Chapter One
Introduction
How can I use
this eBook?
Congratulations! By purchasing this eBook,
you have taken your first step in
the exciting process of becoming a Master
Hacker. The knowledge you acquire from this eBook can be put to use in many
ways:
• With the
ability to think like a hacker, you’ll be able to protect yourself from hackers
attacking you.
• You may
wish to seek a career in Ethical Hacking
– Usually hired by an organization, an ethical hacker uses the same tools and
techniques as a hacker to find and secure vulnerabilities in computer systems.

• Show off
your newfound skills to your friends, and just hack because you want to. It’s
FUN!!
What is a
hacker?
A hacker is
someone who likes to tinker with electronics or computer systems. Hackers like
to explore and learn how computer systems work, finding ways to make them do
what they do better, or do things they weren’t intended to do. There are two
types of hackers:
White Hat – These are
considered the good guys. White hat hackers don’t use their skills for illegal purposes. They usually become Computer
Security experts and help protect people from the Black Hats.
Black Hat – These are considered the bad
guys. Black hat hackers usually use their
skills maliciously for personal gain. They are the people that hack banks,
steal credit cards, and deface websites.
These two
terms came from the old western movies where the good guys wore white hats and
the bad guys wore black hats.
Now if you’re
thinking, “Oh boy! Being a black hat sounds awesome!”, Then I have a question
for you. Does it sound cool to live in a cell the size of your bathroom and be
someone’s butt buddy for many years? That’s what I thought.
Hacker Hierarchy
Script kiddies – These are
the wannabe hackers. They are looked down upon in the hacker community because they are the people that make hackers
look bad. Script kiddies usually have no hacking skills and use the tools
developed by other hackers without any knowledge of what’s happening behind the
scenes.
Intermediate hackers – These
people usually know about computers, networks, and have enough programming knowledge to understand relatively
what a script might do, but like the script kiddies they use pre-developed
well-known exploits (-
a piece of
code that takes advantage of a bug or vulnerability in a piece of software that
allows you to take control of a computer system) to carry out attacks
Elite Hackers – These are the skilled hackers.
They are the ones that write the many
hacker tools and exploits out there. They can break into systems and hide their
tracks or make it look like someone else did it. You should strive to
eventually reach this level.
What does it take to become a hacker?
Becoming
a great hacker isn’t easy and it doesn’t happen quickly. Being creative helps a
lot. There is more than one way a problem can be solved, and as a hacker you
encounter many problems. The more creative you are the bigger chance you have
of hacking a system without being detected. Another huge
quality you
must have is the will to learn because without it, you will get nowhere.
Remember, Knowledge is power. Patience is also a must because many topics can
be difficult to grasp and only over time will you master them.
Chapter Two
Programming
Do I Really Need It?
You might be
asking yourself, do I even need to learn a programming language? The answer to
that is both yes and no. It all depends on what your goals are. Nowadays, with
all the point and click programs out there, you can be a fairly good ethical
hacker without knowing any programming. You can do some effective hacking if
you understand all of the security tools very well. Even if you understand what’s
going on in the background of these programs, most people will still classify
you as a script kiddie. Personally I think you should learn some programming.
Even if it’s the very basics, it’ll give you a much better understanding of
what’s going on. Also, once you learn how to program well, you’ll be able to
develop your own exploits, which is great in many ways:
1.
You’ll be considered an elite hacker.
2.
Imagine a black hat discovers a vulnerability and codes
an exploit for it that no one else knows about. The black hat would be able to
take down thousands of machines before anyone discovers and patches the
vulnerability.
3.
You will feel so much more satisfied having created
your own program or exploit. I promise you this.
So
my advice is, don’t settle for being a point and click hacker. Take some time
to understand even just the basics of programming and an entire new world of
hacking will open up to you.
Where should I
start?
Many people
finally decide that they are going to begin learning a programming language,
but don’t know where to start. I believe that before you begin to learn a
programming language, you should first master HTML (HyperText Markup Language).
HTML is part of what makes up all of the website pages you see on the internet.
HTML is very easy to learn and it’ll get you used to looking at source code.
10
From there I would suggest starting your programming life
with C. C is one of the most popular languages, and it is what makes up the
majority of the exploits out there today. C also makes up some of the most
powerful hacking programs and viruses that are out there today.
Best way to learn
So how should I go about learning the programming
language of my choice?
1.
Purchase a beginners book on your programming
language. Before you choose the book, make sure you read the reviews to make
sure it’s a good choice.
2.
It is important that once you begin learning the
programming language through your book, you don’t take big breaks. Taking long
breaks will cause you to forget things you learned in the beginning that apply
to the rest of the book.
3.
Do ALL of
the practice problems provided in the book. The only way you will become better
is by applying what you learn.
4.
When something difficult comes up or something that
makes no sense to you, don’t avoid or skip it. Instead embrace it! This is how
you actually learn. If you still don’t understand it after going over it
multiple times, find someone that can help you.
5.
Join a programming forum. Search for a website on your
programming language that has a large user base. There will be many
professionals on there that will be able to help you when you get stuck.
6.
Practice. Practice Practice. Think of ideas for fun
programs that you could make and program them!
