NEW QUESTION # 31
A penetration tester is conducting an assessment against a group of publicly available web servers and notices a number of TCP resets returning from one of the web servers. Which of the following is MOST likely causing the TCP resets to occur during the assessment?
- A. The local antivirus on the web server Is rejecting the connection.
- B. The web server is behind a load balancer.
- C. The web server is redirecting the requests.
- D. The web server is using a WAF.
Answer: D
Explanation:
A Web Application Firewall (WAF) is designed to monitor, filter or block traffic to a web application. A WAF will monitor incoming and outgoing traffic from a web application and is often used to protect web servers from attacks such as SQL Injection, Cross-Site Scripting (XSS), and other forms of attacks. If a WAF detects an attack, it will often reset the TCP connection, causing the connection to be terminated. As a result, a penetration tester may see TCP resets when a WAF is present. Therefore, the most likely reason for the TCP resets returning from the web server is that the web server is using a WAF.
NEW QUESTION # 32
A penetration tester needs to collect information over the network for further steps in an internal assessment. Which of the following would most likely accomplish this goal?
- A. crackmapexec smb 192.168.1.0/24
- B. ntlmrelayx.py -t 192.168.1.0/24 -1 1234
- C. nc -tulpn 1234 192.168.1.2
- D. responder.py -I eth0 -wP
Answer: D
Explanation:
To collect information over the network, especially during an internal assessment, tools that can capture and analyze network traffic are essential. Responder is specifically designed for this purpose, and it can capture NTLM hashes and other credentials by poisoning various network protocols. Here's a breakdown of the options:
Option A: ntlmrelayx.py -t 192.168.1.0/24 -1 1234
ntlmrelayx.py is used for relaying NTLM authentication but not for broad network information collection.
Option B: nc -tulpn 1234 192.168.1.2
Netcat (nc) is a network utility for reading from and writing to network connections using TCP or UDP but is not specifically designed for comprehensive information collection over a network.
Option C: responder.py -I eth0 -wP
Responder is a tool for LLMNR, NBT-NS, and MDNS poisoning. The -I eth0 option specifies the network interface, and -wP enables WPAD rogue server which is effective for capturing network credentials and other information.
Option D: crackmapexec smb 192.168.1.0/24
CrackMapExec is useful for SMB-related enumeration and attacks but not specifically for broad network information collection.
Reference from Pentest:
Anubis HTB: Highlights the use of Responder to capture network credentials and hashes during internal assessments.
Horizontall HTB: Demonstrates the effectiveness of Responder in capturing and analyzing network traffic for further exploitation.
NEW QUESTION # 33
Which of the following is a term used to describe a situation in which a penetration tester bypasses physical access controls and gains access to a facility by entering at the same time as an employee?
- A. Tailgating
- B. Shoulder surfing
- C. Badge cloning
- D. Site survey
Answer: A
Explanation:
Understanding Tailgating:
Definition: Tailgating occurs when an unauthorized individual follows an authorized individual into a secure area without the need for the latter to provide credentials.
Risk: Bypasses physical access controls and can lead to unauthorized access to sensitive areas.
Methods to Prevent Tailgating:
Security Awareness: Train employees to be aware of tailgating risks and to challenge unknown individuals.
Physical Controls: Install turnstiles, mantraps, or security doors that only allow one person to enter at a time.
Monitoring: Use CCTV cameras to monitor entrances and exits.
Examples in Penetration Testing:
During a physical security assessment, a penetration tester might follow an employee into a secure area to test the effectiveness of physical security measures.
Tailgating is a common social engineering tactic used to gain unauthorized physical access.
Reference from Pentesting Literature:
Tailgating is discussed in penetration testing methodologies as a critical aspect of physical security assessments.
HTB write-ups occasionally cover scenarios where physical access was gained through tailgating.

NEW QUESTION # 34
A company obtained permission for a vulnerability scan from its cloud service provider and now wants to test the security of its hosted data.
Which of the following should the tester verify FIRST to assess this risk?
