The Splunk Add-on for Recorded Future is designed specifically for Splunk Enterprise Security.
This Add-on integrates with the Splunk ES Threat Intelligence Framework by adding a feed containing information security threat indicators from Recorded Future. With this added feature, defenders can automate the process of finding connections between internal incidents and external sources. This can work bidirectionally: searching Recorded Future for more context around internally observed indicators, or testing trending indicators from open source reporting against internal data sets.
The Add-on also simplifies the workflow of analysts working within the ES environment by adding contextual actions to the Incident Review and event searching and reporting views. This includes information on IPs, domains, file hashes and CVEs.

To install this Add-on, perform the following steps:
Click the button 'Add new entry' in the "Incident Review -
Event Attributes" section. Add the following Label and Field
combinations:
| Label | Field
| ------------------------------- | ----------------------- |
| RF Risk Score | rf_a_risk |
| RF Triggered Rules | rf_b_rules |
| RF Very Malicious Evidence | rf_evidence_critical |
| RF Malicious Evidence | rf_evidence_malicious |
| RF Suspicious Evidence | rf_evidence_suspicious |
| RF Unusual Evidence | rf_evidence_unusual |
A restart of the Splunk instance will be required once the
installation has completed.
Alternatively, you can download the Add-on using the Splunk Web
interface's "Find more apps online" feature. Steps 5 and onwards above
must still be completed.
After installation, you will need to set up the Add-on for Recorded
Future to communicate with the Recorded Future API.
The setup needs to be run after the upgrade. The API key (previously
called token in our documentation) will not carry over from the old
configuration. The same goes for proxy and loglevel configurations.
Due to the extent of the changes between version 2 and 3 of the app
we recommend that you remove the app directory
($SPLUNK_HOME/etc/apps/TA-recorded_future) and make a fresh install
of the app.
If that is not possible proceed with the instructions below.
The following files and directories can be removed
since they are not used anymore:
From the bin folder:

rf_splunk

default.xmlAny file in the local folder is the result of a
local configuration. These have precedence over the
new settings shipped with the app. Review differences
in each file in the local folder compared to the
new default in the default folder and adjust if
required.
In particular correlation searches in
savedsearches.conf are likely to cause issues if
in place.
Recorded Future has a support web site:

up-to-date ways of contacting support is also available.

New in version 4.0:
- Adaptive responses have been added. These can be used to enrich any supported IOC while performing correlations or in ad-hoc mode.
- Added URL risk lists.
- Improved display of risk information in the Incidents review dashboard.
- Support for custom risk lists from Recorded Future Fusion was added.
- Support for retrieving alerts from Recorded Future was added. A dashboard to view alerts is available.
- Built-in help pages.
- New reports added to view "Latest updates of all risk lists", "All log events from the add-on" and a validation status.
- New options to customize access to Recorded Future's API (custom URL and optional SSL verification).
- Search head cluster synchronization.
Specific for version 4.0.4:
- Issue in Search Head clusters which prevented risk list updates with some configuration settings.
- Issue with retrieving the API key from the storage passwords.
- Increased timeout before entries are purged from the Threat Intelligence framework.
- Added server.conf
The main addition with the 3.0 release is the addition of two new threat lists:
- domains: allows for correlation and enrichment on events from proxies, web application firewalls, DNS servers etc
- hashes: events from anti-virus systems, email gateways, file alteration monitors etc
In addition to the new risk lists there are many other improvements:
- significant performance enhancements
- support for clustering (in particular search head clusters)
- support for running on Windows based Splunk servers
- support for Splunk servers with a non standard management port.
Version 3.1.0 adds a Setup GUI where in addition to the Recorded Future API key it's easy to toggle debug logging or adding proxy information.
Version 3.2.0 adds a verification script that can be run to check that configuration and access needed for the app to work is present.
