Hi all,
a very quick one:

Being wireless networks broadcast what is the reason why you would use arp spoofing on a wireless network.
I mean i get it if you are on a wired one as with switches you wont intercept someone else's packets so using arp spoofing you place yourself between gateway and client.
But on a wireless network which broadcasts packets because of the nature of the media ( air ), why would you you do this?


Thanks in advance

Simple answer: ethernet broadcasts

edit: just read this

Read that document already but I couldn't get it too much.
Can you be a bit more specific ?

Did you read the ARP Poisoning section in the document linked by biggie_?

Maybe I am have not been clear enough, I am sure my bad English is responsible :-)
my original question was with regards of wireless clients only.
I mean I have a wireless client A connected to AP and I am not interested at ANY wired box.
if I want to sniff packets coming TO and FROM client A,once I am associated with the AP and know the encryption key ( if any ),do I just need to wireshark on my interface to sniff the traffic ?
If I do arp poisoning against the client A would this change the packets quantity,quality and typology at all or would it be exactly the same as wiresharking ?


Thanks.

If all the bad guy cares about is sniffing Ethernet frames, then yeah, it would probably be pointless to mess with ARP. However, ARP poisoning would allow him/her to not only sniff the frames, but also redirect them to hostile nodes, modify them, or even black hole them (DoS). If, for example, his/her objective is to carry out a MITM attack against your Gmail HTTPS session, then being able to sniff Ethernet frames won't on its own do him/her any good, while ARP poisoning could prove to be a vital component in the attack.

Sure,with smthg like sslstrip.
Of course arp poising gives you much more,my question was only an "academic" question.

Thanks
