What Is Aircrack-ng?
Aircrack-ng is a powerful suite of tools used for auditing wireless networks. It focuses on Wi-Fi security, allowing users to monitor, attack, test, and crack wireless protocols—primarily WEP and WPA/WPA2-PSK.
It’s widely used by penetration testers, network administrators, and security researchers to assess the strength of wireless encryption and identify vulnerabilities.
Components of Aircrack-ng Suite
Aircrack-ng includes several tools, each with a specific function:
How Aircrack-ng Works
1. Enable Monitor Mode
Use airmon-ng to put your wireless adapter into monitor mode:
2. Capture Packets
Use airodump-ng to scan and capture packets:
You’ll see nearby networks, their encryption type, signal strength, and connected clients.

5. Crack the Key
Use aircrack-ng to crack the password using the .cap file:
Supported Encryption Types
