WHAT HACKERs DO

  WHAT HACKER DO

Thanks to the media, the word "hacker" has gotten a bad reputation. The word summons up thoughts of malicious computer users finding new ways to harass people, defraud corporations, steal information and maybe even destroy the economy or start a war by infiltrating military computer systems. While there's no denying that there are hackers out there with bad intentions, they make up only a small percentage of the hacker community.

The term computer hacker first showed up in the mid-1960s. A hacker was a programmer -- someone who hacked out computer code. Hackers were visionaries who could see new ways to use computers, creating programs that no one else could conceive. They were the pioneers of the computer industry, building everything from small applications to operating systems. In this sense, people like Bill Gates, Steve Jobs and Steve Wozniak were all hackers -- they saw the potential of what computers could do and created ways to achieve that potential.

A unifying trait among these hackers was a strong sense of curiosity, sometimes bordering on obsession. These hackers prided themselves on not only their ability to create new programs, but also to learn how other programs and systems worked. When a program had a bug -- a section of bad code that prevented the program from working properly -- hackers would often create and distribute small sections of code called patches to fix the problem. Some managed to land a job that leveraged their skills, getting paid for what they'd happily do for free.

As computers evolved, computer engineers began to network individual machines together into a system. Soon, the term hacker had a new meaning -- a person using computers to explore a network to which he or she didn't belong. Usually hackers didn't have any malicious intent. They just wanted to know how computer networks worked and saw any barrier between them and that knowledge as a challenge.­

In fact, that's still the case today. While there are plenty of stories about malicious hackers sabotaging computer systems, infiltrating networks and spreading computer viruses, most hackers are just curious -- they want to know all the intricacies of the computer world. Some use their knowledge to help corporations and governments construct better security measures. Others might use their skills for more unethical endeavors.

In this article, we'll explore common techniques hackers use to infiltrate systems. We'll examine hacker culture and the various kinds of hackers as well as learn about famous hackers, some of whom have run afoul of the law.

In the next section, we'll look at hackers' tricks of the trade.

SUPER PHREAK

Before computer hackers, curious and clever individuals found ways to manipulate the phone system in a phenomenon called phreaking. Through phreaking, these individuals found ways to make long distance calls for free or sometimes just played pranks on other telephone users.

WHAT IS HACKING

       WHAT IS HACKING

  

In computer networking, hacking is any technical effort to manipulate the normal behavior of network connections and connected systems. A hacker is any person engaged in hacking. The term "hacking" historically referred to constructive, clever technical work that was not necessarily related to computer systems. Today, however, hacking and hackers are most commonly associated with malicious programming attacks on the Internet and other networks.

Origins of Hacking

M.I.T. engineers in the 1950s and 1960s first popularized the term and concept of hacking. Starting at the model train club and later in the mainframe computer rooms, the so-called "hacks" perpetrated by these hackers were intended to be harmless technical experiments and fun learning activities.

Later, outside of M.I.T., others began applying the term to less honorable pursuits. Before the Internet became popular, for example, several hackers in the U.S. experimented with methods to modify telephones for making free long-distance calls over the phone network illegally.

Hacking on computer networks is often done through scripts or other network programming. These programs generally manipulate data passing through a network connection in ways designed to obtain more information about how the target system works. Many such pre-packaged scripts are posted on the Internet for anyone, typically entry-level hackers, to use. More advanced hackers may study and modify these scripts to develop new methods. A few highly skilled hackers work for commercial firms with the job to protect that company's software and data from outside hacking.

Cracking techniques on networks include creating worms, initiating denial of service (DoS) attacks, or in establishing unauthorized remote access connections to a device.

  As computer networking and the Internet exploded in popularity, data networks became by far the most common target of hackers and hacking.

Hacking vs. Cracking

Malicious attacks on computer networks are officially known as cracking, while hacking truly applies only to activities having good intentions. Most non-technical people fail to make this distinction, however. Outside of academia, its extremely common to see the term "hack" misused and be applied to cracks as well.
