Flood a website with denial of service attack
What is a Denial Of Service Attack?
A denial of service attack (DOS)
is an attack through which a person can render a system unusable or
significantly slow down the system for legitimate users by overloading
the resources, so that no one can
access it.
If an attacker is unable to gain access to a machine, the attacker most
probably will just crash the machine to accomplish a denial of service
attack,this one of the most used method for
website hacking
Types of denial of service attacks
There are several general categories of DoS attacks.Popularly, the attacks are divided into three classes:
bandwidth attacks,
protocol attacks
logic attacks
What is Distributed Denial of Service Attack?
In DDOS attack, The attacker launches the attack using several
machines. In this case, an attacker breaks into several machines, or
coordinates with several zombies to launch an attack against a target
or network at the same time.
This makes it difficult to detect because attacks originate from several IP
addresses.If
a single IP address is attacking a company, it can block that address
at its firewall. If it is 30000 this is extremely difficult.
Damages made By Denial of service 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 broker E*Trade (EGRP) and others having traffic to their sites virtually choked off.
This attack also
recently hit

was brought down by denial of service attack,They tired up there server
so no one can get on log on it.Websites like facebook,ebay etc have
also been victim of this attack.
Now i will show you how you can
flood a website with Denial of service attack.
For this tutorial we will be using one of the most effective and one
of the least known tools called "Low Orbit Ion Cannon", created by
Anonymous members from 4chan.org, this program is one of the best for
DDoS'ing, and I have
successfully used it to DDoS websites. An internet connection as bad as mine (2,500 kb/s) was able to keep a site down
for a day with this program running. Remember that this tool will work best with
high internet speeds,
and try not to go for impossible targets (like Google, Myspace,Yahoo).
LOIC is used on a single computer, but with friends it's enough to
give sites a great deal of downtime.
Prerequisites:
Download LOIC (Low Orbit Ion Cannon). Open up LOIC.
(I am not giving a download link because then i will be accused for exiting hackers,try goggling).
Step 1: Type the target URL in the URL box.
Step 2: Click lock on.
Step 3:
Change the threads to 9001 for maximum efficiency.
Step 4: Click the big button
"IMMA FIRIN MAH LAZAR!"
Feel free to tweak around with these
settings
and play around with the program to get the best performance. Then
minimize and go do whatever you need to do, the program will take
care of the rest!
