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.

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. 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, * Malware and malicious code
* Denial-of-service attacks

Examples of crimes that merely use computer networks or devices would include, * Cyber stalking
* Fraud and identity theft

* Information warfare
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. In...
