What are some types of ICMP attacks?
Ping of death: an attack is based upon the use of oversized ICMP packets. If a system does not know how to handle ICMP packets over the common size of 65,536 bytes then it can become unstable and freeze or crash. This is a DDoS attack that is carried out to render the target system unable to process legitimate traffic.
Smurf attack: an attacker sends an ICMP ECHO REQUEST packet with a spoofed source address to a victim’s network broadcast address. This means that each system on the victim’s subnet receives an ICMP ECHO REQUEST packet. Each system replies to that request with an ICMP ECHO REPLY. All of these responses can overwhelm the victim’s system and cause it to crash.
Fraggle attack: similar to the Smurf Attack, however, Fraggle uses UDP protocol.
