Penetration Testing Bootcamp

By: Jason Beltrame

Overview of this book

Penetration Testing Bootcamp delivers practical, learning modules in manageable chunks. Each chapter is delivered in a day, and each day builds your competency in Penetration Testing. This book will begin by taking you through the basics and show you how to set up and maintain the C&C Server. You will also understand how to scan for vulnerabilities and Metasploit, learn how to setup connectivity to a C&C server and maintain that connectivity for your intelligence gathering as well as offsite processing. Using TCPDump filters, you will gain understanding of the sniffing and spoofing traffic. This book will also teach you the importance of clearing up the tracks you leave behind after the penetration test and will show you how to build a report from all the data obtained from the penetration test. In totality, this book will equip you with instructions through rigorous tasks, practical callouts, and assignments to reinforce your understanding of penetration testing.

Summary


The challenge presented to me at the start of this chapter was to be able to create a secure tunnel to transfer our evidence offsite, while making sure we could get around any potential security devices. I also needed a way to get back into the environment from my C&C server without having the company create associated firewall access control rules and NAT rules.

Utilizing stunnel and reverse ssh, I was able to accomplish this. stunnel allowed me to have a SSL tunnel from the internal server to my external C&C server. The SSL tunnel is key since most firewalls will allow outbound SSL and most IPS setups will not decrypt the payload, and therefore it will go through without being inspected. The reverse ssh tunnel allowed the C&C server to piggyback off the already established ssh connection that originated from the inside server. Automating this allowed the entire setup to come back in the event of a reboot of the Raspberry Pi.

Using the script that I created, I was able...
