Address Resolution Protocol

The address resolution protocol (ARP) resolves a IPv4 address to the corresponding MAC address.

Man in the Middle (MitM) Attack

Wireshark MitM


We will demonstrate ARP poisoning attacks against the telnet protocol. Telnet is a method of remotely accessing a server.

Telnet is legacy software, it transmits sensitive content in plaintext. We’re using it for demonstrational purposes. Never use telnet in practice.

ARP Poisoning

The aim is to associate the attacker’s MAC address with the IP address of another host, […] causing any traffic meant for that IP address to be sent to the attacker instead.
