How To Perform DOS Attack On A Website By Ry4n h4x0r
DOS (Denial Of Service) attack is one of the most powerful attack that is capable of crashing web servers. In this attack, attacker sends fake requests to server and floods its request queue with millions of Fake requests. In this way, server will not be able to handle valid request by a valid user. DOS attack becomes more popular when it is performed by millions of computer simultaneously on a single target. This is called Distributed Denial Of Server (DDOS) attack. DDOS attack is millions times more popular that DOS attack and its strength depends on the number of systems attending the attack.
There are many DOS attacking tools are available which can be found here.
But LOIC (Low Orbit Ion Cannon) is the best tool for DDOS attack and it is also used by most popular hacker group annonymous. There are two versions of this tool. One is the original binary version of the tool and other is the web based version called JS LOIC.
The best thing about this tool is that the tool does not require any kind of technical knowledge. It is so simple iin use. Just specify the the website and click on the attack button.
How to Use this tool and perform DOS attack on a website:
This tool is available for free. Download it from Sourceforge.
At the top of the tool, there are two options. One for URL and other for IP. You can use any one. Enter the URL of the website which you want to take down. Now click on Lock On button. After that you are ready to attack on the website. Then, select attack method (TCP, UDP or HTTP).
Step 3:Now click on big button “IMMA CHARGIN MAH LAZER.” and start the attack.
Now see the bottom of the tool where you will find 5 fields under Attack status. When you will start attack, you will see that the number in Requested fields are increasing rapidly. This number show how many requestes have been send to website server.
But the important field is "Faild." If you see the increment in this field, it means attack has been working fine. It shows that server has stopped responding to the request. In other way, you can say that server is down. :P
How to Use LOIC and Perform DDOS attack
Windows version of LOIC has a feature called HIVEMIND. This feature allows users to connect other systems on IRC server. In this way, attacker can collect more people in this attack and make it distributed over the internet.
To run this tool in HIVEMIND mode run this tool with command prompt with this command.
LOIC.exe /hivemind irc.server.address
After running the above command, your LOIC client will connect to irc://irc.server.adress:6667/loic
To run this tool in hidden mode, use this command
LOIC.exe /hidden /hivemind irc.server.address
In hidden mode, it will run without any visible GUI.
