Hacking

Hacking Is getting data  from information from someones computer secretly .It require some basic knowledge of programming language but most of  all  you require to know  the history of  hacking.

While breaching privacy to detect cybercrime works well when the crimes involve the theft and misuse of information, ranging from credit card numbers and personal data to file sharing of various commodities—music, video, or child pornography—what of crimes that attempt to wreak havoc on the very workings of the machines that make up the network? The story of hacking actually goes back to the 1950s, when a group of phreaks (short for “phone freaks”) began to hijack portions of the world’s telephone networks, making unauthorized long-distance calls and setting up special “party lines” for fellow phreaks. With the proliferation of computer bulletin board systems (BBSs) in the late 1970s, the informal phreaking culture began to coalesce into quasi-organized groups of individuals who graduated from the telephone network to “hacking” corporate and government computer network systems.

Although the term hacker predates computers and was used as early as the mid-1950s in connection with electronic hobbyists, the first recorded instance of its use in connection with computer programmers who were adept at writing, or “hacking,” computer code seems to have been in a 1963 article in a student newspaper at theMassachusetts Institute of Technology (MIT). After the first computer systems were linked to multiple users through telephone lines in the early 1960s, hacker came to refer to individuals who gained unauthorized access to computer networks, whether from another computer network or, as personal computers became available, from their own computer systems. Although it is outside the scope of this article to discuss hacker culture, most hackers have not been criminals in the sense of being vandals or of seeking illicit financial rewards. Instead, most have been young people driven by intellectual curiosity; many of these people have gone on to become computer security architects. However, as some hackers sought notoriety among their peers, their exploits led to clear-cut crimes. In particular, hackers began breaking into computer systems and then bragging to one another about their exploits, sharing pilfered documents as trophies to prove their boasts. These exploits grew as hackers not only broke into but sometimes took control of government and corporate computer networks.

One such criminal was Kevin Mitnick, the first hacker to make the “most wanted list” of the U.S. Federal Bureau of Investigation (FBI). He allegedly broke into the North American Aerospace Defense Command (NORAD) computer in 1981, when he was 17 years old, a feat that brought to the fore the gravity of the threat posed by such security breaches. Concern with hacking contributed first to an overhaul of federal sentencing in the United States, with the 1984 Comprehensive Crime Control Act and then with the Computer Fraud and Abuse Act of 1986.

In 2001 hackers cost U.S. firms approximately $455 million; in 2003 the total fell to roughly $202 million as firms instituted better security measures. Earlier, in 2000 an “unauthorized intruder” stole eight million credit card numbers from the United States, Canada, the United Kingdom, Japan, and Thailand. The scale of such crimes is among the most difficult to assess, however, because the victims often prefer not to report the crimes—sometimes out of embarrassment or fear of further security breaches. Officials estimated that hacking cost the world economy roughly $2.5 billion in 2000. Hacking is not always an outside job—a related criminal endeavour involves individuals within corporations or government bureaucracies deliberately altering database records for either profit or political objectives. The greatest losses stem from the theft of proprietary information, sometimes followed up by the extortion of money from the original owner for the data’s return. In this sense, hacking is old-fashioned industrial espionage by other means
