A penetration tester gains access to a Windows machine and wants to further enumerate users with native operating system credentials. Which of the following should the tester use?
Correct Answer:
C
To further enumerate users on a Windows machine using native operating system commands, the tester should use net.exe commands. The net command is a versatile tool that provides various network functionalities, including user enumeration.
✑ net.exe: net user
✑ uk.co.certification.simulator.questionpool.PList@5192aa65 net localgroup administrators
✑ Enumerating Users:
✑ Pentest References:
Using net.exe commands, the penetration tester can effectively enumerate user accounts and group memberships on the compromised Windows machine, aiding in further exploitation and privilege escalation.

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:
A
To exploit a vulnerability in a wireless network's authentication mechanism and gain unauthorized access, the penetration tester would most likely perform a KARMA attack.
✑ KARMA Attack:
✑ Purpose:
✑ Other Options:
Pentest References:
✑ Wireless Security Assessments: Understanding common attack techniques such as KARMA is crucial for identifying and exploiting vulnerabilities in wireless networks.
✑ Rogue Access Points: Setting up rogue APs to capture credentials or perform man-in-the-middle attacks is a common tactic in wireless penetration testing.
By performing a KARMA attack, the penetration tester can exploit the wireless network's authentication mechanism and gain unauthorized access to the network.

While performing an internal assessment, a tester uses the following command: crackmapexec smb 192.168.1.0/24 -u user.txt -p Summer123@
Which of the following is the main purpose of the command?
Correct Answer:
C
The command crackmapexec smb 192.168.1.0/24 -u user.txt -p Summer123@ is used to perform password spraying on internal systems. CrackMapExec (CME) is a post- exploitation tool that helps automate the process of assessing large Active Directory
networks. It supports multiple protocols, including SMB, and can perform various actions like password spraying, command execution, and more.
✑ CrackMapExec:
✑ Command Breakdown:
✑ Password Spraying:
Pentest References:
✑ Password Spraying: An effective method for gaining initial access during penetration tests, particularly against organizations that have weak password policies or commonly used passwords.
✑ CrackMapExec: Widely used in penetration testing for its ability to automate and streamline the process of credential validation and exploitation across large networks.
By using the specified command, the tester performs a password spraying attack, attempting to log in with a common password across multiple usernames, identifying potential weak accounts.

During a penetration test, the tester identifies several unused services that are listening on all targeted internal laptops. Which of the following technical controls should the tester recommend to reduce the risk of compromise?
Correct Answer:
C
When a penetration tester identifies several unused services listening on targeted internal laptops, the most appropriate recommendation to reduce the risk of compromise is system hardening. Here's why:
✑ System Hardening:
✑ Comparison with Other Controls:
System hardening is the most direct control for reducing the risk posed by unused services, making it the best recommendation.
=================
A penetration tester plans to conduct reconnaissance during an engagement using readily available resources. Which of the following resources would most likely identify hardware and software being utilized by the client?
Correct Answer:
D
✑ Reconnaissance:
✑ Job Boards:
✑ Examples of Job Boards:
Pentest References:
✑ OSINT (Open Source Intelligence): Using publicly available sources to gather information about a target.
✑ Job boards are a key source of OSINT, providing indirect access to the internal technologies of a company.
✑ This information can be used to tailor subsequent phases of the penetration test, such as vulnerability scanning and exploitation, to the specific technologies identified.
By examining job boards, a penetration tester can gain insights into the hardware and software environments of the target, making this a valuable reconnaissance tool.
