One of the adverse consequences of globalisation is the spread of illegal conduct in the world and an increase in crime rates. This circumstance determines the relevance of the subject under study. It is argued that the causes of illegal conduct are determined by the contradictions of social development, ideological confrontation, economic, political, social inequality of the world’s countries and the deformation of legal consciousness. The globalisation of the shadow economy, the emergence of new tax evasion schemes, including through offshore companies, laundering of proceeds from crime, piracy, raider seizures of other people’s property, arms trafficking, aggressive globalism in the foreign policy of a number of states, regional wars, domestic conflicts, information wars, arbitrary interpretation of certain religions, distortion of their principles by extremist organisations – all this causes the crisis state of the economy, politics, socio-cultural and spiritual spheres of society and crime in many countries of the globalised world. The purpose of this study is to highlight the understanding of illegal conduct through the lens of the adverse impact of globalisation processes on it. The methodological framework of this study comprises a system of philosophical and ideological, general scientific and special scientific principles and methods, namely principles of objectivity, concreteness, complexity; Aristotelian, systemic, structural-functional, formal legal, and comparison methods. The study found that illegal conduct in a globalised world is promoted by social contradictions generated by globalisation or stimulated by this process. It is noted that globalisation is contradictory. It has both positive and negative, anti-criminogenic and criminogenic properties, and criminogenics dominate – it is a peculiar consequence of both political, economic, and cultural expansion, and a significant stratification among the extraordinarily rich and poor not only at the national level, but also at the international level. Deformation of legal consciousness, extreme individualism, illegal conduct, crime, corruption affects the standard of living of society, contributes to the violation of human rights and forces us to independently search for numerous ways to realise legitimate interests, including illegal ones. The limitation of certain managerial capabilities of the state, which is necessarily the case in a globalised society, also has a negative impact on solving problems of human rights protection and crime prevention. It is proved that in general, globalisation contributes to inequality, injustice, the destruction of traditional values of society, people’s uncertainty about the future, the growing threat of illegitimate use of armed forces and aggression in the face of growing competition and imperial aspirations of individual governments. The scientific novelty of the article is an attempt to find all the globalisation factors that affect the deformation of legal conduct and stimulate the growth of crime rates. The results of the study contribute to finding ways to influence persons prone to illegal conduct, improving the means and methods of combating criminal organisations and individual criminals. This is the practical significance of the article
