Abstract: Cybercrime is the result of the conjunction of three factors: motivation, opportunity and lack of guardianship. This article analyzes the motivation of computer criminals.There are two types of attacks against computers – from the point of view of the position of the cybercriminal – the outsiders and the insiders. For a long period, it was considered that, the inside attacks were the majority of crimes, but recent studies have shown a relatively balanced position between inside and outside attacks. The inside attack is more likely to be left unreported by the companies, who prefer to solve any “problem” inside, without the implication of police and justice authorities. This policy strongly relates with the image that a company has in the eyes of partners and clients, any major breach of security affecting this image. However, it looks like the companies prefer to adopt more drastic measures against exterior attacks, than to recognize and to take measures to prevent the inside attacks.
Keywords: cybercrime, computer criminals' motivation.
