Mastering Metasploit - Second Edition

By: Nipun Jaswal

Overview of this book

Metasploit is a popular penetration testing framework that has one of the largest exploit databases around. This book will show you exactly how to prepare yourself against the attacks you will face every day by simulating real-world possibilities. We start by reminding you about the basic functionalities of Metasploit and its use in the most traditional ways. You’ll get to know about the basics of programming Metasploit modules as a refresher, and then dive into carrying out exploitation as well building and porting exploits of various kinds in Metasploit. In the next section, you’ll develop the ability to perform testing on various services such as SCADA, databases, IoT, mobile, tablets, and many more services. After this training, we jump into real-world sophisticated scenarios where performing penetration tests are a challenge. With real-life case studies, we take you on a journey through client-side attacks using Metasploit and various scripts built on the Metasploit framework. By the end of the book, you will be trained specifically on time-saving techniques using Metasploit.

Testing VOIP services


Let's now focus on testing VOIP-enabled services and see how we can check for various flaws that might affect VOIP services.

VOIP fundamentals

Voice Over Internet Protocol (VOIP) is a much less costly technology when compared to the traditional telephonic services. VOIP provides much more flexibility than the traditional ones in terms of telecommunication and offers various features, such as multiple extensions, caller ID services, logging, recording of each call made, and so on. Various companies have launched their Private Branch eXchange (PBX) on IP-enabled phones.

The traditional and the present telephonic systems are still vulnerable to interception through physical access, so that if an attacker alters the connection of a phone line and attaches their transmitter, they will be able to make and receive calls to the victim's device and enjoy Internet and fax services.

However, in the case of VOIP services, we can compromise security without going on to the wires. Nevertheless...
