This paper looks at the research results of research into the risky behaviour of Slovak children on the Internet, implemented in late 2013 and 2014 by a research team at the Centre for the Prevention of Risky Virtual Communication, Palacký University in Olomouc. In this article we focus on a key part of the research-cyberbullying from the perspective of victims and attackers. The paper describes the most common forms of attacks Slovak children are exposed to and also focuses on role-switching from victim to attacker which occurs fairly frequently among the Slovak population. The article also looks at the most common Internet services and communication platforms which are exploited in attacks.
