Overview of Indicators of Compromise (IoCs): Indicators of Compromise (IoCs) are pieces of evidence that suggest a system may have been compromised. These can include unusual network traffic patterns, the presence of known malicious files, or other suspicious activities.

FortiAnalyzer's Role: FortiAnalyzer aggregates logs from various Fortinet devices to provide comprehensive visibility and analysis of network events. It uses these logs to identify potential IoCs and compromised hosts.

Relevant Log Types:

DNS Filter Logs:

DNS requests are a common vector for malware communication. Analyzing DNS filter logs helps in identifying suspicious domain queries, which can indicate malware attempting to communicate with command and control (C2) servers.

Understanding the Playbook and its Components:

The exhibit shows a playbook in which an event trigger starts actions upon detecting a malicious file.

The initial tasks in the playbook include CREATE_INCIDENT and GET_EVENTS.

Analysis of Current Tasks:

EVENT_TRIGGER STARTER: This initiates the playbook when a specified event (malicious file detection) occurs.

CREATE_INCIDENT: This task likely creates a new incident in the incident management system for tracking and response.

GET_EVENTS: This task retrieves the event details related to the detected malicious file.

Objective of the Next Task:

The next logical step after creating an incident and retrieving event details is to update the incident with the event data, ensuring all relevant information is attached to the incident record.

This helps SOC analysts by consolidating all pertinent details within the incident record, facilitating efficient tracking and response.

Evaluating the Options:

Option A:Update Asset and Identity is not directly relevant to attaching event data to the incident.

Option B:Attach Data to Incident sounds plausible but typically, updating an incident involves more comprehensive changes including status updates, adding comments, and other data modifications.

Option C:Run Report is irrelevant in this context as the goal is to update the incident with event data.

Option D:Update Incident is the most suitable action for incorporating event data into the existing incident record.

Conclusion:

The next task in the playbook should be to update the incident with the event data to ensure the incident reflects all necessary information for further investigation and response.

Comprehensive and Detailed Explanation From FortiSOAR 7.6., FortiSIEM 7.3 Exact Extract study guide:

Based on the official documentation forFortiSIEM 7.3(which utilizes the MITRE ATT&CK mapping for incident correlation) andFortiSOAR 7.6(which uses these tactics for incident classification and playbook triggering):

Reconnaissance (Tactic TA0043):This tactic consists of techniques that involve adversaries actively or passively gathering information that can be used to support targeting. In this scenario, the attacker identifies "employee names, roles, and email patterns from public press releases." This is categorized underGather Victim Org Information (T1591)andSearch Open Technical Databases (T1596). Since this activity happens prior to the compromise and involves gathering intelligence, it is strictly Reconnaissance.

Initial Access (Tactic TA0001):This tactic covers techniques that use various entry vectors to gain an initial foothold within a network. The act of sending "tailored emails... to recipients to review an attached agenda using a link" is the definition ofPhishing: Spearphishing Link (T1566.002). This is the specific delivery mechanism used to gain the initial entry.

Why other options are incorrect:

Discovery (B):This tactic involves techniques an adversary uses to gain knowledge about the internal network after they have already gained access. Since the attacker is looking at public press releases, they are operating outside the perimeter.

Defense Evasion (D):This tactic consists of techniques that adversaries use to avoid detection throughout their compromise. While using an external link might bypass some basic reputation filters, the primary goal described in the report is the act of establishing contact and access, which is the core of the Initial Access tactic.
