FIFA also reminded that its official website was the only legitimate website where supporters could buy tickets for the World Cup matches.
"Tickets purchased via unauthorized distribution channels, including all tickets purchased through Viagogo AG, will be canceled once identified," FIFA added.
Russia will host its first-ever FIFA World Cup from June 14 to July 15. The matches are set to take place at 12 arenas in 11 cities across the country.
