Watchlist 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: v3

Introduction

The Watchlist API enables you to manage Watchlists for your organization throughout their lifecycle - creation, update and removal - as well as associated Reports and IOCs.

It allows you to manage both Watchlists subscribed from third party threat intelligence feeds (aka “classifier” watchlists) and those custom built for your organization’s specific needs from new and/or existing Reports (aka “report” watchlists).

With visibility across your fleet of monitored endpoints, you can identify processes that are acting abnormally and over time, focus your watchlists to generate hits and alerts only for unexpected or unwanted activity. This includes:

  • Creating new report Watchlists from scratch and add/remove/disable/enable new or existing Reports to that custom Watchlist
  • Configuring or disabling existing Watchlists including enabling “tagging” aka generating “hits” and/or “alerting” aka generating Watchlist Alerts
  • Configuring or deleting Reports and their included IOCs
  • Disabling (ignore) individual Reports and IOCs to stop generating tagged events aka hits in otherwise-tagging-enabled Watchlists

The information model for Carbon Black Cloud Watchlists is comprised of three units of information:

  • IOCs are the smallest unit of information - a single indicator of compromise, to be searched across your organization’s Enterprise EDR data
  • Reports collect one or more IOCs together as a unit of control - all collected IOCs can be enabled or disabled from generating hits and alerts in a single action
  • Watchlists collect one or more Reports together as another unit of control - all Reports in one Watchlist can be enabled or disabled for Alerting or reporting in your organization in a single action

Requirements

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

Update Watchlist

Update watchlist with watchlist_id. This will update the tags and alert status as well as any reports or classifiers attached to the watchlist. If a field is missing or null (e.g. tags_enabled is not included) that field will not be updated. Cannot update report watchlist with empty report_ids list.

Alerting is not supported on the following feeds due to the volume of hits:

  • ATT&CK Framework
  • Carbon Black Early Access Indicators
  • Carbon Black Endpoint Visibility
  • Carbon Black Suspicious Indicators

Attempting to enable an alert on any of these feeds will result in a 400 error.

Examples

IOCs

IOCs can be written in three different ways: equality, regex, or query. The equality and regex IOCs are run on ingress whereas the query IOC is run using a rolling window once the data reaches the data store. Because the equality and regex IOCs happen on ingress and do not need any part of the query language, these IOC match types perform better than the query IOC.

  • An equality IOC will hit when the field value is exactly equal to any of the values.
  • A regex IOC will hit if the field value matches on the regular expression provided in the values array.
  • A query IOC will hit if the query in the values array matches on a particular document. These IOCs are equivalent to running searches on the Investigate page. Query IOCs are useful when you need query language to determine if the process is important enough to generate a hit.

Which fields can be used in which types of IOCs? Consult the Platform Search Fields documentation for a list of all possible fields to use in Watchlists:

  • query IOCs can use any Platform Search field which is documented as Searchable
  • equality and regex IOCs can use any Platform Search field, except the Aggregation only fields i.e. num_devices, num_events
