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.

Understanding an evil twin attack


An evil twin attack is a type of Wi-Fi attack where a rogue Wi-Fi access point (AP) is used to mimic a legitimate access point provided by a business, such as a coffee shop that offers free Wi-Fi access to its customers.

By imitating a legitimate access point, we can trick users into connecting to it, so we can steal credentials, redirect victims to malware sites, perform LLMNR, NBT-NS poisoning attacks, and so on.

Getting ready

We will start by installing a DHCP server todynamically configure the victim's IP setting:

apt install isc-dhcp-server -y

Next, configure the DHCP server by editing the configuration file at /etc/dhcp/dhcpd.conf:

authoritative;
default-lease-time 600;
max-lease-time 7200;
subnet 10.0.0.0 netmask 255.255.255.0
{
        option subnet-mask 255.255.255.0;
        option broadcast-address 10.0.0.255;
        option routers 10.0.0.1;
        option domain-name-servers 8.8.8.8;
        range 10.0.0.100 10.0.0.254;
}

How to do it...

Now that we...
