What Is Ddos Attack And How Does It Work?



 What Is Ddos Attack And How Does It Work?

Many of  people in illusions that Website hacking and Attacking is very Difficult and only some hackers and professionals can Do It... Now that's absolutely wrong thinking... Its as Easy as alphabetic. 


First of all We all should know What are the Different Methods Of attacking Websites...
There are Generally Three Methods of Attacking an Website...
1. Ddos Attack
2. Shell Scripts Attack

3. Javascript Attack or Attack through Scripting.

Note: SQL and other techniques comes in the Hacking Websites Part Not in attacking Part. Attacking is simply for fun or intentionally causing damage to the Website.. 
  
Ddos Attack

What is a Distributed Denial of Service (DDoS) attack?

Have you ever tried to make a telephone call but couldn't because all the telephone circuits were busy? This may happen on a major holiday and often happens on Diwali,New year etcc.

The reason you couldn't get through is because the telephone system is designed to handle a limited number of calls at a time. 

So upto now you will Got an Idea What is Ddos(Distibuted Denial of Service) Attack.
Basically Ddos attack is an attack which makes the Network So congested such that no further Requests are delivered.

This is Done by making a number of connections to the Websites through Different Computer or Networks. Also can be done from One Computer by making Connections through Different Ports as there are 64k ports available in WindowsOS.


How Attacker Launch a Ddos Attack?

Over past years Denial of service attack has made huge amount of damage,Many of the have been victimed of this attack

Its Real,On February 6th, 2000, Yahoo portal was shut down for 3 hours. Then retailer Buy.com Inc. (BUYX) was hit the next day, hours after going public. By that evening, eBay(EBAY)Amazon.com (AMZN), and CNN (TWX) had gone dark. And in the morning, the mayhem continued with online brokerE*Trade (EGRP) and others having traffic to their sites virtually choked off.

This attack also recently hit twitter on 6th August 2009,lot of people had trouble on logging on twitter,It was brought down by denial of service attack,They tired up there server so no one can get on log on it.Websites likefacebook, eBay etc have also been victim of this attack.

First, Attackers build a network of computers that will be used to produce the volume of traffic needed to deny services to computer users. We'll call this an "attack network".

 To build this attack network, Attackers look for computers that are poorly secured, such as those that have not been properly patched, or those with out-of-date or non-existent anti-virus software. When the Attackers find such computers, they install new programs on the computers that they can remotely control to carry out the attack.

These days, however, the process of building an attack network has been automated through self-propagating programs. These programs automatically find vulnerable computers, attack them, and then install the necessary programs. The process begins again as those newly compromised computers look for still other vulnerable computers. 

Once an attack network is built, the intruder is ready to attack the chosen victim or victims. Some informationsecurity experts believe that many attack networks currently exist and are dormant, passively waiting for the command to launch an attack against a victim's computers. Others believe that once a victim has been identified, the attack network is built and the attack launched soon afterward.

So guys i think this is enough for today hope you all now familer with Ddos attack in future post will we show how to do Ddos attacks with various hacking tools like Serve Attack Pro and LOIC (Low Orbit Ion Cannon) and other exploits. 

Happy Hacking

Enjoy.......
