fuck exploits, just get yourself a compatible wifi card for backtrack that comes with an antenna attachment. get a yagi directional wifi antenna for 80$. the nice 16dbi ones. then get a 1000mw/1watt wifi signal booster for about 63$ "just get the chinese ones they work the same" hook it all up and you get wifi range up to 5000ft or so.
learn how to packet sniff/arp poison and steal all their info not just myspace lol.
while your are it arp poison with an image filter running so every website they load the pictures get replaced with w/e u want such as goatse.
then steal their info and try not to get caught.
o btw dont point that antenna at anything you care for at a close range with that amplifier hooked up. such as tv's,cell phones, yourself. that would just be baddddddd
