Synapse-HYAS User Guide

Synapse-HYAS adds new Storm commands to allow you to query the HYAS API using your existing API key.

Getting Started

Check with your Admin to enable permissions and find out if you need a personal API key.

Examples

Setting your personal API key

To set-up a personal use API key:

> hyas.config.add myconfig myapikey --scope self
Synapse-HYAS config "myconfig" added

To use a configuration other than your default, pass --config <name> to the Synapse-HYAS commands.

Ingest passive DNS data for an FQDN

Enrich some nodes with hyas.enrich and yield the results:

> [ inet:fqdn=vertex.link ] | hyas.dns.passive --yield
inet:dns:a=('synapse.docs.vertex.link', '188.114.98.229')
        .created = 2026/11/05 22:40:46.268
        .seen = ('2024/01/18 00:00:00.000', '2024/01/18 00:00:00.001')
        :fqdn = synapse.docs.vertex.link
        :ipv4 = 188.114.98.229
inet:dns:a=('synapse.docs.vertex.link', '188.114.99.229')
        .created = 2026/11/05 22:40:46.276
        .seen = ('2024/01/18 00:00:00.000', '2024/01/18 00:00:00.001')
        :fqdn = synapse.docs.vertex.link
        :ipv4 = 188.114.99.229
inet:dns:a=('opticexample.aws.vertex.link', '34.238.200.34')
        .created = 2026/11/05 22:40:46.284
        .seen = ('2024/01/18 00:00:00.000', '2024/01/18 00:00:00.001')
        :fqdn = opticexample.aws.vertex.link
        :ipv4 = 34.238.200.34
inet:dns:a=('opticexample.aws.vertex.link', '3.217.213.111')
        .created = 2026/11/05 22:40:46.292
        .seen = ('2024/01/18 00:00:00.000', '2024/01/18 00:00:00.001')
        :fqdn = opticexample.aws.vertex.link
        :ipv4 = 3.217.213.111
inet:dns:a=('_.demo03.optic.vertex.link', '167.99.21.119')
        .created = 2026/11/05 22:40:46.298
        .seen = ('2024/01/16 00:00:00.000', '2024/01/16 00:00:00.001')
        :fqdn = _.demo03.optic.vertex.link
        :ipv4 = 167.99.21.119
inet:dns:a=('vertex.link', '137.184.16.9')
        .created = 2026/11/05 22:40:46.306
        .seen = ('2021/10/15 22:51:42.000', '2023/07/27 14:12:15.000')
        :fqdn = vertex.link
        :ipv4 = 137.184.16.9

Use of `meta:source` nodes

Synapse-HYAS uses a meta:source node and -(seen)> light weight edges to track nodes observed from the HYAS API.

> meta:source=7f0be4d00150f471348b7be1a413322b
meta:source=7f0be4d00150f471348b7be1a413322b
        .created = 2026/11/05 22:40:46.260
        :name = hyas api

Storm can be used to filter nodes to include/exclude nodes which have been observed by Synapse-HYAS. The following example shows how to filter the results of a query to include only results observed by Synapse-HYAS:

> inet:asn:name^=cloudflare -> inet:ipv4 +{ <(seen)- meta:source=7f0be4d00150f471348b7be1a413322b }
inet:ipv4=188.114.99.229
        .created = 2026/11/05 22:40:46.276
        :asn = 13335
        :latlong = 37.7621,-122.3971
        :type = unicast
inet:ipv4=188.114.98.229
        .created = 2026/11/05 22:40:46.268
        :asn = 13335
        :latlong = 37.7621,-122.3971
        :type = unicast
