Abstract

   This document describes the MISP galaxy format which describes a
   simple JSON format to represent galaxies and clusters that can be
   attached to MISP events or attributes.  A public directory of MISP
   galaxies is available and relies on the MISP galaxy format.  MISP
   galaxies are used to add further informations on a MISP event.MISP
   galaxy is a public repository [MISP-G] of known malware, threats
   actors and various other collections of data that can be used to
   mark, classify or label data in threat information sharing.

1.  Introduction

   Sharing threat information became a fundamental requirements on the
   Internet, security and intelligence community at large.  Threat
   information can include indicators of compromise, malicious file
   indicators, financial fraud indicators or even detailed information
   about a threat actor.  Some of these informations, such as malware or
   threat actors are common to several security events.  MISP galaxy is
   a public repository [MISP-G] of known malware, threats actors and
   various other collections of data that can be used to mark, classify
   or label data in threat information sharing.

   In the MISP galaxy context, clusters help analysts to give more
   informations about their cybersecurity events, indicators or threats.
   MISP galaxies can be used for classification, filtering, triggering
   actions or visualisation depending on their use in threat
   intelligence platforms such as MISP [MISP-P].
