An investigation is underway following a data breach at Dublin Airport.
The DAA says it's aware of a "data security incident" involving third-party supplier, Collins Aerospace.
It says there's currently no evidence of any direct impact on its systems - and passengers who travelled in August do not need to take any immediate action.
They should, however, remain alert to any unusual activity related to their bookings.
Collins Aerospace was the subject of a cyber attack last month, affecting a number of major airports across Europe.
