About Intel471

CTIX integrates with Intel471 to retrieve up-to-date malware, vulnerability, and adversary intelligence. This integration provides access to intelligence reports and technical data to empower analysts with the context they need to make better decisions on risks and cyber threats.

Use Cases 

  • Utilize technical and contextual data from Adversary Intelligence and Malware Intelligence to make informed decisions and put them into action.

  • Set up the necessary defensive measures using the YARA rules obtained from Intel 471.

  • Gather additional details on significant vulnerabilities to assess their priority for patching.

Benefits 

  • Get real-time and up-to-date intel feeds about emerging cyber threats, threat actors, and malicious activities.

  • Understand the MITRE tactics and techniques used by various threat actors.

Configure Intel471 as an API Feed Source

Configure Intel471 as an API feed source in CTIX to receive adversary intelligence, malware intelligence, indicator, vulnerability intelligence, and finished intel report feeds from Intel471.

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 username and password of your Intel471 account.

    Note

    Ensure that your Group-IB account includes the permissions to threat data feeds using the Group-IB APIs. If you do 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 Intel471 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 Intel471 app.

  4. Click Add Instance.

  5. Enter a unique name to identify the instance name. For example, Intel471-Prod.

  6. Enter the base URL of your Intel471 instance. The default base URL is https://api.intel471.com/v1/.

  7. Enter the username and password of your Intel471 account to authenticate communication between the CTIX and Intel471 servers.

  8. Select Verify SSL to verify the SSL certificate and secure the connection between the CTIX and Intel471 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 Intel471 instance is configured and you can view the Intel471 feed channels. You can configure multiple instances by clicking Manage > Add More.

Configure Intel471 Feed Channels

Configure the respective feed channels to retrieve the adversary intelligence, malware intelligence, indicator, vulnerability intelligence, and finished intel report feeds from Intel471 and store the feeds in a collection.

Steps 

To configure an Intel471 channel, do the following:

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

  2. Search and select the Intel471 app.

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

  4. Click Manage Feed Channels.

  5. Select a feed 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, Intel471 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. (Optional) Enable the Broken Connection Retry Policy to allow the CTIX application to re-attempt any failed connection attempts to your Intel471 account. The system will attempt to connect 10 times.

    • You can enter the retry interval in days, minutes, or weeks and also specify the retry interval and the retry count.

    • Enable Exponential Backoff Entry to progressively extend the wait time between retries for consecutive error responses. For example, for a 10-minute exponential retry interval, the system will re-attempt to connect in 10, 100, 1000, 10000, and so on minutes till the retry count value is met. Use this option to give your system resources some breathing time and resolve any service overload issues.

  12. 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.

Intel471 Feed Channels

CTIX provides multiple channels to poll feeds from Intel471. The following table lists all the feed channels and the Intel471 API endpoints used for each feed channel.
