CompTIA PT0-002 CompTIA PenTest+ Certification Exam Exam Practice Test

Server-side request forgery (SSRF) is the vulnerability that the tester exploited by querying the provider’s metadata and getting the credentials used by the instance to authenticate itself. SSRF is a type of attack that abuses a web application to make requests to other resources or services on behalf of the web server. This can allow an attacker to access internal or external resources that are otherwise inaccessible or protected. In this case, the tester was able to access the metadata service of the cloud provider, which contains sensitive information about the instance, such as credentials, IP addresses, roles, etc.

since vlan hopping requires 2 vlans to be nested in a single packet. Double tagging occurs when an attacker adds and modifies tags on an Ethernet frame to allow the sending of packets through any VLAN. This attack takes advantage of how many switches process tags. Most switches will only remove the outer tag and forward the frame to all native VLAN ports. With that said, this exploit is only successful if the attacker belongs to the native VLAN of the trunk link.

Tag nesting is a technique that involves inserting two VLAN tags into an Ethernet frame to bypass VLAN hopping prevention mechanisms. The first tag is stripped by the first switch, and the second tag is processed by the second switch, allowing the frame to reach a different VLAN than intended. RFID cloning is a technique that involves copying the data from an RFID tag to another tag or device. RFID tagging is a technique that involves attaching an RFID tag to an object or person for identification or tracking purposes. Meta tagging is a technique that involves adding metadata to web pages or files for search engine optimization or classification purposes.

URL enumeration is the activity of discovering and mapping the URLs of a website, such as directories, files, parameters, or subdomains. URL enumeration can help to identify the structure, content, and functionality of a website, as well as potential vulnerabilities or misconfigurations. One of the methods of URL enumeration is to analyze the robots.txt file of a website, which is a text file that tells search engine crawlers which URLs the crawler can or can’t request from the site1. The output shown in the question is an example of a robots.txt file that disallows crawling of certain URLs, such as /author/, /xmlrpc.php, /wp-admin, or /page/.

the NMAP flag (-sn) which is for host discovery and returns that kind of NMAP output. And the AWK command selects column 5 ({print $5}) which obviously carries the returned IP of the host in the NMAP output.

This command will generate the results shown in the image and transform them into a list of active hosts for further analysis. The command consists of three parts:

nmap -sn 192.168.0.1-254: This part uses nmap, a network scanning tool, to perform a ping scan (-sn) on the IP range 192.168.0.1-254, which means sending ICMP echo requests to each IP address and checking if they respond.

grep “Nmap scan”: This part uses grep, a text filtering tool, to search for the string “Nmap scan” in the output of the previous part and display only the matching lines. This will filter out the lines that show the start and end time of the scan and only show the lines that indicate the status of each host.

awk ‘{print $5}’: This part uses awk, a text processing tool, to print the fifth field ($5) of each line in the output of the previous part. This will extract only the IP addresses of each host and display them as a list.

The final output will look something like this:

192.168.0.1 192.168.0.12 192.168.0.17 192.168.0.34

The Nmap Scripting Engine (NSE) is one of Nmap's most powerful and flexible features. It allows users to write (and share) simple scripts (using the Lua programming language ) to automate a wide variety of networking tasks.

 Creating a script in the Lua language and using it with NSE would best support the objective of finding a vulnerability that enables attackers to open doors via a specialized TCP service that is used for a physical access control system. NSE (Nmap Scripting Engine) is a feature of Nmap that allows users to write and run scripts to automate tasks or perform advanced scans. Lua is a scripting language that NSE supports and can be used to create custom scripts for Nmap.

The VRFY and EXPN commands can be used to enumerate user accounts on an SMTP server, as they are used to verify the existence of users or mailing lists. VRFY (verify) asks the server to confirm that a given user name or address is valid. EXPN (expand) asks the server to expand a mailing list into its individual members. These commands can be used by a penetration tester to identify valid user names or e-mail addresses on the target SMTP server.

S/MIME stands for Secure/Multipurpose Internet Mail Extensions and is a standard for encrypting and signing email messages. It uses public key cryptography to ensure the confidentiality, integrity, and authenticity of email communications. FTPS is a protocol for transferring files securely over SSL/TLS, but it is not used for emailing. DNSSEC is a protocol for securing DNS records, but it does not protect email content. AS2 is a protocol for exchanging business documents over HTTP/S, but it is not used for emailing.

OpenVAS is a full-featured vulnerability scanner.

OWASP ZAP = Burp Suite

Drozer (Android) = drozer allows you to search for security vulnerabilities in apps and devices by assuming the role of an app and interacting with the Dalvik VM, other apps' IPC endpoints and the underlying OS.

Part 1 - 192.168.2.2 -O -sV --top-ports=100 and SMB vulns

Part 2 - Weak SMB file permissions

The tester is attempting to determine active hosts on the network by writing a script that pings a range of IP addresses. Ping is a network utility that sends ICMP echo request packets to a host and waits for ICMP echo reply packets. Ping can be used to test whether a host is reachable or not by measuring its response time. The script uses a for loop to iterate over a range of IP addresses from 192.168.1.1 to 192.168.1.254 and pings each one using the ping command with -c 1 option, which specifies one packet per address.

A. IP addresses and subdomains. This is correct. IP addresses and subdomains are useful information for a penetration tester to identify the scope and range of the company’s web presence. IP addresses can reveal the location, network, and service provider of the company’s web servers, while subdomains can indicate the different functions and features of the company’s website. A penetration tester can use tools like whois, Netcraft, or DNS lookups to find IP addresses and subdomains associated with the company’s domain name.

D. Internet search engines. This is correct. Internet search engines are powerful tools for a penetration tester to perform passive information gathering around the company’s web presence. Search engines can provide a wealth of information, such as the company’s profile, history, news, social media accounts, reviews, products, services, customers, partners, competitors, and more. A penetration tester can use advanced search operators and keywords to narrow down the results and find relevant information. For example, using the site: operator can limit the results to a specific domain or subdomain, while using the intitle: operator can filter the results by the title of the web pages.

