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.

•  That’s not the best approach to information security. What’s important is to protect your systems from knownVulnerabilities and common Hacker attacks.
•  It’s impossible to overcome all possible vulnerabilities of your systems. You can’t plan for all possible attacks —

especially the ones that are currently unknown which are called Zero Day Exploits. These are the attacks which
are not known to the world. However in Ethical Hacking, the more combinations you try — the more you test
whole systems instead of individual units — the better your chances of discovering vulnerabilities.

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.

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 Hacker 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

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 correctpublic misconceptions about hacking.
•  For many years, media has applied the word Hacker  when it really mean 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 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.

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 andSkills. But some general characteristics can help you understand them. Not all Hackers are Antisocial, Pimplefaced
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 Exploringand 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, any how, using his Skills and Power.

•  Most people associate Hacking with breaking law, therefore calling all those guys who engage in hacking activitiesto 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 withinthe limits.
