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 trafic in the network such a way that it will redirect all traffic to go through it. The attacker can then forward the traffic to the right destination or block it causing DoS attack on the victim.
