Computer crime, cybercrime, e-crime, hi-tech crime or electronic crime generally refers to criminal activity where a computer or network is the source, tool, target, or place of a crime. These categories are not exclusive and many activities can be characterized as falling in one or more category. Additionally, although the terms computer crime and cybercrime are more properly restricted to describing criminal activity in which the computer or network is a necessary part of the crime, these terms are also sometimes used to include traditional crimes, such as fraud, theft, blackmail, forgery, and embezzlement, in which computers or networks are used. As the use of computers has grown, computer crime has become more important.

Computer crime can broadly be defined as criminal activity involving an information technology infrastructure, including illegal access (unauthorized access), illegal interception (by technical means of non-public transmissions of computer data to, from or within a computer system), data interference (unauthorized damaging, deletion, deterioration, alteration or suppression of computer data), systems interference (interfering with the functioning of a computer system by inputting, transmitting, damaging, deleting, deteriorating, altering or suppressing computer data), misuse of devices, forgery (ID theft), and electronic fraud.

Computer crime issues have become high-profile, particularly those surrounding hacking, copyright infringement through warez, child pornography, and child grooming. There are also problems of privacy when confidential information is lost or intercepted, lawfully or otherwise.

Generally

Computer crime encompass a broad range of potentially illegal activities. Generally, however, it may be divided into one of two types of categories: (1) crimes that target computer networks or devices directly; (2) crimes facilitated by computer networks or devices, the primary target of which is independent of the computer network or device.

Examples of crimes that primarily target computer networks or devices would include,

Examples of crimes that merely use computer networks or devices would include,

A common example is when a person starts to steal information from sites, or cause damage to, a computer or computer network. This can be entirely virtual in that the information only exists in digital form, and the damage, while real, has no physical consequence other than the machine ceases to function. In some legal systems, intangible property cannot be stolen and the damage must be visible, e.g. as resulting from a blow from a hammer. Where human-centric terminology is used for crimes relying on natural language skills and innate gullibility, definitions have to be modified to ensure that fraudulent behavior remains criminal no matter how it is committed.

A computer can be a source of evidence Even though the computer is not directly used for criminal purposes, it is an excellent device for record keeping, particularly given the power to encrypt the data. If this evidence can be obtained and decrypted, it can be of great value to criminal investigators.

Specific computer crimes

Spam

Spam, or the unsolicited sending of bulk email for commercial purposes, is unlawful to varying degrees. As applied to email, specific anti-spam laws are relatively new, however limits on unsolicited electronic communications have existed in some forms for some time.[1]

Fraud

Computer fraud is any dishonest misrepresentation of fact intended to induce another to do or refrain from doing something which causes loss.[citation needed] In this context, the fraud will result in obtaining a benefit by:

Other forms of fraud may be facilitated using computer systems, including bank fraud, identity theft, extortion, and theft of classified information.

Obscene or offensive content

The content of websites and other electronic communications may be distasteful, obscene or offensive for a variety of reasons. In some instances these communications may be illegal.

Many jurisdictions place limits on certain speech and ban racist, blasphemous, politically subversive, libelous or slanderous, seditious, or inflammatory material that tends to incite hate crimes.

The extent to which these communications are unlawful varies greatly between countries, and even within nations. It is a sensitive area in which the courts can become involved in arbitrating between groups with entrenched beliefs.

Harassment

Whereas content may be offensive in a non-specific way, harassment directs obscenities and derogatory comments at specific individuals focusing for example on gender, race, religion, nationality, sexual orientation. This often occurs in chat rooms, through newsgroups, and by sending hate e-mail to interested parties (see cyber bullying, harassment by computer, stalking, and cyberstalking). Any comment that may be found derogatory or offensive is considered harassment.

Drug trafficking

Drug traffickers are increasingly taking advantage of the Internet to sell their illegal substances through encrypted e-mail and other Internet Technology. Some drug traffickers arrange deals at internet cafes, use courier Web sites to track illegal packages of pills, and swap recipes for amphetamines in restricted-access chat rooms. The rise in Internet drug trades could also be attributed to the lack of face-to-face communication. These virtual exchanges allow more intimidated individuals to more comfortably purchase illegal drugs. The sketchy effects that are often associated with drug trades are severely minimized and the filtering process that comes with physical interaction fades away. Furthermore, traditional drug recipes were carefully kept secrets. But with modern computer technology, this information is now being made available to anyone with computer access.

Cyberterrorism

Government officials and IT security specialists have documented a significant increase in Internet probes and server scans since early 2001. There is a growing concern among federal officials[who?] that such intrusions are part of an organized effort by cyberterrorists, foreign intelligence services, or other groups to map potential security holes in critical systems. A cyberterrorist is someone who intimidates or coerces a government or organization to advance his or her political or social objectives by launching computer-based attack against computers, network, and the information stored on them.

Cyberterrorism in general, can be defined as an act of terrorism committed through the use of cyberspace or computer resources. As such, a simple propaganda in the Internet, that there will be bomb attacks during the holidays can be considered cyberterrorism. At worst, cyberterrorists may use the Internet or computer resources to carry out an actual attack.

As well there are also hacking activities directed towards individuals, families, organised by groups within networks, tending to cause fear among people, demonstrate power, collecting information relevant for ruining peoples' lives, robberies, blackmailing etc.
