NEW QUESTION # 289
In the context of password security, a simple dictionary attack involves loading a dictionary file into a cracking application such as L0phtCrack or John the Ripper. The brute force method is slow but exhaustive. If you use both brute force and dictionary methods combined to vary words, what would you call such an attack?
- A. BruteDics
- B. Thorough
- C. Hybrid
- D. Full Blown
Answer: C
Explanation:
A hybrid attack combines the benefits of both dictionary and brute-force attacks. It takes words from a dictionary and applies modifications such as:
* Appending or prepending numbers or symbols
* Changing case (e.g., admin # Admin1!)
* Leetspeak substitutions (e.g., p@ssw0rd)
From CEH v13 Official Courseware:
* Module 6: Malware Threats
* Topic: Password Cracking Methods
CEH v13 Study Guide states:
"A hybrid attack is a combination of dictionary and brute-force techniques. It takes dictionary words and mutates them to cover common variations, making it more effective than pure dictionary attacks." Incorrect Options:
* A/B/D: These are not standard terminology in cryptographic or password auditing literature.

NEW QUESTION # 290
A university's online registration system is disrupted by a combined DNS reflection and HTTP Slowloris DDoS attack. Standard firewalls cannot mitigate the attack without blocking legitimate users. What is the best mitigation strategy?
- A. Deploy an Intrusion Prevention System (IPS) with deep packet inspection
- B. Configure the firewall to block all incoming DNS and HTTP requests
- C. Increase server bandwidth and implement basic rate limiting
- D. Utilize a hybrid DDoS mitigation service that offers both on-premises and cloud-based protection
Answer: D
Explanation:
CEH v13 explains that multi-vector DDoS attacks, especially those combining volumetric reflection (DNS amplification) with application-layer exhaustion (Slowloris), require multi-layered mitigation. Standard firewalls and IPS devices cannot handle large-scale distributed attacks without causing collateral damage to legitimate traffic. CEH emphasizes the need for hybrid DDoS protection, combining on-premises appliances for real-time local filtering with cloud-based scrubbing centers capable of absorbing massive volumetric floods. Cloud scrubbing removes malicious traffic upstream, while on-prem devices mitigate application-layer anomalies. Increasing bandwidth (Option A) is ineffective against reflection attacks. IPS (Option B) cannot handle Slowloris-style partial requests at scale. Blocking all external DNS/HTTP (Option C) would deny service to legitimate users. The correct CEH-aligned solution is hybrid DDoS mitigation services.

NEW QUESTION # 292
An ethical hacker needs to gather sensitive information about a company's internal network without engaging directly with the organization's systems to avoid detection. Which method should be employed to obtain this information discreetly?
- A. Use port scanning tools to probe the company's firewall
- B. Exploit a public vulnerability in the company's web server
- C. Perform a WHOIS lookup on the company's domain registrar
- D. Analyze the organization's job postings for technical details
Answer: D
Explanation:
CEH v13 stresses the importance of passive reconnaissance when the goal is to avoid any interaction with the target's systems. Job postings frequently reveal detailed information such as internal technologies, OS platforms, security tools, IDS brands, virtualization environments, scripting languages, and cloud services.
CEH explicitly notes job ads as one of the richest passive intelligence sources because organizations inadvertently disclose their tech stack, often mentioning required experience with specific network components, databases, protocols, or internal tools. Options B and D involve direct interaction, violating the passive reconnaissance requirement. WHOIS lookups (Option C) provide DNS registrar information but do not reveal internal network details. Job postings, social media recruitment materials, and HR documentation are discussed in CEH as critical OSINT resources used during the footprinting phase to gather actionable intelligence while maintaining complete stealth. Thus, analyzing job postings is the correct method.
NEW QUESTION # 293
The collection of potentially actionable, overt, and publicly available information is known as
- A. Real intelligence
- B. Human intelligence
- C. Social intelligence
- D. Open-source intelligence
Answer: D
Explanation:
Open-source intelligence (OSINT) refers to the process of collecting and analyzing information from publicly available sources. This can include social media, websites, press releases, job boards, government databases, and more.
