What is this?
A bash script to automate cracking WiFi networks! Supports WEP (Client & Client-less), WPA/WPA2, MAC filtering and hidden SSID with the option of connecting afterwards.


How does it work?
> Scans for wireless networks and saves gathered data
> Configures the attacker's wireless card
> Tries to detect currently connected clients
> Starts to capture data
> Depending on encryption on the wireless network - starts different attacks
> Once enough 'essential' data has been collected starts to crack the WiFi key
> Optional: Connect to network with the clients MAC (For MAC Filtering) and WiFi Key


What do I need?
> The bash file, wiffy.sh (37.24 KB, SHA1:49f7a930120544a6cec11171abe500f7042ba49d)
> A wireless card --- that supports monitor mode
> Dictionaries/Word-lists ---If you're wanting to crack WPA/WPA2
> aircrack-ng suite, macchanger --- All on BackTrack!> Optional: Subversion

How do I use it?
1.) Either edit wiffy.sh or specify, via command line, your interface. (You can view your interfaces via ifconfig and use kate to edit.)
2.) If an ESSID or BSSID wasn't set via command line, select which is YOUR network
3.) Wait...
4.) ...Game over. (=


bash wiffy.sh

clear
kate wiffy.sh
iwconfig
bash wiffy.sh -?
clear
bash wiffy.sh -v -e g0tmi1k -x
bash wiffy.sh -x -e g0tmi1k -V

ipconfig /all

Troubleshooting

    WEP
        Didn't detect my client
            Add it in manually
            Re-run the script
        IV's do not increase
            DeAuth didn't work --- Client using Windows 7?
            Use a different router/client
    WPA
        You can ONLY crack WPA/WPA2 when:
            The ESSID is known
            The WiFi key is in the word-list
            There is a connected client 
    Doesn't detect any/my wireless network
        Don't run from a virtual machine
        Driver issue - Use a different WiFi device
        Re-run the script
        You're too close/far away
        Unplug WiFi device, wait, replug
    "Extras"  doesn't work
        Network doesn't have a DHCP server
    Slow
        Re-run the script
        Try a different attack... manually!
    ... still not working correctly?
        Re run with Diagnostics mode enabled (-d)
        Make a note of the setup (Hardware, versions etc)
        Get in touch!

Notes:

    Tested in BackTrack 4 (R1). 
    It's worth doing this "manually" (without the script) before using this, so you have an idea of what's happening, and why. The script is only meant to save time.
    I'm running BackTrack 4 R1 in VM, The target is running Windows 7 Ultimate (fully up-to-date 2010-09-11), with firewall enabled, no AV and with UAC enabled (Windows 7 Default)
