# MISP modules [![Build Status](https://travis-ci.org/MISP/misp-modules.svg?branch=master)](https://travis-ci.org/MISP/misp-modules) [![Coverage Status](https://coveralls.io/repos/github/MISP/misp-modules/badge.svg?branch=master)](https://coveralls.io/github/MISP/misp-modules?branch=master) [![codecov](https://codecov.io/gh/MISP/misp-modules/branch/master/graph/badge.svg)](https://codecov.io/gh/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. * [countrycode](misp_modules/modules/expansion/countrycode.py) - a hover module to tell you what country a URL belongs to. * [virustotal](misp_modules/modules/expansion/virustotal.py) - an expansion module to pull known resolutions and malware samples related with an IP/Domain from virusTotal (this modules require a VirusTotal private API key) ### Export modules * [CEF](misp_modules/modules/export_mod/cef_export.py) module to export Common Event Format (CEF). ### 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/import_mod/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.