OSINT is a crucial part of the reconnaissance phase in ethical hacking and penetration testing, where attackers or analysts gather intel without directly interacting with the target system.
Reference - CEH v13 Official Study Guide:
Module 2: Footprinting and Reconnaissance
Quote:
"OSINT is derived from public sources and includes blogs, websites, public records, and social networks. It helps attackers or analysts understand the target's digital footprint." Incorrect Options Explained:
B). "Real intelligence" is not a cybersecurity term.
C). Social intelligence refers to interpersonal awareness, not cyber reconnaissance.
D). Human intelligence (HUMINT) involves person-to-person intel, not publicly available data.

NEW QUESTION # 294
You are Evelyn, an ethical hacker at LoneStar Health in Austin, Texas, engaged to investigate a recent compromise of archived patient records. During the investigation you recover a large set of encrypted records from a compromised backup and, separately, obtain several original template records (standard headers and form fields) that correspond to some entries in the encrypted set. You plan to use these paired examples (the original templates and their encrypted counterparts) to attempt to recover keys or deduce other plaintext values. Which cryptanalytic approach is most appropriate for this situation?
- A. Ciphertext-only attack
- B. Chosen-plaintext attack
- C. Known-plaintext attack
- D. Chosen-ciphertext attack
Answer: C
Explanation:
The correct answer is B. Known-plaintext attack because the scenario explicitly provides paired samples of plaintext and ciphertext for the same underlying data. In a known-plaintext attack, the analyst possesses one or more examples where the original message (plaintext) is known and the corresponding encrypted output (ciphertext) is also available. These pairs can be used to analyze the cipher's behavior, validate hypotheses about modes/parameters, and-depending on the algorithm, implementation weaknesses, and key management-attempt to recover the encryption key or decrypt other ciphertexts encrypted under the same key.
Here, Evelyn has "original template records (standard headers and form fields)" and their "encrypted counterparts" in the stolen backup set. Medical record formats commonly contain predictable structures (fixed headers, repeated field names, standardized forms), which increases the likelihood of having accurate known plaintext segments. With enough known plaintext/ciphertext pairs, an attacker may identify patterns caused by weak encryption choices, reused keys, reused IVs/nonces, insecure modes (e.g., ECB revealing structure), or flawed custom crypto. Even when strong algorithms are used, known-plaintext material can still be valuable for confirming the encryption scheme and detecting implementation errors.
Why the other options are not correct: Ciphertext-only assumes the attacker has only encrypted data and no plaintext examples-contradicted by the templates. Chosen-plaintext requires the ability to submit arbitrary plaintexts to an encryption oracle and receive ciphertexts, which the scenario does not indicate. Chosen- ciphertext requires the ability to submit ciphertexts to a decryption oracle and observe outputs, also not described.
Because Evelyn has real, matching plaintext-ciphertext pairs from the same dataset, the most appropriate cryptanalytic approach is a known-plaintext attack.
NEW QUESTION # 295
As part of an insider threat simulation at a multinational insurance firm, lead red teamer John is asked to assess whether internal directory services are exposing sensitive user data. Gaining limited VPN access, he begins probing port 389 on a staging environment connected to the main domain infrastructure. After discovering that anonymous binds are accepted by the directory service, John launches a utility from his Kali machine that allows command-line interaction with directory entries. He structures his query to search for user objects with associated organizational units. Moments later, John reviews the output which includes usernames, group memberships, and departmental hierarchies all retrieved without authentication.
Which tool is John MOST likely using to perform this enumeration?
