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.

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.

ARP spoofing, if successful, enables an attacker to intercept LAN data packets, shape traffic, or stop it altogether. This type of attack is often used as an attacker's opening gambit for other attacks, such as denial of service (DoS), man in the middle (MiTM), or session hijacking. This attack can only be staged on local networks that use Address Resolution Protocol (ARP).

I understand how ARP spoofing works on a switched network: attacker tells the router he's the victim, then tells the victim he's the router. My question is: on large networks, like corporate and university networks, is it still as simple? I would…
