About Hunt.io

Hunt.io integration with CTIX provides actionable threat intelligence by tracking malicious infrastructure across the Internet. With this integration, organizations gain the tools and context needed to proactively identify hidden threats and defend against advanced cyberattacks.

Intel Exchange integrates with Hunt.io to retrieve threat intel feeds about the following threat objects:

  • Infrastructure

  • Malware

  • Observed Data (Autonomous System Observable)

  • Location

  • Indicator (IPv4 and Domain)

Configure Hunt.io as API Feed Source

Configure Hunt.io as an API feed source to receive threat data feeds.

Before you Start  

  • You must have the View API Feed, View Feed Source, Create Feed Source, and Update Feed Source permissions in CTIX.

  • You must have the base URL and API key of your Hunt.io account.

    Note

    Ensure that the API key includes the permissions to retrieve threat data. If the API key does not have permission to retrieve a threat data feed, then the respective feed channel is disabled automatically and displays a connection error.

Steps  

To configure Hunt.io as an API feed source in CTIX, do the following:

  1. Go to Administration > Integration Management > FEED SOURCES > APIs.

  2. Click Add API source.

  3. Search and select the Hunt.io app.

  4. Click Add Instance.

  5. Enter a unique name to identify the instance name. For example, Hunt.io-Prod.

  6. Enter the base URL of your Hunt.io instance. The default base URL for the Hunt.io app is https://api.hunt.io/.

  7. Enter the API key of your Hunt.io account to authenticate communication between the CTIX and Hunt.io servers.

  8. Select Verify SSL to verify the SSL certificate and secure the connection between the CTIX and Hunt.io servers. By default, Verify SSL is selected.

    Note

    Cyware recommends you select Verify SSL. If you disable this option, CTIX may configure an instance for an expired SSL certificate. This may not establish the connection properly and CTIX will not be able to notify you in case of a broken or improper connection.

  9. Click Save.

The Hunt.io instance is configured and you can view the Hunt.io feed channels. You can configure multiple instances by clicking Manage > Add More.

Configure Hunt.io Feed Channels

Configure the feed channels to retrieve threat data feeds from Hunt.io and store the feeds in a collection.

Steps 

To configure the Fetch C2 Feeds channel, do the following:

  1. Go to Administration > Integration Management > FEED SOURCES > APIs.

  2. Search and select the Hunt.io app.

  3. Click the ellipsis on the top right corner and select Manage.

  4. Click Manage Feed Channels.

  5. Select the Fetch C2 Feeds channel and enable the toggle.

  6. Enter the date and time to start polling feeds. Select a date within 15 days from the current date.

  7. Enter the name of the collection to group the feed data. For example, Hunt.io Indicators Feeds. CTIX creates the collection and stores all the feeds from the feed channel.

  8. Select from one of the following Polling Cron Schedule types to define when to poll the data:

    • Manual: Allows you to manually poll from the source collection.

    • Auto: Allows you to automatically poll for threat intel from sources at specific time intervals. The default polling cron schedule is Auto.

      • Enter a frequency in minutes between 60 and 10080 minutes in Polling Time. The default polling time is 240 minutes.

  9. Set a default TLP and confidence score to assign to the feeds that do not have a TLP and confidence score already assigned. By default, the default TLP and confidence score are set to Amber and 100 respectively.

  10. Select any tags to identify and categorize the feeds.

  11. Click Save.

The feed channel is configured and you can poll feeds from the channel. You can enable the other feed channels, poll feeds, and view the feeds. For more information, see API Integrations.

Test Feed Channel Connectivity

Test the connectivity of the Hunt.io API feed channels to ensure that the connection with the correct API endpoint is established and that you have permission to poll feeds.

Before you Start

  • Ensure that the Hunt.io API integration is enabled.

  • Ensure that the feed channel for which you want to test connectivity is enabled.

Steps

To test the connectivity of a feed channel, follow these steps:

  1. Go to Administration > Integration Management. In Feed Sources, click APIs.

  2. Search and select the Hunt.io app.

  3. On a feed channel, click the vertical ellipses and select View Details.

  4. In the Working Status section, click Test Connectivity.

If the connection is established, then the working status shows Running. If the connectivity is broken, then the working status shows a Connection Error. Hover over the tooltip next to Connection Error to view the error code.

Note

When a feed channel loses connectivity, it is automatically disabled, and the system attempts to restore connectivity three times per hour. If the connectivity is successfully restored, the feed channel is automatically re-enabled.

To understand the error code and troubleshoot broken connectivity, see Troubleshoot Integrations.

Hunt.io Feed Channels

CTIX provides multiple channels to poll feeds from Hunt.io. The following table lists all the feed channels and the Hunt.io API endpoints used for each feed channel.
