NEW QUESTION # 186
You went to great lengths to install all the necessary technologies to prevent hacking attacks, such as expensive firewalls, antivirus software, anti-spam systems and intrusion detection/prevention tools in your company's network. You have configured the most secure policies and tightened every device on your network. You are confident that hackers will never be able to gain access to your network with complex security system in place.
Your peer, Peter Smith who works at the same department disagrees with you.
He says even the best network security technologies cannot prevent hackers gaining access to the network because of presence of "weakest link" in the security chain.
What is Peter Smith talking about?
- A. Continuous Spam e-mails cannot be blocked by your security system since spammers use different techniques to bypass the filters in your gateway
- B. "zero-day" exploits are the weakest link in the security chain since the IDS will not be able to detect these attacks
- C. Untrained staff or ignorant computer users who inadvertently become the weakest link in your security chain
- D. "Polymorphic viruses" are the weakest link in the security chain since the Anti-Virus scanners will not be able to detect these attacks

NEW QUESTION # 188
You are an ethical hacker contracted to conduct a security audit for a company. During the audit, you discover that the company's wireless network is using WEP encryption. You understand the vulnerabilities associated with WEP and plan to recommend a more secure encryption method. Which of the following would you recommend as a Suitable replacement to enhance the security of the company's wireless network?
- A. WPA2-PSK with AES encryption
- B. SSID broadcast disabling
- C. Open System authentication
- D. MAC address filtering
Answer: A
Explanation:
WEP encryption is an outdated and insecure method of protecting wireless networks from unauthorized access and eavesdropping. WEP uses a static key that can be easily cracked by various tools and techniques, such as capturing the initialization vectors, brute-forcing the key, or exploiting the weak key scheduling algorithm1.
Therefore, you should recommend a more secure encryption method to enhance the security of the company's wireless network.
One of the most suitable replacements for WEP encryption is WPA2-PSK with AES encryption. WPA2 stands for Wi-Fi Protected Access 2, which is a security standard that improves upon the previous WPA standard.
WPA2 uses a robust encryption algorithm called AES, which stands for Advanced Encryption Standard. AES is a block cipher that uses a 128-bit key and is considered to be very secure and resistant to attacks2.
WPA2-PSK stands for WPA2 Pre-Shared Key, which is a mode of WPA2 that uses a passphrase or a password to generate the encryption key. The passphrase or password must be entered by the users who want to connect to the wireless network. The key is then derived from the passphrase or password using a function called PBKDF2, which stands for Password-Based Key Derivation Function 2. PBKDF2 adds a salt and a number of iterations to the passphrase or password to make it harder to crack3.
WPA2-PSK with AES encryption offers several advantages over WEP encryption, such as:
* It uses a dynamic key that changes with each session, instead of a static key that remains the same.
* It uses a stronger encryption algorithm that is more difficult to break, instead of a weaker encryption algorithm that is more vulnerable to attacks.
* It uses a longer key that provides more security, instead of a shorter key that provides less security.
* It uses a more secure key derivation function that adds complexity and randomness, instead of a simple key generation function that is predictable and flawed.
Therefore, you should recommend WPA2-PSK with AES encryption as a suitable replacement to enhance the security of the company's wireless network.