- A. ldapsearch
- B. smtp-user-enum
- C. nbtstat -A
- D. dig AXFR
Answer: A
Explanation:
D: The scenario describes LDAP enumeration over port 389 with anonymous bind allowed. In CEH coverage, LDAP is a directory access protocol commonly used by enterprise directory services, including Active Directory via LDAP interfaces. When anonymous bind is enabled or misconfigured access controls allow broad read permissions, an attacker can query directory objects without valid credentials and extract valuable reconnaissance data such as user accounts, group membership, organizational units, and directory structure. That is exactly what John is doing: connecting to LDAP, performing searches for user objects, and retrieving organizational information and group relationships.
The Kali utility that fits this behavior is ldapsearch. It is a standard command-line LDAP client used to bind to an LDAP server and execute directory queries using LDAP filters and a base DN. With anonymous bind, ldapsearch can run queries like searching for objectClass=user and requesting attributes such as cn, sAMAccountName, memberOf, and organizational details. CEH materials emphasize LDAP enumeration as a high-value recon step because it helps map the domain, identify privileged groups, and select targets for later attacks, especially when directory permissions are overly permissive.The other options do not match LDAP directory interaction. smtp-user-enum targets SMTP for user enumeration through mail server responses. nbtstat -A queries NetBIOS name tables, typically for host and share-related information, not LDAP directory trees. dig AXFR attempts DNS zone transfers, which is DNS reconnaissance, not directory service enumeration. Therefore, ldapsearch is the most appropriate tool for this anonymous LDAP enumeration on port 389.
NEW QUESTION # 296
You are a penetration tester hired to evaluate the security posture of a regional manufacturing company's network devices. During your assessment, you discover that one of the core routers allows external administrative access without requiring a password. Additionally, the router communicates with other devices using a protocol that does not provide encryption or validation. Based solely on these observations, which of the following network device vulnerabilities is most clearly present?
- A. Lack of password protection
- B. Insecure routing protocols
- C. Firewall vulnerabilities
- D. Lack of authentication
Answer: D
Explanation:
The most clearly demonstrated vulnerability is Lack of authentication. In CEH-aligned network device security principles, authentication is the fundamental control that verifies a user or device is permitted to access administrative functions or participate in trusted communications. The scenario states that the router allows external administrative access without requiring a password. That directly indicates that authentication is not being enforced for management access, meaning an unauthorized user could potentially gain administrative control simply by reaching the management interface.
The second observation reinforces the same core weakness in a different context: the router uses a protocol that provides neither encryption nor validation. In CEH terms, "validation" in routing and management protocols commonly refers to authentication and integrity checks, ensuring that updates or communications are sent by trusted peers and not altered in transit. When a protocol lacks validation, an attacker may be able to inject rogue updates, impersonate a trusted neighbor, or manipulate routing behavior, depending on the protocol and topology. While this could also be described as "insecure routing protocols," the question asks what vulnerability is most clearly present based on both observations together. The common denominator is the absence of authentication controls: no password for admin access and no validation for device-to-device protocol exchanges.
"Lack of password protection" addresses only the first issue and is narrower. "Firewall vulnerabilities" is not evidenced. Therefore, the clearest and most comprehensive vulnerability indicated by the observations is Lack of authentication.
NEW QUESTION # 297
Which address translation scheme would allow a single public IP address to always correspond to a single machine on an internal network, allowing "server publishing"?
- A. Dynamic Network Address Translation
- B. Static Network Address Translation
- C. Overloading Port Address Translation
- D. Dynamic Port Address Translation
Answer: B
Explanation:
Static Network Address Translation (Static NAT) allows a single private IP address to be mapped to a single public IP address. This one-to-one mapping ensures that the same internal machine is always reachable through the same external IP address, which is crucial for "server publishing" - making internal servers (e.g., web servers, FTP servers) accessible from the internet.
From CEH v13 Courseware:
* Module 03: Scanning Networks
* Topic: Network Address Translation
* Section: Types of NAT
CEH v13 Study Guide states:
"Static NAT provides a fixed translation of a private IP address to a public IP address. It is commonly used when an internal server must always be accessible from the Internet using a consistent IP address - this is known as server publishing." Incorrect Options:
* A. Overloading PAT: Multiple private IPs share a single public IP using port numbers - not suited for static mappings.
