Ping flood is predicated on sending the sufferer an amazing quantity of ping packets, ordinarily utilizing the ping command from Unix-like hosts.[a] It is quite simple to launch, the main necessity becoming entry to higher bandwidth when compared to the victim.
Soon after creating a enormous botnet of a lot of compromised devices, a DDoS attacker remotely directs Every single bot to mail requests into the focus on’s IP handle.
Amplification: This really is an extension of reflection, where the response packets despatched towards the victim because of the third-party techniques are larger sized in dimension compared to attackers’ packets that brought on the responses.
