ARP Cache Modification Attack

B.

The type of attack described in the question is Spoofing.

Address Resolution Protocol (ARP) is used to map the IP address of a computer to its corresponding MAC address. When two computers communicate with each other, they use ARP to obtain the MAC address of the other computer so that they can send packets to it. An attacker can modify the ARP cache of an internal computer to redirect its traffic to the attacker's computer. This type of attack is called ARP spoofing.

In an ARP spoofing attack, the attacker sends fake ARP messages to the targeted computer, which modifies its ARP cache with the attacker's MAC address instead of the legitimate MAC address of the intended recipient. This allows the attacker to intercept, modify, or steal network traffic that was intended for the victim computer.

Replay attacks involve capturing and replaying network traffic to impersonate a legitimate user. DNS poisoning is a technique used to corrupt the DNS cache of a victim computer or server, which can redirect the victim's web traffic to a malicious website. A client-side attack refers to an attack that targets vulnerabilities in client-side software or applications, such as web browsers or email clients.

Therefore, the correct answer is B. Spoofing.
