The damage of a targeted impact on financial organizations due to the activation of hacker groups is analyzed. These attacks were mainly directed at the processing of bank cards, ATMs and at the SWIFT system, which is an international system for transmitting financial information and payments. Currently, special attention is paid to the attacks of hacker groups that receive funding from governments and criminal groups to influence the world's leading banks. Based on the assessment of the impact of computer attacks, it was concluded that the banking sector is a vulnerable sector of the economy before computer attacks on information systems that can damage not only small, but also large backbone credit institutions that own more than 60% of the total assets of the banking sector.
