Welcome to the world of DDoS attacks, I am sure you have seen these,
herd of these, experienced these ect. Now I am going to take you into
how they work.
First thing we are going to talk about is the "4 layer DDoS attack" which is the most common type of DDoS attack which is when many attackers hit a target at the same time. This is usually done with easy access tools such as the "Low Orbit Ion Cannon" or "Command Prompt"
this is just basically sending thousands of packets per second to a target, and flooding the server until it goes down.
This is a very weak kind of attack if using it by yourself, but with 100's or thousands of people all doing it at the same time it is very effective.
Next type of attack I will be discussing is the "Layer 7 DDoS Attack" this is more advanced, how this works is instead of just constantly sending packets to the server you send it an HTTP get request but if you just send part of it and not the other half, so the server is expecting the other half wich ties up most of the server this is also called the "Slowloris" attack, with this you can freeze a server up very quickly, the most famous person who uses these attacks is th3j35t3r who is said to be able to hold off sites with a 3g cellphone.
