Kali Linux Intrusion and Exploitation Cookbook

By: Dhruv Shah, Ishan Girdhar

Overview of this book

With the increasing threats of breaches and attacks on critical infrastructure, system administrators and architects can use Kali Linux 2.0 to ensure their infrastructure is secure by finding out known vulnerabilities and safeguarding their infrastructure against unknown vulnerabilities. This practical cookbook-style guide contains chapters carefully structured in three phases – information gathering, vulnerability assessment, and penetration testing for the web, and wired and wireless networks. It's an ideal reference guide if you’re looking for a solution to a specific problem or learning how to use a tool. We provide hands-on examples of powerful tools/scripts designed for exploitation. In the final section, we cover various tools you can use during testing, and we help you create in-depth reports to impress management. We provide system engineers with steps to reproduce issues and fix them.

Preface

Determining the OS using nmap and xprobe2


In this recipe, we will be using tools to what kind of system the target IP is running on. Mapping a target IP with a operating system is necessary to help shortlist and verify vulnerabilities.

Getting ready

In this recipe, we will use the tool to determine the operating system. All we require is an IP address against which we will run the OS enumeration scan. Others tools that can be used are hping and xprobe2.

How to do it...

Let begin by the system:

  1. Open and type the following:
nmap -O <IP address>

The output will be as shown in the following screenshot:

We can use advanced operators to help us find out the operating system in a more aggressive manner. Type the following command in terminal:

nmap O --osscan-guess <IP address>

The will as in the screenshot:

This shows that using additional parameters of the operating system detection in nmap, we can get a probable idea of the best fit.

  1. Xprobe2 uses a different to nmap...
