Questions tagged [arp-spoofing]

ARP spoofing is an attack technique which sends spoofed Address Resolution Protocol (ARP) messages to Local Area Network (LAN). The idea is to identify attacker's MAC address as the address of another network host and redirect traffic intended for another IP address to the attacker's IP address instead.
