Hi everyone, i'm back with one of possibly stupid questions of mine. I have a wireless net at home, and i want to understand if, with a standard card, it is possibile to get inside my WLAN. I've been walking around my house with the ibook (with kismet) and i've noticed that i can actually get the signal of my access point. My next try is: i want to check if, by injecting packets to my ap, i can actually crack my wireless (and if so put up some measures to protect my wlan). The only problem is i cannot inject packets with the actual driver (at least, i was not able to)
I don't understand how injecting packets will help crack the wireless. If your AP uses encryption, as your inquiry suggests, anything sent that is not using that encryption scheme will be rejected. The most you will get is a NAK sent in the clear.
If you are using WEP, it can be cracked - there is no question. All it takes is to capture enough packets from a valid connection by just listening. It makes little difference if it is 64-, or 128-bit encryption.
If you are using WPA-PSK, it will be exceedingly difficult to crack if your shared secret is long enough, and truly secret. A length of 20 or more characters is supposed to be enough, particularly if you have upper and lower case alphabetic, numbers, and special characters. If you add TKIP with a reasonably short time (1 hour), it should be extremely difficult to crack your network. On the other hand, anyone that wants the highest security for their information will not use wireless anyway.
