There are no hattricks scored yet at this World Cup. If none happen in the last 4 games, this will be the first World Cup ever to record something like that.

If the tournament runs to its conclusion without a three-goal haul it will be the first time that this has happened in a FIFA World Cup. There were no less than seven hat-tricks at Switzerland 1954 and five at France 1938. Four came at Mexico 1986 and also at Spain 1982.