- A. Whether the cloud applications were developed using a secure SDLC
- B. Whether sensitive client data is publicly accessible
- C. Whether the client's employees are trained properly to use the platform
- D. Whether the connection between the cloud and the client is secure
Answer: B
NEW QUESTION # 35
A company recently moved its software development architecture from VMs to containers. The company has asked a penetration tester to determine if the new containers are configured correctly against a DDoS attack.
Which of the following should a tester perform first?
- A. .Scan the containers for open ports.
- B. Perform a vulnerability check against the hypervisor.
- C. Determine if security tokens are easily available.
- D. Test the strength of the encryption settings.
Answer: A
Explanation:
The first step that a tester should perform to determine if the new containers are configured correctly against a DDoS attack is to scan the containers for open ports. Open ports are entry points for network communication and can expose services or applications that may be vulnerable to DDoS attacks. Scanning the containers for open ports can help the tester identify which services or applications are running on the containers, and which ones may need to be secured or disabled to prevent DDoS attacks. Scanning the containers for open ports can also help the tester discover any unauthorized or malicious services or applications that may have been installed on the containers by previous attackers or compromised containers. Scanning the containers for open ports can be done by using tools such as Nmap, which can perform network scanning and enumeration by sending packets to hosts and analyzing their responses1. The other options are not the first steps that a tester should perform to determine if the new containers are configured correctly against a DDoS attack. Testing the strength of the encryption settings is not relevant to DDoS attacks, as encryption does not prevent or mitigate DDoS attacks, but rather protects data confidentiality and integrity. Determining if security tokens are easily available is not relevant to DDoS attacks, as security tokens are used for authentication and authorization, not for preventing or mitigating DDoS attacks. Performing a vulnerability check against the hypervisor is not relevant to DDoS attacks, as the hypervisor is not directly exposed to network traffic, but rather manages the virtual machines or containers that run on it.

Which of the following commands was executed by the tester?
- A. nmap-sU-pU:517-Pn-n-script=supermicro-ipmi-config<target>
- B. nmap-sU-pU:37 -Pn -n -script=icap-info <target>
- C. nmap-sU-pU:161-Pn-n-script=voldemort-info <target>
- D. nmap-sU-pU:123-Pn-n-script=ntp-monlist <target>
Answer: D
Explanation:
The output provided indicates the use of the NTP protocol (Network Time Protocol) for querying a target system. The reference to "Public Clients" and the specific IP addresses listed, along with the mention of
"Other Associations" and the use of NTP version 2, points towards the execution of an NTP monlist request.
The monlist feature in NTP servers can be used to obtain a list of the last 600 hosts that have interacted with the NTP server. The command nmap -sU -pU:123 -Pn -n -script=ntp-monlist <target> specifically targets NTP servers on UDP port 123 to retrieve this information, making it the correct choice based on the output shown.

A penetration tester wants to find hidden information in documents available on the web at a particular domain. Which of the following should the penetration tester use?
- A. CentralOps
- B. Responder
- C. FOCA
- D. Netcraft
Answer: C
Explanation:
https://kalilinuxtutorials.com/foca-metadata-hidden-documents/
FOCA (Fingerprinting Organizations with Collected Archives) is a tool that is used to find hidden information in documents available on the web. It can be used to extract metadata from documents such as PDF, Microsoft Office, OpenOffice, and others. The metadata can include information such as the author, creation date, and software used to create the document. FOCA can also extract information from the document's properties such as the title, keywords, and comments. This tool can also identify specific keywords and patterns in the document and can be useful in identifying sensitive information that may have been inadvertently left in the document.
NEW QUESTION # 40
ion tester is attempting to get more people from a target company to download and run an executable. Which of the following would be the.. :tive way for the tester to achieve this objective?