NEW QUESTION # 189
Harry. a professional hacker, targets the IT infrastructure of an organization. After preparing for the attack, he attempts to enter the target network using techniques such as sending spear-phishing emails and exploiting vulnerabilities on publicly available servers. Using these techniques, he successfully deployed malware on the target system to establish an outbound connection. What is the APT lifecycle phase that Harry is currently executing?
- A. Persistence
- B. Cleanup
- C. initial intrusion
- D. Preparation
Answer: D
Explanation:
After the attacker completes preparations, subsequent step is an effort to realize an edge within the target's environment. a particularly common entry tactic is that the use of spearphishing emails containing an internet link or attachment. Email links usually cause sites where the target's browser and related software are subjected to varied exploit techniques or where the APT actors plan to social engineer information from the victim which will be used later. If a successful exploit takes place, it installs an initial malware payload on the victim's computer. Figure 2 illustrates an example of a spearphishing email that contains an attachment. Attachments are usually executable malware, a zipper or other archive containing malware, or a malicious Office or Adobe PDF (Portable Document Format) document that exploits vulnerabilities within the victim's applications to ultimately execute malware on the victim's computer. Once the user has opened a malicious file using vulnerable software, malware is executing on the target system. These phishing emails are often very convincing and difficult to differentiate from legitimate email messages. Tactics to extend their believability include modifying legitimate documents from or associated with the organization. Documents are sometimes stolen from the organization or their collaborators during previous exploitation operations. Actors modify the documents by adding exploits and malicious code then send them to the victims. Phishing emails are commonly sent through previously compromised email servers, email accounts at organizations associated with the target or public email services. Emails also can be sent through mail relays with modified email headers to form the messages appear to possess originated from legitimate sources. Exploitation of vulnerabilities on public-facing servers is another favorite technique of some APT groups. Though this will be accomplished using exploits for known vulnerabilities, 0-days are often developed or purchased to be used in intrusions as required .
NEW QUESTION # 190
A certified ethical hacker is conducting a Whois footprinting activity on a specific domain. The individual is leveraging various tools such as Batch IP Converter and Whols Analyzer Pro to retrieve vital details but is unable to gather complete Whois information from the registrar for a particular set of data. As the hacker, what might be the probable data model being utilized by the domain's registrar for storing and looking up Who is information?
- A. Thick Whois model with a malfunctioning server
- B. Thin Whois model with a malfunctioning server
- C. Thin Whois model working correctly
- D. Thick Whois model working correctly
Answer: C
Explanation:
A thin Whois model is a type of data model that is used by some domain registrars for storing and looking up Whois information. In a thin Whois model, the registrar only stores the basic information about the domain, such as the domain name, the registrar name, the name servers, and the registration and expiration dates. The rest of the information, such as the contact details of the domain owner, the administrative contact, and the technical contact, is stored by the registry that manages the top-level domain (TLD) of the domain. For example, the registry for .com and .net domains is Verisign, and the registry for .org domains is Public Interest Registry. When a Whois lookup is performed on a domain that uses a thin Whois model, the registrar's Whois server only returns the basic information and refers the query to the registry's Whois server for the complete information1.
As a hacker, if you are unable to gather complete Whois information from the registrar for a particular set of data, it might be because the domain's registrar is using a thin Whois model and the registry's Whois server is not responding or providing the information. This could be due to various reasons, such as network issues, server errors, rate limits, privacy policies, or legal restrictions. Therefore, the probable data model being utilized by the domain's registrar for storing and looking up Whois information is a thin Whois model working correctly.

NEW QUESTION # 191
Cross-site request forgery involves:
- A. A browser making a request to a server without the user's knowledge
- B. A request sent by a malicious user from a browser to a server
- C. A server making a request to another server without the user's knowledge
- D. Modification of a request by a proxy between client and server
Answer: A
Explanation:
https://owasp.org/www-community/attacks/csrf
Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. With a little help of social engineering (such as sending a link via email or chat), an attacker may trick the users of a web application into executing actions of the attacker's choosing. If the victim is a normal user, a successful CSRF attack can force the user to perform state changing requests like transferring funds, changing their email address, and so forth. If the victim is an administrative account, CSRF can compromise the entire web application.
CSRF is an attack that tricks the victim into submitting a malicious request. It inherits the identity and privileges of the victim to perform an undesired function on the victim's behalf. For most sites, browser requests automatically include any credentials associated with the site, such as the user's session cookie, IP address, Windows domain credentials, and so forth. Therefore, if the user is currently authenticated to the site, the site will have no way to distinguish between the forged request sent by the victim and a legitimate request sent by the victim.
CSRF attacks target functionality that causes a state change on the server, such as changing the victim's email address or password, or purchasing something. Forcing the victim to retrieve data doesn't benefit an attacker because the attacker doesn't receive the response, the victim does. As such, CSRF attacks target state-changing requests.
It's sometimes possible to store the CSRF attack on the vulnerable site itself. Such vulnerabilities are called
"stored CSRF flaws". This can be accomplished by simply storing an IMG or IFRAME tag in a field that accepts HTML, or by a more complex cross-site scripting attack. If the attack can store a CSRF attack in the site, the severity of the attack is amplified. In particular, the likelihood is increased because the victim is more likely to view the page containing the attack than some random page on the Internet. The likelihood is also increased because the victim is sure to be authenticated to the site already.

