Breaking WPA2- PSK with Kali Linux – Doctor Chaos. WPA2- PSK may not be as safe as you think. There are a few attacks against WAP2- PSK.

One of the most common attacks is against WPA2 is exploiting a weak passphrase. Below you will find a few easy steps on how to break WPA2 with a weak passphrase. Breaking the Wireless Lab Home Network: I set up a test network for this blog article. The client box is logging into my Wireless Lab test network. This is the network we will break. Step 1: The first step is to verify the router configuration. Normally in a real penetration test we would not have this option, but since this is a home lab I have a little more flexibility.

In this case the lab access point is securing the wireless network Wireless Lab with WPA2- PSK. It using the passphrase Cisco. You can use any wireless router to setup your wireless lab. Step 2: We will be using Kali Linux to complete this task. Kali will need a wireless card configured before it can be used by the operating system. I am using the Alfa AWUS0.

NH adapter. Almost any Alfa wireless adapter will work. I am a big fan of the AWUS0. NH adapter because it a duel band adapter. However, this card is very difficult to obtain since it is no longer sold. The iwconfig command will show any wireless cards in the system. I am using a Real.

Tek wireless card. Linux ships with the Real. Tek drivers, making it a Linux plug and play wireless card. The operating system recognizes a  wireless interface named wlan.

There are currently three ways to get Backtrack 5 R3 Direct download, Torrent, or it can be Bought. Download the free trial version below to get started.

He is responsible for providing IT security solutions to major.

Step 3: My next step will be to enable the wireless interface. This is accomplished issuing the ifconfig wlan.

Step 4: I need to understand what wireless networks my wireless card sees. I issue the iwlist wlan. This command forces the wireless card to scan and report on all wireless networks in the vicinity. You can see from this example it found my target network: Wireless Lab. It also found the MAC address of my access point: 0.

E: 1. 8: 1. A: 3. D6: 2. 2. This is important to note because I want to limit my attack to this specific access point (to ensure we are not attacking or breaking anyone else’s password).

Secondly, we see the AP is transmitting on channel 3. This is important because it allows us to be specific on what wireless channel we will want our wireless card to monitor and capture traffic from.

Step 5: The next step is to change the wireless card to monitoring mode. This will allow the wireless card to examine all the packets in the air.

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

From that point create the monitor interface by issuing the command: airmon- ng start wlan. Next, run the ifconfig command to verify the monitor interface is created. We can see mon. 0 is created.

Belnet is the Belgian national research network that provides high-bandwidth internet connection and services to Belgian universities, colleges, schools, research.

Now verify the interface mon. Step 6: Use airodump- ng to capture the WPA2 handshake. The attacker will have to catch someone in the act of authenticating to get a valid capture. Airodump- ng will display a valid handshake when it captures it.

It will display the handshake confirmation in the upper right hand corner of the screen. Note: We will manually connect to the wireless network to force a handshake. In a future post I will show you how to force a reauthorization to make a device automatically disconnect and reconnect without any manual intervention. We used the following command: airodump- ng mon. AP) – –channel 6 (to limit channel hopping) – –write Breaking.

WPA2 (the name of the file we will save to)airodump- ng mon. E: 1. 8: 1. A: 3. D6: 2. 2 – –channel 3. Breaking. WPA2(make sure there is no space between “- - “)To capture the handshake you are dependent on monitoring a legitimate client authenticate to the network. However, it does not mean you have to wait for a client to legitimately authenticate.

You can force a client to re- authenticate (which will happen automatically with most clients when you force a deauthorization). When you see the WPA Handshake Command you know you have captured an valid handshakeexample: Step 7: We will use aircrack- ng with the dictionary file to crack the password. Your chances of breaking the password are dependent on the password file. The command on  is: aircrack- ng “name of cap file you created” - w “name of your dictionary file”The Breaking. WPA2- 0. 1. cap file was created when we ran the airodump- ng command.

The valid WPA2 handshake airodump captured is stored in the Breaking. WPA2- 0. 1. cap file.

Backtrack 5 ships with a basic dictionary. The dictionary file darkc. Back. Track. 5. We added our password Cisco. Many attackers use large dictionaries that increase their chances of cracking a passwords. Many dictionaries contain passwords from real users and websites that have been cracked and posted on the Internet. Some sophisticated dictionaries combine multiple languages, permutations of each word, and key words and phrases from social media sites such as Twitter and Facebook. Kali does not come with the darkc.

NOTE: Kali does have built- in worldlists in: /usr/share/worldlist In this blog we created a file named “sample. Cisco. 12. 3 in it. Success: If the password is found in the dictionary file then Aircrack- ng will crack it.
