What is DDoS?

FIRST THINGS FIRST:
DDoS is a type of DOS attack where multiple compromised systems, which are often infected with a Trojan, are used to target a single system causing a Denial of Service (DoS) attack. Victims of a DDoS attack consist of both the end targeted system and all systems maliciously used and controlled by the hacker in the distributed attack.

Hacking is illegal in all parts of the world. Do it at your own risk. If caught you will be sentenced and bailed depending on your “Government Jurisdiction Law”.
Some are life in-presentment or 30-40 years in prison.

HOW DOES IT WORK?
According to this report on eSecurityPlanet, in a DDoS attack, the incoming traffic flooding the victim originates from many different sources – potentially hundreds of thousands or more. This effectively makes it impossible to stop the attack simply by blocking a single IP address; plus, it is very difficult to distinguish legitimate user traffic from attack traffic when spread across so many points of origin.
Types of DDoS Attacks
There are many types of DDoS attacks. Common attacks include the following:

Traffic attacks: Traffic flooding attacks send a huge volume of TCP, UDP and ICPM packets to the target. Legitimate requests get lost and these attacks may be accompanied by malware exploitation.

Bandwidth attacks: This DDos attack overloads the target with massive amounts of junk data. This results in a loss of network bandwidth and equipment resources and can lead to a complete denial of service.

Application attacks: Application-layer data messages can deplete resources in the application layer, leaving the target's system services unavailable.
