A penetration tester is getting ready to conduct a vulnerability scan as part of the testing process. The tester will evaluate an environment that consists of a container orchestration cluster. Which of the following tools should the tester use to evaluate the cluster?
Correct Answer:D
Evaluating a container orchestration cluster, such as Kubernetes, requires specialized tools designed to assess the security and configuration of container environments. Here??s an analysis of each tool and why Kube-hunter is the best choice:
✑ Trivy (Option A):
✑ Nessus (Option B):
✑ Grype (Option C):
✑ Kube-hunter (Answer: D):
Conclusion: Kube-hunter is the most appropriate tool for evaluating a container orchestration cluster, such as Kubernetes, due to its specialized focus on identifying security vulnerabilities and misconfigurations specific to such environments.

Using the output, identify potential attack vectors that should be further investigated.
Solution:
1: Null session enumeration Weak SMB file permissions Fragmentation attack
2: nmap

-p 1-1023
: 192.168.2.2
3: #!/usr/bin/python export $PORTS = 21,22 for $PORT in $PORTS: try:
s.connect((ip, port))
print(??%s:%s – OPEN?? % (ip, port)) except socket.timeout
print(??%:%s – TIMEOUT?? % (ip, port)) except socket.error as e:
print(??%:%s – CLOSED?? % (ip, port)) finally
s.close() port_scan(sys.argv[1], ports)
Does this meet the goal?
Correct Answer:A
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?
Correct Answer:D
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:
✑ Solution: DOMAINS_LIST="/path/to/list.txt" while read -r i; do
nikto -h $i -o scan-$i.txt & done < "$DOMAINS_LIST"

A penetration tester performs an assessment on the target company's Kubernetes cluster using kube-hunter. Which of the following types of vulnerabilities could be detected with the tool?
Correct Answer:B
kube-hunter is a tool designed to perform security assessments on Kubernetes clusters. It identifies various vulnerabilities, focusing on weaknesses and misconfigurations. Here??s why option B is correct:
✑ Kube-hunter: It scans Kubernetes clusters to identify security issues, such as
misconfigurations, insecure settings, and potential attack vectors.
✑ Network Configuration Errors: While kube-hunter might identify some network- related issues, its primary focus is on Kubernetes-specific vulnerabilities and misconfigurations.
✑ Application Deployment Issues: These are more related to the applications running within the cluster, not the cluster configuration itself.
✑ Security Vulnerabilities in Docker Containers: Kube-hunter focuses on the Kubernetes environment rather than Docker container-specific vulnerabilities.
References from Pentest:
✑ Forge HTB: Highlights the use of specialized tools to identify misconfigurations in environments, similar to how kube-hunter operates within Kubernetes clusters.
✑ Anubis HTB: Demonstrates the importance of identifying and fixing misconfigurations within complex environments like Kubernetes clusters.
Conclusion:
Option B, weaknesses and misconfigurations in the Kubernetes cluster, accurately describes the type of vulnerabilities that kube-hunter is designed to detect.

A penetration tester is conducting reconnaissance on a target network. The tester runs the following Nmap command: nmap -sv -sT -p - 192.168.1.0/24. Which of the following
describes the most likely purpose of this scan?
Correct Answer:C
The Nmap command nmap -sv -sT -p- 192.168.1.0/24 is designed to discover services on a network. Here is a breakdown of the command and its purpose:
✑ Command Breakdown:
✑ Purpose of the Scan:
Conclusion: The nmap -sv -sT -p- 192.168.1.0/24 command is most likely used for service discovery, as it aims to identify all running services and their versions on the target subnet.
