Manage threat collections

ExtraHop Reveal(x) includes curated threat collections that identify suspicious hostnames, domains, IP addresses, and URIs in charts and tables throughout the system. You must enable these threat collections before threat intelligence is applied to your network activity. In addition, you can upload threat collections from free or commercial sources as a custom threat collection, and you can import threat collections from partner integrations to Reveal(x) 360, such as CrowdStrike Falcon.

To add threat intelligence from CrowdStrike, see Integrate Reveal(x) 360 with CrowdStrike.

Here are some important considerations about threat collections:

  • ExtraHop currently supports STIX versions 1.0 - 1.2.
  • The maximum number of observables that a threat collection can contain depends on your platform and license. Contact your ExtraHop representative for more information.
  • You can directly upload threat collections to Reveal(x) 360 systems for self-managed sensors. Contact ExtraHop Support to upload a threat collection to ExtraHop-managed sensors.

Before you begin

Enable ExtraHop-curated threat collections

Enable an ExtraHop threat collection to observe activity and identify indicators of compromise throughout the system.

  1. Log in to the ExtraHop system through https://<extrahop-hostname-or-IP-address>.
  2. Click the System Settings icon and then click Threat Intelligence.
  3. In the ExtraHop Threat Intelligence table, select the Enabled checkbox in the Status column

Upload a threat collection

Upload threat collections from free and commercial sources to identify indicators of compromise throughout the ExtraHop system. Because threat intelligence data is updated frequently (sometimes daily), you might need to update a threat collection with the latest data. When you update a threat collection with new data, the collection is deleted and replaced, and not appended to an existing collection.

  • You can directly upload threat collections to Reveal(x) 360 systems for self-managed sensors. Contact ExtraHop Support to upload a threat collection to ExtraHop-managed sensors.
Tip:Upload STIX files through the REST API.

Custom threat collections must be formatted in Structured Threat Information eXpression (STIX) as TAR.GZ files. Reveal(x) currently supports STIX version 1.0 - 1.2.

  1. Log in to the ExtraHop system through https://<extrahop-hostname-or-IP-address>.
  2. Click the System Settings icon and then click Threat Intelligence.
  3. Click Manage custom collections.
  4. Click Upload New Collection.
  5. In the Collection ID field, type a unique collection ID. The ID can only contain alphanumeric characters and spaces are not allowed.
  6. Click Choose file and select a .tgz file that contains a STIX file.
  7. Type a display name in the Display Name field.
  8. Click Upload Collection.
