質問 # 18
An ethical hacker is hired to conduct a comprehensive network scan of a large organization that strongly suspects potential intrusions into their internal systems. The hacker decides to employ a combination of scanning tools to obtain a detailed understanding of the network. Which sequence of actions would provide the most comprehensive information about the network's status?
正解:D
解説:
The sequence of actions that would provide the most comprehensive information about the network's status is to use Hping3 for an ICMP ping scan on the entire subnet, then use Nmap for a SYN scan on identified active hosts, and finally use Metasploit to exploit identified vulnerabilities. This sequence of actions works as follows:
* Use Hping3 for an ICMP ping scan on the entire subnet: This action is used to discover the active hosts on the network by sending ICMP echo request packets to each possible IP address on the subnet and waiting for ICMP echo reply packets from the hosts. Hping3 is a command-line tool that can craft and send custom packets, such as TCP, UDP, or ICMP, and analyze the responses. By using Hping3 for an ICMP ping scan, the hacker can quickly and efficiently identify the live hosts on the network, as well as their response times and packet loss rates12.
* Use Nmap for a SYN scan on identified active hosts: This action is used to scan the open ports and services on the active hosts by sending TCP SYN packets to a range of ports and analyzing the TCP responses. Nmap is a popular and powerful tool that can perform various types of network scans, such as port scanning, service detection, OS detection, and vulnerability scanning. By using Nmap for a SYN scan, the hacker can determine the state of the ports on the active hosts, such as open, closed, filtered, or unfiltered, as well as the services and protocols running on them. A SYN scan is also known as a stealth scan, as it does not complete the TCP three-way handshake and thus avoids logging on the target system34.
* Use Metasploit to exploit identified vulnerabilities: This action is used to exploit the vulnerabilities on the active hosts by using pre-built or custom modules that leverage the open ports and services.
Metasploit is a framework that contains a collection of tools and modules for penetration testing and exploitation. By using Metasploit, the hacker can launch various attacks on the active hosts, such as remote code execution, privilege escalation, or backdoor installation, and gain access to the target system or data. Metasploit can also be used to perform post-exploitation tasks, such as gathering information, maintaining persistence, or pivoting to other systems .
The other options are not as comprehensive as option B for the following reasons:
* A. Initiate with Nmap for a ping sweep, then use Metasploit to scan for open ports and services, and finally use Hping3 to perform remote OS fingerprinting: This option is not optimal because it does not use the tools in the most efficient and effective way. Nmap can perform a ping sweep, but it is slower and less flexible than Hping3, which can craft and send custom packets. Metasploit can scan for open ports and services, but it is more suitable for exploitation than scanning, and it relies on Nmap for port scanning anyway. Hping3 can perform remote OS fingerprinting, but it is less accurate and reliable than Nmap, which can use various techniques and probes to determine the OS type and version13 .
* C. Start with Hping3 for a UDP scan on random ports, then use Nmap for a version detection scan, and finally use Metasploit to exploit detected vulnerabilities: This option is not effective because it does not use the best scanning methods and techniques. Hping3 can perform a UDP scan, but it is slower and less reliable than a TCP scan, as UDP is a connectionless protocol that does not always generate responses. Scanning random ports is also inefficient and incomplete, as it may miss important ports or services. Nmap can perform a version detection scan, but it is more useful to perform a port scan first, as it can narrow down the scope and speed up the scan. Metasploit can exploit detected vulnerabilities, but it is not clear how the hacker can identify the vulnerabilities without performing a vulnerability scan first13 .
* D. Begin with NetScanTools Pro for a general network scan, then use Nmap for OS detection and version detection, and finally perform an SYN flooding with Hping3: This option is not comprehensive because it does not cover all the aspects and objectives of a network scan. NetScanTools Pro is a graphical tool that can perform various network tasks, such as ping, traceroute, DNS lookup, or port scan, but it is less powerful and versatile than Nmap or Hping3, which can perform more advanced and customized scans. Nmap can perform OS detection and version detection, but it is more useful to perform a port scan first, as it can provide more information and insights into the target system. Performing an SYN flooding with Hping3 is not a network scan, but a denial-of-service attack, which can disrupt the network and alert the target system, and it is not an ethical or legal action for a hired hacker13 .

質問 # 19
Which results will be returned with the following Google search query?
site:target.com -site:Marketing.target.com accounting
正解:A
解説:
This Google dork uses advanced operators:
site:target.com - restricts results to pages within the target.com domain
-site:Marketing.target.com - excludes results from the marketing.target.com subdomain accounting - the keyword to be matched So, it returns pages from target.com (excluding the marketing subdomain) that include the word "accounting".
Reference - CEH v13 Official Study Guide:
Module 2: Footprinting and Reconnaissance
Quote:
"Advanced search operators like site:, inurl:, intitle:, and the minus (-) operator help to include or exclude specific domains or pages when gathering public information via Google." Incorrect Options:
A). Opposite logic - this excludes marketing.target.com
B). Too general
C). Incorrect because marketing.target.com is excluded

質問 # 20
Which of the following web vulnerabilities would an attacker be attempting to exploit if they delivered the following input?
正解:D
解説:
In CEH v13 Module 13: Hacking Web Applications, this exact payload is an example of an XXE (XML External Entity) Attack.
XXE Attack:
Exploits the way XML parsers process DOCTYPE declarations.
The payload references a local file (/etc/passwd), allowing local file inclusion.
Can result in sensitive file disclosure, SSRF, or Denial of Service (DoS).
Option Clarification:
A). XXE: Correct - targets vulnerable XML parsers.
B). SQLi: Targets SQL databases with ' OR '1'='1-type injections.
C). IDOR: Insecure Direct Object Reference, not related to XML.
D). XSS: Cross-site scripting; this is XML-based, not JavaScript injection.

質問 # 21
You have successfully logged on to a Linux system. You want to now cover your tracks. Your login attempt may be logged in several files located in /var/log. Which file does NOT belong to this list?
正解:D
解説:
Comprehensive and Detailed Explanation:
The correct file name is /var/log/auth.log (not auth.fesg). "auth.fesg" is a typo or does not exist by default in Linux systems.
Linux login records include:
* /var/log/auth.log - authentication logs
* /var/log/wtmp - records login sessions
* /var/log/btmp - records failed logins
* /var/log/user.log - logs user-level messages (optional)
Therefore, B is not a valid log file.
From CEH v13 Courseware:
* Module 6: System Hacking # Covering Tracks in Linux
Reference:Linux Man Pages - wtmp, btmp, auth.log
