Wireless arp security


Recommended Posts

not sure if this is where i should post this but just wondering am i doing something wrong.

I am on my wireless network and when i run SmartSniff.exe its like ethereal but when i run this i get all packets from all the computers on my wireless is this correct? Just been watching hack5-ep3.5 and they said you have to do the arp attack but this does not seam that i have to do this i get everyones packets.

But on wired network i have to do the arp attack

Thanks does this make sense?

If the card is set to promiscuous mode all packets received (whether or not it's for that computer) will 'make it to the operating system'. Basically, assume that a wireless network is HUB'ed together rather then switched. (HUB'ed = no ARP poisoning required, Switched = ARP poisoning required)
