Feed Search API for Enterprise EDR

Carbon Black Cloud Enterprise EDR (Endpoint Detection and Response) is the new name for the product formerly called CB ThreatHunter.

Version: v1

Introduction

The Feed Search API enables you to search across all reports available to your organization, both those published by Carbon Black Cloud in threat intelligence feeds as well as all custom reports generated within your organization.

This allows you to create custom watchlists that can hit and/or alert on a targeted set of events across your organization’s fleet.

Requirements

  • Enterprise EDR product
  • All API calls require an API key with appropriate permissions

Authentication

Determine whether you use Carbon Black Cloud or VMware Cloud Services Platform to manage identity and authorization, or see the Carbon Black Cloud API Access Guide for complete instructions.


Carbon Black Cloud Managed Identity and Authentication
Customize your access to the Carbon Black Cloud APIs with Role-Based Access Control; All APIs and Services authenticate via API Keys. To access the data in Carbon Black Cloud via API, you must set up a key with the correct permissions for the calls you want to make and pass it in the HTTP Headers.

Environment
Available on majority of environments; Use the Carbon Black Cloud Console URL, as described here.

API Route
Replace the {cbc-hostname} and {org_key} with the URL of your Environment and the org_key for your specific Org.
  • Search Feeds: {cbc-hostname}/threathunter/feedsearch/v1/orgs/{org_key}/search
  • Search Feeds: {cbc-hostname}/threathunter/feedsearch/v1/orgs/{org_key}/reports/_search
  • Suggest Fields: {cbc-hostname}/threathunter/feedsearch/v1/orgs/{org_key}/suggest

Access Level
Before you create your API Key, you need to create a "Custom" Access Level including each category:
  • org.feeds, allow permission to READ
  • org.watchlists, allow permission to READ

API Key
When creating your API Key, use the Access Level Type of "Custom" and select the Access Level you created. Details on constructing and passing the API Key in your requests are available here.

API Calls

Search across all feed and watchlist reports.

API Permissions Required

Identity Manager Permission (.notation name) Operation(s) Environment
Carbon Black Cloud org.feeds, org.watchlists READ Majority of environments

Request

GET {cbc-hostname}/threathunter/feedsearch/v1/orgs/{org_key}/search
