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/switch2016/2-misp-modules.pdf) slides from MISP training.

|
## How to install and start MISP modules?
|
|
|
|
~~~~bash
|
|
sudo apt-get install python3-dev python3-pip libpq5 libjpeg-dev
|
|
cd /usr/local/src/
|
|
sudo git clone https://github.com/MISP/misp-modules.git
|
|
cd misp-modules
|
|
sudo pip3 install -I -r REQUIREMENTS
|
|
sudo pip3 install -I .
|
|
sudo vi /etc/rc.local, add this line: `sudo -u www-data misp-modules -s &`
|
|
misp-modules #to start the modules
|
|
~~~~
|
|
|
|
## How to add your own MISP modules?
|
|
|
|
Create your module in [misp_modules/modules/expansion/](misp_modules/modules/expansion/), [misp_modules/modules/export_mod/](misp_modules/modules/export_mod/), or [misp_modules/modules/import_mod/](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.
|
|
|
|
~~~python
|
|
...
|
|
# 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.
|
|
|
|
~~~python
|
|
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.
|
|
|
|
~~~python
|
|
# 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.
|
|
|
|
~~~python
|
|
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")}
|
|
~~~
|
|
|
|
### 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.
|
|
|
|
|
|
~~~python
|
|
{"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.](https://github.com/MISP/PyMISP/blob/4f230c9299ad9d2d1c851148c629b61a94f3f117/pymisp/mispevent.py#L185-L200)
|
|
|
|
|
|
### 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 .

|
|

|
|
"mispattributes": {
|

|
|
}
|
|
}
|
|
]
|
|
|
|
~~~
|
|
|
|
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:
|
|
|
|
~~~bash
|
|
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.
|
|
|
|
### 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 necessery 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](https://www.circl.lu/services/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 virutal machine
|
|
- SSH into the machine (Login info on training page)
|
|
- Go into the misp-modules directory
|
|
|
|
~~~bash
|
|
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.
|
|
|
|
~~~bash
|
|
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.
|
|
|
|
~~~python
|
|
sudo rm -fr build/*
|
|
sudo pip3 install --upgrade .
|
|
~~~
|
|
|
|
SSH in with a different terminal and run `misp-modules` with debugging enabled.
|
|
|
|
~~~python
|
|
sudo killall misp-modules
|
|
misp-modules -d
|
|
~~~
|
|
|
|
|
|
In your original terminal you can now run your tests manually and see any errors that arrive
|
|
|
|
~~~bash
|
|
cd tests/
|
|
curl -s http://127.0.0.1:6666/query -H "Content-Type: application/json" --data @MY_TEST_FILE.json -X POST
|
|
cd ../
|
|
~~~
|
