Scripts#

The Threat Intelligence EclecticIQ Platform App ships with two scripts:

Collection script

  • The script that collects outgoing feed data from EclecticIQ Platform is: eiq_collect_feeds.py.

  • Inputs stanza: [script://$SPLUNK_HOME/etc/apps/SA-EclecticIQ/bin/eiq_collect_feeds.py].

  • By default, the collection script is configured to run every 20

  • minutes (cron schedule: */20 * * * *).

Sightings script

  • The script that sends sightings to EclecticIQ Platform is: eiq_send_sightings.py.

  • Inputs stanza: [script://$SPLUNK_HOME/etc/apps/SA-EclecticIQ/bin/eiq_send_sightings.py].

  • By default, the collection script is configured to run every 15 minutes (cron schedule: */15 * * * *).

Manage scripts#

This section describes how to manage scripts provided with the app.

Enable/disable a script:

  1. In the top navigation bar, click Settings > Data inputs.

  2. Under Local inputs, click Scripts.

  3. In the row of the script you want to enable/disable, go to the Status column.

  4. Click Enable or Disable.

Edit the interval cron expression of a script:

  1. In the top navigation bar, click Settings > Data inputs.

  2. Select Scripts.

  3. Click the script you want to edit.

  4. In the Interval field, change the interval.

  5. Click Save.

For further details on Splunk cron expressions, see the official Splunk documentation on cron expressions and their answers to common questions on cron expressions.

KV store#

The EclecticIQ Platform app creates three KV stores in Splunk:

  • eiq_ioc_list (Downloaded observables)

  • eiq_feed_list (Meta Information about Outgoing Feeds)

  • eiq_alerts (Alerts results)

Warning

Do not manually edit the KV stores.

The collection script writes the downloaded threat intelligence directly to these KV stores, and is search head cluster -aware.

Alerts#

The Threat Intelligence EclecticIQ Platform App comes packaged with two different saved searches. Both are disabled by default, and must be enabled before alerts can be triggered by the app.

List of alerts#

EclecticIQ alert#

The EclecticIQ alert saved search is a plain-text saved search that triggers an alert when it finds matches for observables collected from the connected EclecticIQ Platform instance.

Enabling both EclecticIQ alert and any one of the EclecticIQ tstats Threat Intelligence alerts may produce duplicate results.

Enable alerts#

To enable the saved searches:

  1. Open Splunk Web.

  2. In the top navigation bar, click Settings > All configurations.

  3. In the All configurations page, set the filter to only display entries for EclecticIQ Platform App (SA-EclecticIQ).

    ../../../../_images/splunk-all-configurations-filter.jpg

    Do this by selecting from the drop-down menus next to App:

    • EclecticIQ Platform App (SA-EclecticIQ)

    • Created in the App

  4. Click Enable in the Status column for these saved searches:

    • EclecticIQ alert

    • EclecticIQ tstats Threat Intelligence alert - Domain

    • EclecticIQ tstats Threat Intelligence alert - Email

    • EclecticIQ tstats Threat Intelligence alert - Hash

    • EclecticIQ tstats Threat Intelligence alert - Source/Destination

    • EclecticIQ tstats Threat Intelligence alert - URL

Manage how frequently alerts are run#

You can manage how frequently the saved search for an alert is run by editing the CRON interval for that alert.

To edit the CRON interval of an alert

  1. In the top navigation bar, click Settings > All configurations.

  2. Locate the alert you want to configure, and click on its name.

  3. Edit the contents of the Cron Expression field. Change it to the desired time and date the saved search should run.

Uninstall#

To uninstall the Threat Intelligence EclecticIQ Platform App, open the terminal on your Splunk host and run:

$SPLUNK_HOME/bin/splunk remove app SA-EclecticIQ

Or remove the app directory manually by running:

Warning

Removing data with rm -rf is irreversible.

rm -rf SPLUNK_HOME/etc/apps/SA-EclecticIQ

After the command completes, restart Splunk:

$SPLUNK_HOME/bin/splunk restart
