3. Terminologies in WLAN
 IEEE 802.11:- It is a set of media access control (MAC) and physical
layer (PHY) specifications for implementing wireless local area
network (WLAN).
 3 Way Handshake:- It’s a cryptographic message exchange between
the AP and The client which authenticates the client to connect to the AP.
 Access Point (AP):- An access point is a device, such as a wireless router,
that allows wireless devices to connect to a network
 SSID (Service Set Identity):- It is also known as the "wireless network
name", the SSID is a 32 character, case sensitive name given to a Basic
Service Set established by an access point.

4. Encryption in Wi-Fi
1. Wired Equivalent Privacy (WEP)
 IT is an easily broken security algorithm for IEEE 802.11.
 WEP is the older form of encryption developed around
1997.
 WEP, recognizable by the key of 10 or 26 hexadecimal digits.
 Once this measure has been taken, other typical LAN
security mechanisms such as password protection, end-to-
end encryption, virtual private networks (VPNs),
and authentication can be put in place to ensure privacy.

5. Encryption in Wi-Fi
2. Wi-Fi protected access(WPA)
 It was formally adopted in 2003, a year before WEP was
officially retired.
 A 128-bit WEP key is usually entered as a string of 26
hexadecimal characters.
 Attacker had captured or altered packets passed between
the access point and client and the Temporal Key Integrity
Protocol (TKIP).
 TKIP employs a per-packet key system that was radically
more secure than fixed key used in the WEP system.

6. Encryption in Wi-Fi
3. Wi-Fi Protected Access II (WPA2)
 One of the most significant changes between WPA and
WPA2 was the mandatory use of AES[Advance Encryption
Standard] algorithms.
 WPA2 uses 256 bit AES algorithms for encryption which
makes it much more secure than the ones before it.
 Although breaking into a WPA/WPA2 secured network
using this vulnerability requires anywhere from 5-14 hours
of sustained effort with a modern computer and not be
sure to hack the Successfully.

8. Tools For WI-FI Hacking
 Air crack:- Air crack is the most popular and widely-known
wireless password cracking tools.
 Air Snort:- Air Snort is another popular wireless LAN password
cracking tool.
 Kismet:- Kismet is network sniffer and intrusion detection system.
 Air jack:- Air jack is a Wi-Fi 802.11 packet injection tool.
 Net Stumble:- Net Stumble is another wireless password cracking
tool available only for Windows platform.
 Cloud Cracker :- Cloud Cracker is the online password
cracking tool for cracking WPA protected wi-fi networks.
 Wep Crack:- Cracking WEP

9. History of Kali Linux
 Kali Linux is a Debi an-based Linux distribution aimed at
advanced Penetration Testing and Security Auditing. Kali
contains several hundred tools aimed at various Information
Security tasks, such as Penetration Testing, Forensics and
Reverse Engineering.
 Kali Linux is Developed, Funded and Maintained by Offensive
Security, a leading information security training company.
 Kali Linux was released on the 13th March, 2013 as a
complete rebuild of Backtrack Linux.
 Kali Linux is Named after a Hindu goddess.

10. Developers of Kali Linux

11. Features of KALI LINUX
 Open Source.
 Developed in a secure environment.
 Available in 32-bit and 64-bit images.
 It’s first version of Kali 1.0 was Released on 13th March, 2013.
 It’s newest version Kali 2.0 was released on 11th August, 2015.
 Multi Language Support.
 Rewritten to use Debian standards.
 300+ pentesting applications.
 Users can customize Kali Linux to suit their needs.

12. Steps for Wi-Fi Hacking
Step 1:-
 Start Kali Linux and login, preferably as root.
Step 2:-
 Plug-in your injection-capable wireless adapter, (Unless your native computer
wireless card supports it).

13. Steps for Wi-Fi Hacking
Step 3:-
 Now you will display the kali Linux Home Screen.

14. Steps for Wi-Fi Hacking
Step 4:-
 Open a terminal window by pressing the terminal icon at the top left.
 Otherwise You Press the shortcut key Ctrl + t.
 Terminal are open.

15. Steps for Wi-Fi Hacking
Step 5:-
 Open Terminal and Find out the name of your wireless adapter.,
type ifconfig on a terminal. See the result. (here my wireless adapter is
‘wlan0’)
 et0:- no wireless extensions.
 l0:- no wireless extensions.
 Wlan0:- it will Display the External Wi-Fi Adaptor Information.

16. Steps for Wi-Fi Hacking
Step 6:-
 Next type in the command “airmon-ng”. see if your adapter is seen
by Kali Linux. It should show the interface, chipset, and driver.
n:- It will check the number of wlan0 adaptor
g:- It will check the wlan0 adaptor signal.

17. Steps for Wi-Fi Hacking
Step 7:-
 Type airmon-ng start followed by the interface name of your wireless card.
mine is wlan0.
 my command would be: airmon-ng start wlan0

18. Steps for Wi-Fi Hacking
Step 8:-
 Start capturing packets. we’ll use airmon-ng to capture the packets in the
air.
 You’ll see the name of the Wi-Fi you want to hack.
 type command airodump – ng wlan0mon

19. Steps for Wi-Fi Hacking
Step 9:-
 Now stop the capture packets Ctrl + C.
 Type command:-airodump-ng –c [channel no] --bssid [id] –w
/root/Desktop/ wlan0mon.
 This save the all .cap file into the Desktop.

20. Steps for Wi-Fi Hacking
Step 10:-
 This means that the handshake has been captured, the password is in the
hacker’s hands, in some form or another. You can close the aireplay-ng –
deauth 10 –a [bssid] –c [station] wlan0mon.

21. Steps for Wi-Fi Hacking
Step 11:-
 Actually, it’s the .cap one, that is important. Open a new Terminal, and type
in this command:
aircrack-ng -b [router bssid] -w [path to wordlist] /root/Desktop/ -
02.cap
 -b stands for bssid, replace [router bssid] with the BSSID of the target
router, mine is 00:14:BF:E0:E8:D5.
 -w stands for wordlist, replace [path to wordlist] with the path to a wordlist
that you have downloaded. I have a wordlist called “wpa.txt” in the root
folder.
 aircrack-ng –b 00:14:BF:E0:E8:D5 –w /root/wpa.txt /root/Desktop/*.cap

22. Steps for Wi-Fi Hacking
Step 12:-
 Aircrack-ng will now launch into the process of cracking the password.
However, it will only crack it if the password happens to be in the wordlist
that you’ve selected.
 Cracking the password might take a long time depending on the size of the
wordlist.
 Sometimes, it’s not. If this is the case, you can try other wordlists

23. Steps for Wi-Fi Hacking
Step 13:-

24. Steps for Wi-Fi Hacking
Step 14:-
 The passphrase to our test-network was “123mun3124bili79” and you can
see here that it was in the wordlist, and air crack found it.
