A penetration tester needs to confirm the version number of a client's web application server. Which of the following techniques should the penetration tester use?
Correct Answer:
C
Banner grabbing is a technique used to gather information about a service running on an open port, which often includes the version number of the application or server. Here??s why banner grabbing is the correct Answer
✑ Banner Grabbing: It involves connecting to a service and reading the welcome banner or response, which typically includes version information. This is a direct method to identify the version number of a web application server.
✑ SSL Certificate Inspection: While it can provide information about the server, it is not reliable for identifying specific application versions.
✑ URL Spidering: This is used for discovering URLs and resources within a web application, not for version identification.
✑ Directory Brute Forcing: This is used to discover hidden directories and files, not for identifying version information.
References from Pentest:
✑ Luke HTB: Shows how banner grabbing can be used to identify the versions of services running on a server.
✑ Writeup HTB: Demonstrates the importance of gathering version information through techniques like banner grabbing during enumeration phases.
Conclusion:
Option C, banner grabbing, is the most appropriate technique for confirming the version number of a web application server.

A penetration tester downloads a JAR file that is used in an organization's production environment. The tester evaluates the contents of the JAR file to identify potentially vulnerable components that can be targeted for exploit. Which of the following describes the tester's activities?
Correct Answer:
D
The tester??s activity involves analyzing the contents of a JAR file to identify potentially vulnerable components. This process is known as Software Composition Analysis (SCA). Here??s why:
✑ Understanding SCA:
✑ Comparison with Other Terms:
The tester??s activity of examining a JAR file for vulnerable components aligns with SCA, making it the correct answer.

A penetration tester performs a service enumeration process and receives the following result after scanning a server using the Nmap tool:
PORT STATE SERVICE
22/tcp open ssh 25/tcp filtered smtp 111/tcp open rpcbind 2049/tcp open nfs
Based on the output, which of the following services provides the best target for launching an attack?
Correct Answer:
D
Based on the Nmap scan results, the services identified on the target server are as follows:
✑ 22/tcp open ssh:
✑ 25/tcp filtered smtp:
✑ 111/tcp open rpcbind:
✑ 2049/tcp open nfs:
Conclusion: The NFS service (2049/tcp) provides the best target for launching an attack. File sharing services like NFS often contain sensitive data and can be vulnerable to misconfigurations that allow unauthorized access or privilege escalation.
Which of the following components should a penetration tester include in an assessment report?
Correct Answer:
D
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.

During a security assessment, a penetration tester needs to exploit a vulnerability in a wireless network's authentication mechanism to gain unauthorized access to the network. Which of the following attacks would the tester most likely perform to gain access?
Correct Answer:
C
MAC address spoofing involves changing the MAC address of a network interface to mimic another device on the network. This technique is often used to bypass network access controls and gain unauthorized access to a network.
