1, manual DDoS attack.

Early DDoS attacks were all manually configured, that is, when launching DDoS attacks, scanning vulnerable computers at the remote end, invading them and installing codes were all done manually.

2. Semi-automatic DDoS attack.

In semi-automatic attack, DDoS attack belongs to the attack mode of master client and proxy client. The attacker uses an automatic script to scan, and the main client's machine will record the attack type, the victim's address and the time when the attack was launched in detail.

3. Automated DDoS attacks.

In this attack. Communication between the attacker and the proxy machine is absolutely not allowed. The attack stage of this kind of attack is mostly limited to a single command, and all the characteristics of the attack, such as attack type, duration and victim address, are pre-programmed in the attack code. ?
