Metasploit 5.0 for Beginners - Second Edition

By: Sagar Rahalkar

Overview of this book

Securing an IT environment can be challenging, however, effective penetration testing and threat identification can make all the difference. This book will help you learn how to use the Metasploit Framework optimally for comprehensive penetration testing. Complete with hands-on tutorials and case studies, this updated second edition will teach you the basics of the Metasploit Framework along with its functionalities. You’ll learn how to set up and configure Metasploit on various platforms to create a virtual test environment. Next, you’ll get hands-on with the essential tools. As you progress, you’ll learn how to find weaknesses in the target system and hunt for vulnerabilities using Metasploit and its supporting tools and components. Later, you'll get to grips with web app security scanning, bypassing anti-virus, and post-compromise methods for clearing traces on the target system. The concluding chapters will take you through real-world case studies and scenarios that will help you apply the knowledge you’ve gained to ethically hack into target systems. You’ll also discover the latest security techniques that can be directly applied to scan, test, ethically hack, and secure networks and systems with Metasploit. By the end of this book, you’ll have learned how to use the Metasploit 5.0 Framework to exploit real-world vulnerabilities.

Understanding the need for client-side attacks

In the previous chapter, we used the MS08_067net api vulnerability in our target system to gain complete administrator-level access to the system. We configured the value of the RHOST variable as the IP address of our target system. Now, the exploit was successful only because the attacker's system and the target system were both on the same network (the IP address of the attacker's system was 192.168.44.134 and the IP address of the target system was 192.168.44.129).

This scenario was pretty straightforward, as shown here:

Figure 6.1 – Attack Scenario

Now consider the scenario shown in the following figure. The IP address of the attacker's system is a public address, and he is trying to exploit a vulnerability on a system that is not in the same network. Note that the target system, in this case, has a private IP address (10.11.1.56) and is NATed behind an internet router (88.43.21.9x...
