A penetration tester needs to complete cleanup activities from the testing lead. Which of the following should the tester do to validate that reverse shell payloads are no longer running?

A. Run scripts to terminate the implant on affected hosts.

B. Spin down the C2 listeners.

C. Restore the firewall settings of the original affected hosts.

D. Exit from C2 listener active sessions.

A. Run scripts to terminate the implant on affected hosts.

To ensure that reverse shell payloads are no longer running, it is essential to actively terminate any implanted malware or scripts. Here’s why option A is correct:

Run Scripts to Terminate the Implant: This ensures that any reverse shell payloads or malicious implants are actively terminated on the affected hosts. It is a direct and effective method to clean up after a penetration test.

Spin Down the C2 Listeners: This stops the command and control listeners but does not remove the implants from the hosts.

Restore the Firewall Settings: This is important for network security but does not directly address the termination of active implants.

Exit from C2 Listener Active Sessions: This closes the current sessions but does not ensure that implants are terminated.

References from Pentest:

Anubis HTB: Demonstrates the process of cleaning up and ensuring that all implants are removed after an assessment.

Forge HTB: Highlights the importance of thoroughly cleaning up and terminating any payloads or implants to leave the environment secure post-assessment.

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?

A. OS fingerprinting

B. Attack path mapping

C. Service discovery

D. User enumeration

C. Service discovery

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.

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?

A. route.exe print

B. netstat.exe -ntp

C. net.exe commands

D. strings.exe -a

C. net.exe commands

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.

Explanation:

net.exe: net user uk.co.certification.simulator.questionpool.PList@a43cf82 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.

A penetration tester has found a web application that is running on a cloud virtual machine instance. Vulnerability scans show a potential SSRF for the same application URL path with an injectable parameter. Which of the following commands should the tester run to successfully test for secrets exposure exploitability?

A. curl <url>?param=http://169.254.169.254/latest/meta-data/

B. curl '<url>?param=http://127.0.0.1/etc/passwd'

C. curl '<url>?param=<script>alert(1)<script>/'

D. curl <url>?param=http://127.0.0.1/

A. curl <url>?param=http://169.254.169.254/latest/meta-data/

In a cloud environment, testing for Server-Side Request Forgery (SSRF) vulnerabilities involves attempting to access metadata services. Here’s why the specified command is appropriate:

Accessing Cloud Metadata Service:

Comparison with Other Commands:

Using curl <url>?param=http://169.254.169.254/latest/meta-data/ is the correct approach to test for SSRF vulnerabilities in cloud environments to potentially expose secrets.

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?

A. Cryptographic flaws

B. Protocol scanning

C. Cached pages

D. Job boards

To conduct reconnaissance and identify hardware and software used by a client, job boards are an effective resource. Companies often list the technologies they use in job postings to attract qualified candidates. These listings can provide valuable insights into the specific hardware and software platforms the client is utilizing.

Explanation:

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.
