Re: Spoofed IP address[Scanned]

If I remember correctly, the attacker doesn't use the same IP address... its
sends a forged ARP packet to the server to change the MAC address entry into
the server's ARP table to point to the attackers IP.

I think the solution to this is to setup a broadcast listener... a machine
that listens to Transmissions over the broadcast IP such as ARP requests.
The broadcast listener should listen out for MAC and IP spoofing.

Thanks everyone who read and answer my question.

Given a scenario as below:

When someone wants to launch a man-in-the-middle attack on the
communication between the client and server. In order to make it more
transparent(hard to discover) can the attacker pretended to has the same
IP address as the server(when handling the communication with client
end) while pretending to has the same IP address as the client(when
handling the communication with server end). If it is possible, can you
tell me your solutions.

This is not used to generate real attacks, it is just a concern I come
cross when designing a communication system.

Thanks a lot.
