Organized crime represents a serious threat to the security, economy, and
sometimes for the legal order of the country. Criminal groups not only use
the achievements of information and communication technologies (iCT) for the
expansion of the organization, communication and management of activities
and resources, but also invest, through secret and illegal channels, to
develop their own applications of their own applications that they will use
for their activities. Organized criminal groups themselves, the most
powerful ones, have their iCT experts whose goal is not only to protect
communication channels, but also to devise new ways of ?circumventing? and
neutralizing police measures and techniques for detecting and monitoring
their activities. Members of organized criminal groups to use those
communication applications that enable encrypted transmission to electronic
devices using the necessary operating system, enabling the installation of
the application and the establishment of a connection to the internet in
order to enable the necessary protected communication. There are also
applications that allow the entire device to be encrypted, making it
difficult to find its contents or discover the necessary information and
evidence. This paper presents the characteristics of organized crime and
their operating modes, with an emphasis on the use of cryptographic
techniques. Case studies are illustrating the size and scope of abuse of
encryption by organized criminal groups, by data on cases which were
processed, as well as challenges in opposing the abuse of cryptography from
a technical-technological and legal aspect, after that we provided guideline
for improving the mechanisms for reduction of organized crime.

From the viewpoint of cybercrime, young people represent a particularly vulnerable category of Internet users: children, adolescents and students. Young people are, undoubtedly, the most common and the most gullible users of social networks. Due to lack of education related to dangers they are exposed to on social networks, inexperienced users recklessly post information and multimedia contents on their profiles which can be misused by differently motivated Internet users. Apart from being exposed to the risk from the violation of personal privacy and misuse of personal data, young people are exposed to the risk from political or ideological manipulation. Various studies on social networks and secondary school students have been conducted in the Republic of Serbia. However, no study in this field which would look at university students has yet been conducted. The purpose of this study was to discover the extent to which students use social networking sites, but also the sources and ways students perceive online security risks associated with social networking. Study results show that the media has a dominant role in educating young people on the risks associated with social networking and that the impact of the media is greater than the impact of other educational factors such as family, school or university. ; S gledišta kibernetičkoga kriminaliteta mladi ljudi (djeca, adolescenti i studenti) predstavljaju osobito ranjivu skupinu korisnika interneta. Mladi su ljudi, bez sumnje, najčešći i najlakovjerniji korisnici društvenih mreža. Zbog nedostatka edukacije o opasnostima kojima su izloženi na društvenim mrežama, neiskusni korisnici na svojim profilima nesmotreno objavljuju informacije i multimedijske sadržaje koje mogu upotrijebiti korisnici interneta koji imaju drugačije motive. Osim što su izloženi riziku kršenja osobne privatnosti i zlouporabe osobnih podataka, mladi se ljudi izlažu mogućoj političkoj i ideološkoj manipulaciji. U Republici Srbiji provedene su razne studije o društvenim mrežama i srednjoškolcima, no ni jedna od tih studija nije za ciljnu skupinu imala studente. Svrha ovoga istraživanja bila je ustanoviti do koje se mjere studenti koriste društvenim mrežama na internetu i utvrditi izvore putem kojih se informiraju o sigurnosnim rizicima vezanim uz društveno umrežavanje. Rezultati istraživanja pokazuju da mediji imaju dominantnu ulogu u upoznavanju mladih ljudi s rizicima vezanim uz društveno umrežavanje. Utjecaj medija veći je od utjecaja ostalih odgojno-obrazovnih čimbenika kao što su obitelj, škola ili fakultet.

"Individuals exist in both the real and the virtual worlds, and it is not always clear which sphere is more important to them. Cyberspace provides many opportunities, challenges, and risks. Virtual worlds create chances for many people to revive and carry out dangerous or malicious intentions, frustrations, or vices. While vices like gambling impact the individual seeking a risk, many are unwillingly subjected to these dangerous behaviors, including bullying, stalking, human trafficking, and more, which circulate between real and virtual worlds and present a danger for anyone in cyberspace, social networks, and virtual groups.Analyzing New Forms of Social Disorders in Modern Virtual Environments provides expert articles from the areas of psychology, sociology, technology, and security on the phenomena and interplay of virtual lives, real behavior, and subsequent peril and also provides major challenges and safety measures. Covering topics such as cyber bullying, virtual violence, and virtual terror, this book is ideal for school instructors, administrators, psychology practitioners, scientists, and police."--
