The Internet provides instant global communication between and among individuals and institutions. Used criminally, this can facilitate stalking, money laundering, fraud, larceny, and various types of theft. Relatively new ICT's permit criminals anonymity, a broadening of the pool of potential victims, and an inexpensive and accessible tool for committing many types of crimes. This article discusses how new ICT's maybe the subject of a crime, the object of a crime, as tools for committing or planning crime, and as a "symbol" of crime (intimidation or deception). One section of this article discusses how particular types of criminals, i.e., organized crime groups and white-collar offenders, are using ICT to commit their crimes. In discussing the challenges faced by legislators in countering ICT-related crime, this article presents a table that displays legal provisions designed to target computer-related crime in the 15 European Union Member States. Regarding law enforcement efforts against ICT-related crime, the discussion notes ways in which law enforcement is itself using new ICT's to detect, identify, and investigate criminal activities. The scientific community is also involved in the fight against ICT-related crime, as it discovers and develops ways to increase ICT security and tailor technologies for law enforcement tasks. 1 table and 29 references
