This paper examines the application of artificial intelligence technologies to combat economic crimes, including those committed using information and telecommunications technologies. Specific measures for combating economic crimes are considered, including the creation of a dedicated digital platform for information exchange between law enforcement agencies, the Central Bank, credit organizations and telecommunications operators, monitoring and restricting access to illegal resources, and the development of partnerships between security institutions. Domestic information-analytical systems using artificial intelligence are analyzed: AIAS of the Ministry of Internal Affairs of Russia “SORM”, the Sber Analytics (Sber AI) platform, the VIS (Visual Investigation System), the FindFace Security system, the “Graph” information-analytical system, the FinCERT platform of the Bank of Russia, and the Financial Monitoring information-analytical system of Rosfinmonitoring. It is determined that combating economic crimes committed using information and telecommunications technologies should be comprehensive, incorporating various capabilities of modern information and telecommunications technologies — from the creation of dedicated digital platforms and monitoring and blocking of illegal resources or content, to the use of artificial intelligence systems and analytical systems. A conclusion is drawn about the need for further improvement of the mechanisms of functioning of artificial intelligence technologies, training and retraining of law enforcement personnel, and integration of domestic information-analytical systems with AI between various departments of the Ministry of Internal Affairs of Russia.
