Cyber crime (а.к.а. computer crime, computer-related crime or high-tech crime) could be understood as “criminal acts committed using electronic communications networks and information systems or against such networks and systems. In fact the term “cyber crime” is applied to three categories of criminal activities. The first covers traditional forms of crime such as fraud or forgery, though in a cyber crime context relates specifically to crimes committed over electronic communication networks and information systems (electronic networks). The second concerns the publication of illegal content over electronic media (i.e. child sexual abuse material or incitement to racial hatred). The third includes crimes unique to electronic networks, i.e. attacks against information systems, denial of service and hacking.

In the last few years there has been a significant impetus in developing cyber crime regulations in Bulgaria. One of the senior experts of Law and Internet Foundation has participated as a key expert in the work group, which drafted the secondary legislation of the cyber crime section of the Criminal Code. Nowadays he continues to consult the Ministry of Interior and the Bulgarian prosecutor's office in investigating cybercrime cases.

In 2007 a group of experts from the Law and Internet Foundation prepared an analysis, called ”Intellectual property rights and cybercrime: overcoming the gap between law and information technologies” as part of a project with the same name. Later the Foundation’s team has elaborated its researches in the field upon two consecutive projects – Advanced research workshop ”Cyber Terrorism as a New Security Threat” (financed by NATO’s Science for Peace and Security Programme) and “Justice in the Digital Era - Strengthening Capacity of Magistrates in Bulgaria and Romania to Investigate, Prosecute and Produce Judgments in Cases Involving Cyber crime” - a project, realized with the financial support of the European Commission. The second project finished in 2009 included 4 significant events addressed to magistrates in connection with the peculiarities of computer-related crimes, analyses of the current status in prevention and fight against computer crimes in Bulgaria and Romania and drafting recommendations for legislation improvements in the ICT Law area.

In 2009 Law and Internet Foundation sub-served the implementation of six cybercrime trainings and four training seminars for trainers of 150 judges, public prosecutors and investigators from all over the country. The main events’ topics were technical and legal aspects of cyber crime per se and computer-related crime, infringement of intellectual property rights in Internet, money laundering, etc.
