What Is ARP Spoofing?
ARP spoofing also known as ARP poisoning or ARP attack is a technique in which a host in a LAN can "poison" the ARP table of another host causing it to send packets to the wrong destination. The attacker can modify the traffic in the network such a way that it will redirect all traffic to go through it. ARP Spoofing will allow an attacker to sniff data frames
How ARP Spoofing works?
The image helps to understand how ARP spoofing/ARP poisoning works. Basically, the Cracker is telling Alan's box that he has the IP that corresponds to Brian's box and vice verse.By doing this the Cracker receives all network traffic going between Alan and Brian. Once you have ARP spoofed your way between two machines you can Sniff theconnection with sniffers like ( Wire shark ,Ettercap etc..) By ARP spoofing between a machine and the LANs gateway you can see all the traffic it's sending out to the Internet.

Hi
REPLYI tried this but it kills my Internet connection for the PC I'm trying to poison, regardless whether I do this using my wireless network card or my wired network card.... why wont it let the computer I'm poisoning access the internet, as soon as I turn off arp poisoning internet connection comes back
use Ettercap cain and abel is not that stable !!
Hey thanks for your reply - discovered that it was my firewall which was killing the Internet connection when I started ARP poisoning with Cain - Anyway have gone on to use Ettercap which works fine for Outlook passwords but doesn'tlog any http or https usernames or passwords - Have tried with my gmail password and my yahoo password and nothing was logged. Used the Ettercap addons to check everything was working and poisoning as required which was fine yetnothing was detected - any ideas?
REPLYThanks
@Anonymous
gmail and yahoo mail uses https (ssl) this works only in http connections !!
