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.
