Overview of this book

Updated for the latest version of Metasploit, this book will prepare you to face everyday cyberattacks by simulating real-world scenarios. Complete with step-by-step explanations of essential concepts and practical examples, Mastering Metasploit will help you gain insights into programming Metasploit modules and carrying out exploitation, as well as building and porting various kinds of exploits in Metasploit. Giving you the ability to perform tests on different services, including databases, IoT, and mobile, this Metasploit book will help you get to grips with real-world, sophisticated scenarios where performing penetration tests is a challenge. You'll then learn a variety of methods and techniques to evade security controls deployed at a target's endpoint. As you advance, you’ll script automated attacks using CORTANA and Armitage to aid penetration testing by developing virtual bots and discover how you can add custom functionalities in Armitage. Following real-world case studies, this book will take you on a journey through client-side attacks using Metasploit and various scripts built on the Metasploit 5.0 framework. By the end of the book, you’ll have developed the skills you need to work confidently with efficient exploitation techniques

Evading intrusion detection systems with Metasploit

Your sessions on the target can be short-lived if an intrusion detection system is in place. Snort, a popular IDS system, can generate quick alerts when an anomaly is found on the network. Consider the following case of exploiting a Rejetto HFS server with a target with Snort IDS enabled:

Figure 9.25 – Snort detecting the Rejetto HFS exploit

Here, we can see that we successfully got the Meterpreter session. However, the image on the right suggests some priority one issues. I must admit that the rules created by the Snort team and the community are pretty strict and tough to bypass at times. However, to cover Metasploit evasion techniques as much as possible and for the sake of learning, we have created a simple rule to detect logins at the vulnerable HFS server, which is as follows:

alert tcp $EXTERNAL_NET any -> $HOME_NET $HTTP_PORTS (msg:"SERVER-WEBAPP Rejetto HttpFileServer Login attempt...
