Intruders use a technique called MAC (media access control) spoofing to hack into a victim’s computer by using the MAC address of another computer to send an ARP (Address Resolution Protocol) response packet to the victim even though the victim did not send an ARP request. The victim host renews the internal ARP table using the malicious ARP response packet. See also Anti-MAC Spoofing.
