Wpa2-psk crack backtrack

Enter the following command in terminal: It will show you the output like this: Using the above methods, you should have known the encryption-type of targeted WiFi network which you want to hack. It will show you what network interface are you using. In my system, I have only one network interface card wlan0 , which is my wireless interface card.

Create a network interface which runs in monitor mode. To do this enter command airmon-ng start wlan0. Make sure to replace wlan0 in command with the interface name that your card have. Here, mon0 has been created. Now, you might or might not get the warning appearing in the below screenshot which tells other processes using the network which can create the problem. So, you can kill them using the syntax: kill PID if you know those processes are not important for you at the moment.

It can take time to all the available WiFi networks in range. First enter the command airplay-ng -1 0 -a FB:A9:B1 mon0 to perform fake authentication -1 in command to the network. Hit enter and the command will start doing attack to WEP WiFi Access point and you can see the Data value increasing at enormously fast rate. In below screenshot the bell Once you have enough data in the file bell It will test all the data values available in key file and automatically show you the key it found by testing data in file.

You can see in above screenshot that we have successfully cracked the password of targeted WEP WiFi network The key found will not be in those text or alphanumeric format that the WiFi owner has created.

In backtrack4, this device is recognized as wlan0. At this point, you have 2 options : either wait until a client connects and the 4-way handshake is complete, or deauthenticate an existing client and thus force it to reassociate.

We need the bssid of the AP -a and the mac of a connected client -c. Form this point forward, you do not need to be anywhere near the wireless network. All cracking will happen offline, so you can stop airodump and other processes and even walk away from the AP.

In fact, I would suggest to walk away and find yourself a cosy place where you can live, eat, sleep, etc…. There are 2 ways of bruteforcing : one that is relatively fast but does not guarantee success and one that is very slow, but guarantees that you will find the key at some point in time.

A lot of these files can be found on the internet e. Once the wordlist is created, all you need to do is run aircrack-ng with the worklist and feed it the. Note : the PSK in my testlab is only 8 characters, contains one uppercase character and 4 numbers. I will post the output when the key was cracked, including the time it required to crack the key. Update :after 20 hours of cracking, the key still has not been found. All rights reserved. Do you like our free content?

Corona-proof, of course! The second method bruteforcing will be successfull for sure, but it may take ages to complete. Keep in mind, a WPA2 key can be up to 64 characters, so in theory you would to build every password combination with all possible character sets and feed them into aircrack. I will post the output when the key was cracked, including the time it required to crack the key.
