Ping of Death is a type of attack that aims to send large packets to the targeted machine, causing it to crash or freeze.

Sent packets are often much larger than the device's allowable capacity, which can make your device unstable. The attack first appeared in the 1990s and appeared to affect the operating system's TCP/IP framework.

PoD Attacks are a form of DOS attack and send ICMP (Internet Control Message Protocol) packets to the targeted system via pings.

The main purpose of the Ping of Death attack is to overload the system by making it unstable. By sending large packets of 65,535 bytes, it causes crashes in various operating systems such as Unix, Linux, Mac, Windows.

The "Total Length" field in the IPv4 header is a 16-bit field. The maximum possible value of a 16-bit binary number is 65,535. Sending an ICMP packet larger than 65,535 bytes in an IPv4 datagram violates the IPv4 Protocol. When the target computer tries to reassemble parts of large malformed IPv4 datagrams containing the ICMP message, a buffer overflow of the ping command may occur, possibly freezing or crashing the target machine.
