EC-COUNCIL 312-50V13 Online Questions & Answers

• Question 311:

  A penetration tester discovers that a web application is using outdated SSL/TLS protocols (TLS 1.0) to secure communication. What is the most effective way to exploit this vulnerability?

  A. Conduct a Cross-Site Scripting (XSS) attack on the application
  B. Use a man-in-the-middle (MitM) attack to intercept and decrypt traffic
  C. Perform a brute-force attack on the SSL/TLS handshake
  D. Execute a SQL injection attack on the application's backend
  B. Use a man-in-the-middle (MitM) attack to intercept and decrypt traffic

  ---

  Explanation

  Outdated encryption protocols such as SSL 3.0 and TLS 1.0 contain numerous cryptographic weaknesses, making them susceptible to downgrade attacks, cipher-suite vulnerabilities, and interception. CEH explains that weak SSL/TLS configurations expose encrypted traffic to man-in-the-middle attacks because attackers can exploit vulnerabilities such as BEAST, POODLE, or weak ciphers to decrypt or manipulate data in transit. These flaws compromise confidentiality and integrity, allowing attackers to observe login credentials, session identifiers, or sensitive information. XSS and SQL injection exploit entirely different web vulnerabilities unrelated to encryption strength. Brute-forcing SSL handshakes is computationally infeasible and not relevant. Therefore, a MitM attack targeting the outdated protocol is the most effective exploitation method.

• Question 312:

  Cyber experts conducting covert missions exclusively for national interests are best classified as:

  A. State-sponsored hackers
  B. Organized hackers
  C. Gray hat hackers
  D. Hacktivists
  A. State-sponsored hackers

  ---

  Explanation

  CEH v13 classifies state-sponsored hackers as highly skilled professionals who operate under government direction to conduct espionage, intelligence gathering, sabotage, or cyber warfare. These attackers often target foreign governments, critical infrastructure, and strategic industries.

  The defining characteristics are:

  Government backing

  National or geopolitical objectives

  Advanced resources and long-term campaigns

  Options B, C, and D do not fit. Organized hackers are typically financially motivated cybercriminal groups. Gray hats operate without authorization but not for national interests. Hacktivists pursue ideological or political causes independently.

  CEH v13 explicitly associates covert intelligence operations with state-sponsored actors , making Option A correct.

• Question 313:

  Why are containers less secure than virtual machines?

  A. Host OS on containers has a larger surface attack.
  B. Containers may fulfill disk space of the host.
  C. A compromised container may cause a CPU starvation of the host.
  D. Containers are attached to the same virtual network.
  A. Host OS on containers has a larger surface attack.

  ---

  Explanation

  Comprehensive and Detailed Explanation:

  Containers share the same host operating system kernel, unlike VMs which run isolated kernels. This shared kernel increases the attack surface - a compromise in one container can potentially affect the entire host if kernel-level access is obtained.

  From CEH v13 Courseware:

  Module 14: Hacking Web Applications # Container Security

  "Containers are less secure because they share the host kernel. Attackers compromising the container can exploit vulnerabilities in the shared OS."

• Question 314:

  Allen, a professional pen tester, was hired by xpertTech solutWns to perform an attack simul-ation on the organization's network resources. To perform the attack, he took advantage of the NetBIOS API and targeted the NetBIOS service. B/enumerating NetBIOS, he found that port 139 was open and could see the resources that could be accessed or viewed on a remote system. He came across many NetBIOS codes during enumeration.

  Explanation

  Windows Messenger administration

  Courier administration is an organization based framework notice Windows administration by Microsoft that was remembered for some prior forms of Microsoft Windows.

  This resigned innovation, despite the fact that it has a comparable name, isn't connected in any capacity to the later, Internet-based Microsoft Messenger administration for texting or to Windows Messenger and Windows Live Messenger (earlier named MSN Messenger) customer programming.

  The Messenger Service was initially intended for use by framework managers to tell Windows clients about their networks.[1] It has been utilized malevolently to introduce spring up commercials to clients over the Internet (by utilizing mass-informing frameworks which sent an ideal message to a predetermined scope of IP addresses). Despite the fact that Windows XP incorporates a firewall, it isn't empowered naturally. Along these lines, numerous clients got such messages. Because of this maltreatment, the Messenger Service has been debilitated as a matter of course in Windows XP Service Pack 2.

