A penetration tester finished a security scan and uncovered numerous vulnerabilities on several hosts.
Based on the targets' EPSS and CVSS scores, which of the following targets is the most likely to get attacked?
- A. Target 4: EPSS Score = 0.4 and CVSS Score = 4.5
- B. Target 1: EPSS Score = 0.6 and CVSS Score = 4
- C. Target 3: EPSS Score = 0.6 and CVSS Score = 1
- D. Target 2: EPSS Score = 0.3 and CVSS Score = 2
Answer: B
Explanation:
* EPSS and CVSS Analysis:
* EPSS (Exploit Prediction Scoring System) indicates the likelihood of exploitation.
* CVSS (Common Vulnerability Scoring System) represents the severity of the vulnerability.
* Rationale:
* Target 1 has the highest EPSS score (0.6) combined with a moderately high CVSS score (4), making it the most likely to be attacked.
* Other options either have lower EPSS or CVSS scores, reducing their likelihood of being exploited.

NEW QUESTION # 115
A penetration tester wants to use multiple TTPs to assess the reactions (alerted, blocked, and others) by the client's current security tools. The threat-modeling team indicates the TTPs in the list might affect their internal systems and servers. Which of the following actions would the tester most likely take?
- A. Use a BAS tool to test multiple TTPs based on the input from the threat-modeling team.
- B. Perform an internal vulnerability assessment with credentials to review the internal attack surface.
- C. Use a generic vulnerability scanner to test the TTPs and review the results with the threat- modeling team.
- D. Perform a full internal penetration test to review all the possible exploits that could affect the systems.
Answer: A
Explanation:
BAS (Breach and Attack Simulation) tools are specifically designed to emulate multiple TTPs (Tactics, Techniques, and Procedures) used by adversaries. These tools can simulate various attack vectors in a controlled manner to test the effectiveness of an organization's security defenses and response mechanisms.
Controlled Testing Environment: BAS tools provide a controlled environment where multiple TTPs can be tested without causing unintended damage to the internal systems and servers. This is critical when the threat-modeling team indicates potential impacts on internal systems.
Comprehensive Coverage: BAS tools are designed to cover a wide range of TTPs, allowing the penetration tester to simulate various attack scenarios. This helps in assessing the reactions (alerted, blocked, and others) by the client's security tools comprehensively. Feedback and Reporting: These tools provide detailed feedback and reporting on the effectiveness of the security measures in place, including which TTPs were detected, blocked, or went unnoticed.
This information is invaluable for the threat-modeling team to understand the current security posture and areas for improvement.
NEW QUESTION # 116
A penetration tester needs to evaluate the order in which the next systems will be selected for testing. Given the following output:
Hostname | IP address | CVSS 2.0 | EPSS
hrdatabase | 192.168.20.55 | 9.9 | 0.50
financesite | 192.168.15.99 | 8.0 | 0.01
legaldatabase | 192.168.10.2 | 8.2 | 0.60
fileserver | 192.168.125.7 | 7.6 | 0.90
Which of the following targets should the tester select next?
- A. hrdatabase
- B. fileserver
- C. legaldatabase
- D. financesite
Answer: B
Explanation:
Given the output, the penetration tester should select the fileserver as the next target for testing, considering both CVSS and EPSS scores.
Explanation:
* CVSS (Common Vulnerability Scoring System):
* Purpose: CVSS provides a numerical score to represent the severity of vulnerabilities, helping to prioritize remediation efforts.
* Higher Scores: Indicate more severe vulnerabilities.
* EPSS (Exploit Prediction Scoring System):
* Purpose: EPSS estimates the likelihood that a vulnerability will be exploited in the wild within the next 30 days.
* Higher Scores: Indicate a higher likelihood of exploitation.
* Evaluation:
* hrdatabase: CVSS = 9.9, EPSS = 0.50
* financesite: CVSS = 8.0, EPSS = 0.01
* legaldatabase: CVSS = 8.2, EPSS = 0.60
* fileserver: CVSS = 7.6, EPSS = 0.90
* The fileserver has the highest EPSS score, indicating a high likelihood of exploitation, despite having a slightly lower CVSS score compared to hrdatabase and legaldatabase.
Pentest References:
* Prioritization: Balancing between severity (CVSS) and exploitability (EPSS) is crucial for effective vulnerability management.
* Risk Assessment: Evaluating both the impact and the likelihood of exploitation helps in making informed decisions about testing priorities.
By selecting the fileserver, which has a high EPSS score, the penetration tester focuses on a target that is more likely to be exploited, thereby addressing the most immediate risk.

