By hearing every packet, we can later capture the WPA/WPA2 4-way handshake.
There is a small dictionary that comes with aircrack-ng -.
Aircrack-ng.2 beta300:01: keys tested (1017.96 k/s)KEY found!This can change channels and/or aircrack change mode without your knowledge.If you use the deauth technique, send the absolute minimum of packets to cause the client to reauthenticate.Hccap to this folder and type: cd also I copied crack my dictionary to the same folder.The cracked password handshake will be saved to hackme.Hashcat is world's fastest password cracker, it is multi-OS (Linux, Windows and OSX so if you have some nasty problems with proprietary drivers for GPU on Linux or just feel more comfortable aircrack inside Windows you can crack Wi-Fi password on it!Open another console session handshake and enter: aireplay-ng -0 1 -a 00:14:6C:7E:40:80 -c 00:0F:B5:FD:FB:C2 ath0 Where: -0 means deauthentication 1 is the number of deauths to send (you can send multiple if you wish) aircrack -a 00:14:6C:7E:40:80 is the MAC address of the access handshake point -c 00:0F:B5:FD:FB:C2.

The point is, if you don't get it the first time, have patience and experiment a bit.
We will use the aireplay-ng command to send fake deauth crack packets to our victim client, forcing it to reconnect to the network and hopefully grabbing a handshake in the process.
Dont be a dick.
Bssid (MAC address of access point 00:14:6C:7E:40:80.It can be done!A USB Wi-Fi Adapter setup which supports monitor mode.To match the frequency studio to the channel, check out: ml#wp134132.The exact procedure for enabling monitor mode varies depending on the driver you are using.The system will respond: Interface Chipset Driver wifi0 Atheros madwifi-ng ath0 Atheros madwifi-ng VAP (parent: wifi0) (monitor mode enabled) You will notice that manual ath0 is reported above as being put into monitor mode.You only perform this step if you opted to actively speed up the process.Unlike madwifi-ng, you do not need to remove the wlan0 interface when setting up mac80211 drivers.Start listening to 802.11 Beacon frames broadcast by nearby wireless routers using your monitor interface by typing airodump-ng wlan0mon in your same terminal.Remember that just because you can receive packets from them does not mean you may will be able to transmit packets to them.If you are thinking about generating your own password list manual to cover all the permutations and combinations of characters iogear and special symbols, check out this brute force time calculator first.Capture a 4-way Handshake WPA/WPA2 uses a 4-way handshake to authenticate devices tutorials to the network.That is, because the key is not static, so collecting IVs like when cracking WEP encryption, does not speed up the attack.