• Question 315:

  As a budding cybersecurity enthusiast, you have set up a small lab at home to learn more about wireless network security. While experimenting with your home Wi-Fi network, you decide to use a well-known hacking tool to capture network traffic and attempt to crack the Wi-Fi password. However, despite many attempts, you have been unsuccessful. Your home Wi-Fi network uses WPA2 Personal with AES encryption.

  Why are you finding it difficult to crack the Wi-Fi password?

  A. The Wi-Fi password is too complex and long
  B. Your hacking tool is outdated
  C. The network is using an uncrackable encryption method
  D. The network is using MAC address filtering.
  C. The network is using an uncrackable encryption method

  ---

  Explanation

  The network is using an uncrackable encryption method, which makes it difficult to crack the Wi-Fi password. WPA2 Personal with AES encryption is the strongest form of security offered by Wi-Fi devices at the moment, and it should be used for all purposes. AES stands for Advanced Encryption Standard, and it is a symmetric-key algorithm that uses a 128-bit, 192-bit, or 256-bit key to encrypt and decrypt data. AES is considered to be uncrackable by brute force attacks, as it would take an impractical amount of time and computational power to try all possible key combinations12. Therefore, unless you have access to the Wi-Fi password or the encryption key, you will not be able to decrypt the network traffic and crack the password.

  The other options are not correct for the following reasons:

  A. The Wi-Fi password is too complex and long: This option is not relevant because the Wi-Fi password is not directly used to encrypt the network traffic. Instead, the password is used to generate a Pre-Shared Key (PSK), which is then used to derive a Pairwise Master Key (PMK), which is then used to derive a Pairwise Transient Key (PTK), which is then used to encrypt the data. Therefore, the complexity and length of the password do not affect the encryption strength, as long as the password is not easily

  guessed or leaked34.

  B. Your hacking tool is outdated: This option is not plausible because even if your hacking tool is outdated, it would not affect your ability to capture the network traffic and attempt to crack the password. The hacking tool may not support the latest Wi-Fi standards or protocols, but it should still be able to capture the raw data packets and save them in a file. The cracking process would depend on the encryption algorithm and the key, not on the hacking tool.

  D. The network is using MAC address filtering: This option is not feasible because MAC address filtering is a technique that restricts network access and communication to trusted devices based on their MAC addresses, which are unique identifiers assigned to network interfaces. MAC address filtering can prevent unauthorized devices from joining the network, but it cannot prevent authorized devices from capturing the network traffic. Moreover, MAC address filtering can be easily bypassed by spoofing the

  MAC address of an allowed device56.

• Question 316:

  These hackers have limited or no training and know how to use only basic techniques or tools. What kind of hackers are we talking about?

  A. Black-Hat Hackers
  B. Script Kiddies
  C. White-Hat Hackers
  D. Gray-Hat Hackers
  B. Script Kiddies

  ---

  Explanation

  Comprehensive and Detailed Explanation:

  Script Kiddies are individuals with minimal technical skills who use existing tools or scripts developed by others to perform attacks. They generally do not understand the underlying mechanisms and rely on publicly available hacking tools.

  From CEH v13 Official Study Guide:

  Module 1: Introduction to Ethical Hacking # Hacker Types

  "Script kiddies are unskilled attackers who use tools created by others."

• Question 317:

  In a vertical privilege escalation scenario, the attacker attempts to gain access to a user account with higher privileges than their current level. Which of the following examples describes vertical privilege escalation?

  A. An attacker exploits weak access controls to access and steal sensitive information from another user's account with alike privileges.
  B. An attacker leverages a lack of session management controls to switch accounts and access resources assigned to another user with the same permissions.
  C. An attacker uses an unquoted service path vulnerability to gain unauthorized access to another user's data with equivalent privileges.
  D. An attacker escalates from a regular user to an administrator by exploiting administrative functions.
  D. An attacker escalates from a regular user to an administrator by exploiting administrative functions.

  ---

  Explanation

  CEH v13 distinguishes between vertical and horizontal privilege escalation. Vertical escalation occurs when an attacker moves upward in the hierarchy of privileges--such as from a regular user to an administrator or root--by exploiting vulnerabilities, misconfigurations, or insecure privilege boundaries. This allows the attacker to perform tasks that were previously restricted, such as modifying system settings, accessing sensitive data, installing malware, or controlling the entire environment. Horizontal escalation, on the other hand, involves accessing another user's resources at the same privilege level, which the other options describe. Exploiting unquoted service paths or weak access controls may facilitate privilege abuse, but they do not inherently elevate the user to a higher privilege tier unless they specifically lead to administrative execution. The scenario that aligns perfectly with the CEH definition of vertical privilege escalation is the escalation from regular user to administrator.

