What type of attack sends Internet Control Message Protocol (ICMP) echo requests to the target machine with a larger payload than the target can handle?

A Man-in-the-Middle attack involves intercepting and potentially altering communications between two parties, not sending malformed ICMP packets to crash a system.

A Denial of Service attack using oversized ICMP echo requests, known as the 'Ping of Death,' sends packets exceeding the maximum IP packet size of 65,535 bytes, causing the target system to crash, freeze, or reboot. Because the attack disrupts the availability of the target system rather than stealing data or intercepting communications, it is classified as a DoS attack. ICMP flood variants also fall under DoS by overwhelming the target with ping requests.

DNS poisoning involves corrupting a DNS resolver's cache to redirect users to malicious sites, which has no relation to sending oversized ICMP packets.

A buffer overflow exploits insufficient input validation in software to overwrite adjacent memory, whereas the Ping of Death targets network stack handling of oversized ICMP packets at the OS/network level rather than a specific application buffer.
