Hello Green Hackers Readers....
In This
Post We Know About Advance Level Of Dos Attack Its Known As DDoS Attack. In
Some Of My Last Post We Discuss About DENIAL OF SERVICE (DOS) ATTACK |BASICS & DENIAL OF SERVICE (DOS) ATTACK |
TYPES
So Let's Start....
Distributed Denial Of Service (DDoS) Attack
is large scale DoS attack
conducted with help of zombie systems or botnets on vulnerable target systems.
Indirectly we can say a DDoS
is launched via huge network of compromised systems. DDoS attack uses many computers to launch a coordinated DoS attack against one or more
target.
Using client/server technology (same as we do it in RAT clients), the attacker is able to multiply the effectiveness of the Denial of Service significantly by harnessing the resources of multiple computers to serve for attack. In most of the cases the zombie system user never comes to know about his/her system is performing a DoS Attack since an attacker can put condition to be low on bandwidth usage per zombie.

The victims compromised for
performing an attack are known as “secondary
victim” where as the target on whom attack will be performed is known as
“primary victim”. An attacker
generally gains administrative privilege on secondary targets to launch attack
on primary target. Once attacker gains administrative privilege on secondary
victim, he/she uploads DDoS
program or script to launch an attack on primary victim. If an attacker has
network of 30000 plus zombies then launched attack is nearly impossible to
counter because number of IP address is too much for a single server to handle
per second. DDoS are
dangerous because they can even pull down very big hosts like yahoo and bing to
their feet.
Most organizations secure themselves
with a firewall but a firewall does not really guarantee against DDoS. A very good but badly
administrated firewall can even lead to fall down of service. Conducting a DDoS attack is much simple than
it appears if you already have thousands of compromised system. In fact in most
cases you don't even need already created tools you can manually create your
own tools if you have little programming knowledge of C and C++ and little
about windows and Linux commands. In future posts I ll show you how you can
create your own script to launch a DDoS
attack.
Following are steps involved in conducting DDoS
attack:
1. Compromise Many systems using RAT
clients or botnets.
2. Write a program or script that
can conduct attack
3. Trigger Zombies for attack
4. Don’t stop until the target is
down.
Dear Visitors in my upcoming post we will discuss about BOTNETS and RAT's used for performing DDoS Attack..
Stay With Us..
Enjoy DDoS .......