* B. Dynamic PAT: Similar to overloading; used for outbound traffic only.
* C. Dynamic NAT: Assigns a public IP from a pool; the mapping can change, not suitable for server publishing.

NEW QUESTION # 298
A penetration tester suspects that a web application's product search feature is vulnerable to SQL injection.
The tester needs to confirm this by manipulating the SQL query. What is the best technique to test for SQL injection?
- A. Inject a malicious script into the search field to test for Cross-Site Scripting (XSS)
- B. Input 1 OR 1=1 in the search field to retrieve all products from the database
- C. Use directory traversal syntax in the search field to access server files
- D. Insert admin'- in the search field to attempt bypassing authentication
Answer: B
Explanation:
SQL injection testing commonly involves using tautology-based payloads such as 1 OR 1=1, which force SQL queries to evaluate as true. CEH explains that this confirms improper input sanitization and exposes whether user-supplied fields directly influence database queries. The result often returns all records, indicating successful injection.
NEW QUESTION # 299
DHCP snooping is a great solution to prevent rogue DHCP servers on your network. Which security feature on switchers leverages the DHCP snooping database to help prevent man-in-the-middle attacks?
- A. Layer 2 Attack Prevention Protocol (LAPP)
- B. Port security
- C. Spanning tree
- D. Dynamic ARP Inspection (DAI)
Answer: D
Explanation:
Dynamic ARP inspection (DAI) protects switching devices against Address Resolution Protocol (ARP) packet spoofing (also known as ARP poisoning or ARP cache poisoning).
DAI inspects ARPs on the LAN and uses the information in the DHCP snooping database on the switch to validate ARP packets and to protect against ARP spoofing. ARP requests and replies are compared against entries in the DHCP snooping database, and filtering decisions are made based on the results of those comparisons. When an attacker tries to use a forged ARP packet to spoof an address, the switch compares the address with entries in the database. If the media access control (MAC) address or IP address in the ARP packet does not match a valid entry in the DHCP snooping database, the packet is dropped.
NEW QUESTION # 300
John, a security analyst working for an organization, found a critical vulnerability on the organization's LAN that allows him to view financial and personal information about the rest of the employees. Before reporting the vulnerability, he examines the information shown by the vulnerability for two days without disclosing any information to third parties or other internal employees. He does so out of curiosity about the other employees and may take advantage of this information later.
What would John be considered as?
- A. White hat
- B. Black hat
- C. Gray hat
- D. Cybercriminal
Answer: C
Explanation:
In CEH v13 Module 01: Introduction to Ethical Hacking, Gray Hat hackers are described as those who operate between ethical and unethical lines:
Gray Hat Characteristics:
Discover vulnerabilities without permission.
May explore or exploit them without malicious intent, but also without authorization.
May or may not disclose them after exploration.
Not fully black hat (malicious), nor white hat (authorized and ethical).
In this case, John explored sensitive employee data without authorization, even though he worked for the organization. That behavior places him in the gray hat category.
Option Clarification:
A). Cybercriminal: Generally linked to criminal activities for gain.
B). Black hat: Unauthorized access with malicious or financial intent.
C). White hat: Authorized ethical hackers.
D). Gray hat: Correct - Unauthorized, curious access without immediate harm.

NEW QUESTION # 301
You are Sameer Das, an ethical hacker hired by a national utilities provider to assess the resilience of its power grid infrastructure. During your red team operation, you conduct a phishing campaign targeting field engineers and successfully gain access to the internal OT network. From there, you identify unsecured access to the substation's programmable controllers and replace one of the system's firmware components with a custom payload. This payload silently processes your commands while maintaining access across reboots.
Based on this action, which type of IoT OT threat are you simulating?
