The Metasploit Framework is one of the most popular and powerful tools used in penetration testing. It provides a comprehensive platform for developing, testing, and executing exploits against various systems. This module will cover the basics of Metasploit, its components, and how to use it effectively in penetration testing.

What is Metasploit?

Metasploit is an open-source framework that allows security professionals to identify, exploit, and validate vulnerabilities in systems. It includes a vast library of exploits, payloads, and auxiliary modules that can be used to perform various penetration testing tasks.

Key Features of Metasploit:

Exploit Modules: Pre-written code that takes advantage of vulnerabilities in software.
Payloads: Code that runs on the target system after exploitation.
Auxiliary Modules: Tools for scanning, fuzzing, and other tasks.
Post-Exploitation Modules: Tools for maintaining access and gathering information after exploitation.

Installing Metasploit

Metasploit can be installed on various operating systems, but it is most commonly used on Kali Linux. Here are the steps to install Metasploit on Kali Linux:

# Update the package list
sudo apt-get update

# Install Metasploit
sudo apt-get install metasploit-framework

Basic Usage of Metasploit

Starting Metasploit

To start Metasploit, open a terminal and type:

msfconsole

This command will launch the Metasploit console, which is the primary interface for interacting with the framework.

Searching for Exploits

You can search for exploits using the search command. For example, to search for exploits related to Apache, you can use:

search apache

Using an Exploit

Once you have identified an exploit, you can use it with the use command. For example, to use an Apache exploit, you might type:

use exploit/unix/webapp/apache_mod_cgi_bash_env_exec

Setting Options

After selecting an exploit, you need to set various options, such as the target IP address. You can view the required options with the show options command:

show options

To set an option, use the set command. For example, to set the target IP address:

set RHOSTS 192.168.1.100

Running the Exploit

Once all options are set, you can run the exploit with the run or exploit command:

run

Practical Example

Let's walk through a practical example of exploiting a vulnerable FTP server.

Step 1: Search for FTP Exploits

search ftp

Step 2: Select an Exploit

use exploit/unix/ftp/vsftpd_234_backdoor

Step 3: Set Options

set RHOSTS 192.168.1.100

Step 4: Run the Exploit

run

If the exploit is successful, you will gain access to the target system.

Practical Exercises

Exercise 1: Exploiting a Vulnerable Web Application

Search for Web Exploits: Use the search command to find exploits related to web applications.
Select an Exploit: Choose an appropriate exploit from the search results.
Set Options: Configure the necessary options, such as the target IP address and port.
Run the Exploit: Execute the exploit and observe the results.

Exercise 2: Post-Exploitation Activities

Gain Access: Use an exploit to gain access to a target system.
Use Post-Exploitation Modules: Explore the available post-exploitation modules and use them to gather information or maintain access.

Common Mistakes and Tips

Incorrect Options: Ensure that all required options are set correctly before running an exploit.
Outdated Exploits: Some exploits may not work on updated systems. Always verify the target's software version.
Network Configuration: Ensure that your network configuration allows communication between your machine and the target.

Conclusion

The Metasploit Framework is an essential tool for penetration testers, providing a wide range of capabilities for exploiting and validating vulnerabilities. By understanding how to use Metasploit effectively, you can significantly enhance your penetration testing skills. In the next module, we will explore another powerful tool, OWASP ZAP, which is used for web application security testing.
