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.

Functions and features of the WinArpSpoofer program are as follows:


It can pull and collect all the packets on the LAN.
It can scan and show the active hosts on the LAN within a very short time (~1-2 seconds)
While spoofing ARP tables, it can act as another gateway (or ip-forwarder) without other users recognition on the LAN.
It can collect and forward packets by selecting inbound, outbound, and both to be sent to the Internet.
An ARP table is recovered automatically in a little time (about 30 seconds). But, this program can keep spoofing continuously with periodic time.
Although one or more network interface cards are installed on a computer, this program can scan and spoof by selecting one of NICs.
