This attack is classified as the 'man in the middle' (MITM) attack.ĪRP spoofing is a type of attack in which a malicious actor sends falsified ARP (Address Resolution Protocol) messages over a local area network. One of the attacks of this kind is Address Resolution Protocol (ARP) Spoofing (sometimes it is called ARP poisoning). These kinds of attacks are generally against layer-2, not against layer-3 or IP. The majority of the internet still uses IPv4 however, so ARP continues to be widely used. It uses a protocol called Neighbor Discovery Protocol (NDP) instead, which employs cryptographic keys to confirm the identity of hosts. ARP poisoning: After a successful ARP spoofing, a hacker changes the company's ARP table, so it contains falsified MAC maps. You can use Windows' Command Prompt, an open-source packet analyzer such as Wireshark, or proprietary options such as XArp.ĪRP spoofing: A hacker sends fake ARP packets that link an attacker's MAC address with an IP of a computer already on the LAN. ARP poisoning can be detected in several different ways.
