“Fraud was suspected in 73 cases out of one million bankcard payment transactions last year,” Tállai said in a statement on Sunday.

He said that the number of online payments connected with fraud has exploded around the world in recent years, with the chief aim of obtaining personal financial data.

The method commonly used involves phone calls or e-mail messages by fraudsters posing as bank staff.

Tállai noted that phishing for personal data under the guise of tax and customs office NAV interventions was widespread in 2019.

More recently, however, the preferred method is to send fraudulent SMS messages related to postal packages containing malicious links.

The Hungarian Banking Association has set up a working group with experts of the national cybercrime institute, police force and the national office of investigations, as well as the banking sector, which has played a significant role in exposing the fraud cases, Tállai said.
