ICMP flood, also known as ping flood, is a popular DoS technique in which an intruder overwhelms a victim’s computer with ICMP echo requests, also known as pings, to bring the target down.
The attack is executed when the hacker sends packets as quickly as feasible without waiting for responses. Since the target’s servers will frequently try responding with ICMP echo reply packets, the ping flood attack causes a sizable system delay by using both the outgoing and incoming bandwidth.
There is an exclamation mark that signifies the success of the router and the remote host. On a local network, expect close to a 100% success rate. However, the usefulness of the information may decrease as the data travels around the internet. ICMP essentially drains all available bandwidth until it runs out.
The ICMP protocol is primarily used to determine whether data is arriving at the intended destination in a timely way. The ICMP protocol is commonly used on network devices like routers. In addition, ICMP is essential for error analysis and testing.
