# ARP Spoofing

A technique where an attacker sends falsified ARP (Address Resolution Protocol) messages on a local network, linking the attacker's MAC address to a legitimate IP address. In TLCTC: the ARP spoofing itself is `#1 Abuse of Functions` (abusing a legitimate network protocol without exploiting an implementation flaw). ARP spoofing typically leads to a Man in the Middle position, making the full sequence `#1 → #5`.
