  Abstract

The entire nation is suffering tremendous pain even as of 2021 due to the infection of COVID-19 pandemic that started in 2019. Even in this era of the Corona 19 epidemic, voice phishing criminals continue to deceive and extort money by evolving fraud methods despite the nation"s desperate efforts to prevent it. In particular, reflecting the situation of the Corona-19 pandemic era, voice phishing crimes are summarized as crimes of fraudulent loans impersonating the financial sector and impersonating prosecutors for people who are experiencing financial difficulties. From this point of view, in this paper, 10 voice phishing criminals pretending to be prosecutors and 10 voice phishing sound sources of bank loan fraud criminals are divided into two groups to find out what the criminal’s voice characteristics were. Experiments were conducted on sound sources released by related institutions such as the Financial Supervisory Service. As a result of the experiment, voice phishing criminals pretending to be prosecutors used a method that made them feel intimidation in their kindness. On the other hand, we were able to identify the fact that voice phishing criminals in the case of financial institution loan scams used fraudulent methods such as showing kindness and providing assistance to those in financial difficulties by the country and banks.
