Then users would not know that the attacker is not the real host on the network. ARP spoofing attacks can be run from a compromised host on the LAN, or from an attacker's machine that is connected directly to the target LAN.Īn attacker using ARP spoofing will disguise as a host to the transmission of data on the network between the users. The basic principle behind ARP spoofing is to exploit the lack of authentication in the ARP protocol by sending spoofed ARP messages onto the LAN. This behavior is the vulnerability that allows ARP spoofing to occur.
There is no method in the ARP protocol by which a host can authenticate the peer from which the packet originated. Even ARP entries that have not yet expired will be overwritten when a new ARP reply packet is received. Network hosts will automatically cache any ARP replies they receive, regardless of whether network hosts requested them.

The destination machine with the IP in the ARP request then responds with an ARP reply that contains the MAC address for that IP. When another host's IP address is known, and its MAC address is needed, a broadcast packet is sent out on the local network. When an Internet Protocol (IP) datagram is sent from one host to another in a local area network, the destination IP address must be resolved to a MAC address for transmission via the data link layer. The Address Resolution Protocol (ARP) is a widely used communications protocol for resolving Internet layer addresses into link layer addresses.