Creating a one-shot system service to establish a reverse shell is a technique that would best support maintaining persistence after reboot on a Linux-based file server. A system service is a program that runs in the background and performs various tasks without user interaction. A one-shot system service is a type of service that runs only once and then exits. A reverse shell is a type of shell that connects back to an attacker-controlled machine and allows remote command execution. By creating a one-shot system service that runs a reverse shell script at boot time, the penetration tester can ensure persistent access to the file server even after reboot.

All other answers are a form of encryption or randomizing the data.

PS/PA/PU/PY are host discovery flags which use TCP SYN/ACK, UDP or SCTP discovery respectively. And since the ports in the options are mostly used by TCP protocols, then it's either the PS or PA flag. But since we need to know if the ports are live, sending SYN packet is a better alternative. Hence, I choose PS in this case.

The nmap –PS22-25,80 192.168.1.1-5 command will return vulnerable ports that might be interesting to a potential attacker, as it will perform a TCP SYN scan on ports 22, 23, 24, 25, and 80 of the target hosts. A TCP SYN scan is a stealthy technique that sends a SYN packet to each port and waits for a response. If the response is a SYN/ACK packet, it means the port is open and listening for connections. If the response is a RST packet, it means the port is closed and not accepting connections. If there is no response, it means the port is filtered by a firewall or IDS1.

The statement of work (SOW) is a document that defines the scope, objectives, deliverables, and timeline of a penetration testing engagement. It is important to have the client sign the SOW before starting the assessment to avoid any legal or contractual issues.

Clarifying the statement of work is one of the most important items to develop fully prior to beginning the penetration testing activities, as it defines the scope, objectives, deliverables, and expectations of the engagement. The statement of work is a formal document that outlines the agreement between the penetration tester and the client and serves as a reference for both parties throughout the engagement. It should include details such as the type, duration, and frequency of testing, the target systems and networks, the authorized methods and tools, the reporting format and schedule, and any legal or ethical considerations.

 The commands are used to clear the Bash history file of the current user, which records the commands entered in the terminal. The first command redirects /dev/null (a special file that discards any data written to it) to temp, which creates an empty file named temp. The second command changes the timestamp of temp to match that of .bash_history (the hidden file that stores the Bash history). The third command renames temp to .bash_history, which overwrites the original file with an empty one. This effectively erases any trace of the commands executed by the user.

"A significant issue identified by Wiberg is that using active network scanners, such as Nmap, presents a weakness when attempting port recognition or service detection on SCADA devices. Wiberg states that active tools such as Nmap can use unusual TCP segment data to try and find available ports. Furthermore, they can open a massive amount of connections with a specific SCADA device but then fail to close them gracefully." And since SCADA and ICS devices are designed and implemented with little attention having been paid to the operational security of these devices and their ability to handle errors or unexpected events, the presence idle open connections may result into errors that cannot be handled by the devices.

SMTP is a protocol associated with mail servers. Therefore, for a penetration tester, an open relay configuration can be exploited to launch phishing attacks.

The heart bleed bug is an open ssl bug which does not affect SSH Ref:

The penetration tester should send deauthentication frames to the stations to force them to disconnect from their current access point and reconnect to another one, which may be the malicious AP deployed by the tester. Deauthentication frames are part of the 802.11 protocol and are used to terminate an existing wireless association between a station and an access point. However, they can also be spoofed by an attacker to disrupt or hijack wireless connections. The other options are not effective or relevant for this purpose. Performing jamming on all 2.4GHz and 5GHz channels would interfere with all wireless signals in the area, which may cause unwanted attention or legal issues. Setting the malicious AP to broadcast within dynamic frequency selection channels would not help, as these channels are used to avoid interference with radar systems and are not commonly used by wireless stations or access points. Modifying the malicious AP configuration to not use a pre-shared key would not help, as it would make it less likely for wireless stations to connect to it if they are configured to use encryption.

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.

Impersonation attacks involve the penetration tester assuming the identity of a valid user to gain unauthorized access to systems or information. This method is particularly effective for gathering valid user credentials, as it can involve tactics such as phishing, social engineering, or exploiting weak authentication processes. The other options, such as Wardriving, Captive portal, and Deauthentication, are more focused on wireless network vulnerabilities and are less direct in obtaining user credentials.

IoT devices are often shipped with default passwords, which are easily discoverable and widely known. Many users fail to change these default credentials, leaving the devices vulnerable to unauthorized access. This issue is one of the most common vulnerabilities associated with IoT devices connected directly to the internet. Attackers can exploit these default passwords to gain control over the devices, potentially leading to a range of malicious activities, including the recruitment of the devices into botnets for Distributed Denial of Service (DDoS) attacks, data breaches, or other cybercriminal activities.

The cme smb 192.168.0.0/24 -u /userList.txt -p /passwordList.txt command is used to perform SMB enumeration on the 192.168.0.0/24 subnet using a list of usernames and passwords. The -u option specifies the file containing the usernames, and the -p option specifies the file containing the passwords1. This command allows the tester to attempt to authenticate with multiple accounts without locking any of them out. References: SMB Command

A directory traversal attack, also known as a path traversal attack, is a method used to exploit insufficient security validation or sanitization of user-supplied input file names. The goal of this attack is to access directories and files that are stored outside the web root folder. By manipulating variables that reference files with “../” sequences and its variations, attackers can access restricted directories and execute commands outside of the web server’s root directory.

In the context of an application that allows users to upload documents to a cloud-based file server, an attacker might exploit a directory traversal vulnerability to navigate to directories that contain sensitive documents. If the file upload functionality is not properly secured, an attacker could upload a file with a payload designed to perform directory traversal. This could allow access to confidential files that are otherwise protected by the application's access control mechanisms.

The communication escalation path is a component of the Rules of Engagement (ROE) that provides a penetration tester with guidance on whom to contact and how to proceed in the event of an emergency or disaster during an engagement. This includes contact information for key individuals and predefined procedures to follow to ensure that any issues are addressed promptly and appropriately.

