DDoS
is when a person or many people attempt to bring down a server or website by
overloading the server with requests. When this is done it essentially prevents
other people for accessing the website or service.
--------------------------------------------------------------------------
What
to expect?
Now
if you attempt this attack by yourself there are a few outcomes that you could
expect:
The
first outcome is if you attempt to deny service to a big website such as Google
or Wikipedia you won’t even make a dent and they will shrug you off like you
were never there.
The
second outcome is if you attempt to deny service to a medium sized website such
as small to medium sized companies who host their own websites. You may slow
them down or even take them down for a few minutes, but eventually all will be
rectified and they will hopefully know better next time. [How to prevent DDoS
attacks article coming soon]
The
third outcome is if you attempt to deny service to a small website, something
like your friend’s website or a personal website. These can be taken down very
easy depending on your own connection.
There
are many other things that can happen but these would be the main ones, DDoS
attacks are more likely to succeed if you are doing them at the same time or set
up botnet or zombie computers, more on them in my forthcoming articles.

Big
Attacks in the past:
On
March 18th the largest DDoS attack occurred, this attack was against
Spamhaus, A not-for-profit anti-spam organisation. It began at 10Gbps and
quickly escalated only to peak at 90Gbps. All was quiet for a few days until
March 22nd when the attack resumed and peaks at 120Gbps. This was
the biggest(at the time of writing) attack ever preformed...
But
did it “break the internet” like it was intended? No, Spamhaus had measures in
place to prevent such attacks which kept the systems online, Now not to say
that it wasn't a valiant effort but unfortunately this time it didn't succeed.

How
to attack using DDoS?
Most
people use a program to perform their DDoS attacks these days, but I’ll show
you that in a moment, the old way to do things would be as follows:
1. Open your command line
2. Type: "ping [website or IP]
-l 5120 -n 100000 -w 1"
The
website or IP allows you to type one or the other, so for instance it could be www.google.com
or 74.125.24.147.
The “5120”
is the size of the packet your want to send, in this example it is 5KB, this
must not surpass your own capabilities or you could deny your service and not
anyone else’s.
Then
the “100000” is the amount of packets you wish to send to the target, this can
be as many or as little as you want, the more you send the longer the attack
will last.
Finally
the “–w 1” is the amount of time you wish to wait before the next packet is
sent, this can also be altered to suit the individual attack.
Now
that the basic ways are covered I will move onto the programs that people use,
there are many programs out there that can be used but be warned that a lot of
these programs contain backdoors which will allow the backdoor maker access to
your computer, you are best to get clean programs from sources. Some programs
will appear to be infected according to your anti-virus but that is expected,
and is up to your own judgment whether you wish to use it or not.
A lot
of people swear by the LOIC or the Low Orbit Ion Cannon as it was so funnily
called. The LOIC is a program created by anonymous members from the website www.4chan.org.
All that is needed to do is you type in the website name that you wish to
attack, lock on, set thread count(9001 max) and then hit the “IMMA CHARGIN MAH
LAZAR!” button and the attack will be started.
Any
attack has a greater success rate if carried out simultaneously by multiple
people. This can be accomplished by getting friends to do this with you or by
using botnets. Also when carrying out these attacks it is recommended to use a
VPN either paid or free.