- A. Exploit kits
- B. Remote access using backdoor
- C. Forged malicious device
- D. Firmware update attack
Answer: D
Explanation:
The described activity most directly matches a firmware update attack. In CEH coverage of IoT and OT threats, firmware represents the low-level code that runs on embedded devices and industrial controllers, and compromising it is one of the most impactful persistence methods because it survives reboots and often persists through normal configuration resets. The scenario states that Sameer "replaces one of the system's firmware components with a custom payload" and that the payload "maintains access across reboots." Those are signature characteristics of a firmware-level compromise, typically achieved through insecure firmware update mechanisms, weak signing or verification controls, exposed update interfaces, or inadequate access controls on management ports.
A firmware update attack can occur when devices accept unsigned firmware, use weak integrity checks, allow downgrade to vulnerable versions, or expose update services without strong authentication. Once malicious firmware is installed, it can covertly execute commands, manipulate device behavior, hide its presence from higher-level monitoring, and create a durable foothold in OT environments where patching and reimaging are difficult. CEH emphasizes that OT devices such as programmable controllers and substation automation equipment are especially sensitive because firmware tampering can affect availability and safety, not just confidentiality.
Remote access using a backdoor is a broader concept and could be the payload's function, but the primary technique here is achieving persistence by modifying firmware. Forged malicious device refers to introducing rogue hardware, and exploit kits are typically used for automated exploitation on endpoints, not controller firmware replacement.
NEW QUESTION # 302
When configuring wireless on his home router, Javik disables SSID broadcast. He leaves authentication
"open" but sets the SSID to a 32-character string of random letters and numbers.
What is an accurate assessment of this scenario from a security perspective?
- A. Javik's router is still vulnerable to wireless hacking attempts because the SSID broadcast setting can be enabled using a specially crafted packet sent to the hardware address of the access point.
- B. Disabling SSID broadcast prevents 802.11 beacons from being transmitted from the access point, resulting in a valid setup leveraging "security through obscurity".
- C. It is still possible for a hacker to connect to the network after sniffing the SSID from a successful wireless association.
- D. Since the SSID is required in order to connect, the 32-character string is sufficient to prevent brute- force attacks.
Answer: C
Explanation:
In CEH v13 Module 11: Hacking Wireless Networks, it is explained that disabling SSID broadcast only hides the SSID from casual scanning, not from determined attackers.
When a legitimate client connects to a hidden SSID, the SSID is included in the probe request and association packets, which can be easily sniffed using tools like Wireshark or Kismet.
Leaving authentication open adds no real protection.
Attackers can still capture traffic and use it to determine the SSID and connect to the access point.

NEW QUESTION # 303
You are Ethan Brooks, an ethical hacker at Vanguard Security Solutions, hired to perform a wireless penetration test for Pacific Logistics, a shipping company in Seattle, Washington. Your task is to identify all Wi-Fi networks in range without alerting the network administrators. Using a laptop with a Wi-Fi card, you monitor radio channels to detect access points and their BSSIDs without sending any probe requests or injecting data packets.
Based on the described method, which Wi-Fi discovery technique are you employing?
- A. Passive Footprinting
- B. Active Footprinting
- C. Network Discovery Software
- D. Wash Command
Answer: A
Explanation:
The scenario describes a wireless discovery method where the tester only listens to the airwaves and does not transmit probe requests or inject frames. In CEH terms, this is passive reconnaissance, commonly referred to as passive footprinting in the wireless context. Passive footprinting relies on capturing and analyzing existing
802.11 management traffic such as beacon frames (periodically broadcast by access points) and probe responses sent to other clients, allowing the tester to identify SSIDs, BSSIDs (MAC addresses of access points), channel numbers, supported data rates, and sometimes security capabilities, all without generating traffic that could alert administrators or trigger wireless intrusion detection systems.
Active footprinting, by contrast, involves transmitting frames-most notably probe requests-to solicit probe responses from access points, which increases detectability. The question explicitly says Ethan does not send probe requests and does not inject data packets, which rules out active methods. "Network Discovery Software" is too generic; tools can be used for either passive or active discovery, but the technique in use is defined by behavior on the wireless medium, not the presence of software. "Wash" is a specific tool/command associated with enumerating WPS-enabled access points; while it can be used during reconnaissance, the question is testing the broader technique rather than a specific utility, and the defining characteristic here is silent listening.