The engagement scope defines the boundaries and objectives of the test, the SLA (Service Level Agreement) outlines performance and uptime requirements, and the SOW (Statement of Work) details the tasks and deliverables. However, the communication escalation path specifically addresses communication protocols during emergencies.

Requiring local network access for the default Admin User account is a targeted measure to prevent unauthorized access from unfamiliar IP addresses, particularly those originating from outside the organization's network. This approach ensures that only devices physically connected to or authenticated within the local network can attempt to use the Admin User account, significantly reducing the risk of external attacks. Increasing password complexity and restricting simultaneous log-ins are good practices but do not directly address the issue of access from unfamiliar IPs. System hardening is broader and not specifically focused on the Admin User account issue.

To understand and exploit the vulnerability causing the server application to crash or remain stable after opening several simultaneous connections, the best approach is to attach a remote debugger to the application. This allows the penetration tester to monitor the application’s behavior in real-time without affecting the stability of the testing environment. Establishing a large number of connections to the server and sending fixed packets of data simultaneously can help to reproduce the issue consistently, which is crucial for identifying the cause of the crashes. Analyzing the application's response and debugging data will provide insights into potential buffer overflow, race conditions, or other vulnerabilities.

 Deauthentication attacks can force legitimate users to disconnect from a wireless network, prompting them to reconnect and, in the process, capture valid user credentials using a rogue access point or network monitoring tools.

 Details:

A. Wardriving: Involves driving around to discover wireless networks; it does not directly gather user credentials.

B. Captive portal: Requires users to log in but is not an attack method; it is a legitimate method to control network access.

C. Deauthentication: Forces users to reauthenticate, allowing an attacker to capture credentials during the reconnection process.

D. Impersonation: Involves pretending to be someone else to gain access but is less effective for directly capturing user credentials compared to deauthentication.

 References: Deauthentication attacks are well-documented in wireless security assessments and penetration testing guides.

Given the Nmap scan results showing an open HTTP service on port 8080 running Microsoft IIS 9.0, the next logical step for the penetration tester would be to further explore the web server. Nikto is a web server scanner that can identify known vulnerabilities, configuration issues, and other security problems.

Using the command nikto -host will initiate a scan against the HTTP service on the target server, helping the tester to identify potential weaknesses that could be exploited.

To correctly return the password for the user "ozzy" from the given JSON structure, the Python code snippet should navigate the nested structure appropriately. The "content" array contains objects with "user_id" and "password" fields. The correct password for "ozzy" can be accessed using the code json['content'][1]['password'][0], which navigates to the second object in the "content" array (index 1) and then accesses the first element (index 0) of the "password" array for that user.

 Using PGP (Pretty Good Privacy) encryption ensures that the report file is securely encrypted with the client's public key. Only the client can decrypt the file using their private key, ensuring confidentiality during transit.

 Details:

Option Analysis:

A. Creating a link on a cloud service and delivering it by email: This method is susceptible to interception or unauthorized access.

B. Asking for a PGP public key to encrypt the file: Provides end-to-end encryption ensuring that only the intended recipient can access the file.

C. Requiring FTPS security to download the file: While secure, it does not provide the same level of end-to-end encryption as PGP.

D. Copying the file on a USB drive and delivering it by postal mail: While physically secure, it is not practical and poses a risk of loss or theft.

 References: PGP encryption is a widely accepted method for securing sensitive data. It is recommended by many cybersecurity standards and best practice guides.

The single quote mark (') is a common character used to test for SQL injection vulnerabilities. This character is often used to terminate a string in SQL queries. By injecting a single quote mark into an input field, a penetration tester can determine whether the application is susceptible to SQL injection based on the resulting error messages or behavior of the application.

The single quote mark is typically used first because it is straightforward and effective in revealing SQL injection flaws. Other characters like double quotes or semicolons might also be useful in specific contexts, but the single quote is the standard starting point for SQL injection testing.

In the context of penetration testing or cybersecurity, hiring a consultant with a background in unauthorized system access could present both risks and benefits. From a risk management perspective, Candidate 2's history of unauthorized system access is a significant red flag. Such past behavior indicates a willingness to operate outside of legal and ethical boundaries, which could pose a risk to the firm and its clients, especially in a role that requires trust and adherence to legal guidelines.

However, the very skills that enabled unauthorized access might also provide the firm with deep insights into hacker methodologies, potentially enhancing the firm's capability to secure systems against such intrusions. It is a common practice in the cybersecurity industry to employ individuals with a history of hacking in roles where they can contribute positively, known as "ethical hacking" or "white hat" roles.

Nonetheless, given the legal and ethical responsibilities inherent in cybersecurity work, Candidate 2's past criminal charge of unauthorized system access is the most pertinent to the role and poses the most direct risk to the firm's operations and reputation. It would be crucial for the firm to conduct a thorough risk assessment, including the nature of the unauthorized access, the candidate's subsequent actions, rehabilitation, and current capabilities, before making a hiring decision.

From the provided information, it appears that Candidate 2 should most likely be excluded from consideration due to the direct relevance of their criminal charges to the position in question. Without evidence of rehabilitation and a clear demonstration of ethical standards, the liability risks might outweigh the potential benefits to the firm.

The best way to mitigate this issue is to implement patching and change control programs, which are processes that involve applying updates or fixes to software packages to address vulnerabilities, bugs, or performance issues, and managing or documenting the changes made to the software packages to ensure consistency, compatibility, and security. Patching and change control programs can help prevent or reduce the risk of attacks that exploit outdated software package versions, which may contain known or unknown vulnerabilities that can compromise the security or functionality of the systems or servers. Patching and change control programs can be implemented by using tools such as WSUS, which is a tool that can manage and distribute updates for Windows systems and applications1, or Git, which is a tool that can track and control changes to source code or files2. The other options are not valid ways to mitigate this issue. Revision of client scripts used to perform system updates is not a sufficient way to mitigate this issue, as it may not address the root cause of why the software package versions are outdated, such as lack of awareness, resources, or policies. Remedial training for the client’s systems administrators is not a direct way to mitigate this issue, as it may not result in immediate or effective actions to update the software package versions. Refrainment from patching systems until quality assurance approves is not a way to mitigate this issue, but rather a potential cause or barrier for why the software package versions are outdated.

