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

Using encoders to avoid AV detection

In Chapter 6, Client-side Attacks with Metasploit, we have already seen how to use the msfvenom utility to generate various payloads. However, these payloads if used as-is are most likely to be detected by antivirus programs. In order to avoid antivirus detection of our payload, we need to use encoders offered by the msfvenom utility. 

To get started, we'll generate a simple payload in the .exe format using the shikata_ga_nai encoder, as shown in the following screenshot:

Once the payload has been generated, we upload it to the site http://www.virustotal.com for analysis. As the analysis is completed, we can see that our file apache-update.exe (containing a payload) was detected by 46 out of the 60 antivirus programs that were used. This is quite a high detection rate for our payload. Sending this payload as-is...
