WinArpSpoofer is a program to manipulate the ARP table of another computer on a LAN. Especially, by changing the ARP table of a router, this program can in effect pull all packets on the local area network. After pulling and collecting all packets, this has a function that can forward them to the router(gateway). If you run this program and any sniffer program, you can even get and see all user ids/passwords on the switch network.