NEW QUESTION # 193
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?
- A. 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
- B. 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
- 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
- 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
Answer: A
Explanation:
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 .

Heather's company has decided to use a new customer relationship management tool. After performing the appropriate research, they decided to purchase a subscription to a cloud-hosted solution. The only administrative task that Heather will need to perform is the management of user accounts. The provider will take care of the hardware, operating system, and software administration including patching and monitoring. Which of the following is this type of solution?
- A. SaaS
- B. CaaS
- C. PasS
- D. IaaS
Answer: A
Explanation:
Software as a service (SaaS) allows users to attach to and use cloud-based apps over the web. Common examples ar email, calendaring and workplace tool (such as Microsoft workplace 365).
SaaS provides a whole software solution that you get on a pay-as-you-go basis from a cloud service provider. You rent the use of an app for your organisation and your users connect with it over the web, typically with an internet browser. All of the underlying infrastructure, middleware, app software system and app knowledge ar located within the service provider's knowledge center. The service provider manages the hardware and software system and with the appropriate service agreement, can make sure the availability and also the security of the app and your data as well. SaaS allows your organisation to induce quickly up and running with an app at token upfront cost.
Common SaaS scenarios
This tool having used a web-based email service like Outlook, Hotmail or Yahoo! Mail, then you have got already used a form of SaaS. With these services, you log into your account over the web, typically from an internet browser. the e-mail software system is found on the service provider's network and your messages ar hold on there moreover. you can access your email and hold on messages from an internet browser on any laptop or Internet-connected device.
The previous examples are free services for personal use. For organisational use, you can rent productivity apps, like email, collaboration and calendaring; and sophisticated business applications like client relationship management (CRM), enterprise resource coming up with (ERP) and document management. You buy the use of those apps by subscription or per the level of use.
Advantages of SaaS
Gain access to stylish applications. to supply SaaS apps to users, you don't ought to purchase, install, update or maintain any hardware, middleware or software system. SaaS makes even sophisticated enterprise applications, like ERP and CRM, affordable for organisations that lack the resources to shop for, deploy and manage the specified infrastructure and software system themselves.
Pay just for what you utilize. you furthermore may economize because the SaaS service automatically scales up and down per the level of usage.
Use free shopper software system. Users will run most SaaS apps directly from their web browser without needing to transfer and install any software system, though some apps need plugins. this suggests that you simply don't ought to purchase and install special software system for your users.
Mobilise your hands simply. SaaS makes it simple to "mobilise" your hands as a result of users will access SaaS apps and knowledge from any Internet-connected laptop or mobile device. You don't ought to worry concerning developing apps to run on differing types of computers and devices as a result of the service supplier has already done therefore. additionally, you don't ought to bring special experience aboard to manage the safety problems inherent in mobile computing. A fastidiously chosen service supplier can make sure the security of your knowledge, no matter the sort of device intense it.
Access app knowledge from anyplace. With knowledge hold on within the cloud, users will access their info from any Internet-connected laptop or mobile device. And once app knowledge is hold on within the cloud, no knowledge is lost if a user's laptop or device fails.
