are in addition to MISP attributes to allow advanced combinations of attributes. The creation of these objects
and their associated attributes are based on real cyber security use-cases and existing practices in information sharing.
Feel free to propose your own MISP objects to be included in MISP. The system is similar to the [misp-taxonomies](https://github.com/MISP/misp-taxonomies) where anyone can contribute their own objects to be included in MISP without modifying software.
Each attribute must contain a reference **misp-attribute** to reference an existing attribute definition in MISP (MISP attributes types are case-sensitive).
* [objects/ail-leak](objects/ail-leak/definition.json) - information leak object as defined by the [AIL Analysis Information Leak framework](https://www.github.com/CIRCL/AIL-framework).
* [objects/android-permission](objects/android-permission/definition.json) - A set of android permissions - one or more permission(s) which can be linked to other objects (e.g. file).
* [objects/asn](objects/asn/definition.json) - Autonomous system object describing a BGP autonomous system which can include one or more network operators management an entity (e.g. ISP) along with their routing policy, routing prefixes or alike.
* [objects/bank-account](objects/bank-account/definition.json) - Object describing bank account information based on account description from goAML 4.0.
* [objects/course-of-action](objects/course-of-action/definition.json) - An object describing a Course of Action such as a specific measure taken to prevent or respond to an attack.
* [objects/credential](objects/credential/definition.json) - A credential object describes one or more credential(s) including password(s), api key(s) or decryption key(s).
* [objects/exploit-poc](objects/exploit-poc/definition.json) - Exploit-poc object describing a proof of concept or exploit of a vulnerability. This object has often a relationship with a vulnerability object.
* [objects/original-imported-file](objects/original-imported-file/definition.json) - Object to describe the original files used to import data in MISP.
* [objects/passive-dns](objects/passive-dns/definition.json) - Passive DNS records as expressed in [draft-dulaunoy-dnsop-passive-dns-cof-01](https://tools.ietf.org/html/draft-dulaunoy-dnsop-passive-dns-cof-01).
* [objects/paste](objects/paste/definition.json) - Object describing a paste or similar post from a website allowing to share privately or publicly posts.
* [objects/script](objects/script/definition.json) - Object describing a computer program written to be run in a special run-time environment. The script or shell script can be used for malicious activities but also as support tools for threat analysts.
* [objects/short-message-service](objects/short-message-service/definition.json) - Short Message Service (SMS) object template describing one or more SMS message(s).
* [objects/ss7-attack](objects/ss7-attack/definition.json) - SS7 object of an attack seen on a GSM, UMTS or LTE network via SS7 logging.
* [objects/stix2-pattern](objects/stix2-pattern/definition.json) - An object describing a STIX pattern. The object can be linked via a relationship to other attributes or objects to describe how it can be represented as a STIX pattern.
* [objects/target-system](objects/target-system/definition.json) - Description about an targeted system, this could potentially be a compromised internal system.
* [objects/timecode](objects/timecode/definition.json) - Timecode object to describe a start of video sequence (e.g. CCTV evidence) and the end of the video sequence.
* [objects/timestamp](objects/timestamp/definition.json) - A generic timestamp object to represent time including first time and last time seen. Relationship will then define the kind of time relationship.
* [objects/vulnerability](objects/vulnerability/definition.json) - Vulnerability object to describe software or hardware vulnerability as described in a CVE.
* [objects/url](objects/url/definition.json) - url object describes an url along with its normalized field (e.g. using faup parsing library) and its metadata.
* [objects/yara](objects/yara/definition.json) - YARA object describing a YARA rule along with the version supported and context (such as memory, network, disk).
The MISP object model is open and allows user to use their own relationships. MISP provides a list of default relationships that can be used if you plan to share your events with other MISP communities.
- [relationships](relationships/definition.json) - list of predefined default relationships which can be used to link MISP objects together and explain the context of the relationship.
Fork the project, create a new directory in the [objects directory](objects/) matching your object name. Objects must be composed
of existing MISP attributes. If you are missing a specific attributes, feel free to open an issue in the [MISP project](https://www.github.com/MISP/MISP).
The MISP objects are documented at the following location in [HTML](https://www.misp-project.org/objects.html) and [PDF](https://www.misp-project.org/objects.pdf).
The documentation is automatically generated from the MISP objects template expressed in JSON.
## What are the advantages of MISP objects versus existing standards?
MISP objects are dynamically used objects that are contributed by users of MISP (the threat sharing platform) or other information sharing platforms.
The aim is to allow a dynamic update of objects definition in operational distributed sharing systems like MISP. Security threats and their related indicators are quite dynamic, standardized formats are quite static and new indicators require a significant time before being standardized.
The MISP objects model allows to add new combined indicators format based on their usage without changing the underlying code base of MISP or other threat sharing platform using it. The definition of the objects can be then propagated along with the indicators itself.