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.

The Nmap command in the question aims to use custom NSE scripts stored in a specific folder. The correct syntax for this option is to use the script argument followed by the path to the folder. The other commands are either invalid, use the wrong argument, or do not specify the folder path. References: Best PenTest+ certification study resources and training materials, CompTIA PenTest+ PT0-002 Cert Guide, 101 Labs — CompTIA PenTest+: Hands-on Labs for the PT0-002 Exam

In the scenario where users are mistyping the name of a fileshare server, leading to broadcast requests, the most effective exploitation strategy would be for the penetration tester to respond to these requests with their own IP address (D) and set up a service to capture authentication credentials. This technique is known as a "Man-in-the-Middle" (MitM) attack, where the attacker intercepts communication between two parties. In this case, the tester can exploit the misdirected requests to potentially capture sensitive information such as usernames and passwords.

A watering hole attack involves compromising a website that is frequently visited by the target organization or group. By gaining control of the internal web server hosting the IT knowledge base, a penetration tester could modify the content or introduce malicious code that would be downloaded or executed by employees who visit the site. This type of attack is effective because it leverages a trusted resource within the organization to spread malware or capture sensitive information.

Other options like vishing, whaling, and spear phishing involve direct social engineering attacks targeting individuals, whereas a watering hole attack leverages a compromised website to target multiple users within the organization.

ARP poisoning is a technique that exploits the weakness of the ARP protocol to redirect network traffic to a malicious host. Ettercap is a tool that can perform ARP poisoning and other network attacks, such as DNS spoofing, SSL stripping, and password sniffing. Wireshark, Netcat, and Nmap are not designed for ARP poisoning, although they can be used for other purposes, such as packet analysis, network communication, and port scanning.

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.

The risk present in an organization using Android mobile devices without Mobile Device Management (MDM) services is that unsigned applications can be installed. Without MDM, there are fewer controls over the installation of applications, which increases the risk of installing malicious or unauthorized applications. MDM services typically provide a way to enforce application signing policies, preventing the installation of unsigned apps.

When the penetration tester has NOPASSWD privileges to run vi as root, the quickest way to escalate privileges is to leverage vi to execute a shell. The command sudo vi -c ':!bash' opens vi as the root user and immediately spawns a shell within vi. This method is fast and effective because vi (or vim) has the capability to run shell commands.

Executing sudo vi -c ':!bash' will open vi and then immediately run the :!bash command, which spawns a Bash shell with root privileges.

The Nmap command uses the Xmas scan technique, which sends packets with the FIN, PSH, and URG flags set. This is an attempt to bypass firewall rules and elicit a response from open ports. However, if the target responds with an RST packet, it means that the port is closed. Open ports will either ignore the Xmas scan packets or send back an ACK packet. Therefore, the information most likely indicates that all of the ports in the target range are closed.

The most efficient way to write a Python script that interacts with web applications is to import the requests library. The requests library is a Python HTTP library that simplifies making HTTP requests to web servers, which is essential for interacting with web applications. It allows you to easily send HTTP/1.1 requests, without the need for manually adding query strings to your URLs, or form-encode your POST data. Options A and B involve creating a class or function for requests, which could be more time-consuming and less efficient than using a well-established library like requests. Option D, using the cURL OS command, is less efficient in a Python script since it involves calling an external command rather than using a native Python library.

Variable initialization is the process of assigning a value to a variable at the time of declaration. In Java and C/C++, variable initialization is critical because if a variable is not initialized, it may contain a garbage value that is unpredictable and may lead to erroneous results or runtime errors when the variable is used later in the program. For example, if a variable is used in a mathematical expression or a conditional statement, the outcome may depend on the value of the variable. If the variable is not initialized, the outcome may be different each time the program is run, or the program may crash due to an invalid operation. Therefore, it is a good practice to always initialize variables before using them, or to check if they have been initialized before using them123. References:

The PHP file uploaded by the penetration tester allows for Remote Code Execution (RCE) by executing the command supplied through the cmd POST parameter. To exploit this, the penetration tester needs to send a POST request to the PHP file with the command they want to execute.

Among the given options, Option A is the most suitable for achieving RCE:

It uses Python's requests library to send a POST request, which is appropriate because the PHP script expects data through the POST method.

The data parameter in the requests.post function is correctly formatted as a dictionary, which is the expected format for sending form data in POST requests. It includes the key cmd with the value id, which is a common command used to display the current user ID and group ID.

The only minor issue with Option A is that it prints the entire response object, which includes not just the response content but also metadata like status code and headers. To print just the response content (which would include the output of the id command), appending .text to the requests.post call would be more precise, but this is a small detail and does not affect the execution of the command.

The other options have various issues:

Option B is close but has a syntax error in the data argument. It uses parentheses () instead of curly braces {} for the dictionary, and also lacks the .text at the end to print the response content.

Options C and D use the requests.get method, which is not suitable in this scenario because the PHP script is expecting data through the POST method, not the GET method. Additionally, Option D has a syntax error similar to Option B.

Prioritizing findings in a penetration test report should align with the business mission and goals. Understanding the business context allows a penetration tester to assess the impact of vulnerabilities in relation to the organization's critical functions and assets. This approach ensures that recommendations are not only technically sound but also relevant and actionable within the business's strategic framework. Options B, C, and D (Cyberassets, Network infrastructure, and Cyberthreats) are important factors but should be considered within the context of how they affect the business's mission and goals.

