Preface 

Computer hacking is the practice of altering computer hardware and software to carry out a goal outside of the creator‘s 
original intention. People who slot in computer hacking actions and activities are often entitled as hackers. 

The majority of people assume that hackers are computer criminals. They fall short to identify the fact that criminals and 
hackers are two entirely unrelated things. Media is liable for this. Hackers in realism are good and extremely intelligent 
people, who by using their knowledge in a constructive mode help organizations, companies, government, etc. to secure 
credentials and secret information on the Internet.

Years ago, no one had to worry about Crackers breaking into their computer and installing Trojan viruses, or using your 
computer to send attacks against others. Now that thing have changed, it's best to be aware of how to defend your 
computer from damaging intrusions and prevent black hat hackers. Rampant hacking is systematically victimizing 
computers around the world. This hacking is not only common, but is being executed without a flaw that the attackers 
compromise a system, steal everything of value and entirely rub out their pathway within 20 minutes. So, in this Book you 
will uncover the finest ways to defend your computer systems from the hackers 

This Book is written by keeping one object in mind that a beginner, who is not much familiar regarding computer hacking, 
can easily, attempts these hacks and recognize what we are trying to demonstrate. Here we have incorporated the best 
ethical hacking articles in this volume, covering every characteristic linked to computer security. 

After Reading this book you will come to recognize that how Hacking is affecting our every day routine work and can be 
very hazardous in many fields like bank account hacking etc. Moreover, after carrying out this book in detail you will be 
capable of understanding that how a hacker hacks and how you can defend yourself from these threats.

So Take care of yourself and Defend Yourself By hacking the hacker and be safe after that. So If you know how to hack a 
hacker then you can know how to prevent the hacker.

1. Concept of Ethical Hacking 

Hacking 

 The Art of exploring various security breaches is termed as Hacking.

 Computer Hackers have been around for so many years. Since the Internet became widely used in the World, We 

have started to hear more and more about hacking. Only a few Hackers, such as Kevin Mitnick, are well known.

 In a world of Black and White, it’s easy to describe the typical Hacker. A general outline of a typical Hacker is an 

Antisocial, Pimple-faced Teenage boy. But the Digital world has many types of Hackers.

 Hackers are human like the rest of us and are, therefore, unique individuals, so an exact profile is hard to outline. 

The best broad description of Hackers is that all Hackers aren’t equal. Each Hacker has Motives, Methods and
Skills. But some general characteristics can help you understand them. Not all Hackers are Antisocial, Pimple-
faced Teenagers. Regardless, Hackers are curious about Knowing new things, Brave to take steps and they are 
often very Sharp Minded.

Hacker 


Hacker is a word that has two meanings:

 Traditionally, a Hacker is someone who likes to play with Software or Electronic Systems. Hackers enjoy Exploring 

and Learning how Computer systems operate. They love discovering new ways to work electronically.

 Recently, Hacker has taken on a new meaning — someone who maliciously breaks into systems for personal gain. 

Technically, these criminals are Crackers as Criminal Hackers. Crackers break into systems with malicious 
intentions.

 They do it for Personal gain, Fame, Profit and even Revenge. They Modify, Delete and Steal critical information, 

often making other people's life miserable.

 Hacking has a lot of meanings depending upon the person’s knowledge and his work intentions. Hacking is an Art 

as well as a Skill. Hacking is the knowledge by which one gets to achieve his Goals, anyhow, using his Skills and 
Power.

 Most people associate Hacking with breaking law, therefore calling all those guys who engage in hacking activities 

to be criminals. We agree that there are people out there who use hacking techniques to break the law, but
hacking is not really about that. In fact, hacking is more about following the law and performing the steps within 
the limits.

Hacker vs. Cracker 

What Is the Difference Between a Hacker and a Cracker?


Many articles have been written about the difference between Hackers and crackers, which attempt to correct 
public misconceptions about hacking. For many years, media has applied the word Hacker when it really means
Cracker. So the public now believe that a Hacker is someone who breaks into computer systems and steal 
confidential data. This is very untrue and is an insult to some of our most talented Hackers.
There are various points to determine the difference between Hackers and crackers


Definition - A Hacker is a person who is interested in the working of any computer Operating system. Most often, 
Hackers are programmers. Hackers obtain advanced knowledge of operating systems and programming 
languages. They may know various security holes within systems and the reasons for such holes. Hackers 

 
Hacking For Beginners – Manthan Desai
2010

w w w . h a c k i n g t e c h . c o . t v
Page 13

constantly seek further knowledge, share what they have discovered, and they never have intentions about 
damaging or stealing data.


Definition - A Cracker is a person who breaks into other people systems, with malicious intentions. Crackers gain 
unauthorized access, destroy important data, stop services provided by the server, or basically cause problems for
their targets. Crackers can easily be identified because their actions are malicious.


Whatever the case, most people give Hacker a negative outline. Many malicious Hackers are electronic thieves.
Just like anyone can become a thief, or a robber, anyone can become a Hacker, regardless of age, gender, or 
religion. Technical skills of Hackers vary from one to another. Some Hackers barely know how to surf the Internet, 
whereas others write software that other Hackers depend upon.

Types of Hacker 

 Let’s see the categories of Hackers on the basis on their knowledge.

Coders


The Real Hackers are the Coders, the ones who revise the methods and create tools that are available in the 
market. Coders can find security holes and weaknesses in software to create their own exploits. These Hackers 
can use those exploits to develop fully patched and secure systems.


Coders are the programmers who have the ability to find the unique vulnerability in existing software and to 
create working exploit codes. These are the individuals with a deep understanding of the OSI Layer Model and 
TCP/IP Stacks.

