtualenv? (recommended)

sudo apt-get install python3-dev python3-pip libpq5 libjpeg-dev tesseract-ocr libpoppler-cpp-dev imagemagick virtualenv libopencv-dev zbar-tools libzbar0 libzbar-dev libfuzzy-dev -y
sudo -u www-data virtualenv -p python3 /var/www/MISP/venv
cd /usr/local/src/
sudo git clone https://github.com/MISP/misp-modules.git
cd misp-modules
sudo -u www-data /var/www/MISP/venv/bin/pip install -I -r REQUIREMENTS
sudo -u www-data /var/www/MISP/venv/bin/pip install .
# Start misp-modules as a service
sudo cp etc/systemd/system/misp-modules.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now misp-modules
/var/www/MISP/venv/bin/misp-modules -l 127.0.0.1 -s & #to start the modules

How to install and start MISP modules on RHEL-based distributions ?

As of this writing, the official RHEL repositories only contain Ruby 2.0.0 and Ruby 2.1 or higher is required. As such, this guide installs Ruby 2.2 from the SCL repository.

sudo yum install rh-ruby22
sudo yum install openjpeg-devel
sudo yum install rubygem-rouge rubygem-asciidoctor zbar-devel opencv-devel gcc-c++ pkgconfig poppler-cpp-devel python-devel redhat-rpm-config
cd /var/www/MISP
git clone https://github.com/MISP/misp-modules.git
cd misp-modules
sudo -u apache /usr/bin/scl enable rh-python36 "virtualenv -p python3 /var/www/MISP/venv"
sudo -u apache /var/www/MISP/venv/bin/pip install -U -I -r REQUIREMENTS
sudo -u apache /var/www/MISP/venv/bin/pip install -U .

Create the service file /etc/systemd/system/misp-modules.service :

echo "[Unit]
Description=MISP's modules
After=misp-workers.service

[Service]
Type=simple
User=apache
Group=apache
ExecStart=/usr/bin/scl enable rh-python36 rh-ruby22  '/var/www/MISP/venv/bin/misp-modules –l 127.0.0.1 –s'
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target" | sudo tee /etc/systemd/system/misp-modules.service

The After=misp-workers.service must be changed or removed if you have not created a misp-workers service. Then, enable the misp-modules service and start it:

systemctl daemon-reload
systemctl enable --now misp-modules

How to add your own MISP modules?

Create your module in misp_modules/modules/expansion/, misp_modules/modules/export_mod/, or misp_modules/modules/import_mod/. The module should have at minimum three functions:

introspection function that returns a dict of the supported attributes (input and output) by your expansion module.
handler function which accepts a JSON document to expand the values and return a dictionary of the expanded values.
version function that returns a dict with the version and the associated meta-data including potential configurations required of the module.

Don't forget to return an error key and value if an error is raised to propagate it to the MISP user-interface.

Your module's script name should also be added in the __all__ list of <module type folder>/__init__.py in order for it to be loaded.

...
    # Checking for required value
    if not request.get('ip-src'):
        # Return an error message
        return {'error': "A source IP is required"}
...

introspection

The function that returns a dict of the supported attributes (input and output) by your expansion module.

mispattributes = {'input': ['link', 'url'],
                  'output': ['attachment', 'malware-sample']}

def introspection():
    return mispattributes

version

The function that returns a dict with the version and the associated meta-data including potential configurations required of the module.

Additional Configuration Values

If your module requires additional configuration (to be exposed via the MISP user-interface), you can define those in the moduleconfig value returned by the version function.

# config fields that your code expects from the site admin
moduleconfig = ["apikey", "event_limit"]

def version():
    moduleinfo['config'] = moduleconfig
    return moduleinfo

When you do this a config array is added to the meta-data output containing all the potential configuration values:

"meta": {
      "description": "PassiveTotal expansion service to expand values with multiple Passive DNS sources",
      "config": [
        "username",
        "password"
      ],
      "module-type": [
        "expansion",
        "hover"
      ],

...

If you want to use the configuration values set in the web interface they are stored in the key config in the JSON object passed to the handler.

def handler(q=False):

    # Check if we were given a configuration
    config = q.get("config", {})

    # Find out if there is a username field
    username = config.get("username", None)

handler

The function which accepts a JSON document to expand the values and return a dictionary of the expanded values.

def handler(q=False):
    "Fully functional rot-13 encoder"
    if q is False:
        return False
    request = json.loads(q)
    src = request.get('ip-src')
    if src is None:
        # Return an error message
        return {'error': "A source IP is required"}
    else:
        return {'results':
                codecs.encode(src, "rot-13")}

export module

For an export module, the request["data"] object corresponds to a list of events (dictionaries) to handle.

Iterating over events attributes is performed using their Attribute key.

...
for event in request["data"]:
        for attribute in event["Attribute"]:
          # do stuff w/ attribute['type'], attribute['value'], ...
...

