Etymology

Origin of cybercrime

First recorded in 1990–95; cyber- + crime

Explanation

Cybercrime is illegal activity that involves a computer network. Computer hacking and using the Internet to steal credit card numbers are both kinds of cybercrime. When criminals use a computer that's connected to the Internet to commit a crime, it's considered cybercrime. If you have your identity stolen after entering information on a website you think is secure, you're a victim of cybercrime. Malware or computer viruses are another type of cybercrime. The word itself uses the prefix cyber-, which since the early 1990s has been used in many words to signify a connection to the Internet or electronics.
