In this chapter, we will learn how to use Wi-Fi cracking tools that Kali Linux has incorporated. However, it is important that the wireless card that you has a support monitoring mode. About Kali Linux Wireless Attacks.

Fern Wifi Cracker

Fern Wifi cracker is one of the tools that Kali has to crack wireless. This is a Kali Linux Wireless Attacks tools.

Before opening Fern, we should turn the wireless card into monitoring mode. To do this, Type “airmon-ng start wlan-0” in the terminal.

Now, open Fern Wireless Cracker.

Step 1 − Applications → Click “Wireless Attacks” → “Fern Wireless Cracker”.

Step 2 − Select the Wireless card as shown in the following screenshot.

Step 3 − Click “Scan for Access Points”.

Step 4 − After finishing the scan, it will show all the wireless networks found. In this case, only “WPA networks” was found.

Step 5 − Click WPA networks as shown in the above screenshot. It shows all the wireless found. Generally, in WPA networks, it performs Dictionary attacks as such.

Step 6 − Click “Browse” and find the wordlist to use for attack.

Step 7 − Click “Wifi Attack”.

Step 8 − After finishing the dictionary attack, it found the password and it will show as depicted in the following screenshot picture.

Kismet

Kismet is a WIFI network analyzing tool. It is a 802.11 layer-2 wireless network detector, sniffer, and intrusion detection system. It will work with any wireless card that supports raw monitoring (rfmon) mode, and can sniff 802.11a/b/g/n traffic. It identifies the networks by collecting packets and also hidden networks.

To use it, turn the wireless card into monitoring mode and to do this, type “airmon-ng start wlan-0” in the terminal.

Let’s learn how to use this tool.

Step 1 − To launch it, open terminal and type “kismet”.

Step 2 − Click “OK”.

Step 3 − Click “Yes” when it asks to start Kismet Server. Otherwise it will stop functioning.

Step 4 − Startup Options, leave as default. Click “Start”.

Step 5 − Now it will show a table asking you to define the wireless card. In such case, click Yes.

Step 6 − In this case, the wireless source is “wlan0”. It will have to be written in the section “Intf” → click “Add”.

Step 7 − It will start sniffing the wifi networks as shown in the following screenshot.

Step 8 − Click on any network, it produces the wireless details as shown in the following screenshot.

GISKismet

GISKismet is a wireless visualization tool to represent data gathered using Kismet in a practical way. GISKismet stores the information in a database so we can query data and generate graphs using SQL. GISKismet currently uses SQLite for the database and GoogleEarth / KML files for graphing.

Let’s learn how to use this tool.

Step 1 − To open GISKismet, go to: Applications → Click “Wireless Attacks” → giskismet.

As you remember in the previous section, we used Kismet tool to explore data about wireless networks and all this data Kismet packs in netXML files.

Step 2 − To import this file into Giskismet, type “root@kali:~# giskismet -x Kismetfilename.netxml” and it will start importing the files.

Once imported, we can import them to Google Earth the Hotspots that we found before.

Step 3 − Assuming that we have already installed Google Earth, we click File → Open File that Giskismet created → Click “Open”.

The following map will be displayed.

Ghost Phisher

Ghost Phisher is a popular tool that helps to create fake wireless access points and then later to create Man-in-The-Middle-Attack.

Step 1 − To open it, click Applications → Wireless Attacks → “ghost phishing”.

Step 2 − After opening it, we will set up the fake AP using the following details.

• Wireless Interface Input: wlan0
• SSID: wireless AP name
• IP address: IP that the AP will have
• WAP: Password that will have this SSID to connect

Step 3 − Click the Start button.

Wifite

It is another wireless clacking tool, which attacks multiple WEP, WPA, and WPS encrypted networks in a row.

Firstly, the wireless card has to be in the monitoring mode.

Step 1 − To open it, go to Applications → Wireless Attack → Wifite.

Step 2 − Type “wifite –showb”to scan for the networks.

Step 3 − To start attacking the wireless networks, click Ctrl + C.

Step 4 − Type “1” to crack the first wireless.

Step 5 − After attacking is complete, the key will be found.