### Returning Binary Data

If you want to return a file or other data you need to add a data attribute.

~~~python
{"results": {"values": "filename.txt",
             "types": "attachment",
             "data"  : base64.b64encode(<ByteIO>)  # base64 encode your data first
             "comment": "This is an attachment"}}

If the binary file is malware you can use 'malware-sample' as the type. If you do this the malware sample will be automatically zipped and password protected ('infected') after being uploaded.

{"results": {"values": "filename.txt",
             "types": "malware-sample",
             "data"  : base64.b64encode(<ByteIO>)  # base64 encode your data first
             "comment": "This is an attachment"}}

To learn more about how data attributes are processed you can read the processing code here.

Module type

A MISP module can be of four types:

expansion - service related to an attribute that can be used to extend and update an existing event.
hover - service related to an attribute to provide additional information to the users without updating the event.
import - service related to importing and parsing an external object that can be used to extend an existing event.
export - service related to exporting an object, event, or data.

module-type is an array where the list of supported types can be added.

Testing your modules?

MISP uses the modules function to discover the available MISP modules and their supported MISP attributes:

% curl -s http://127.0.0.1:6666/modules | jq .
[
  {
    "name": "passivetotal",
    "type": "expansion",
    "mispattributes": {
      "input": [
        "hostname",
        "domain",
        "ip-src",
        "ip-dst"
      ],
      "output": [
        "ip-src",
        "ip-dst",
        "hostname",
        "domain"
      ]
    },
    "meta": {
      "description": "PassiveTotal expansion service to expand values with multiple Passive DNS sources",
      "config": [
        "username",
        "password"
      ],
      "author": "Alexandre Dulaunoy",
      "version": "0.1"
    }
  },
  {
    "name": "sourcecache",
    "type": "expansion",
    "mispattributes": {
      "input": [
        "link"
      ],
      "output": [
        "link"
      ]
    },
    "meta": {
      "description": "Module to cache web pages of analysis reports, OSINT sources. The module returns a link of the cached page.",
      "author": "Alexandre Dulaunoy",
      "version": "0.1"
    }
  },
  {
    "name": "dns",
    "type": "expansion",
    "mispattributes": {
      "input": [
        "hostname",
        "domain"
      ],
      "output": [
        "ip-src",
        "ip-dst"
      ]
    },
    "meta": {
      "description": "Simple DNS expansion service to resolve IP address from MISP attributes",
      "author": "Alexandre Dulaunoy",
      "version": "0.1"
    }
  }
]

The MISP module service returns the available modules in a JSON array containing each module name along with their supported input attributes.

Based on this information, a query can be built in a JSON format and saved as body.json:

{
  "hostname": "www.foo.be",
  "module": "dns"
}

Then you can POST this JSON format query towards the MISP object server:

curl -s http://127.0.0.1:6666/query -H "Content-Type: application/json" --data @body.json -X POST

The module should output the following JSON:

{
  "results": [
    {
      "types": [
        "ip-src",
        "ip-dst"
      ],
      "values": [
        "188.65.217.78"
      ]
    }
  ]
}

It is also possible to restrict the category options of the resolved attributes by passing a list of categories along (optional):

{
  "results": [
    {
      "types": [
        "ip-src",
        "ip-dst"
      ],
      "values": [
        "188.65.217.78"
      ],
      "categories": [
        "Network activity",
        "Payload delivery"
      ]
    }
  ]
}

For both the type and the category lists, the first item in the list will be the default setting on the interface.

Enable your module in the web interface

For a module to be activated in the MISP web interface it must be enabled in the "Plugin Settings.

Go to "Administration > Server Settings" in the top menu

Go to "Plugin Settings" in the top "tab menu bar"
Click on the name of the type of module you have created to expand the list of plugins to show your module.
Find the name of your plugin's "enabled" value in the Setting Column. "Plugin.[MODULE NAME]_enabled"
Double click on its "Value" column

Priority        Setting                         Value   Description                             Error Message
Recommended     Plugin.Import_ocr_enabled       false   Enable or disable the ocr module.       Value not set.

Use the drop-down to set the enabled value to 'true'

Priority        Setting                         Value   Description                             Error Message
Recommended     Plugin.Import_ocr_enabled       true   Enable or disable the ocr module.       Value not set.

Set any other required settings for your module

In this same menu set any other plugin settings that are required for testing.

Install misp-module on an offline instance.

First, you need to grab all necessary packages for example like this :

Use pip wheel to create an archive

mkdir misp-modules-offline
pip3 wheel -r REQUIREMENTS shodan --wheel-dir=./misp-modules-offline
tar -cjvf misp-module-bundeled.tar.bz2 ./misp-modules-offline/*

On offline machine :

mkdir misp-modules-bundle
tar xvf misp-module-bundeled.tar.bz2 -C misp-modules-bundle
cd misp-modules-bundle
ls -1|while read line; do sudo pip3 install --force-reinstall --ignore-installed --upgrade --no-index --no-deps ${line};done

Next you can follow standard install procedure.

How to contribute your own module?

Fork the project, add your module, test it and make a pull-request. Modules can be also private as you can add a module in your own MISP installation.

Tips for developers creating modules

Download a pre-built virtual image from the MISP training materials.

Create a Host-Only adapter in VirtualBox
Set your Misp OVA to that Host-Only adapter
Start the virtual machine
Get the IP address of the virtual machine
SSH into the machine (Login info on training page)
Go into the misp-modules directory

cd /usr/local/src/misp-modules

Set the git repo to your fork and checkout your development branch. If you SSH'ed in as the misp user you will have to use sudo.

sudo git remote set-url origin https://github.com/YourRepo/misp-modules.git
sudo git pull
sudo git checkout MyModBranch

Remove the contents of the build directory and re-install misp-modules.

sudo rm -fr build/*
sudo -u www-data /var/www/MISP/venv/bin/pip install --upgrade .

SSH in with a different terminal and run misp-modules with debugging enabled.

# In case misp-modules is not a service do:
# sudo killall misp-modules
sudo systemctl disable --now misp-modules
sudo -u www-data /var/www/MISP/venv/bin/misp-modules -d

In your original terminal you can now run your tests manually and see any errors that arrive

cd tests/
curl -s http://127.0.0.1:6666/query -H "Content-Type: application/json" --data @MY_TEST_FILE.json -X POST
cd ../