Snow is a tool designed for steganography, which is the practice of concealing messages or information within other non-secret text or data. In this context, Snow is specifically used to hide data within whitespace of text files, which can include the whitespace areas of images saved in formats that support text descriptions or metadata, such as certain PNG or JPEG files. While the other tools listed (Kismet, Responder, Metasploit) are powerful in their respective areas (network sniffing, LLMNR/NBT-NS poisoning, and exploitation framework), they do not offer functionality related to data concealment in image files or steganography.

 Detecting a Web Application Firewall (WAF) helps penetration testers understand the protective measures in place and tailor their testing methods to bypass these defenses.

 Details:

A. Direct-to-origin testing: Useful for bypassing CDN but not specifically for detecting protective mechanisms like WAF.

B. Antivirus scanning: Not relevant for web application attacks.

C. Scapy packet crafting: Useful for network-level testing but not for detecting web application protections.

D. WAF detection: Identifies if a WAF is present, which is critical for understanding and bypassing web application defenses.

 References: WAF detection techniques are documented in web application security testing methodologies such as OWASP.

Most likely vulnerability: Perform a SSRF attack against App01.example.com from CDN.example.com.

The scenario suggests that the CDN network (with a WAF) can be used to perform a Server-Side Request Forgery (SSRF) attack. Since the penetration tester has the pentester workstation interacting through the CDN/WAF and the production network is behind it, the most plausible attack vector is to exploit SSRF to interact with the internal services like App01.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.

 The provided output reveals a common vulnerability in Windows services known as an unquoted service path. When the service executable path is not enclosed in quotes and contains spaces, Windows may incorrectly interpret the spaces, potentially leading to the execution of unintended programs.

Output Interpretation: The output shows a service with a path C:\Program Files\A Subfolder\B Subfolder\SomeExecutable.exe which is not quoted. If a malicious user places an executable in C:\Program.exe, C:\Program Files\A.exe, or similar, it might get executed instead.

 References: Common Windows privilege escalation vulnerabilities include unquoted service paths. This vulnerability is well-documented in security resources and penetration testing guides.

HaveIBeenPwned is a website that allows users to check if their personal data has been compromised by data breaches. For a penetration tester preparing a credential stuffing attack, HaveIBeenPwned can provide valuable information about which accounts and passwords have been exposed, making them more likely targets for successful credential stuffing. This passive information gathering tool can help in identifying the most relevant credentials without actively probing the target's systems. The other tools listed (Shodan, BeEF, Maltego) serve different purposes, such as device and service enumeration, client-side exploitation, and information gathering through different means, respectively.

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.

The payload file=/proc/self/environ is used to exploit Local File Inclusion (LFI) vulnerabilities in web applications running on Linux systems. This payload allows the attacker to read the environment variables of the process running the web server, which can include sensitive information such as credentials, system paths, and configuration details. The other payloads mentioned are not as directly relevant to obtaining running process credentials in the context of an LFI vulnerability.

 System hardening involves securing a system by reducing its surface of vulnerability, which includes changing default credentials, disabling unnecessary services, and applying security patches.

 Details:

A. Password encryption: Secures passwords but does not address the issue of default credentials.

B. System hardening: Comprehensive approach to securing the system, including changing default credentials.

C. Multifactor authentication: Adds an additional layer of security but does not solve the problem of default credentials being enabled.

D. Patch management: Ensures software is up-to-date but does not directly address default credentials.

 References: System hardening is a fundamental practice in securing systems and preventing unauthorized access, as detailed in security best practices and guidelines.

The -T2 flag in Nmap sets the timing template to “polite”, which means that Nmap will limit the number of parallel probes to 10 and the scan delay to 0.4 seconds. This will reduce the number of connections per minute and avoid triggering the active response tool. The -Pn flag tells Nmap to skip the host discovery phase and scan the target regardless of its ping response. The other options are not suitable for bypassing the active response tool, as they either scan too many ports (-sU, -T5, -F) or use a faster timing template (-T5, -T3) that will generate more connections per minute.

The presence of plaintext strings that can be used to move laterally across the network suggests that passwords or sensitive tokens are stored insecurely. Implementing a password management solution would help mitigate this issue by ensuring that passwords are stored securely and are not exposed in plaintext. Password managers typically use strong encryption to protect stored credentials and provide secure access to them.

Sanitizing user input, rotating keys, and utilizing certificate management address different aspects of security but do not directly resolve the issue of insecure password storage.

Examples of security breaches due to poor password management practices: Forge​​.

The output shows multiple login attempts with different passwords for the same username “root” on the IP address 192.168.1.112. This is indicative of a brute force attack, where an attacker systematically tries various password combinations to gain unauthorized access. References: The Official CompTIA PenTest+ Study Guide (Exam PT0-002), Chapter 4: Conducting Passive Reconnaissance; The Official CompTIA PenTest+ Student Guide (Exam PT0-002), Lesson 4: Conducting Active Reconnaissance.

A list is a data structure in Python that can store multiple values of different types in a sequential order. A list is created by enclosing the values in square brackets [ ] and separating them by commas. A list can also contain other lists as its elements, creating a nested or multidimensional list. The output of the print (var) statement shows that var is a list that contains two elements, each of which is another list with two key-value pairs. The key-value pairs are enclosed in curly braces { }, which indicate that they are dictionaries, another data structure in Python that maps keys to values. Therefore, var is a list of dictionaries.

When a penetration tester obtains a list of password digests using Responder, the next logical step is to attempt to crack these password hashes to retrieve the plaintext passwords. Hashcat is one of the most widely used tools for this purpose. It is a high-performance password recovery tool that supports a wide range of hashing algorithms and can utilize the power of GPU acceleration to significantly speed up the cracking process.

Hashcat is preferred over tools like Hydra, CeWL, and Medusa in this context because it is specifically designed for cracking password hashes rather than brute-forcing login credentials (Hydra, Medusa) or generating custom wordlists (CeWL).

Usage examples in various penetration testing reports, including those involving password cracking and hash manipulation​​​​.

