Hacker and Cracker

These are the people who violate computer security. A Hacker is the one who have enough knowledge to break into computer system, although he or she does not cause any harm to the computer system or the organization. A Cracker is a computer thief who breaks into a computer system with wrong intentions that is for stealing passwords, mails, messages, files, programs, images, videos etc for their own entertainment or benefit.

• A hacker is a person intensely interested in the arcane and recondite workings of any computer operating system. Hackers are most often programmers. As such, hackers obtain advanced knowledge of operating systems and programming languages. They might discover holes within systems and the reasons for such holes. Hackers constantly seek further knowledge; freely share what they have discovered, and never intentionally damage data.
• A cracker is one who breaks into or otherwise violates the system integrity of remote machines with malicious intent. Having gained unauthorized access, crackers destroy vital data; deny legitimate users service, or cause problems for their targets. Crackers can easily be identified because their actions are malicious.

 Hackers can help a firm or company by informing them regarding the lapses in the system of that company or firm.  Hackers can also help the security system of a country by finding the lapses in the system and fulfilling them. For example, the password of some financially sound company in a bank can be steal or broken by hacker but they do not transfer money. On the other hand, Cracker can transfer the money and cause financial damage.

For example, in late 2013, an A.T.M. in Kiev started dispensing cash at seemingly random times of day. No one had put in a card or touched a button. Cameras showed that the piles of money had been swept up by customers who appeared lucky to be there at the right moment. Also in 1991 a major U.S automobile company lost $500 million worth of designs future cars, due to security breach at research facility and suffered in the market because its designs fell into the hands of its competitors.

Hackers as opposite to crackers are basically thrill seekers who use information technology rather than the fast cars. They spend their time learning how systems work at a deep level and exploit this info to roam the information, regular meetings. A diffuse group of people often called hackers has been characterized as unethical, illegal not responsible, and a serious danger to society for actions related to breaking into computer systems….

Hackers are learners and explorer who want to help rather than cause damage, and who often have very high standards of behavior.

Even though are many definitions of what a true hacker is, there is one universal belief of what hacker are not amongst the people who believe that there is a fundamental difference between hackers and crackers.
