Figure 12-10 ARP Attack – Cheating Gateway
As the above figure shown, the attacker sends the fake ARP packets of Host A to the Gateway,
and then the Gateway will automatically update its ARP table after receiving the ARP packets.
When the Gateway tries to communicate with Host A in LAN, it will encapsulate this false
destination MAC address for packets, which results in a breakdown of the normal communication.
Cheating Terminal Hosts
The attacker sends the false IP address-to-MAC address mapping entries of terminal Host/Server
to another terminal Host, which causes that the two terminal Hosts in the same network segment
can not communicate with each other normally. The ARP Attack implemented by cheating terminal
Hosts is illustrated in the following figure.
