A Cortex XSOAR customer has a phishing use case in which a playbook has been implemented with one of the steps blocking a malicious URL found in an email reported by one of the users. What would be the appropriate next step in the playbook?

In the context of incident response related to phishing, changing the user's password is a critical step after blocking a malicious URL. This action helps to mitigate any potential compromise that could have arisen from the phishing attempt. If the malicious URL was indeed a phishing attempt, there is a risk that the user may have inadvertently provided their credentials or other sensitive information to an attacker. By changing the user's password, you effectively reduce the risk of unauthorized access to their account and any associated systems.

Furthermore, this step aligns with best practices in cybersecurity, which emphasize the importance of securing accounts that may be at risk following a phishing incident. Without addressing the user's password, there remains a vulnerability that could be exploited by attackers, even if the URL has been blocked. Thus, changing the password is a proactive measure to protect the user's account and the organization's overall security posture.
