APR (ARP Poison Routing) is a main feature of the program. It enables sniffing on switched networks and the hijacking of IP traffic between hosts. The name "ARP Poison Routing" derives from the two steps needed to perform such unusual network sniffing: an ARP Poison Attack and routing packets to the correct destination.
ARP Stands For Address Resolvation Protocol
ARP Poison Attack
This kind of attack is based on the manipulation of host's ARP caches. On an Ethernet/IP network when two hosts want to communicate to each other they must know each others MAC addresses. The source host looks at its ARP table to see if there is a MAC address corresponding to the destination host IP address. If not, it broadcasts an ARP Request to the entire network asking the MAC of the destination host. Because this packet is sent in broadcast it will reach every host in a subnet however only the host with the IP address specified in the request will reply its MAC to the source host. On the contrary if the ARP-IP entry for the destination host is already present in the ARP cache of the source host, that entry will be used without generating ARP traffic.
