Search | Query Syntax | Entities | Observable relations#

You can search for Entities by defining which types of Observable they are related to or the relationship types they have to the Observables they are related to.

Entity-Observable relationship type#

Use link names to search for Entities that have a specific type of relationship to any Observables.

Let’s assume that an analyst is investigating a threat scenario where a threat actor exploits the CVE-2017-8793 vulnerability to gain access to the targeted victim’s assets.

The analyst may want to search EclecticIQ Intelligence Center for: Exploit target Entities with Domain observables that are related to the Exploit target Entity as vulnerability.

Example query:

data.type:exploit-target AND \
extracts.kind:domain AND \
meta.bundled_extracts.link_types:vulnerability OR \
extracts.instance_meta.link_types:vulnerability

In the search query example:

  • meta.bundled_extracts.link_types is the JSON path pointing to the JSON field in the Entity data structure that holds the link name value defining the relationship between Entities and the corresponding bundled Observables.

  • extracts.instance_meta.link_types is the JSON path pointing to the JSON field in the Entity data structure that holds the link name value defining the relationship between Entities and non-embedded Observables.

  • vulnerability is the link name value defining the the type of Entity-Observable relationship you are looking for.

If the link name value search string contains multiple words separated by spaces, wrap the search string in double quotes (example: "my multiple word search string").

The following table maps the link name values you can enter in a search query to the corresponding options displayed in the GUI (Campaign Entities have no link names to define relationships with Observables):