• Question 318:

  You have compromised a server on a network and successfully opened a shell. You aimed to identify all operating systems running on the network. However, as you attempt to fingerprint all machines in the network using the nmap syntax below, it is not going through:

  invictus@victim_server:~$ nmap -T4 -O 10.10.0.0/24

  TCP/IP fingerprinting (for OS scan) xxxxxxx xxxxxx xxxxxxxxx.

  What seems to be wrong?

  A. The nmap syntax is wrong.
  B. This is a common behavior for a corrupted nmap application.
  C. The outgoing TCP/IP fingerprinting is blocked by the host firewall.
  D. OS Scan requires root privileges.
  D. OS Scan requires root privileges.

  ---

  Explanation

  From CEH v13 Module 03: Scanning Networks, OS fingerprinting with Nmap (using the -O option) requires privileged access to craft raw packets (especially SYN, ACK, and ICMP). On Unix/Linux systems:

  Root privileges are mandatory to perform TCP/IP stack fingerprinting.

  If Nmap is run as a normal user, it fails to initiate OS scanning and exits with a message like "QUITTING!".

  So, in this case, the scan fails because the shell opened does not have elevated (root) privileges.

• Question 319:

  Which algorithm best protects encrypted traffic patterns?

  A. PSA
  B. AES
  C. DES
  D. HMAC
  B. AES

  ---

  Explanation

  AES is the industry-standard symmetric encryption algorithm endorsed by CEH v13 . It provides strong confidentiality and resists traffic analysis when used with proper modes (e.g., CBC, GCM).

  DES is obsolete, HMAC ensures integrity not encryption, PSA is not a standard encryption algorithm.

• Question 320:

  Steven connected his iPhone to a public computer that had been infected by Clark, an attacker. After establishing the connection with the public computer, Steven enabled iTunes WI-FI sync on the computer so that the device could continue communication with that computer even after being physically disconnected. Now, Clark gains access to Steven's iPhone through the infected computer and is able to monitor and read all of Steven's activity on the iPhone, even after the device is out of the communication zone.

  Which of the following attacks is performed by Clark in above scenario?

  A. IOS trustjacking
  B. lOS Jailbreaking
  C. Exploiting SS7 vulnerability
  D. Man-in-the-disk attack
  A. IOS trustjacking

  ---

  Explanation

  An iPhone client's most noticeably terrible bad dream is to have somebody oversee his/her gadget, including the capacity to record and control all action without waiting be in a similar room. In this blog entry, we present another weakness called "Trustjacking", which permits an aggressor to do precisely that.

  This weakness misuses an iOS highlight called iTunes Wi-Fi sync, which permits a client to deal with their iOS gadget without genuinely interfacing it to their PC. A solitary tap by the iOS gadget proprietor when the two are associated with a similar organization permits an assailant to oversee the gadget. Furthermore, we will stroll through past related weaknesses and show the progressions that iPhone has made to alleviate them, and why these are adequately not to forestall comparative assaults.

  After interfacing an iOS gadget to another PC, the clients are being found out if they trust the associated PC or not. Deciding to believe the PC permits it to speak with the iOS gadget by means of the standard iTunes APIs.

  This permits the PC to get to the photographs on the gadget, perform reinforcement, introduce applications and considerably more, without requiring another affirmation from the client and with no recognizable sign. Besides, this permits enacting the "iTunes Wi-Fi sync" highlight, which makes it conceivable to proceed with this sort of correspondence with the gadget even after it has been detached from the PC, as long as the PC and the iOS gadget are associated with a similar organization. It is intriguing to take note of that empowering "iTunes Wi-Fi sync" doesn't need the casualty's endorsement and can be directed simply from the PC side. Getting a live stream of the gadget's screen should be possible effectively by consistently requesting screen captures and showing or recording them distantly.

  It is imperative to take note of that other than the underlying single purpose of disappointment, approving the vindictive PC, there is no other component that forestalls this proceeded with access. Likewise, there isn't anything that informs the clients that by approving the PC they permit admittance to their gadget even in the wake of detaching the USB link.
