Feed Manager 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: v2

Introduction

The Feed Manager API enables you to manage third-party threat intelligence Watchlists (here called “Feeds”), including the ability to convert Carbon Black EDR queries for use in Carbon Black Cloud Enterprise EDR.

What is a Feed?

On the Carbon Black Cloud, a Feed is a collection of actionable threat intelligence, organized into Reports which are collections of one or more Indicators of Compromise (IOCs).

Feeds can be published to all organizations in an environment (public) or to a selection of managed organizations in an environment (reserved). It is also possible to publish a Feed to only one organization (private), but in practice this is unnecessary overhead for most organizations:

Public Feeds can only be created or edited by VMware Carbon Black; more information about the current public Feeds can be found on the Carbon Black User Community here.
Reserved Feeds can be created in another organization only by MSSPs.
Private Feeds can be created in anyone with sufficient privileges in the target organization.

In the Carbon Black Cloud console, Feeds are those Watchlists whose Type is “F” (Feed Subscription).

What is a Watchlist?

On the Carbon Black Cloud, a Watchlist is a specific set of subscribed Reports and their IOCs that are evaluated against incoming sensor data to enrich your search results with “hits” where the Watchlists found a match in your endpoint fleet’s events data.

Watchlists can be subscribed from a Feed, or can be created directly from a selection of existing Reports. Once created, a Watchlist can be edited in one of three ways:

New Reports can be added
Existing Reports in that Watchlist can be disabled or enabled
The Watchlist as a whole can be unsubscribed or disabled

What are the functional differences between Feeds and Watchlists?

Watchlists generate Hits and Alerts in your organization; Feeds do not
Watchlists are specific to one organization; Feeds can be published to one, some or all organizations
Watchlists can be unsubscribed; Feeds cannot be/do not need to be unsubscribed

Feeds are in effect “potentially-subscribable Watchlists”. A Feed has no effect on your organization until you have subscribed to it - at which point a related Watchlist is enabled in the organization. Once subscribed (and until it’s disabled or unsubscribed), a Watchlist will generate Hits (and Alerts if you have enabled them) for any matches against any of the IOCs in any of that Watchlist’s enabled Reports.

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 record. 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.
