Mastering Metasploit - Second Edition

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.

Preface

Globalizing variables in Metasploit


Working on a particular range or a specific host, we can always use the setg command to specify the LHOST and RHOST options. Setting the options with the setg command will set the RHOST or LHOST options globally for every module loaded. Hence, the setg command eliminates the use of setting up these specific options repeatedly. We can should make use of the setg command instead of options such as LPORT, RPORT, and payload. However, different services run on different ports and we may need to alter the payloads as well. Hence, setting up options that do not alter from one module to another is a better approach. Let's have a look at an example:

We assigned RHOST with setg command in the preceding screenshot. We can see that no matter how many times we change the module, the value of RHOST remains constant for all modules and we do not need to enter it manually in every module. The get command fetches the value of a variable from the current context, while...
