The Complete Metasploit Guide

By: Sagar Rahalkar, Nipun Jaswal

Overview of this book

Most businesses today are driven by their IT infrastructure, and the tiniest crack in this IT network can bring down the entire business. Metasploit is a pentesting network that can validate your system by performing elaborate penetration tests using the Metasploit Framework to secure your infrastructure. This Learning Path introduces you to the basic functionalities and applications of Metasploit. Throughout this book, you’ll learn different techniques for programming Metasploit modules to validate services such as databases, fingerprinting, and scanning. You’ll get to grips with post exploitation and write quick scripts to gather information from exploited systems. As you progress, you’ll delve into real-world scenarios where performing penetration tests are a challenge. With the help of these case studies, you’ll explore client-side attacks using Metasploit and a variety of scripts built on the Metasploit Framework. By the end of this Learning Path, you’ll have the skills required to identify system vulnerabilities by using thorough testing. This Learning Path includes content from the following Packt products: Metasploit for Beginners by Sagar Rahalkar Mastering Metasploit - Third Edition by Nipun Jaswal

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:

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, for the maximum coverage of Metasploit evasion techniques 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...
