Whenever we mention DDoS attacks, We now have to mention its amplification result. In order to realize amplification, most attackers leverage botnets consisting of compromised desktops, permitting them to amplify their attack through the size of your botnet. Just one attacker can Handle one,000 bots which can then be accustomed to DDoS the target.
The contaminated machines await a remote command from the command-and-Regulate server that is definitely utilized to initiate and control the attack and is frequently itself a hacked machine.
