Given that computer hacking causes huge losses among firms, it is necessary to understand how individuals engage in committing it. Previous research done under different task environments has suggested a variety of factors affecting individual intention for hacking. This study developed an integrated model with four dimensions: motivation, morality, deterrence, and social learning. A survey was conducted to investigate the significant factors affecting individual’s intention for hacking. The results demonstrated that intrinsic motivation, extrinsic motivation, moral intensity, punishment certainty, punishment severity, and social influence were key factors that influence intentionality in computer hacking. In addition, we found a key factor ignored in the past, the severity level of computer hacking, which was a strongly significant moderator of all factors contributing to intentionality. Lastly, implications for information security management and direction so as to reduce computer hacking rate for practices are discussed.