The output provided indicates the use of the NTP protocol (Network Time Protocol) for querying a target system. The reference to "Public Clients" and the specific IP addresses listed, along with the mention of "Other Associations" and the use of NTP version 2, points towards the execution of an NTP monlist request. The monlist feature in NTP servers can be used to obtain a list of the last 600 hosts that have interacted with the NTP server. The command nmap -sU -pU:123 -Pn -n —script=ntp-monlist <target> specifically targets NTP servers on UDP port 123 to retrieve this information, making it the correct choice based on the output shown.

Spear phishing is a type of targeted attack where the attacker sends emails that appear to come from a legitimate source, often a company or someone familiar to the target, with the goal of tricking the target into clicking on a malicious link or providing sensitive information. In this case, the penetration tester has already gathered OSINT on the IT system administrator, so they can use this information to craft a highly targeted spear phishing attack to try and gain access to the target system.

Based on these results, the most likely attack to succeed is a Heartbleed attack. The Heartbleed attack is a vulnerability in the OpenSSL implementation of the TLS/SSL protocol that allows an attacker to read the memory of the server and potentially steal sensitive information, such as private keys, passwords, or session tokens. The results show that the website is using OpenSSL 1.0.1f, which is vulnerable to the Heartbleed attack1.

One of the factors that a penetration tester would most likely consider when testing at a location is to establish the time of day when a test can occur. This factor can affect the scope, duration, and impact of the test, as well as the availability and response of the client and the testers. Testing at different times of day can have different advantages and disadvantages, such as testing during business hours to simulate realistic scenarios and traffic patterns, or testing after hours to reduce disruption and interference. Testing at different locations may also require adjusting for different time zones and daylight saving times. Establishing the time of day when a test can occur can help plan and coordinate the test effectively and avoid confusion or conflict with the client or other parties involved in the test. The other options are not factors that a penetration tester would most likely consider when testing at a location.

SQL injection is a type of attack that exploits a vulnerability in a web application that allows an attacker to execute malicious SQL statements on a database server. SQL injection can result in data theft, data corruption, authentication bypass, or command execution. To mitigate SQL injection vulnerabilities, the following remediation techniques are recommended:

Users’ input validation: This involves checking and sanitizing the user input before passing it to the database server. Input validation can prevent malicious or unexpected input from reaching the database server and causing harm. Input validation can be done by using whitelists, blacklists, regular expressions, or escaping mechanisms.

Parameterized queries: This involves using placeholders or parameters for user input instead of concatenating it with the SQL statement. Parameterized queries can separate the user input from the SQL logic and prevent it from being interpreted as part of the SQL statement. Parameterized queries can be implemented by using prepared statements, stored procedures, or frameworks that support them. The other options are not relevant or effective remediation techniques for SQL injection vulnerabilities.

A hypervisor is a type of virtualization software that allows multiple virtual machines (VMs) to run on a single physical host machine. If the hypervisor is compromised, an attacker could potentially gain access to all of the VMs running on that host, which could lead to a significant data breach or other security issues.

One common type of attack against hypervisors is known as a VM escape attack. In this type of attack, an attacker exploits a vulnerability in the hypervisor to break out of the VM and gain access to the host machine. From there, the attacker can potentially gain access to other VMs running on the same host.

By ensuring that all hypervisors have the latest available patches installed, the company can reduce the likelihood that a VM escape attack will be successful. Patches often include security updates and vulnerability fixes that address known issues and can help prevent attacks.

The document that is agreed upon by all parties associated with the penetration-testing engagement and defines the scope, contacts, costs, duration, and deliverables is the SOW (Statement of Work). The SOW is a formal document that describes the objectives, expectations, and responsibilities of the penetration-testing project2. The SOW should be clear, concise, and comprehensive to avoid any ambiguity or misunderstanding.

The terms of engagement state that the penetration test should not include circumventing the alarm or performing destructive entry, which rules out options A and D. Option C is also not allowed, as it involves social engineering, which is not part of the scope. Option B is the only one that does not violate the terms of engagement, as it uses an open door from an adjoining building to gain access to the records room. This can help the penetration tester to test the physical security of the electronic records without breaking any rules.

"Exploit Database (ExploitDB) is a repository of exploits for the purpose of public security, and it explains what can be found on the database. The ExploitDB is a very useful resource for identifying possible weaknesses in your network and for staying up to date on current attacks occurring in other networks"

Exploit-DB is a website that collects and archives exploits for various software and hardware products, including network infrastructure devices. Exploit-DB allows users to search for exploits by product name, vendor, type, platform, CVE number, or date. Exploit-DB is a useful resource for obtaining payloads against specific network infrastructure products. Metasploit is a framework that contains many exploits and payloads, but it is not a resource for obtaining them. Shodan is a search engine that scans the internet for devices and services, but it does not provide exploits or payloads. Retina is a vulnerability scanner that identifies weaknesses in network devices, but it does not provide exploits or payloads.

The comment in the final report was intended for C-suite executives, which are senior-level managers or leaders in an organization, such as the chief executive officer (CEO), chief financial officer (CFO), or chief information officer (CIO). C-suite executives are typically interested in high-level summaries or overviews of the penetration test results, such as the percentage of systems affected by a certain vulnerability or risk, the potential impact or cost of a breach, or the recommended actions or priorities for remediation. C-suite executives may not have the technical background or expertise to understand detailed or technical information about the penetration test, such as specific vulnerabilities, exploits, tools, or techniques. The comment in the final report provides a high-level summary of the penetration test result that is relevant and understandable for C-suite executives. The other audiences are not likely to be interested in this comment. Systems administrators are technical staff who are responsible for installing, configuring, maintaining, and securing systems and networks. They would be more interested in detailed or technical information about the penetration test, such as specific vulnerabilities, exploits, tools, or techniques. Data privacy ombudsman is a person who acts as an independent mediator between individuals and organizations regarding data privacy issues or complaints. They would be more interested in information about how the penetration test complied with data privacy laws and regulations, such as GDPR or CCPA. Regulatory officials are authorities who enforce compliance with laws and regulations related to a specific industry or sector, such as finance, health care, or energy. They would be more interested in information about how the penetration test complied with industry-specific standards and frameworks, such as PCI-DSS, HIPAA, or NERC-CIP.

