It is concluded that the negative consequences of the reforms carried out in Russia partly themselves pose a threat to its national security. The article studies the formation of the state criminal law policy; the development of criminal law measures against terrorism, extremism, economic crime and corruption; countering the malicious use of artificial intelligence and robotics as priority areas of countering threats to national security by criminal legal means. The formation of an effective criminal legal framework for countering economic crime and corruption is associated with the development of the modern criminal and criminal-legal policy concept. The changes in Russian legislation aimed at ensuring national security through the tightening a number of the Criminal Code norms in relation to terrorist and extremist crimes after the coup d’état in Ukraine in 2014 are illustrative. The risks of malicious use of artificial intelligence require a proactive reaction of the domestic legislator. Analyzing the sphere of development of the economic foundations of the state and society, it is necessary to focus on the conditions of fierce competition from foreign goods, works and services. At the same time, it is impossible not to take into account the fact that competition is often associated not only with scientific and technological advantages, but also with various kinds of abuses on the part of legal entities, which brings the authors back to the discussion on the introduction of the institution of legal entities criminal liability in the Russian Federation.
