# MISP modules
6 years ago
[![Build Status](https://travis-ci.org/MISP/misp-modules.svg?branch=master)](https://travis-ci.org/MISP/misp-modules)
MISP modules are autonomous modules that can be used for expansion and other services in [MISP](https://github.com/MISP/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](https://www.circl.lu/assets/files/misp-training/3.1-MISP-modules.pdf) slides from MISP training.
## Existing MISP modules
### Expansion modules
* [ASN History](misp_modules/modules/expansion/asn_history.py) - a hover and expansion module to expand an AS number with the ASN description and its history.
* [CIRCL Passive SSL](misp_modules/modules/expansion/circl_passivessl.py) - a hover and expansion module to expand IP addresses with the X.509 certificate seen.
* [CIRCL Passive DNS](misp_modules/modules/expansion/circl_passivedns.py) - a hover and expansion module to expand hostname and IP addresses with passive DNS information.
* [CVE](misp_modules/modules/expansion/cve.py) - a hover module to give more information about a vulnerability (CVE).
* [DNS](misp_modules/modules/expansion/dns.py) - a simple module to resolve MISP attributes like hostname and domain to expand IP addresses attributes.
* [EUPI](misp_modules/modules/expansion/eupi.py) - a hover and expansion module to get information about an URL from the [Phishing Initiative project](https://phishing-initiative.eu/?lang=en).
* [IPASN](misp_modules/modules/expansion/ipasn.py) - a hover and expansion to get the BGP ASN of an IP address.
* [passivetotal](misp_modules/modules/expansion/passivetotal.py) - a [passivetotal](https://www.passivetotal.org/) module that queries a number of different PassiveTotal datasets.
* [sourcecache](misp_modules/modules/expansion/sourcecache.py) - a module to cache a specific link from a MISP instance.
### Import modules
* [OCR](misp_modules/modules/import_mod/ocr.py) Optical Character Recognition (OCR) module for MISP to import attributes from images, scan or faxes.
* [stiximport](misp_modules/modules/expansion/stiximport.py) - An import module to process STIX xml/json
## How to install and start MISP modules?
~~~~bash
sudo apt-get install python3-dev python3-pip libpq5
cd /usr/local/src/
sudo git clone https://github.com/MISP/misp-modules.git
cd misp-modules
sudo pip3 install --upgrade -r REQUIREMENTS
sudo pip3 install --upgrade .
sudo vi /etc/rc.local, add this line: `sudo -u www-data misp-modules -s`
~~~~
## How to add your own MISP modules?
Create your module in [misp_modules/modules/expansion/](misp_modules/modules/expansion/). 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.
If your module requires additional configuration (to be exposed via the MISP user-interface), 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"
],
...
~~~
### Module type
A MISP module can be of two 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.
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:
~~~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:
~~~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):
~~~json
{
"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.
## 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.
