ARP Attacks
ARP Spoofing and ARP Poisoning are related concepts.
The attacker spoofs an IP on the network, usually the default gateway, with the MAC address of their machine, to intercept all user traffic.
This leads to ARP poisoning where device IP-to-MAC tables now contain false bindings.
Successful ARP attacks lead to traffic hijacking, traffic denial, or man-in-the-middle attacks.
