HACKERS AND CRACKERS(by Mario Novakovic-1, G11)

Many people think that word «hacker» refers to a person who breaks into systems to damage it or for the purpose of getting illegitimate access to resources. But that's not true.Those people are «crackers». In this article I will describe you the differences between hackers and crackers.

HACKERS

There are many definitions for the hackers: 1)A person who enjoys exploring the details of programmable systems and how to stretch their capabilities. 2)A person who is good at programming quickly. 3)One who enjoys the intellectual challenge of creatively overcoming or circumventing limitations 4)An expert at a particular program, or one who frequently does work using it or on it; as in a «UNIX hacker»

As we see from these definitions a hacker is someone who just wants to know everything from a system just for the joy of it. They are experienced programmers, often working in C or C++, who "hack" solutions to complex programming problems. Hackers, for instance, created Linux and Apache, two huge Open Source programming projects.


CRACKERS

Crackers are people to gain unauthorized access to a computer system, often on a network; bypasses passwords or licenses in computer programs. A cracker can be doing this for profit, maliciously, for some altruistic purpose or cause, or because of the challenge. Crackers do not seek knowledge for the knowledge itself, but to show off that they can break into a certain system or create a nasty virus.


CONCLUSION

From this article we can see that the basic distinction between hackers and crackers is this: Hackers build things, crackers break them.

Hackers & Crackers

Hackers and crackers are persons who know computers, networks and their functions very well and do the things which can be god or bad for the others in that area of technology. A lot of people think that word «hacker» refers to a person who breaks into systems to damage it or for the purpose of getting illegitimate access to resources. Actually people constantly confuses hackers with crackers. Crackers are those who do the bad things. Hacker decide will he behave like a cracker or like a real god hacker. Hereafter we will describe the differences between hackers and crackers.

Hackers

There are many definitions for the hackers. The most simple is to say that hacker is a skilled person who uses his talents and knowledge to modify the software or hardware of a computer system. Hacker is often an expert in programming and enjoys in learning and seeking the details of programmable systems and how to extend their features. Hacker is also a specialist at a particular operating system, as in "a Unix hacker". Hackers build, rebuild and modify software and electronic hardware to make it better, faster, easier for use, add new features or to make it do something which wasn’t possible before.

From all of that we can see, a hacker is someone who just wants to know everything about a system just for the joy of it. As experienced programmers hackers use programming languages like C or C++, who "hack" solutions to complex programming problems. Hackers, for instance, created Linux and Apache, two huge Open Source programming projects.

There are three major categories of hackers:

  • White hat hackers – also known as Ethical Hackers. They work to identify weaknesses in computer systems so they can make better systems which will be more safe against malicious attacks
  • Gray hat hackers – refers to hackers who sometimes do legal acts in good will and sometimes not
  • Black hat hackers – also known as crackers. They attack computer systems from the different reasons like fun, political motivations, profit etc.

The last true hacker was Richard Stallman.


Richard Matthew Stallman

Richard Stallman is American computer technician and political activist, known as the founder of the movement for free software. He is a programmer of legendary Emacs text editor, founder and head of the Free Software Foundation and author of the GNU General Public License. Stallman has received many awards for his work and some of them are MacArthur Foundation Fellowship (1990), The Takeda Techno-Entrepreneurship Award (2001) etc.

Crackers

Cracker is a person who is liable for destroying vital data, causing havoc throughout the Internet, or cause problems for their targets. They often do illegal actions on a network such as cracking passwords in programs and websites or breaking into networks. Cracker’s actions are malicious and they can be doing this for profit, for some altruistic purpose or cause, or because of the challenge.

Cracker is a person with a larger lever of knowledge in computer science and there are two main types of them:

  1. expert crackers – the individuals who locate new security holes and frequently write programs that exploit them
  2. script kiddie – experts who are using other programs so they can deface web pages and attack computes systems

Some well known crackers are John Draper, Mark Abene, Kevin Mitnick, Kevin Poulsen and Vladimir Levin.


Kevin David Mitnick

Kevin Mitnick is one of the most famous hacker in the world and is also known under the nickname "Condor". He was arrested in 1995. because of alleged burglaries in the Tsutomu Shimomura’s computer, an expert for security computer system. He published his credit card number and was captured in a cooperation of FBI and the Shimomure. Their conflict was observed as one of the most interesting stories about the hacker attacks in history.

Conclusion

People should known that hackers are not crackers. Basic distinction between hackers and crackers is that hackers build things and crackers break them. They have similar level of knowledge but different aims.

Hackers & Crackers introduction

If you have been troubled with this question, here is an answer to it: Hacker and cracker - what is the difference? The difference is huge and this text will try to help you differ them and explain them to you. Hackers and crackers are persons who know computers, networks and their functions very well and do the things which can be good or bad for the others in that area of technology, in other words they are computer experts. A lot of people, when they hear the word «hacker», instantly think of "its" negative meaning, which is a person who breaks into systems to damage them or to get the illegitimate access to resources from them. Actually, people constantly confuse hackers with crackers. Crackers are those who make the damage.

Hackers

In the beginning the term hacker meant expert for programming and solving problems with the help of a computer. Later the term hacker indicated a person who breaks into computer systems to damage them or to get the illegitimate access to resources from them, but experts prefer to call such a person a cracker. Hacker is often an expert in programming who enjoys in learning and seeking the details of programmable systems and the way to extend their features. Hacker is also a specialist at a particular operating system, such as in "a Unix Hacker". Hackers build, rebuild and modify software and electronic hardware to make it better, faster, easier for use, add new features or to make it work in the way that they want it to work.

From all of that we can see, a hacker is someone who just wants to know everything about a system just for the joy of it. As experienced programmers hackers use programming languages like C or C++, who "hack" solutions to complex programming problems. Hackers, for instance, created Linux and Apache, two huge Open Source programming projects.

The last true hacker was Richard Stallman.

History of hackers

The first computer hackers appeared in 60's in MIT. They wanted to "hack" (improve) the electronical trains and switches to make them work better and faster. Some of the students used their skills on the new computer system that was being developed in MIT.

Ancestral hackers were called phreakers. It is a mix of words phone hackers and freaks. The first hacking was carried out in the phone networks. They were producing various types of tones to "hack" phone lines and to establish calls to where ever they wanted, free of cost. The most famous phreaker was John Draper, a.k.a. Captain Crunch.

He published his credit card number and was captured in a cooperation of FBI and the Shimomure. Their conflict was observed as one of the most interesting stories about the cracker attacks in history. When he was in prison guards refused to give him a calculator because they were afraid that he could hack the prison system. He wrote two famous books and today he is now a expert for a computer security.

Conclusion

People should known that hackers are not crackers. Basic difference between hackers and crackers is that hackers build things and crackers break them. They have similar level of knowledge but different aims. The world without hackers would be boring, predictable and monotone.
