A cybercriminal is a person who attempts an illegal attack on a particular computer system or who commits a conventional offence or crime using a computer tool or system.
Over the past decade, we have witnessed a shift in the world of cybercrime. In the 1980s and 1990s this was still an amateur activity on the part of computer enthusiasts eager for recognition. Malware was apparent, it displayed animations on the screen or destroyed data on infected computers.
With the Internet proliferation of more and more economic activities, such as e-commerce or e-banking, the challenges have changed and more and more criminals have become interested in technology. Over the past decade, we have seen increasingly stealthy malware seeking to control computers for as long as possible.

From the smallest Nigerian scammer to the godfather who runs an entire organisation, the market has enough capacity for everyone and some reports today claim that cybercrime is one of the most lucrative criminal activities.

Along with these are script-kiddies, usually beginners in the field, who use the tools of others, as well as many actors with little or no computer skills. The latter for the most part engage in scams, hoaxes or other spam of all kinds. Finally, the parallel cybercrime economy is swarming with recruiters and other criminal accessories.
