This document provides an overview of wireless hacking and WiFi security. It discusses basic WiFi terms like SSID, BSSID, and MAC addresses. It explains how wireless networks work by transmitting data packets between devices and access points. Common wireless encryption standards like WEP, WPA, and WPA2 are described as well as how they can be cracked. Tools for wireless hacking in Backtrack like Airodump-ng, Aireplay-ng, and Aircrack-ng are introduced along with how they can be used to crack encryption keys through techniques like dictionary attacks and capturing handshakes. The document concludes by stating it is time to start hacking wireless networks.

2. WIFI – WIRELESS FIDELITY
 Wi-Fi,
is a popular technology that allows an
electronic device to exchange data or
connect to the internet wirelessly using
radio waves.
 Wireless
access allows users to connect to
the internet from any location within range
of a wireless access point.

3. SOME BASIC TERMS

MAC address or physical address is a unique
identifier assigned to network interfaces for
communications

Access point >> Wireless router

SSID (service set identifier) >> Network Name

BSSID (basic service set identification ) >>
MAC address of the access point

4. BASIC WORKING
When a user uses wireless internet they generate
what are called data “packets”.
 Packets are transmitted between the wireless card
and the wireless access point via radio waves
whenever the computer is connected with the
access point.


5. BASIC WORKING CONTD.

Depending on how long the computer is
connected, it can generate a certain number of
packets per day.

The more users that are connected to one access
point, the more packets are generated.

6. WIRELESS ENCRYPTION
 The
main source of vulnerability associated
with wireless networks are the methods of
encryption. There are a few different type of
wireless encryption including:



WEP
WPA
WPA2

7. WEP
Stands for Wired Equivalent Privacy.
 WEP is recognizable by the key of 10 or
26 hexadecimal digits.


8. WPA OR WPA2
Stands for Wi-Fi Protected Access
 Created to provide stronger security
 Still able to be cracked if a short password is used.
 If a long passphrase or password is used, these
protocol are virtually not crackable.


WPA-PSK and TKIP or AES use a Pre-Shared Key (PSK) that
is more than 7 and less than 64 characters in length.

9. USING BACKTRACK >>
 Some



Basic Backtrack Terms >>
Wlan0 – wireless interface
Mon0 – monitor mode
Handshake –
refers to the negotiation process between the computer
and a WiFi server using WPA encryption.
 Needed to crack WPA/WPA2.

Dictionary - consisting the list of common
passowords.
 .cap file – used to store packets.


10. MONITOR MODE

Monitor mode, or RFMON (Radio Frequency
MONitor) mode, allows a computer with a wireless
network interface controller (WNIC) to monitor all
traffic received from the wireless network.

Monitor mode allows packets to be captured
without having to associate with an access point
first.

11. TOOLS USED
Airmon-ng >> Placing different cards in monitor
mode
 Airodump-ng (Packet snniffer ) >> Tool used to listen
to wireless routers in the area.
 Aireplay-ng ( Packet injector ) >> Aireplay-ng is
used to inject frames.



The primary function is to generate traffic for the later use
in aircrack-ng for cracking the WEP and WPA-PSK keys.
Aircrack-ng >> Cracks WEP and WPA (Dictionary
attack) keys.
