Mastering Metasploit - Third Edition

By: Nipun Jaswal

Overview of this book

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 databases, Cloud environment, IoT, mobile, tablets, and similar 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

Now, let's 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 traditional telephonic services. VOIP provides much more flexibility than the traditional ones regarding telecommunication and offers various features, such as multiple extensions, caller ID services, logging, recording of each call made, and so on. Multiple 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 if an attacker alters...
