ARP Poisoning (Man-in-the-Middle)

Similar to DHCP poisoning, ARP poisoning involves an attacker manipulating targets' ARP tables so traffic is sent to the attacker.

To do this, the attacker can send gratuitous ARP messages using another device's IP address.

Other devices in the network will receive the GARP and update their ARP tables, causing them to send traffic to the attacker instead of the legitimate destination.
