Soaring ticket prices and transport costs at this year's World Cup will expose fans to cyber fraud and scams as supporters are attracted by fakes in the mistaken belief they have bagged a bargain, an industry expert has warned, Reuters reported. 

Scam artists are active around every major global sporting event but there is an increased danger with World Cup tickets more expensive than at any previous edition, Nuno Sebastiao, the CEO and co-founder of Feedzai, told Reuters.    

"Large gatherings like a World Cup are a scammer's dream," said Sebastiao, whose company works with banks around the world to detect and prevent fraud and other financial crime.
