Which DoS attack uses fragmented packets in an attempt to crash a target machine?

A Teardrop attack is a type of Denial of Service (DoS) attack that exploits flaws in how target systems reassemble fragmented IP packets. Attackers send malformed, overlapping, or oversized fragments that confuse the target's TCP/IP stack, causing it to crash, freeze, or become unresponsive while attempting to reconstruct the invalid packets.

A Man-in-the-Middle (MITM) attack involves an attacker intercepting and potentially altering communication between two parties, not primarily crashing a machine with fragmented packets.

A Smurf attack is a type of DoS attack that involves sending ICMP echo requests to an IP broadcast address using a spoofed source IP, causing an overwhelming flood of replies to the victim.

A LAND attack is a DoS attack where a malicious attacker sends a spoofed packet with the same source and destination IP address and port, causing the target system to loop endlessly.
