Distributed Denial of Service Attack - DDoS attack (Part-1)

Hey guys! Sorry for being away for quite long. Today I am going to post on a very easy but harmful hack.
We can easily take down many sites from this although it is for small period but yet it can suffer a huge loss.
I hope many of you have guessed my topic of today's discussion. Yes its Distributed Denial of Service (DDoS) attack.
We can perform this attack in many ways but today I am posting the tutorial on slowloris but before we start lets see what is DDoS attack.

About: DDoS, fairly called as Denial of Service attack is one of the most powerful attack which is very tough to stop by any of the server although it takes time to perform.
In this we send a huge amount of packets to the port of the site which is open usually it is port 80 or attacks on those port which are open and ready to accept the packets.
These huge amount of packets creates a great traffic in the site and ultimately take it down till the attack is being performed or the server blocks the ip which is sending the packets.

Many of you must be thinking that what will happen if the site goes down for few hours???
Think about the big shopping sites like flipkart, ebay, amazon, etc., if they get down for few hours how much they will suffer a loss. Similarly, if someone attacks on stock exchange then just think how much unthinkable loss can happen in hours.

***Performing DDoS attack is under cyber crime. So think before you act.
Words for white hat hackers: Report the admin of the web page if you find any unimportant open port which is accepting the packets.
Words for programmers: Please check your codes and make sure most of the ports are closed and the codes are properly written and has no open segments.
Words for black hat hackers: Follow the tutorial to take down the site and don't forget to use proxy.

DDoSing via Slowloris:
Step 1: Download and install "active perl" from the link Click here to download Active Perl
Step 2: Download this slowloris script by clicking here Click here to download slowloris and save in any of your desired location and file extension as .pl (this is extension for perl script files). Like I have saved it in C:\downloads\DDOS\slowloris
Step 3: Open cmd by pressing windows+r (run dialog box appears) and then type cmd and hit enter.
Step 4: Go to the location by typing its address.
C:\downloads\DDOS
and press enter
Step 5: Run the slowloris script on the site. Here my target site is www.target-site.com
C:\downloads\DDOS> slowloris.pl -dns www.target-site.com -port 80 -timeout 1 -num 1000 -cache

Here you can change the port number to any other port which is open.

Check the site after few hours. Boom... You have taken it down.
