Which attack takes place when an attacker responds to an ARP broadcast for the victim's MAC address?

The attack that occurs when an attacker responds to an ARP broadcast for the victim's MAC address is known as ARP Poisoning. This technique involves sending forged ARP (Address Resolution Protocol) responses to a network.

In a typical ARP operation, a device broadcasts an ARP request to find the MAC address associated with an IP address. If an attacker intercepts this request and replies with a maliciously crafted ARP response, they can inform the requesting device that their MAC address is linked to the IP address of another device on the network, often a gateway. This can mislead the legitimate device into sending its traffic to the attacker instead.

As a consequence, ARP Poisoning can enable a range of attacks, including man-in-the-middle attacks, where the attacker can capture, modify, or inject data into the communication between two devices. This makes the understanding of ARP Poisoning critical in network security to implement the necessary mitigations against such vulnerabilities.

ARP Spoofing is often used interchangeably with ARP Poisoning, but the more technically accurate term is ARP Poisoning, as it specifically refers to the act of poisoning the ARP cache of a device. Options like DNS Spoofing and Pharming relate to