The most likely explanation for why a penetration tester cannot scan a server that was previously scanned successfully is that the IP address is on the blocklist. Blocklists are used to prevent malicious actors from scanning servers, and if the IP address of the server is on the blocklist, the scanning process will be blocked.

data structures are used to store data in an organized form, and some data structures are more efficient and suitable for certain operations than others. For example, hash tables, skip lists and jump lists are some dictionary data structures that can insert and access elements efficiently3.

For string comparison, there are different algorithms that can measure how similar two strings are, such as Levenshtein distance, Hamming distance or Jaccard similarity4. Some of these algorithms can be implemented using data structures such as arrays or hashtables5.

A vulnerability scan is a type of assessment that helps to identify vulnerabilities in a network or system. It scans systems for potential vulnerabilities, misconfigurations, and outdated software. Based on the output from a vulnerability scan, a penetration tester can identify vulnerabilities that may be exploited to gain access to a system. In this scenario, the output from the penetration testing tool shows that 100 hosts contained findings due to improper patch management. This indicates that the vulnerability scan detected vulnerabilities that could have been prevented through proper patch management. Therefore, the most likely test performed by the penetration tester is a vulnerability scan.

OLLYDBG, WinDBG, and IDA are all debugging tools that support Windows environments. GDB is a Linux‐specific debugging tool.

GDB is a tool that can be used to analyze and debug executable binaries, especially on Linux systems. GDB can disassemble, decompile, set breakpoints, examine memory, modify registers, and perform other operations on binaries. GDB can help a penetration tester understand the functionality, behavior, and vulnerabilities of an unknown binary. Peach is a tool that can be used to perform fuzzing, which is a technique of sending malformed or random data to a target to trigger errors or crashes. WinDbg and OllyDbg are tools that can be used to analyze and debug executable binaries, but they are mainly designed for Windows systems.

The best recommendation to remediate this vulnerability is to use parameterized queries in the web application. Parameterized queries are a way of preventing SQL injection attacks by separating the SQL statements from the user input. This way, the user input is treated as a literal value and not as part of the SQL statement. For example, instead of using x’ OR role LIKE '%admin%, the user input would be passed as a parameter to a prepared statement that would check if it matches any value in the database.

The file .scripts/daily_log_backup.sh has permissions set to 777, meaning that anyone can read, write, or execute the file. Since it's owned by the root user and the penetration tester has access to the system with a non-privileged account, this could be a potential avenue for privilege escalation. In a penetration test, after finding such a file, the tester would likely want to explore it and see if it can be leveraged to gain higher privileges. This is often done by inserting malicious code or commands into the script if it's being executed with higher privileges, such as root in this case.

 GDB is a debugging tool that can be used to analyze and manipulate the memory of a running process, which is useful for finding and exploiting buffer overflow vulnerabilities. Burp Suite is a web application testing tool that does not directly test for buffer overflows. SearchSpliot is a database of known exploits that does not test for new vulnerabilities. Netcat is a network utility that can be used to send and receive data, but not to test for buffer overflows.

 The arp command is used to manipulate or display the Address Resolution Protocol (ARP) cache, which is a table that maps IP addresses to physical addresses (MAC addresses) on a network. The -s option is used to add a static ARP entry to the cache, which means that it will not expire or be overwritten by dynamic ARP entries. The syntax for adding a static ARP entry is arp -s . Therefore, the command arp -s 192.168.1.63 60-36-DD-A6-C5-33 would add a static ARP entry for the IP address 192.168.1.63 and the physical address 60-36-DD-A6-C5-33 to the local cache of the attacker machine. This would allow the attacker machine to communicate with the target machine without relying on ARP requests or replies. The other commands are not valid or useful for establishing a static ARP entry.

The company that requested the penetration test is responsible for providing the correct and accurate network scope for the test. The network scope defines the boundaries and limitations of the test, such as which IP addresses, domains, systems, or networks are in scope or out of scope. If the company provided an incorrect network scope that included an IP address that belongs to a third party, then it is responsible for this mistake. The penetration testing company, the target host’s owner, the penetration tester, and the subcontractor supporting the test are not responsible for this mistake, as they relied on the network scope provided by the company that requested the penetration test.

The most likely explanation for what occurred is that the tester IP was blocked by the web server. The web server may have detected the web scanner as a malicious or suspicious activity and blocked the tester’s IP address from accessing the web application. This could result in an unauthorized to view this page message in the browser.

Cloud Custodian is a rules engine for managing public cloud accounts and resources. It allows users to define policies to enable a well managed cloud infrastructure, that's both secure and cost optimized. It consolidates many of the adhoc scripts organizations have into a lightweight and flexible tool, with unified metrics and reporting.

Cloud Custodian is a tool that can be used to manage public cloud accounts and resources. Cloud Custodian can define policies and rules for cloud resources based on various criteria, such as tags, filters, actions, modes, or schedules. Cloud Custodian can enforce compliance, governance, security, cost optimization, and operational efficiency for cloud resources. Cloud Custodian supports multiple public cloud providers, such as AWS, Azure, GCP, and Kubernetes. Cloud Brute is a tool that can be used to enumerate cloud platforms and discover hidden files and buckets. Pacu is a tool that can be used to exploit AWS environments and perform post-exploitation actions. Scout Suite is a tool that can be used to audit cloud environments and identify security issues.

The penetration tester violated the client’s request and the code of ethics by not reporting the vulnerability immediately and leaving it in place. This could have contributed to the breach and the data loss. The company should investigate the penetration tester’s actions and motives, and hold them accountable for any negligence or malpractice.

