Open a new terminal and type command “ aircrack-ng wpacrack-01.cap -w /usr/share/dirb/wordlists/big.txt”. We will use the wordlist big.txt for cracking the password. This will show us a number of wordlists available by default in kali linux. So let’s find out where the dictionaries are.

#HOW TO USE AIRCRACK COMMANDS PASSWORD#

We will do dictionary password cracking here. Now let’s see where our capture file is located. We can see that a WPA handshake has happened in the previous terminal. As soon as this happens, all the clients will try to connect back to the wifi network once again. This will make all the clients connected to the shunya get disconnected.

This command will send 100 DE authentication packets to the broadcast address of the wifi access point.

is the MAC address of the wifi access point. –deauth are the deauthentication packets,ġ00 are the number of deauthentication packets we want to send.

Open a new terminal and type the command “ aireplay-ng –deauth 100 -a –ignore-negative-one mon0″. So let’s try to disconnect all the clients connected to the wifi network “shunya” first. We can only hack a WPA/WPA2 protected wifi network by capturing it’s handshake process or association( when the client is trying to connect to the wifi network.). Wpacrack is the file name we are writing into. c is used to specify the channel the wifi network is operating on. –bssid stands for base station security identifier Open a terminal and type command “ airodump-ng –bssid -c 13 –write wpacrack mon0″. We will collect the shunya’s network traffic into a file. We are going to hack the network “shunya”. We can see that all the wifi networks are configured with WPA2 or WPA. We can see all the wireless networks available as shown below. Now let’s see all the traffic collected by our wireless interface. We can see below that monitor mode has been enabled on “mon0″. Monitor mode is same as promiscuous mode in wired sniffing. Now we are going to start monitor mode on our wireless interface. We can see that we have a wireless interface wlan0. It lists your wireless interfaces just like ifconfig shows wired interfaces. Once you have booted into Kali Linux, open terminal and type command “ iwconfig”. I am running Kali Linux in live USB mode as my laptop has Atheros adapter. ( For this howto, if you are running Kali Linux in Vmware or Virtualbox you need to have a compatible wifi usb adapter). For this howto, I am going to use Kali Linux. So, today we are going to see WPA/WPA2 password cracking with aircrack. They are by far considered most secure for Wifi networks. Both can be configured to use counter cipher block chaining mode(CCM) though. The only difference between WPA and WPA2 is that they use Rivest Cipher(RC4) and Advanced Encryption Standard(AES) encryption algorithms respectively. Both WPA and WPA2 use temporal key integrity protocol(TKIP) for encryption and pre-shared key(PSK) authentication. WPA uses 128 bit key and 48 bit initialization vector while WEP uses 108 bit key with 24 bit initialization vector.

It eliminates all known vulnerabilities in WEP(Wired Equivalent Privacy). It is an encryption system to secure WLAN networks.
