Task 1. Introduction to XSOAR & Phishing

In this task, take a moment to review the limitations of current solutions in effectively addressing phishing attacks.

1. What is phishing?

   Phishing is a type of social engineering that primarily occurs through email. Attackers create fraudulent emails that mimic legitimate communication in order to deceive recipients.

2. What are some current limitations with today's systems in addressing phishing emails?

   Responding to phishing emails can be a time-consuming and complex task. These tasks often require multiple tools and involve manual actions that are error prone.

3. How does Cortex XSOAR address these limitations?

   Cortex XSOAR effectively addresses challenges associated with phishing emails through its comprehensive automation and orchestration capabilities.
   By combining automation, orchestration, and integrations, Cortex XSOAR significantly enhances the efficiency, accuracy, and speed of responding to phishing emails, effectively mitigating the associated challenges.

Task 2. Investigating Incidents

In this task, learn about incidents within the Cortex XSOAR platform. An incident refers to a security event or breach that requires investigation, analysis, and remediation. When an incident occurs, XSOAR provides a centralized platform for managing and coordinating the response efforts.

Step 1. Generate Phishing Incident

In this step, create an incident for the phishing attack. Creating incidents allows you to choose a scenario that best fits your specific use-case.

1. Access Cortex XSOAR using the URL and credentials below.

   Key	Value
   Console
   Username
   Password

   It may take several minutes for the XSOAR console to become accessible.

2. Go to Incidents. Set the Created range to All times.

   

3. Click New Incident to create a new incident.

   After creating an incident, the incident ID will be generated. You can view more details about incidents by selecting the incident's correlating ID number.

4. Set the workshopscenario to Phishing Campaign and Type to Scenario. Then, click Create New Incident.

   It may take several minutes for the new incident to appear. This is because XSOAR is correlating and processing the data with associated Work Plan tasks.

5. While waiting for the incident to generate, open any existing incident to view more information about it.

   All of the incidents in this lab have been generated by Cortex XDR and are ingested by Cortex XSOAR.

Step 2. Investigate Phishing Incident

In this step, investigate the phishing incident that was created in the previous step, including the incident's timeline, status, and associated evidence.

1. While within Incidents, enter the search below to filter for incidents that use the Email Phishing playbook.

   playbook:"Email Phishing"

   

2. Select the most recent incident to view more information about it.

   Notice the Status of the incident is listed as Active. This is because the Work Plan associated with this incident type has not been completed, or is waiting for manual intervention.

3. Click Case Info tab. Take time to review the case details, timeline, notes, and evidence.

   The incident information panel provides a summary of the incident with available actions that you can take.

4. Click the Investigation tab. Review the contents of the e-mail, including any associated indicators, and incident files.

   The Investigation tab displays a rasterized image of the phishing email, the email body, and information about the indicators.

Task 3. Incident War Room & Work Plan

In this task, work within XSOAR War Rooms and Work Plans to understand and remediate phishing incidents.

Step 1. Incident War Room

A War Room centralized workspace that facilitates collaboration, incident response, and threat intelligence among security teams. In this step, navigate to the incident's War Room to view a consolidated pane of all the events related to the phishing incident.

1. The War Room tab has a notification icon, indicating manual intervention is required for this particular incident. Click the War Room tab.

   War Room provides a unified view of all ongoing security incidents, allowing teams to coordinate their efforts, track progress, and resolve incidents more efficiently.

2. Take time to scroll through the events associated with the incident.

3. At the bottom, a message states the execution of the Work Plan has been paused.

   There may be several reasons for pausing tasks in a Work Plan. For example, Work Plans may be paused intentionally until clear communication has been established across SOC teams.

4. Click Complete in Task pane → Open in Work Plan.

   Work Plans use playbooks with predefined workflows/instructions to automate and orchestrate SOC operations and incident response.

Step 2. Incident Work Plan

In this step, navigate to the incident's Work Plan to view the steps and actions taken to respond to the phishing incident. The Work Plan provides a visual representation of the steps and actions to be taken when responding to specific security incidents or events.

1. The previous step brings you to a incomplete task within the Work Plan tab. The tasks is requesting manual investigation into the email.

   Work Plans outline the steps, tasks, and milestones required to successfully automate security operations and incident response. Completed tasks are marked green and incomplete tasks are marked yellow.

2. Since we already have investigated the email, click Mark Completed.

   Within Task Details, you can add notes about the task, assign the task to other users, or set a due date for the task.

3. The Work Plan should progress the task, Assign and involve appropriate personnel. Click Mark Completed.

   This task provides the option to invite additional team members to collaborate on the incident.

4. The Work Plan should progress the task, Assess severity. Click Mark Completed.

   This task offers the choice to assign varying severity levels based on the gathered information about the incident. This capability allows you to establish distinct steps within the Work Plan, enabling different actions to be taken depending on the assigned severity level.

5. The Work Plan should progress the task, Are the hostnames in the urls being misrepresented? Click Mark Completed.

   This task requires manual intervention to verify whether the URL text in the email differs from the actual hostname. This is a common tactic in phishing attacks, by tricking users into clicking the embedded URL.

6. The Work Plan should now be marked as completed. Feel free to explore any of the tasks in the Work Plan for additional information and insights.

   

Step 3. (Optional) Generate Report

XSOAR offers extensive reporting capabilities out of the box, including pre-built reports and dashboards, it also allows you to create custom reports to suit your specific needs. In this step, create a report about the phishing incident.

1. While within the Incident, go to Case Info → Actions → Report.

   

2. Set Select a tab to generate report from to Case info. Then, click Generate report.

   XSOAR offers a range of report types that can be generated. In addition, you have the option to directly generate reports within the Work Plan and conveniently email them to the relevant teams.

3. Hover over the XSOAR logo on the top left, and click on Dashboards & Reports. Click the Reports tab to download the report to your machine.
