312-50v13 Exam Dumps - Certified Ethical Hacker Exam (CEHv13)

The correct answer is Follow TCP Stream. CEH packet analysis and sniffing material explains that Wireshark can reconstruct an application conversation from captured packets belonging to the same TCP session. When investigating HTTP logins, this feature is especially useful because it allows the analyst to view the reassembled request and response content in readable sequence rather than examining individual packets one by one. If credentials are being transmitted in cleartext over HTTP, Follow TCP Stream can reveal them directly within the reconstructed session. Filtering by IP address or by protocol can narrow the visible traffic set, which is helpful, but those functions alone do not reconstruct the full conversation. Monitoring specific ports is also less precise for understanding the actual payload content. CEH guidance emphasizes that once suspicious or relevant traffic is identified, stream reconstruction is a powerful method for analyzing what data was exchanged between client and server. Since Thomas is specifically trying to isolate and read unencrypted HTTP authentication exchanges during login sessions, Follow TCP Stream is the Wireshark feature that best supports both visibility and interpretation of those credentials in context.

The correct answer is B because massive outbound HTTPS traffic is a strong indicator of data exfiltration, especially when it is designed to blend into normal web traffic. In CEH attack lifecycle concepts, exfiltration occurs after an attacker gains access and can quietly extract protected resources or sensitive data from the environment. The retrieved CEH-aligned material describes exfiltration as the phase where an attacker with elevated access can “quietly extract data,” and notes that exfiltration can occur silently. HTTPS is commonly allowed outbound in enterprise networks, so attackers may use it as a covert or low-noise channel to move stolen files, credentials, database dumps, or archives to an external server. The guide material also notes that malware often uses SSL over port 443 or other easy- to-hide mechanisms rather than obvious suspicious ports. DoS usually creates service disruption, scanning generates probing patterns, and reconnaissance focuses on information gathering. Massive hidden outbound HTTPS most likely indicates data exfiltration.

CEH’s social engineering principles highlight psychological manipulation techniques such as authority, urgency, trust exploitation, and impersonation. In this scenario, the attacker leverages “perceived authority,” a powerful influence tactic where the social engineer poses as someone with legitimate power or sanctioned access—such as a technician, auditor, or vendor representative. CEH emphasizes that referencing real employee names, using technical terminology, and impersonating trusted third-party partners increases believability and reduces verification resistance. The receptionist’s acceptance of the attacker’s presence without verifying credentials matches classical authority-based exploitation. Leaked credentials, physical security logs, and network segmentation issues do not relate to human-layer social engineering. The situation clearly reflects the manipulation of trust and authority as described in CEH’s psychological attack vectors.

CEH v13 defines the five phases of ethical hacking as a structured methodology that mirrors real-world attack progression:

Reconnaissance – Information gathering

Scanning – Identifying live hosts, ports, and vulnerabilities

Gaining Access – Exploiting vulnerabilities

Maintaining Access – Establishing persistence

Covering Tracks – Removing evidence

Option C matches this exact sequence. CEH v13 emphasizes that understanding this order is critical for both attackers and defenders, as it enables systematic testing and effective mitigation strategies.

All other options misplace phases and contradict the CEH methodology.

CEH v13 describes Cross-Site Request Forgery (CSRF) as an attack in which an authenticated user ' s browser is tricked into submitting unauthorized actions to a trusted application without the user ' s intent. CSRF exploits the fact that browsers automatically include stored session cookies when sending requests to a domain the user is logged into. In this scenario, the attacker creates a malicious form that triggers an unwanted funds transfer. Since the application does not validate request origin, enforce CSRF tokens, or require secondary verification, it processes the attacker ' s forged request as if it came legitimately from the victim. CEH emphasizes that CSRF differs from XSS because no malicious script executes on the target website; instead, the attacker leverages the victim’s authenticated session. This is distinct from session fixation (Option A), replay attacks (Option B), and XSS (Option D). The described behavior aligns precisely with CSRF exploitation.

The correct answer is Nikto. CEH web server security coverage identifies Nikto as a specialized open-source web server vulnerability scanner designed to assess HTTP and HTTPS services for dangerous files, insecure default content, outdated server versions, and version-specific problems. The scenario mentions examination of server headers, detection of installed web server software, checks for outdated components, identification of dangerous files and misconfigurations, SSL support, and exportable reporting. Those characteristics align closely with Nikto’s typical use in CEH-style web server assessments. OpenVAS, Nessus, and Qualys VM are broad vulnerability management platforms with much wider enterprise coverage, but the question describes a focused HTTP-server scanner rather than a full-spectrum infrastructure scanner. CEH materials frequently present Nikto in the context of web server enumeration and vulnerability discovery after the tester has identified the target web platform. It is especially useful for quickly checking internet-facing servers for known risky files, weak configurations, and outdated software. Because the assessment is centered on the specific exposure of web servers and matches the recognized feature set of Nikto, option D is the best answer.

An HTTP Flood attack is an Application Layer (Layer 7) DDoS attack, as defined in CEH v13. In this attack, the adversary sends a massive number of seemingly legitimate HTTP GET or POST requests to exhaust server resources such as CPU, memory, and application threads.

CEH v13 emphasizes that HTTP floods are difficult to detect because they mimic normal user behavior and often bypass traditional network-layer defenses.

Other attacks operate at lower layers:

ICMP, UDP, and SYN floods target network and transport layers.

The correct answer is B because the scenario exactly describes a pass-the-hash attack. In Windows environments, NTLM authentication uses password hashes as part of the authentication process. In a pass-the-hash attack, the attacker or authorized penetration tester does not need to recover the cleartext password. Instead, they extract the NTLM hash and reuse that hash directly to authenticate to another system or service. CEH-aligned system hacking material explains that Windows stores password hash values and that an attacker can steal a hash and send it instead of cracking the password. This is different from brute force, where many password guesses are attempted until the correct password is found. It is also different from Kerberoasting, which targets Kerberos service tickets for offline cracking. “Replay attack” is a broader term, but the precise Windows/NTLM technique described here is pass-the-hash. Therefore, option B is the best answer.
