Which of the following network attacks relies on sending an abnormally large packet size that exceeds TCP/ IP specifications?

The ping of death exploits the fact that IPv4 packets are limited to 65,535 bytes; by fragmenting an oversized ICMP packet and reassembling it on the target, the overflow can corrupt memory and crash vulnerable systems. This directly violates TCP/IP specifications for maximum transmission unit sizes. It is distinct from volumetric floods because it relies on a single malformed oversized packet rather than traffic volume.

SYN flooding exploits the TCP three-way handshake by sending many SYN packets without completing connections, exhausting the target's connection table rather than sending oversized packets.

TCP hijacking involves intercepting and taking over an established TCP session, not sending malformed oversized packets.

A Smurf attack uses ICMP broadcast amplification by spoofing the victim's IP in echo requests sent to a broadcast address, not abnormally large packet sizes.
