Contemporary reality shows that a considerable part of offenders make use of modern technologies, are in step with the latest changes in modern tech, which hinders greatly the preventing activities, revealing and fight against offenses. The starting point of the research are legislative intervention proposals on the introduction of two tools, subsequently acquiring certain technologies and softs, and strengthening the cooperation between law enforcement agencies and private sector, to help prosecuting authorities and investigation agencies. These methods take the form of dual nature, of mixed functions methods, and could contribute decisively to prevention and effectively counter certain categories of offenses; strengthen the evidence in criminal proceedings; determine some categories of subjects to abandon (quit) criminal activities initiated and/or already in progress; identifying suspects and others. Thus, the two proposed methods could improve the activity of law enforcement agencies and are useful to us for varying situations such as when, while the suspect is identified, the evidence is insufficient; or there is no certainty that the perpetrator really pursues the satisfaction of the alleged criminal intent; prevent the occurrence of harmful consequences; cases in which the criminal intent is not fully satisfied, as well as other assumptions. The conceptual forms of these methods are: controlled disconnection of certain electronic communications services; obstruction, jamming or controlled interference of electronic communications services. The theoretical and scientific support of the paper is comprehensive, applying the logical, the comparative and the systemic methods of research.