- A. Saving the file in a common folder with a name that encourages people to click it
- B. Sending a pretext email from the IT department before sending the download instructions later
- C. Dropping USB flash drives around the company campus with the file on it
- D. Attaching the file in a phishing SMS that warns users to execute the file or they will be locked out of their accounts
Answer: B
Explanation:
The most effective way for the tester to achieve this objective is to send a pretext email from the IT department before sending the download instructions later. A pretext email is an email that uses deception or impersonation to trick users into believing that it is from a legitimate source or authority, such as the IT department. A pretext email can be used to establish trust or rapport with the users, and then persuade them to perform an action or provide information that benefits the attacker. In this case, the tester can send a pretext email from the IT department that informs users about an important update or maintenance task that requires them to download and run an executable file later. The tester can then send another email with the download instructions and attach or link to the malicious executable file. The users may be more likely to follow these instructions if they have received a prior email from the IT department that prepared them for this action. The other options are not as effective ways for the tester to achieve this objective. Dropping USB flash drives around the company campus with the file on it may not reach many users, as they may not find or pick up the USB flash drives, or they may be suspicious of their origin or content.
NEW QUESTION # 41
Which of the following BEST explains why a penetration tester cannot scan a server that was previously scanned successfully?
- A. The server is unreachable.
- B. The IP address is on the blocklist.
- C. The IP address is wrong.
- D. The IP address is on the allow list.
Answer: B
Explanation:
The most likely explanation for why a penetration tester cannot scan a server that was previously scanned successfully is that the IP address is on the blocklist. Blocklists are used to prevent malicious actors from scanning servers, and if the IP address of the server is on the blocklist, the scanning process will be blocked.

Hunter.io is specifically designed to collect and validate email addresses for a given domain, making it the correct answer.
NEW QUESTION # 43
A red-team tester has been contracted to emulate the threat posed by a malicious insider on a company's network, with the constrained objective of gaining access to sensitive personnel files. During the assessment, the red-team tester identifies an artifact indicating possible prior compromise within the target environment.
Which of the following actions should the tester take?
- A. Halt the assessment and follow the reporting procedures as outlined in the contract.
- B. Perform forensic analysis to isolate the means of compromise and determine attribution.
- C. Create a detailed document of findings before continuing with the assessment.
- D. Incorporate the newly identified method of compromise into the red team's approach.
Answer: A
Explanation:
Halting the assessment and following the reporting procedures as outlined in the contract is the best action to take after identifying that an application being tested has already been compromised with malware. This is because continuing the assessment might interfere with an ongoing investigation or compromise evidence collection. The reporting procedures are part of the contract that specifies how to handle any critical issues or incidents during the penetration testing engagement. They should include details such as who to contact, what information to provide, and what steps to follow.
NEW QUESTION # 44
A penetration tester noticed that an employee was using a wireless headset with a smartphone. Which of the following methods would be best to use to intercept the communications?
- A. Bluejacking
- B. Zero-day attack
- C. Smurf attack
- D. Multiplexing
Answer: A
Explanation:
To intercept the communications between an employee's wireless headset and smartphone, the penetration tester would likely use "Bluejacking" (B). Bluejacking involves sending unsolicited messages to Bluetooth-enabled devices, but in the context of penetration testing and security, it can also encompass techniques for intercepting or hijacking Bluetooth connections. This could allow the tester to eavesdrop on communications or even take control of the headset.
NEW QUESTION # 45
A penetration tester is taking screen captures of hashes obtained from a domain controller. Which of the following best explains why the penetration tester should immediately obscure portions of the images before saving?
- A. To prevent analysis based on the type of hash
- B. To maintain confidentiality of data/information
- C. To avoid disclosure of how the hashes were obtained
- D. To make the hashes appear shorter and easier to crack
Answer: B
Explanation:
When a penetration tester captures screen images that include hashes from a domain controller, obscuring parts of these images before saving is crucial to maintain the confidentiality of sensitive data. Hashes can be considered sensitive information as they represent a form of digital identity for users within an organization.
Revealing these hashes in full could lead to unauthorized access if the hashes were to be cracked or otherwise misused by malicious actors. By partially obscuring the images, the penetration tester ensures that the data remains confidential and reduces the risk of compromising user accounts and the integrity of the organization's security posture.