A dictionary is a data structure in Python that stores key-value pairs, where each key is associated with a value. A dictionary is created by enclosing the key-value pairs in curly braces and separating them by commas. A dictionary can be accessed by using the keys as indexes or by using methods such as keys(), values(), or items(). In the code, systems is a dictionary that has four key-value pairs, each representing an IP address and its corresponding operating system. A tuple is a data structure in Python that stores an ordered sequence of immutable values, enclosed in parentheses and separated by commas. A tree is a data structure that consists of nodes connected by edges, forming a hierarchical structure with a root node and leaf nodes. An array is a data structure that stores a collection of elements of the same type in a contiguous memory location.

Nmap is a tool that can perform network scanning and enumeration by sending packets to hosts and analyzing their responses. The command Nmap -p 445 -n -T4 --open 172.21.0.0/16 would scan for SMB port 445 over a /16 network with the following options:

-p 445 specifies the port number to scan.

-n disables DNS resolution, which can speed up the scan by avoiding unnecessary queries.

-T4 sets the timing template to aggressive, which increases the speed of the scan by sending packets faster and waiting less for responses.

–open only shows hosts that have open ports, which can reduce the output and focus on relevant results. The other commands are not optimal for scanning SMB port 445 over a /16 network when stealth is not a concern and the task is time sensitive.

The scoping document is a document that defines the objectives, scope, limitations, deliverables, and expectations of a penetration testing engagement. It is an essential document that guides the penetration testing process and ensures that both the tester and the client agree on the terms and conditions of the test. Requiring all testers to review the scoping document carefully would have most effectively prevented this misunderstanding, as it would have informed the new tester about the client’s request not to test the production networks. The other options are not effective or realistic ways to prevent this misunderstanding.

The best method available to pivot and gain additional access to the network is to span deauthentication packets to the wireless clients. This will cause them to disconnect from their wireless access point and reconnect using their hard-wired connection, which may have less restrictive ACLs. The penetration tester can then capture their traffic or attempt to compromise their systems.

The script author was trying to spawn a local shell by using the os.system() function, which executes a command in a subshell. The command being executed is “/bin/bash”, which is the path to the bash shell, a common shell program on Linux systems. The script author may have wanted to spawn a local shell to gain more control or access over the compromised system, or to execute other commands that are not possible in the original shell. The other options are not plausible explanations for what the script author was trying to do.

 The penetration tester is using a password brute force attack, which is a type of password guessing attack that involves trying many possible combinations of passwords against a single username or account. A password brute force attack can be effective when the password is known to be weak, simple, or predictable, such as a default or temporary password. In this case, the penetration tester knows that the help desk analysts change users’ passwords to 123change when they request password resets, and decides to brute force the webmail with this password and a list of usernames. A password brute force attack can be done by using tools such as Hydra, which can perform parallelized login attacks against various protocols and services1. The other options are not techniques that the penetration tester is using. SQL injection is a type of attack that exploits a vulnerability in a web application that allows an attacker to execute malicious SQL statements on a database server. Password spraying is a type of password guessing attack that involves trying one or a few common passwords against many usernames or accounts. Kerberoasting is a type of attack that exploits a vulnerability in the Kerberos authentication protocol that allows an attacker to request and crack service tickets for service accounts with weak passwords.

Credential harvesting is a type of attack that aims to collect usernames and passwords from unsuspecting users by tricking them into entering their credentials on a fake or spoofed website. Credential harvesting can be done by using phishing emails that lure users to click on malicious links or attachments that redirect them to the fake website. The fake website may look identical or similar to the legitimate one, but it will capture and store the user’s credentials for later use by the attacker. In this case, the penetration tester set up a fake cloud mail login page and sent phishing emails to all company employees to harvest their credentials.

A dictionary can be used to store alphanumeric data that can be fed into scripts or programs as input to penetration-testing tools. A dictionary is a collection of key-value pairs that can be accessed by using the keys. For example, a dictionary can store usernames and passwords, or IP addresses and hostnames, that can be used as input for brute-force or reconnaissance tools.

Removing shells: Remove any shell programs installed when performing

the pentest.

Removing tester-created credentials: Be sure to remove any user accounts

created during the pentest. This includes backdoor accounts.

Removing tools: Remove any software tools that were installed on the

customer’s systems that were used to aid in the exploitation of systems.

Situational awareness is the ability to perceive and understand the environment and events around oneself, and to act accordingly. The penetration tester demonstrated situational awareness by stopping the transfer of PII, which was out of scope and could have violated the ROE or legal and ethical principles. The other options are not relevant to the situation or the decision of the penetration tester.

fuzzing introduces unexpected inputs into a system and watches to see if the system has any negative reactions to the inputs that indicate security, performance, or quality gaps or issues

The document that describes activities that are prohibited during a scheduled penetration test is ROE, which stands for rules of engagement. ROE is a document that defines the scope, objectives, methods, limitations, and expectations of a penetration test. ROE can specify what activities are allowed or prohibited during the penetration test, such as which targets, systems, networks, or services can be tested or attacked, which tools, techniques, or exploits can be used or avoided, which times or dates can be scheduled or excluded, or which impacts or risks can be accepted or mitigated. ROE can help ensure that the penetration test is conducted in a legal, ethical, and professional manner, and that it does not cause any harm or damage to the client or third parties. The other options are not documents that describe activities that are prohibited during a scheduled penetration test. MSA stands for master service agreement, which is a document that defines the general terms and conditions of a contractual relationship between two parties, such as the scope of work, payment terms, warranties, liabilities, or dispute resolution. NDA stands for non-disclosure agreement, which is a document that defines the confidential information that is shared between two parties during a business relationship, such as trade secrets, intellectual property, or customer data. SLA stands for service level agreement, which is a document that defines the quality and performance standards of a service provided by one party to another party, such as availability, reliability, responsiveness, or security.

This is the most secure method for sending the penetration test report to the client because it ensures that only the client can decrypt and read the report using their private key. Encrypting the report with the client’s public key prevents anyone else from accessing the report, even if they intercept or compromise the email. The other methods are not as secure because they rely on weaker or no encryption, or they expose the report to third-party services that may not be trustworthy or compliant.
