How does Cortex XSOAR expedite the handling of a phishing incident?

Cortex XSOAR is designed to streamline incident response processes, particularly for phishing incidents, by utilizing automation and orchestration. The correct choice involves identifying every mailbox that received the phishing email and creating cases for those instances. This capability is crucial because it allows organizations to have a comprehensive view of the impact of the phishing attack across their email environment.

By creating individual cases for each mailbox, the system facilitates a more organized and efficient investigation. Security teams can prioritize their responses based on the scope of the phishing incident, as each case may require specific actions, such as user communication, further investigation, or remediation steps. This approach is more effective than manual processing and ensures a faster response to contain potential threats, making the entire process more efficient.

In contrast, simply notifying staff about a phishing attack ensures they are aware but does not directly address how to manage the incident effectively. Purging emails from mailboxes that haven't been opened could lead to data loss and might not address those who have already interacted with the phishing content. Automatically responding to the phishing email to unsubscribe is not only ineffective in mitigating the threat but may also confirm to the attacker that the email address is valid, potentially leading to more targeted attacks.