CEH defensive guidance notes that passive discovery is stealthier because it leverages normal beaconing behavior. Organizations mitigate reconnaissance by using wireless monitoring, rogue AP detection, strong encryption configurations, disabling unnecessary broadcasts where feasible, and maintaining continuous wireless security assessments.
NEW QUESTION # 304
Which Nmap switch helps evade IDS or firewalls?
- A. -n/-R
- B. -0N/-0X/-0G
- C. -D
- D. -T
Answer: C
Explanation:
In CEH v13 Module 03: Scanning Networks, Nmap's evasion techniques are discussed for bypassing or confusing Intrusion Detection Systems (IDS) and firewalls.
The -D option in Nmap is used to enable decoy scanning. It inserts false IP addresses in the scan to obfuscate the true origin of the scan.
This technique helps in masking the attacker's IP and can confuse IDS logs.
Option Clarification:
A). -n/-R: Disables DNS resolution (-n) or uses reverse DNS (-R), does not evade detection.
B). -0N/-0X/-0G: Output formats (normal, XML, grepable), not related to evasion.
C). -T: Controls timing (e.g., -T0 is stealthy, -T5 is aggressive), but not explicitly for IDS evasion.
D). -D: Correct. Used for IDS/firewall evasion by using decoy IPs.

NEW QUESTION # 306
Chandler works as a pen-tester in an IT firm in New York. As part of detecting viruses in the systems, he uses a detection method where the antivirus executes the malicious code on a virtual machine to simulate CPU and memory activities.
Which type of virus detection method did Chandler use in this context?
- A. Scanning
- B. Code Emulation
- C. Heuristic Analysis
- D. Integrity checking
Answer: B
Explanation:
In CEH v13 Module 06: Malware Threats, code emulation is defined as a technique used by modern antivirus software where a virtual CPU and memory are created to safely execute and analyze malware in a sandboxed environment.
This allows the detection engine to observe runtime behavior of suspicious code without risking the actual system.
It's more effective than signature-based detection for catching polymorphic and obfuscated malware.

Which tool is best for sniffing plaintext HTTP traffic?
- A. Nessus
- B. Netcat
- C. Wireshark
- D. Nmap
Answer: C
Explanation:
Wireshark is the primary packet-sniffing tool covered in CEH v13 Network Sniffing. It captures and analyzes live traffic, allowing analysts to view plaintext HTTP packets.
Nessus is a vulnerability scanner, Nmap is for scanning, Netcat is a networking utility. None provide protocol- level inspection like Wireshark.
Thus, Option D is correct.
NEW QUESTION # 309
While assessing a web server, a tester sends malformed HTTP requests and compares responses to identify the server type and version. What technique is being employed?
- A. Conducting session fixation using malformed cookie headers
- B. Fingerprinting server identity using banner-grabbing techniques
- C. Sending phishing emails to extract web server login credentials
- D. Injecting scripts into headers for persistent XSS attacks
Answer: B
Explanation:
CEH v13 explains that fingerprinting is a core reconnaissance technique used to identify software versions, server types, and configurations by analyzing how systems respond to crafted or abnormal input. When testers send malformed HTTP verbs, unusual headers, or atypical URI structures, the server's specific response codes, banners, and error messages reveal distinctive behavioral patterns. These patterns allow tools like
httprint, Nmap NSE scripts, and custom probes to match the responses to known server profiles. This technique is part of active reconnaissance, enabling attackers to determine vulnerabilities associated with specific versions. Phishing (Option B) is unrelated to protocol analysis. Session fixation (Option C) manipulates session identifiers, not HTTP response patterns. Persistent XSS (Option D) relies on web application vulnerabilities, not server fingerprinting. Thus, the tester is performing HTTP-based server fingerprinting.
NEW QUESTION # 310
