How to hack a Wifi password using Kali Linux

how to hack a wifi password using kali linux


Frequently asked question online, how to hack a wifi password! Most people will probably answer by referring you to funny phone apps lol. I’m not gonna do that, instead, I’ll share with you a better and more efficient way of pulling off this hack; How to hack a wifi password and get connected using Kali Linux.


Plus this method is a bonus since it exposes you a little to the hack hood.


I didn’t want to give you, my audience what you can easily find elsewhere on the net, so I went to work and manipulated some commands using Kali.


I’m sure you’re quite familiar with and already installed Kali Linux, if not, you’re in luck because I’ve pretty much covered it here.


The purpose of this particular attack is to capture as many traffic as we can get using airodump-ng. Each data packet has an associated 3-byte Initialization Vector called IV’s.

The goal after the hack is initiated is to obtain as many encrypted IV’s as possible, then use aircrack-ng on the captured file to reveal the password.


Don’t know much about hacking? Worry not bro/sis, because we’re gonna do it together.




Get your computer.



STEP 1


The very first thing we’ll need to do is to verify the router configuration. Normally we wouldn’t have this option in a real penetration test, but we got some flexibility since we’re operating in a home lab.


For the purpose of this tutorial, the passphrase Cisco123 is used in the lab access point to secure the wireless network with WPA2-PSK.


Use any wireless router to set up your wireless lab.

Setup an old router, log in and set it up as WEP, so wireless security can use it as a test router.

Connect your phone or any other device to its wireless. This is so to capture the encrypted data between the two.


STEP 2


The iwconfig command will show all wireless cards in any system. We'll use a RealTek wireless card(this is a Linux plug and play wireless card).


The operating system will recognize a wireless interface called Wlan0

STEP 3


The next step we’ll make is to enable the wireless interface. This is done using the ifconfig wlan0 up command.

STEP 4


Now, you need to know the specific wireless network your wireless card sees. So carry out the iwlist wlan0 scanning command.

This command instructs the wireless card to reveal all wireless networks in your area.
You’ll clearly see in the below image that it found my target network; wireless lab.


It found also the MAC address of my access point; 0E:18:1A:36:D6:22. It’s important you note yours’s because you’d want to limit your attack to a specific access point to ensure you’re not breaking into anyone’s password(Illegal bruh).



Also, note the fact that the AP is transmitting on channel 36. This is important because it allows you to know what wireless channel you’ll want your wireless card to capture traffic from.

STEP 5


Change the wireless card to monitoring mode. This allows the wireless card to check all the packets available.


You can do this by creating a monitor interface using airmon-ng. Issue this command to verify that airmon-ng sees your wireless card.


Create the monitor interface by writing the command; airmon-ng start wlan0

Run the ifconfig command to verify that the monitor interface has been created.

Now verify that the mono interface has been created.

STEP 6


Use the airodump-ng to capture the WPA2 handshake. Airodump-ng will show a valid handshake when it captures it. This will be shown in the upper right-hand corner of your computer screen.


You’ll have to manually connect to the wireless to force a handshake. I’ll soon write an article describing how to force a reauthorization, making a device automatically disconnect and reconnect with no need for a manual intervention.


Use the command in this format; airodump-ng mon0 --bssid 20:aa:4b:1f:b0:10 =used to capture packets from your AP

--channel 6 =limits channel hopping

--write BreakingWPA2 =the name of the file you wish to save to


Airodump-ng mon0 --bssid 0E:18:1A:36:D6:22 --channel 36 --write breakingWPA2


NOTE: MAKE SURE YOU LIVE NO SPACE BETWEEN “_ _”




To successfully capture the handshake, you’re gonna monitor a legitimate client to authenticate to the network.


To fix the hassle of having to wait for a client to legitimately authenticate. I’m gonna show you to force a client to re-authenticate.


Look out for the WPA Handshake Command, this tells you that you just captured a valid handshake.




STEP 7


Now, we’re gonna use aircrack-ng together with the dictionary file to crack the password.
Our chances of breaking into the password are largely dependent on the password file.


The command is; aircrack-ng “title of the cap file you created and stored” –W “title of your dictionary file”




The BreakingWPA2-01.cap file was created when we ran the airodump-ng command. The valid WPA2 captured airodump handshake is saved in the BreakingWPA2-01.cap file


Backtrack 5 comes with a basic dictionary, darkc0de.lst. This is a popular worldlist that ships with BackTrack5. We used our password Cisco123 in this file to make the test run smoother. Many hackers use large dictionaries which increases their chances of cracking passwords. Lots of dictionaries contain passwords from real users and websites that was cracked and posted on the web.


You can download the darkc0de.Ist here since Kali Linux does not come with it preinstalled.

If the password is found in the dictionary file, rest assured that aircrack-ng will crack it and you'll be able to connect.

SUCCESS!


Whew, just got that out of the way.

Now, let's hope my hack also works for you. If it doesn't, hit me up. We'll figure it out together.

Now check out how you can hack into a computer