NEW QUESTION # 119
Which of the following is the most efficient way to infiltrate a file containing data that could be sensitive?
- A. Use steganography and send the file over FTP
- B. Encrypt and send the file over HTTPS
- C. Compress the file and send it using TFTP
- D. Split the file in tiny pieces and send it over dnscat
Answer: B
Explanation:
When considering efficiency and security for exfiltrating sensitive data, the chosen method must ensure data confidentiality and minimize the risk of detection. Here's an analysis of each option:
Use steganography and send the file over FTP (Option A):
Steganography hides data within other files, such as images. FTP is a protocol for transferring files.
Drawbacks: FTP is not secure as it transmits data in clear text, making it susceptible to interception.
Steganography can add an extra layer of obfuscation, but the use of FTP makes this option insecure.
Compress the file and send it using TFTP (Option B):
TFTP is a simple file transfer protocol that lacks encryption.
Drawbacks: TFTP is inherently insecure because it does not support encryption, making it easy for attackers to intercept the data during transfer.
Split the file in tiny pieces and send it over dnscat (Option C):
dnscat is a tool for tunneling data over DNS.
Drawbacks: While effective at evading detection by using DNS, splitting the file and managing the reassembly adds complexity. Additionally, large data transfers over DNS can raise suspicion.
Encrypt and send the file over HTTPS (Answer: D):
Encrypting the file ensures that its contents are protected during transfer. HTTPS provides a secure, encrypted channel for communication over the internet.
Advantages: HTTPS is widely used and trusted, making it less likely to raise suspicion. Encryption ensures the data remains confidential during transit.
References:
The use of HTTPS for secure data transfer is a standard practice in cybersecurity, providing both encryption and integrity of the data being transmitted.
Conclusion: Encrypting the file and sending it over HTTPS is the most efficient and secure method for exfiltrating sensitive data, ensuring both confidentiality and reducing the risk of detection.

NEW QUESTION # 122
A penetration tester compromises a Windows OS endpoint that is joined to an Active Directory local environment. Which of the following tools should the tester use to manipulate authentication mechanisms to move laterally in the network?
- A. WinPEAS
- B. Rubeus
- C. Impacket
- D. NTLMRelayX
Answer: B
Explanation:
Rubeus is a post-exploitation tool used for Kerberos abuse, including ticket extraction, pass-the-ticket, ticket renewal, and Kerberoasting. It's ideal for lateral movement within Active Directory environments.
WinPEAS is mainly used for local privilege escalation and enumeration.
NTLMRelayX (from Impacket) is useful for relaying NTLM authentication but is not focused on Kerberos.
Impacket is a collection of tools; Rubeus is more targeted for Kerberos attacks.
Reference: PT0-003 Objective 4.2 - Tools and techniques for lateral movement and manipulating authentication in Windows AD environments.
NEW QUESTION # 123
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. Host-based
- B. Unauthenticated
- C. Sidecar
- D. SAST
Answer: B
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 References:
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 # 125
A penetration tester finishes an initial discovery scan for hosts on a /24 customer subnet. The customer states that the production network is composed of Windows servers but no container clusters. The following are the last several lines from the scan log:
Line 1: 112 hosts found... trying ports
Line 2: FOUND 22 with OpenSSH 1.2p2 open on 99 hosts
Line 3: FOUND 161 with UNKNOWN banner open on 110 hosts
Line 4: TCP RST received on ports 21, 3389, 80
Line 5: Scan complete.
Which of the following is the most likely reason for the results?
- A. The wrong subnet was scanned
- B. IPS is blocking the ports
- C. Windows is using WSL
- D. Multiple honeypots were encountered
Answer: D
Explanation:
Seeing services like OpenSSH 1.2p2 open on 99 hosts, and port 161 (SNMP) with unknown banners on 110 hosts suggests a high level of uniformity, which is uncommon in real-world Windows environments. This strongly points to honeypots being present, possibly for detection or deception.
The official CompTIA guide discusses this under scan anomalies:
"Identical responses from a large number of hosts, especially deprecated versions or unchanging banners, could indicate the presence of honeypots or decoy systems." Reference: CompTIA PenTest+ PT0-003 Official Study Guide, Chapter 5
NEW QUESTION # 126
The provision that defines the level of responsibility between the penetration tester and the client for preventing unauthorized disclosure is found in the:
- A. MSA
- B. SOW
- C. NDA
- D. SLA
Answer: C
Explanation:
The provision that defines the level of responsibility between the penetration tester and the client for preventing unauthorized disclosure is found in the NDA, which stands for Non-Disclosure Agreement. The NDA is a legal agreement between two or more parties that outlines confidential material or knowledge that the parties wish to share with one another, but with restrictions on access, use or disclosure of that information. The NDA is commonly used in the context of penetration testing to protect the client's sensitive information that the tester may have access to during the engagement.
The NDA defines the terms of confidentiality and non-disclosure of information related to the engagement, including the responsibilities and obligations of both the tester and the client to ensure that any information exchanged or obtained during the engagement is kept confidential and not disclosed to unauthorized parties.
This is particularly important in penetration testing, as the tester is granted access to the client's network and systems, and may uncover vulnerabilities or sensitive information that should not be disclosed to unauthorized parties.
In summary, the NDA plays a crucial role in defining the level of responsibility between the penetration tester and the client for preventing unauthorized disclosure of confidential information, and is an important legal instrument for protecting the client's sensitive information during a penetration testing engagement.

