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.X.

Existing MISP modules

• DNS - a simple module to resolve MISP attributes like hostname and domain to expand IP addresses attributes.

How to add your own MISP modules?

Create your module in modules/expansion/. The module should have at minimum two functions:

• introspection function that returns an array of the supported attributes by your expansion module.
• handler function which accepts a JSON document to expand the values and return a dictionary of the expanded values.

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": "dns",
    "mispattributes": [
      "hostname",
      "domain"
    ]
  }
]

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:

{"module": "dns", "hostname": "www.github.com"}

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
