Savio this program is great.
I have some additional questions.. can you confirm?

Is MAC address changer automated when I initiate the attack? Or does it have to be changed prior to attacking?
Reagrding WPA/WPA2, are the attacks using reaver by default?
I see you have some options for WEP, Fragmentation,Chop-Chop, Caffe-Latte, Hirte, ARP Request Replay.. does Fern cycle through these till it cracks? Or do you have to manually select/try each method?
