You’ve probably heard of Metasploit before, but what is it? Simply put, it’s a tool used by hackers to exploit vulnerabilities in systems. But it’s more than that; the Metasploit project is a framework that allows you to create custom exploits and payloads for attacking systems. It’s widely used because it’s reliable and easy to use.
What is Metasploit, and What does it do?

The Metasploit exploit development framework is a Ruby-based open-source project that allows you to create custom exploits and payloads. Metasploit modules are easy to use and extend, which makes them a popular choice for ethical hackers and penetration testers. This open-source framework can be used to test for software vulnerabilities on networks and servers, and once flaws are identified, the information can be used to address systemic weaknesses.
Metasploit is a powerful tool, but it’s important to remember that it can be used for good and evil. Cybercriminals can use the framework to launch attacks, so it’s essential to be aware of the risks involved in using Metasploit. However, as an ethical hacker or penetration tester, Metasploit can be an essential tool for helping to secure systems.
How Metasploit Works
Metasploit works with various testing tools, including Nmap, SNMP scanning, windows patch enumeration, and even post-exploitation tools. It works by exploiting vulnerabilities in the target machine. It does this by using payloads from exploit modules, which are simple scripts that the cybersecurity professional utilizes to interact with a hacked system. Using payloads, they can transfer data to a victim machine.
Metasploit payloads can be of three types − singles, staged, and stages.
- Singles are very small and designed to create some communication, then move to the next stage. For example, just creating a user.
- Staged is a payload that an attacker can use to upload a bigger file onto a victim system.
- Stages are payload components that are downloaded by stagers modules. The various payload stages provide advanced features with no size limits, such as Meterpreter and VNC Injection.
If one is exploiting a target system:
- The first step is to select the payload you want to use from Metasploit Console. The options include exploits, shellcodes, and encoders.
- Next, you need to select the target machine. This can be a browser, email client, or system.
- Finally, you need to enter the host IP address and port number.
- Once you have entered all the information, click on “Launch,” and Metasploit will do the rest.
Not only for exploiting, but Metasploit components also have scanning, fuzzing, and sniffing scripts that can help one find potential victims. These are called auxiliary modules, and they give a deeper understanding of the target system from various tasks such as port scanning and fingerprinting, identifying services, and even launching denial of service attacks.
The Benefits of Using Metasploit
While the benefits of using Metasploit are many, It is important to remember that the Metasploit framework is a powerful exploitation tool and should be used for legitimate purposes only. Misuse of Metasploit commands can result in system instability or even data loss.
Here are some top benefits of using Metasploit Exploit Modules:
- Metasploit Framework is open source, which makes it freely available to everyone.
- Metasploit supports large testing networks by making use of CIDR identifiers.
- Metasploit offers a quick generation of payloads that can be changed or switched on the fly.
- Metasploit leaves the target system stable in most cases.
- The GUI environment provides a fast and user-friendly way to conduct penetration testing.
- Metasploit has a substantial active community that contributes to its development.
- Metasploit is regularly and actively developed with new updates, features, and modules.
- Penetration testers can use Metasploit to exploit vulnerabilities and conduct security assessments.
- The Metasploit interface allows users to develop and test their own exploits.
- Metasploit is the most popular penetration testing toolkit in the world.
How to Get Metasploit?
To get Metasploit, you can download the installer from the Rapid7 website. Visit https://www.rapid7.com/products/metasploit/download.jsp to find and download the installer for various operating systems.
Once you have downloaded the installer, you have to enter the destination folder where you want to Install Metasploit.
Kali Linux:
If you’re a Kali Linux 2.0 user, you’re in luck – the Metasploit Framework is pre-installed and updated monthly. But if you want to get updates more frequently, you can use this installer or use apt-get from your command line interface.
For Windows Systems:
- Visit http://windows.metasploit.com/metasploitframework-latest.msi to download the Windows installer. After downloading the installer, double-click the icon to start the installation process.
- When the Setup screen appears, click Next to continue. Please read the license agreement and select the I accept the license agreement option. Click Next to continue.
- Browse to the location where you want to install the Metasploit Framework. By default, the framework is installed on C:\Metasploit-framework. Click Next to continue.
- Click Install. The installation process can take 5-10 minutes to complete. When it’s done, click Finish.
How Does Metasploit Framework Help in Penetration Testing?
In penetration testing, Metasploit can be used to launch an exploit against a system to test its security. For example, if you have found a vulnerability in a web server and want to try whether it can be exploited, you can use Metasploit to launch an attack. If the attack is successful, Metasploit will provide you with a shell on the target system where you can run commands and access sensitive information.
Metasploit can also be used for social engineering attacks. For example, if you want to trick someone into running a malicious program on their computer, you could create a fake website that looks like a legitimate site and host it on your server. When the victim visits the site and clicks on a link, they will be redirected to your server, and the malicious program will be downloaded and executed on their computer.
Metasploit can also be used to conduct denial of service attacks. In a denial of service attack, the attacker tries to prevent legitimate users from accessing a system by flooding it with requests that overload the server and prevents it from responding to genuine requests.
Conclusion
Metasploit is a powerful tool that can be used for penetration testing and vulnerability assessment. It can be used to launch exploits against systems to test their security. It can also be used as a vulnerability research tool to find and fix a metasploitable machine and evade detection.
