#How to get a wifi password off your mac password
There are many lists of common passwords online, so if the Wifi password is something easy to guess like ‘Password123,’ you’ll crack it with ease. Sudo aircrack-ng -w pass.txt -b capture-01.cap We are now going to try to guess the password using a long wordlist of possible passwords and iterating through the options in the list by running aircrack-ng with: The difficulty of cracking the password depends on how complicated the password is. The MIC and the Nonces are captured in the file, so now you can attempt to crack the password with your own password list.
The airodump instance should have captured wireless data and saved in. Now that you’ve captured the 4-way handshake, you can try to crack the password. If you look back at your airodump page, you’ll see that now you have captured a WPA handshake! 4. Keep the airodump running, then issue the following command:Īireplay-ng -0 1 -a -c wlan0mon To speed things up a bit, we can issue what’s called a deauthentication packet to a device, which will kick the device off of the Wifi, forcing it to reconnect, and allowing us to capture the handshake. In order to capture the 4-way handshake, we have to wait for a device to connect to the AP while we are listening.
In my case, the different stations are the different devices connected to my Wifi, including my phone, laptop, and Amazon Echo. The command will show you all of the different clients currently connected to the specified AP.
-w: Write to a file, in this case prefix all files with “capture”. -c: Specifies channel to listen on, in this case Channel 6. Long story short, cracking WPA2 Wifi passwords consists of capturing the 4-way handshake, parsing out the Nonce values, and generating your own PTK with a password list and checking the generated MIC against the original captured value to see if the password is correct.Ĭapture data on the channel of your Wifi target, with:Īirodump-ng -c 6 –bssid -w capture wlan0mon The PTK is generated with random values known as Nonces, and the last 128 bits of the key is what’s known as a MIC. The handshake is used to establish a secure connection between the two parties before transferring information.īefore the handshake is sent, both the AP and the client have a PMK, or Pairwise Master Key, which is the Wifi password, and used to create a PTK, or Pairwise Transit Key. In order to crack the Wifi password, we are going to capture a 4-way handshake between a client (like your phone or laptop) and an access point (the router). If you don’t get any results, even though you’re sure there are Wifi networks around you, try restarting the network interface by running ifconfig up then ifconfig down right after. The “CH” column indicates which channel the AP is broadcasting on. The “PWR” column also signals how close the network is, with a smaller number being closer. Run it for a bit, and you’ll discover all of the Wifi networks around your area (within the range of your wireless adapter), including their network names, their BSSID (MAC address), and encryption method. To start discovering the Wifi networks in your range, run airdump-ng wlan0mon. If you run iwconfig again, you’ll have a new interface called wlan0mon, which confirms that your wireless adapter is in monitor mode and can now collect data. Next, start the airmon-ng tool with airmon-ng start wlan0, which initializes your wireless adapter to monitor on the wlan0 wireless interface. Run airmon-ng check kill, which will end any processes that may interfere with airmon-ng, the wireless monitoring tool. Monitoring Wifi Networksīefore you can start to monitor the Wifi networks in your area, you need to kill any running processes that may interfere with your program. Wlan0 should now be populated with your wireless device. In Virtual Box, once you’re in the VM, select Devices in the upper option bar, select USB, then select the WLAN Wireless Adapter, which should show up in the options.Ĭheck to see if you’ve successfully connected the USB to your VM by running iwconfig. 
Instructions: What you’ll need:įirst, you’re going to need to connect your Wireless Adapter to your Kali VM. The one I’ll be using is the ALFA AWUS036NEH, and it can be found on Amazon. Make sure that the adapter you purchase is compatible with Kali Linux, a good list can be found here. You’ll also need to have a Wireless Adapter to capture wireless packets.
I’ll be walking through the steps with a Kali Linux 2020.2 VM, running on Virtual Box, and using Aircrack-ng, a tool suite already preinstalled on Kali.

This tutorial will show you how to snoop on the Wifi networks around you, capture a WPA2 authentication handshake, and crack the Wifi password. Only try these techniques on networks that you own or have explicit permission to hack, doing otherwise is illegal. Let me start this off by saying do not actually hack your neighbor’s Wifi.
