Enrich an `inet:fqdn` node

Enrich an inet:fqdn node with pwc.threatintel.enrich:

> [ inet:fqdn=root.anynucleus.com ] | pwc.threatintel.enrich
inet:fqdn=root.anynucleus.com
        .created = 2024/11/19 21:26:26.942
        .seen = ('2022/11/11 17:22:55.396', '2022/11/11 17:22:55.397')
        :domain = anynucleus.com
        :host = root
        :issuffix = false
        :iszone = false
        :zone = anynucleus.com

        #rep.pwc.red_dev_14
        #rep.pwc.tlp.amber

Ingest reports by time range

If Synapse-FileParser is installed on the Cortex, YARA rules for reports will also be downloaded and parsed to create it:app:yara:rule nodes. In the example below it is not available, and therefore a warning is produced.

Pull reports from the report feed using pwc.threatintel.report.feed:

> pwc.threatintel.report.feed --min-time 2022-11-10 --max-time 2022-11-15 --yield | limit 1
WARNING: Synapse-FileParser >=4.2.1,<5.0.0 is required for parsing YARA rules.

Ingest indicators by time range

Pull indicators from the ioc feed using pwc.threatintel.ioc.feed:

Use of `meta:source` nodes

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

> meta:source=be4af1ebfda6b73a7ce0099e27566daf
meta:source=be4af1ebfda6b73a7ce0099e27566daf
        .created = 2024/11/19 21:26:27.352
        :name = pwc threat intel api

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

> risk:threat +{ <(seen)- meta:source=be4af1ebfda6b73a7ce0099e27566daf }
risk:threat=c5793d05efe26d52ff5f3f819506a5db
        .created = 2024/11/19 21:26:35.100

        :reporter:name = pwc
