ICMP floods. Also known as “ping flood attacks,” these attacks bombard targets with ICMP echo requests from many spoofed IP addresses. The targeted server will have to respond to all of these requests and gets overloaded and not able to approach valid ICMP echo requests.
You see a surge in web website traffic, seemingly from nowhere, that’s coming from the similar IP handle or vary.