NEW QUESTION # 129
During a penetration test, a tester captures information about an SPN account. Which of the following attacks requires this information as a prerequisite to proceed?
- A. LSASS dumping
- B. Kerberoasting
- C. Golden Ticket
- D. DCShadow
Answer: B
Explanation:
Kerberoasting is an attack that specifically targets Service Principal Name (SPN) accounts in a Windows Active Directory environment. Here's a detailed explanation:
* Understanding SPN Accounts:
* SPNs are unique identifiers for services in a network that allows Kerberos to authenticate service accounts. These accounts are often associated with services such as SQL Server, IIS, etc.
* Kerberoasting Attack:
* Prerequisite: Knowledge of the SPN account.
* Process: An attacker requests a service ticket for the SPN account using the Kerberos protocol.
The ticket is encrypted with the service account's NTLM hash. The attacker captures this ticket and attempts to crack the hash offline.
* Objective: To obtain the plaintext password of the service account, which can then be used for lateral movement or privilege escalation.
* Comparison with Other Attacks:
* Golden Ticket: Involves forging Kerberos TGTs using the KRBTGT account hash, requiring domain admin credentials.
* DCShadow: Involves manipulating Active Directory data by impersonating a domain controller, typically requiring high privileges.
* LSASS Dumping: Involves extracting credentials from the LSASS process on a Windows machine, often requiring local admin privileges.
Kerberoasting specifically requires the SPN account information to proceed, making it the correct answer.
NEW QUESTION # 130
A penetration tester is conducting an assessment of a web application's login page. The tester needs to determine whether there are any hidden form fields of interest. Which of the following is the most effective technique?
- A. HTML scraping
- B. XSS
- C. SQL injection
- D. On-path attack
Answer: A
Explanation:
Hidden form fields in web applications can store user roles, session tokens, and security parameters that attackers may exploit.
HTML scraping (Option D):
Involves analyzing HTML source code to find hidden fields like:
<input type="hidden" name="admin_access" value="true">
Attackers use tools like Burp Suite, ZAP, or browser developer tools (Ctrl+U or Inspect Element) to locate hidden fields.
Reference: CompTIA PenTest+ PT0-003 Official Study Guide - "Web Application Testing and Form Field Analysis" Incorrect options:
Option A (XSS): Exploits JavaScript injection, not for finding hidden fields.
Option B (On-path attack): Involves MITM interception, not directly analyzing form fields.
Option C (SQL injection): Targets databases, not HTML forms

NEW QUESTION # 132
During a security assessment, a penetration tester decides to write the following Python script: import requests x= ['OPTIONS', 'TRACE', 'TEST'l for y in x; z - requests.request(y, 'http://server.net') print(y, z.status_code, z.reason) Which of the following is the penetration tester trying to accomplish? (Select two).
- A. 'Web application firewall detection
- B. Web server error handling
- C. 'Web server fingerprinting
- D. HTTP methods availability
- E. Web server banner grabbing
- F. Web server denial of service
Answer: C,D
Explanation:
The Python script mentioned in the question is designed to send HTTP requests using different methods ('OPTIONS', 'TRACE', 'TEST') to a specified URL ('http://server.net') and print out the method used along with the status code and reason for each response. The key objectives of this script are:
HTTP Methods Availability (B): By cycling through different HTTP methods, the script checks which methods are supported by the web server. This can reveal potential vulnerabilities, as certain methods like 'TRACE' can be exploited in certain situations (e.g., Cross Site Tracing (XST) attacks).
Web Server Fingerprinting (D): The response to different HTTP methods can provide clues about the web server's software and configuration, contributing to server fingerprinting. This information can be used to tailor further attacks or understand the security posture of the server.
This script is not designed for causing a denial of service, detecting web application firewalls, examining error handling, or performing banner grabbing directly, which excludes options A, C, E, and F.
