Cyber-crime (computer and Internet related crime) is a relatively new form of crime and is one of the fastest growing criminal activities in the world. This work aims to discover whether cybercrime conforms to a power law relationship and to offer a novel perspective on this topic. A power law relationship occurs when the probability of measuring a particular value of some quantity varies inversely as a power of that value, and can be visualised as a straight line on a log-log plot. Analysis carried out on the historical CSI/FBI data sets shows that a single power law relationship does not exist. However, evidence is provided to demonstrate the existence of two power law relationships. When comparing this result to other fields, one relationship is found to be similar to the power law trend found in conventional warfare while the other is close to that of terrorism in non-G7 countries. These findings are interpreted by taking into account aspects of cybercrime trends, human motivation and models for warfare and terrorism in the literature.
