    <p>Hi!<br>
<p>MISP modules are autonomous modules that can be used for expansion and other services in <a href="https://github.com/MISP/MISP">MISP</a>.</p>
<p>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.</p>
<p>MISP modules support is included in MISP starting from version 2.4.28.</p>
<p>For more information: <a href="https://www.circl.lu/assets/files/misp-training/3.1-MISP-modules.pdf">Extending MISP with Python modules</a> slides from MISP training.</p>
