It relates to the online game, Fortnite, which is very popular with children.
Fraudsters have started a scam offering players free V-Bucks, the currency used as part of the game.
The garda warning stated: "They will seek access to your account and create charges. They may also ask for your phone number and sign you up to premium rate subscription.
“We ask people to be careful with their personal data in all cases."
