AIRCRACK-NG

A complete suite of tools to assess WiFi network security

What is Aircrack-NG?

Aircrack-NG is a powerful network software suite consisting of a detector, packet sniffer, WEP and WPA/WPA2-PSK cracker and analysis tool for 802.11 wireless LANs. It focuses on different areas of WiFi security:

Monitoring Attacking Testing Cracking

Key Features

Monitoring: Packet capture and export of data to text files for further processing
Attacking: Replay attacks, deauthentication, fake access points
Testing: Checking WiFi cards and driver capabilities
Cracking: WEP and WPA PSK (WPA 1 and 2)

Core Tools

airmon-ng - Sets wireless cards to monitor mode
airodump-ng - Packet capture program
aireplay-ng - Packet injection program
aircrack-ng - WEP and WPA/WPA2-PSK key cracking program

Basic Usage

First, you need to put your wireless adapter into monitor mode:

$ sudo airmon-ng start wlan0

This creates a monitoring interface (typically wlan0mon or similar).

Once your card is in monitor mode, you can scan for wireless networks:

$ sudo airodump-ng wlan0mon

This displays all wireless networks in range along with connected clients.

To capture a WPA handshake from a specific network:

$ sudo airodump-ng -c [channel] --bssid [target MAC] -w [output file] wlan0mon

You'll need to wait for a client to connect or use deauthentication to force a reconnection.

After capturing a handshake, you can attempt to crack the password:

$ sudo aircrack-ng -w [wordlist path] -b [target MAC] [capture file]*.cap

The success rate depends on the password complexity and your wordlist quality.

Legal and Ethical Considerations

⚠️ WARNING: Using Aircrack-NG to access networks without explicit authorisation is illegal in most jurisdictions. Always:

Only test networks you own or have explicit permission to test
Use in a controlled lab environment for learning
Be aware of relevant laws and regulations in your area
Consider the ethical implications of security testing
