In the era of pervasive digital connectivity, the prevalence of cyber-crime, particularly online bullying and harassment, has emerged as a profound societal challenge. This abstract encapsulates a proposed chapter that seeks to unravel the intricate psychological impact of cyber-crime. With a focus on the dynamics of victimization, perpetration, and bystander experiences, the chapter aims to define cyber-crime through a psychological lens. Exploring the diverse profiles of targets and the correlational impact on mental health, the research delves into the motivations of cyber aggressors and the role of anonymity in fostering online harassment. Additionally, the bystander effect in the digital age is examined, probing the psychological consequences on those who witness but do not intervene. The chapter also addresses coping mechanisms employed by victims and resilience factors that may mitigate the psychological toll. Ethical considerations and legal frameworks surrounding cyber-crime are analysed, contributing to a comprehensive understanding of the issue.
