Explanation

A LAND attack sends a TCP SYN packet where the source IP and source port are spoofed to exactly match the destination IP and destination port of the target. The victim system sends a SYN-ACK back to itself, enters an infinite loop trying to complete the handshake, and may crash or hang. A Boink/Teardrop attack fragments packets maliciously; a Smurf attack uses ICMP broadcast amplification. The looped self-reply is the defining characteristic of a LAND attack.