Admins


Admins are the computer guys who use the tools and exploits prepared by the coders. They do not develop their 
own techniques, however they uses the tricks which are already prepared by the coders. They are generally 
System Administration, or Computer Network Controller. Most of the Hackers and security person in this digital
world come under this category.


Admins have experience with several operating systems, and know how to exploit several existing vulnerabilities. 
A majority of Security Consultants fall in this group and work as a part of Security Team.

Script Kiddies


Next and the most dangerous class of Hackers is Script kiddies, They are the new generation of users of computer 
who take advantage of the Hacker tools and documentation available for free on the Internet but don’t have any
knowledge of what’s going on behind the scenes. They know just enough to cause you headaches but typically are 
very sloppy in their actions, leaving all sorts of digital fingerprints behind. Even though these guys are the teenage
Hackers that you hear about in the news media, they need minimum skills to carry out their attacks.


Script Kiddies are the bunnies who use script and programs developed by others to attack computer systems and 
Networks. They get the least respect but are most annoying and dangerous and can cause big problems without
actually knowing what they are doing.

 Types of Hackers on the basis of activities performed by them.

Page 14

White Hat Hacker


A White Hat Hacker is computer guy who perform Ethical Hacking. These are usually security professionals with
knowledge of hacking and the Hacker toolset and who use this knowledge to locate security weaknesses and 
implement counter measures in the resources.


They are also known as an Ethical Hacker or a Penetration Tester. They focus on Securing and Protecting IT 
Systems.

Black Hat Hacker


A Black Hat Hacker is computer guy who performs Unethical Hacking. These are the Criminal Hackers or Crackers 
who use their skills and knowledge for illegal or malicious purposes. They break into or otherwise violate the 
system integrity of remote machines, with malicious intent.


These are also known as an Unethical Hacker or a Security Cracker. They focus on Security Cracking and Data
stealing.

Grey Hat Hacker


A Grey Hat Hacker is a Computer guy who sometimes acts legally, sometimes in good will, and sometimes not. 
They usually do not hack for personal gain or have malicious intentions, but may or may not occasionally commit 
crimes during the course of their technological exploits.


They are hybrid between White Hat and Black Hat Hackers.

Ethical Hacking  

 Ethical Hacking is testing the resources for a good cause and for the betterment of technology. Technically Ethical 

Hacking means penetration testing which is focused on Securing and Protecting IT Systems.

Hactivism 

 Another type of Hackers are Hacktivists, who try to broadcast political or social messages through their work. A 

Hacktivist wants to raise public awareness of an issue. Examples of hacktivism are the Web sites that were 
defaced with the Jihad messages in the name of Terrorism.

Cyber Terrorist 

 There are Hackers who are called Cyber Terrorists, who attack government computers or public utility 

infrastructures, such as power stations and air-traffic-control towers. They crash critical systems or steal classified 
government information. While in a conflict with enemy countries some government start Cyber war via Internet.

Why Hackers Hack? 

 The main reason why Hackers hack is because they can hack. Hacking is a casual hobby for some Hackers — they 

just hack to see what they can hack and what they can’t hack, usually by testing their own systems. Many Hackers 
are the guys who get kicked out of corporate and government IT and security organizations. They try to bring 
down the status of the organization by attacking or stealing information.

 The knowledge that malicious Hackers gain and the ego that comes with that knowledge is like an addiction. 

Some Hackers want to make your life miserable, and others simply want to be famous. Some common motives of
malicious Hackers are revenge, curiosity, boredom, challenge, theft for financial gain, blackmail, extortion, and 
corporate work pressure.

 Many Hackers say they do not hack to harm or profit through their bad activities, which helps them justify their 

work. They often do not look for money full of pocket. Just proving a point is often a good enough reward for 
them.

Prevention from Hackers 

 What can be done to prevent Hackers from finding new holes in software and exploiting them?

 Information security research teams exist—to try to find these holes and notify vendors before they are

exploited. There is a beneficial competition occurring between the Hackers securing systems and the Hackers 
breaking into those systems. This competition provides us with better and stronger security, as well as more 
complex and sophisticated attack techniques.

 Defending Hackers create Detection Systems to track attacking Hackers, while the attacking Hackers develop

bypassing techniques, which are eventually resulted in bigger and better detecting and tracking systems. The net 
result of this interaction is positive, as it produces smarter people, improved security, more stable software, 
inventive problem-solving techniques, and even a new economy.

 Now when you need protection from Hackers, whom you want to call, “The Ethical Hackers”. An Ethical Hacker 

possesses the skills, mindset, and tools of a Hacker but is also trustworthy. Ethical Hackers perform the hacks as 
security tests computer systems.

 Ethical Hacking — also known as Penetration Testing or White-Hat Hacking —involves the same Tools, Tricks and 

Techniques that Hackers use, but with one major difference:

 Ethical hacking is Legal.

 Ethical hacking is performed with the target’s permission. The intent of Ethical Hacking is to discover 

vulnerabilities from a Hacker’s viewpoint so systems can be better secured. Ethical Hacking is part of an overall 
information Risk Management program that allows for ongoing security improvements. Ethical hacking can also 
ensure that vendors’ claims about the security of their products are legitimate.

 As Hackers expand their knowledge, so should you. You must think like them to protect your systems from them. 

You, as the ethical Hacker, must know activities Hackers carry out and how to stop their efforts. You should know 
what to look for and how to use that information to thwart Hackers’ efforts.

 You don’t have to protect your systems from everything. You can’t.

The only protection against everything is to unplug your computer systems and lock them away so no 
one can touch them—not even you.
