The emergence of the digital economy and the era of big data raise the important issue of personal information protection, which is the basis of cyberspace security and an important part of national security of the state. Based on the analysis of legislative acts and statistical data of the Bank of Russia, the article characterises the dynamics of unauthorised transactions in commercial banks. The reasons influencing the potential possibility of their commission and the measures of the Government of the Russian Federation and the Bank of Russia taken to counteract them are named. As a result of the study, it was revealed that in modern conditions, most of the unauthorised transactions are CNP-transactions, the commission of which becomes possible when fraudsters know telephone numbers and use fraudulent phone calls. As a solution to the problem of illegal dissemination of personal data, the authors proposed several ways related to minimising the impact of social engineering.
