Hack Wi-Fi Passwords with Metasploit: A Complete Guide to Penetration Testing

Introduction to Metasploit for Hacking Wi-Fi Passwords

As technology continues to advance, the need for internet connectivity grows more significant than ever. Wi-Fi networks have become a staple in our daily routine, and the need to protect them from malicious attacks is paramount.

Password protection is the usual security measure used to prevent unauthorized access to Wi-Fi networks. However, password-protected networks are not always secure, and hackers have exploited vulnerabilities to gain access.

Metasploit is a powerful penetration testing platform that provides cybersecurity experts with tools to scan, exploit, and penetrate vulnerabilities in a network. This article will introduce you to Metasploit, explain how it is used to hack Wi-Fi passwords, and provide instructions for using Metasploit to hack Wi-Fi passwords.

Overview of Metasploit as a Penetration Testing Platform

Metasploit is a penetration testing framework, written in Ruby, that enables cybersecurity professionals to simulate attacks on a network. It was developed in 2003 by H.D. Moore, who is currently the chief research officer at Rumble Network Discovery.

Metasploit consists of several modules, which are categorized into exploits, payloads, and auxiliary modules. Exploits are used to identify and exploit security vulnerabilities in software, while payloads are the scripts that are executed after an exploit is successful.

Auxiliary modules consist of tools for information gathering that support the execution of exploits and payloads. Metasploit is an open-source project and has a community of developers constantly updating and improving its modules.

Description of John the Ripper and Its Use in Metasploit

John the Ripper is a free password-cracking software used to identify weak passwords. It is one of the many tools present in Metasploit and is a popular password-cracking software that can be used to audit the strength of passwords.

John the Ripper can crack over 200 passwords in a minute and uses multiple techniques, such as dictionary attacks and brute force attacks, to crack passwords. It works by generating a list of possible passwords and testing them against the encrypted hash values stored in the system.

John the Ripper provides cybersecurity experts with valuable insights into the weaknesses of a network’s password security.

Possibility of Hacking Wi-Fi Passwords With Metasploit and Categorization of Wi-Fi Security Measures

Hackers can use Metasploit to hack into Wi-Fi networks and steal sensitive information. Wi-Fi security protocols are divided into three categories, WEP, WPA, and WPA2, based on the level of security they offer.

The first category, WEP, is regarded as the weakest security protocol as it can easily be hacked and is no longer recommended. WPA is more secure than WEP but can still be hacked using a dictionary or brute force attack.

WPA2 is the most secure Wi-Fi security protocol and offers robust protection against cyber attacks. However, WPA2 security can still be breached using a malicious software program like Metasploit.

Overview of

msfconsole for Managing Metasploit Database, Connections, and Module Configuration

Msconsole is the primary interface used to manage Metasploit modules, database, and network connections. It is also used to configure Metasploit settings and

run exploits. Msfconsole is not only user-friendly but also helps to automate the execution of tasks.

One can use

msfconsole to initialize Metasploit database, scan and enumerate targets, exploit vulnerabilities, and use post-exploitation modules.

Description of psnuffle as a Metasploit Password-Sniffing Component

Psnuffle is a powerful tool included in Metasploit’s auxiliary module and used to sniff for plain-text passwords in a network. It works by intercepting traffic that passes through a network and searching for plain-text passwords.

It requires that ARP Poisoning is implemented in the network to redirect the traffic to the attacker’s machine. Once the traffic is redirected, psnuffle detects sensitive information, including credentials, plaintext usernames, and other sensitive data.

Psnuffle is an excellent tool for cybersecurity professionals to use when testing the strength of Wi-Fi networks.


In conclusion, Wi-Fi networks are essential in our daily routine, and the security measures put in place must be robust and effective in protecting against cyber attacks. This article has introduced Metasploit, described how it is used to hack Wi-Fi passwords, and provided instructions for using Metasploit to hack Wi-Fi passwords.

Remember, hacking into any network without permission is a crime, and it is essential to use Metasploit for penetration testing purposes only.

Hacking Wi-Fi Passwords with Metasploit

In this article, we will delve deeper into the use of Metasploit to hack Wi-Fi passwords. We will specifically explore the option to import pcap capture files, instructions for using the default settings for psnuffle scanner and emphasize the understanding of hacking concepts in thorough explanation of the method to hack Wi-Fi passwords in Metasploit.

Explanation of the Option to Import Pcap Capture Files

Pcap (Packet Capture) files contain network traffic data that can be captured using a network analyzer tool. Metasploit provides an option to import pcap files to analyze network traffic data and identify potential vulnerabilities in a network.

This feature enables a cybersecurity professional to simulate an attack by importing a network traffic packet capture file from previously recorded scan results. To import a pcap file, follow these steps:

Step 1: Open Metasploit and access the by

running the

msfconsole command:




Step 2: Run the following command to import the pcap file into Metasploit:


db_import /path/to/pcap/file.pcap


Once the import is complete, cyber security professionals can begin to analyze the file and search for vulnerabilities in the Wi-Fi network.

Instructions for Using the Default Settings for Psnuffle Scanner

Psnuffle is one of the most powerful password-sniffing components of Metasploit. It is an excellent tool for identifying network traffic and searching for plaintext passwords.

Although psnuffle has several configuration options, using the default settings can be sufficient for most cases. Here is how to use psnuffle with default settings:

Step 1: Open





Step 2: Search for psnuffle using the following command:


search name:psnuffle


Step 3: Load psnuffle into Metasploit with the following command:


use auxiliary/sniffer/psnuffle


Step 4: Configure the network interface to use by

running the following command and replacing INTERFACE with the name of your network interface:


set INTERFACE your_interface_name


Step 5: Finally,

run the psnuffle scanner with the following command:




Once the psnuffle scanner has completed, it will provide an output of any plaintext usernames and passwords found.

Emphasizing Understanding of Hacking Concepts and Thorough Explanation of Method to Hack Wi-Fi Passwords in Metasploit

It is vital to emphasize that only authorized cybersecurity professionals should use Metasploit to hack Wi-Fi passwords for penetration testing purposes. The unauthorized use of Metasploit is a crime and can lead to severe legal consequences.

To use Metasploit to hack into Wi-Fi passwords, follow these steps:

Step 1: You can leverage the airmon-ng utility to list the Wi-Fi networks in range:


sudo airmon-ng


Step 2: Put your wireless card into monitor mode:


sudo airmon-ng start wlan0


Step 3: Scan for all active Wi-Fi networks using the following command:


sudo airodump-ng wlan0mon


Step 4: Identify the Wi-Fi network you want to target and take note of the BSSID and channel numbers. Step 5: Select and capture the packets of the targeted Wi-Fi network:


sudo airodump-ng channel [CHANNEL#] bssid [BSSID] write [FILENAME] wlan0mon


Step 6: Now, use Wireshark to extract packets as a pcap format file.

Follow these steps:

Open the Wireshark application

Click on “Open” and select the capture file to analyze. Choose ‘Export specified packets’ and select ‘As a single pcap file’

Save the captured packets in pcap format.

Step 7: Import the captured packets file into Metasploit through the db_import command:


db_import /path/to/captured_files.pcap


Step 8: Load the psnuffle scanner and set the network interface before



use auxiliary/sniffer/psnuffle

set interface “your_network_interface_name”




In conclusion, the use of Metasploit in hacking Wi-Fi passwords is a useful tool for penetration testing purposes.
