However, despite its popularity and widespread use, many people are still not familiar with what Metasploit is, how it works, and its uses and benefits. This blog will provide an in-depth introduction to Metasploit, including its history, features, advantages and disadvantages, misconceptions, and frequently asked questions.

By the end of this blog, you will clearly understand what Metasploit is and how it can be used in security testing and assessment.

What is Metasploit?

The framework provided by the Metasploit open-source project can be used to test computer systems for security vulnerabilities. A wide variety of security and penetration tests can be performed on distributed target systems using the many different exploits collected in the framework.

Even the development of own exploits is possible. Furthermore, Metasploit can be misused to illegally penetrate a system. The framework is implemented in the Ruby programming language.

Metasploit can be installed on a wide variety of operating systems. These include Linux and Unix versions, macOS and Windows. In addition to command-line oriented input, graphical user interfaces are available for easier operation. The framework can be extended in various languages via add-ons. Metasploit is also part of the Linux distribution Kali Linux, which specializes in security tests.

The Metasploit framework

The Metasploit framework is modular and distinguishes between the tasks of developers and attackers. There is a separation between the attack methods (exploits) and the code to be executed. Exploits must be specifically tailored to the different vulnerabilities of software and hardware.

Code is used when an attack method has been successful and the system can be infiltrated or compromised. Other names for the code to be executed are shellcode or payload. Examples of shellcodes are command shells deployed on a special network port, reverse shells that independently establish a connection to the attacker system, reloadable and executable plugins or remote desktop software for targeted remote control of a computer such as VNC.

Thanks to the modularity of the framework, different payloads can be combined with arbitrary exploits. A special shellcode database contains the different payloads including source code that can be used by the framework.

To launch an attack, the following procedure is usually followed. First, the exploits that are to test the target system for security vulnerabilities are selected and configured. For example, the operating systems or the software and network applications used on the target system must be taken into account. Metasploit has several hundred different exploits available.

In the event of a successful attack, a payload must be selected to be executed on the target computer. The next step is to check whether the target device is vulnerable to a particular exploit. If this is the case, the system attempts to execute the desired payload. Using the various payloads, it is then possible to start further actions on the compromised computer system.

History of Metasploit

Metasploit is an open-source penetration testing framework that was created by HD Moore in 2003. The Metasploit Framework was originally written in Perl, but was later rewritten in Ruby. It was designed to simplify the process of exploiting vulnerabilities in networks, systems, and applications.

The original version of Metasploit, known as Metasploit 1.0, was released in October 2003. It was a simple command-line tool that included a handful of exploits and payloads. Over the years, the framework grew in popularity and functionality, and HD Moore formed a company, Metasploit LLC, in 2007 to develop and maintain the framework.

In 2009, Rapid7, a cybersecurity company, acquired Metasploit LLC and continued to develop and maintain the framework as an open-source project. In 2011, Metasploit became part of the Rapid7 product suite, and the company introduced a commercial version of the framework, known as Metasploit Pro, that included additional features and capabilities.

Today, Metasploit is widely used by security professionals, penetration testers, and hackers to identify and exploit vulnerabilities in systems and networks. The framework includes thousands of exploits, payloads, and modules that can be used to target a wide range of platforms and applications. Metasploit has also been integrated into a number of other security tools and platforms, making it an essential part of many security testing and assessment workflows.

How does Metasploit work?

Metasploit is a powerful penetration testing framework that allows security professionals and hackers to test the security of systems, networks, and applications by simulating attacks using known vulnerabilities. Here’s how Metasploit works:

  • Enumeration: The first step in using Metasploit is to identify the target system and its vulnerabilities. This is typically done through a process called enumeration, where the attacker gathers information about the target system, such as its operating system, installed software, network topology, and open ports.
  • Exploitation: Once the attacker has identified the target system’s vulnerabilities, they can use Metasploit to launch an attack against it. Metasploit provides a wide range of pre-built exploits that can be used to target known vulnerabilities in various operating systems, applications, and devices.
  • Payloads: When an exploit is successful, the attacker needs to deliver a payload to the target system. A payload is a piece of code that is executed on the target system, typically with the goal of establishing a remote command shell or creating a backdoor for further access.
  • Post-exploitation: Once a payload has been delivered to the target system, the attacker can use it to perform further actions, such as stealing sensitive data, modifying system settings, or launching additional attacks.
  • Reporting: Finally, after the penetration testing exercise is complete, Metasploit provides a range of reporting and analysis tools to help security professionals and hackers document their findings, identify areas of vulnerability, and recommend remediation measures.

Metasploit is a powerful and flexible tool that can be used for a wide range of security testing and assessment tasks, from simple vulnerability scanning to advanced penetration testing and ethical hacking.
