ARP Cache Poisoning 

ARP cache poisoning, also known as ARP spoofing, is the process of falsifying the source Media Access Control (MAC) addresses of packets being sent on an Ethernet network. It is a MAC layer attack that can only be carried out when an attacker is connected to the same local network as the target machines, limiting its effectiveness only to networks connected with switches, hubs, and bridges; not routers.
