Single Blog Post to SecureX Casebook

Workflow #0002

This workflow takes a Talos blog post, conducts an investigation into it using Cisco Threat Response, and then puts the results in a SecureX casebook. If a Webex room name and bot token are provided, a message with the investigation’s results will be sent.

This workflow has been updated to use the new "SecureX Token" account key. For more information about this, please see this page. If you want to use legacy authentication, you can import an older version of the workflow.

Important Note

This workflow is an adaptation of the sub-workflow used by the Talos - Get New Blog Posts workflow. Modifying this workflow won’t cause any issues with the other Talos workflow as it’s completely separate. We’re providing this workflow separately in case you want to adapt it for something else or play with it without the complexity of the parent workflow.

Requirements

  • The following system atomics are used by this workflow:
    • Threat Response - Create Casebook
    • Threat Response - Deliberate Observable
    • Threat Response - Enrich Observable
    • Threat Response - Inspect for Observables
    • Webex - Search for Room
    • Webex - Post Message to Room
  • The following atomic actions must be imported before you can import this workflow:
    • None
  • The targets and account keys listed at the bottom of the page
  • (Optional) Cisco Webex

Workflow Steps

This workflow is designed to parse a single blog post into a casebook.

  1. Fetch the blog post content and strip out any HTML
  2. Inspect the blog post content for observables
  3. Loop through each observable and get its Threat Response disposition
  4. For observables that weren’t clean, conduct Threat Response enrichment to get sightings
  5. For modules with sightings, build the text to post to Webex
  6. Create the SecureX casebook and, if a teams room is provided, post a message to Webex

Configuration

  • See this page for information on configuring the workflow for Webex
