The purpose of the work is to identify factors influencing changes in the criminological portrait of a juvenile offender, features of its changes, as well as modern trends shaping the personality of a juvenile offender. The study gives reason to say that risk factors for involvement in criminal activity as a separate type of criminogenic factors have not undergone radical changes. The work gives reason to assume that with the development of ICT and communication at a distance, influence of the peer group and the role of hierarchy in the juvenile delinquency may be weakened. In addition, there still exist a problem associated with the lack of terminology, methods for assessing the personality of a juvenile cybercriminal, as well as the very definition of the juvenile cybercriminal concept. The results of the study can be used to develop strategies and measures to prevent and combat juvenile delinquency.
