The tool described is most consistent with Bettercap. Bettercap is a lightweight, extensible framework commonly used in controlled security testing for man-in-the-middle (MITM) operations on local networks. It supports ARP spoofing/ARP poisoning to position the attacker between victims and gateways, enabling interception of traffic. It also supports DNS manipulation/spoofing (e.g., redirecting domain lookups to attacker-controlled destinations) and packet injection capabilities for modifying or inserting traffic.
Importantly, it provides an interactive interface that allows real-time session visibility and control, which matches the scenario's emphasis on interactive monitoring while intercepting internal web application traffic.
The objective described-capturing and manipulating session tokens in transit-is consistent with a MITM platform that can observe HTTP traffic (or influence traffic where TLS is not properly enforced or where testing includes trusted certificates in a lab). Bettercap's design as an "all-in-one" local network attack and monitoring tool makes it a typical choice for demonstrating risks from weak network segmentation, insecure DNS, lack of HTTPS/HSTS, or insufficient endpoint protections against ARP spoofing.
Why the other options are less suitable:
Wireshark (A) is primarily a packet analyzer/sniffer; it does not inherently perform ARP spoofing, DNS manipulation, or injection as an active MITM tool.
Hetty (B) and Caido (C) are web-focused interception/testing tools (proxy-style workflows). They can intercept HTTP/S when configured as a proxy, but they do not natively specialize in LAN-layer ARP spoofing and DNS manipulation for transparent MITM in the same way as Bettercap.
Therefore, the most likely tool is D. Bettercap.

CEH v13 identifies kernel-level rootkits as among the most dangerous malware types. Because they operate at the lowest OS level, they can hide processes, files, and system calls.
CEH v13 states that the only guaranteed remediation is a complete system wipe and clean OS reinstallation from a trusted source. Attempting removal risks incomplete eradication.
Powering down alone does not remove the rootkit. Honeypots are for detection, not remediation. Tailored removal tools may fail at kernel depth.
Thus, Option C is correct.

This question describes a classic example of Tautology-Based SQL Injection, a subcategory of SQL Injection attacks which fall under Web Application Hacking in the CEH curriculum.
In a tautology-based SQL injection, the attacker injects a SQL fragment that always evaluates to true, thus bypassing the authentication mechanism. The string ' C 'll-T; - is a malformed variant, possibly meant to represent ' OR '1'='1'; --, which is one of the most basic and widely recognized tautology-based injection payloads. When injected into a vulnerable SQL query, this kind of input manipulates the WHERE clause of the query so that it always evaluates to true, regardless of the original conditions.
Here's how it works:
If the SQL query is:
SELECT * FROM users WHERE username = '$username' AND password = '$password'; And the attacker inputs:
' OR '1'='1'; --
The query becomes:
SELECT * FROM users WHERE username = '' OR '1'='1'; --' AND password = ''; This results in the execution of:
SELECT * FROM users WHERE '1'='1';
Which always evaluates to true, thereby bypassing authentication and allowing unauthorized access.
This method does not rely on error messages (Error-Based), timing delays (Time-Based Blind), or UNION statements (Union-Based). Its goal is to exploit logic within the query structure itself using boolean-based manipulation.
According to EC-Council's CEH v13 Module: Web Application Hacking, understanding tautology-based injection is critical because it's one of the most common ways attackers bypass login forms on poorly secured web applications.

The correct answer is B. Social Engineering because the attacker's primary method is manipulating people- not exploiting a technical vulnerability-to obtain information that can enable initial access. In CEH-aligned security concepts, social engineering is defined by the use of deception, impersonation, and psychological influence to persuade victims to reveal sensitive information, perform actions, or bypass normal security procedures. Here, the ethical hacker "poses as a recruiter" on a professional networking site, which is a classic impersonation / pretexting approach. The goal is to build credibility and trust so employees voluntarily disclose internal details that should not be shared externally.
The information gathered-"internal software and VPN setup"-is exactly the sort of intelligence attackers seek during reconnaissance and pre-attack planning. VPN details, remote access workflows, authentication methods, and internal tooling can be used to craft highly convincing phishing messages, identify weak points (such as outdated clients or exposed portals), or target specific employees and administrators. In a real intrusion, this social engineering-driven intelligence collection often precedes credential harvesting, password spraying, MFA fatigue attempts, or tailored malware delivery.
Why the other options are less correct: System and Network Attacks refer to direct technical exploitation such as scanning, sniffing, or attacking services and protocols; the scenario contains none of that. Information Leakage describes the condition where sensitive data is exposed (for example, public documents, misconfigured repositories, error messages), but the scenario focuses on active interpersonal manipulation to extract information. Corporate Espionage is a broader motive/category describing theft of trade secrets, often by competitors or nation-state actors; while social engineering can be used in espionage, the question asks about the method of information gathering, which is clearly social engineering.
Therefore, the threat method demonstrated is social engineering (pretexting/impersonation via a recruiter persona).

The Certified Ethical Hacker (CEH) Incident Response lifecycle begins with Identification, followed by containment, eradication, recovery, and lessons learned. CEH documentation stresses that understanding the scope and nature of an incident is critical before taking disruptive action.
Option A is the correct initial response because it focuses on real-time monitoring and log analysis, which are essential during the identification phase. CEH materials emphasize analyzing logs, authentication failures, and traffic anomalies to confirm whether an incident has occurred and determine the attacker's techniques, persistence level, and impact.
Option B, while valuable, is more appropriate after initial identification. Conducting deep outbound traffic audits without first understanding the attack vector can delay containment decisions.
Option C is premature. CEH warns that changing credentials too early may alert the attacker and cause them to escalate or destroy evidence.
Option D represents a containment strategy, not an initial response. CEH guidelines advise against immediately disconnecting systems unless there is confirmed active data exfiltration that cannot be otherwise controlled, as this may disrupt business operations and erase volatile forensic evidence.
Therefore, the CEH-approved approach is to monitor, analyze, and identify the incident before moving to containment and eradication.
