In this tutorial, we will introduce you to common techniques used to exploit weaknesses in wireless network security implementations. We will also look at some of the countermeasures you can put in place to protect against such attacks. A wireless network is a network that uses radio waves to link computers and other devices together.

The implementation is done at the Layer 1 physical layer of the OSI model. You will need a wireless network enabled device such as a laptop, tablet, smartphones, etc. You will also need to be within the transmission radius of a wireless network access point. Most devices if the wireless network option is turned on will provide you with a list of available networks. If the network is not password protected, then you just have to click on connect.

If it is password protected, then you will need the password to gain access. Since the network is easily accessible to everyone with a wireless network enabled device, most networks are password protected. It was developed for IEEE Its goal was to provide the privacy equivalent to that provided by wired networks. WEP works by encrypting the data been transmitted over the network to keep it safe from eavesdropping. Open System Authentication OSA — this methods grants access to station authentication requested based on the configured access policy.

The station encrypts the challenge with its key then responds. If the encrypted challenge matches the AP value, then access is granted. It is used to encrypt data on I've created a simple tool that makes hashcat super easy to use called naive-hashcat. You can also try your hand at CPU cracking with Aircrack-ng. Note that both attack methods below assume a relatively weak user generated password. If you are attempting to crack one of these passwords, I recommend using the Probable-Wordlists WPA-length dictionary files.

Before we can crack the password using naive-hashcat, we need to convert our. You can do this easily by either uploading the. Naive-hashcat uses various dictionary, rule, combination, and mask smart brute-force attacks and it can take days or even months to run against mid-strength passwords. The cracked password will be saved to hackme. Where the last two fields separated by : are the network name and password respectively.

If you would like to use hashcat without naive-hashcat see this page for info. Aircrack-ng can be used for very basic dictionary attacks running on your CPU. Before you run the attack you need a wordlist. I recommend using the infamous rockyou dictionary file:. A deauth attack sends forged deauthentication packets from your machine to a client connected to the network you are trying to crack.

These packets include fake 'sender' addresses that make them appear to the client as if they were sent from the access point themselves. Upon receipt of such packets, most clients disconnect from the network and immediately reconnect, providing you with a 4-way handshake if you are listening with airodump-ng.

Now, leave airodump-ng running and open a new terminal. We will use the aireplay-ng command to send fake deauth packets to our victim client, forcing it to reconnect to the network and hopefully grabbing a handshake in the process. Once you've sent the deauth packets, head back over to your airodump-ng process, and with any luck you should now see something like this at the top right: [ WPA handshake: 9C:5C:8E:C9:AB:C0.

Now that you've captured a handshake you should be ready to crack the network password. The response to this tutorial was so great that I've added suggestions and additional material from community members as an appendix. Check it out to learn how to:. Much of the information presented here was gleaned from Lewis Encarnacion's awesome tutorial.
