The pay and benefits details of nearly 2,000 staff members of daa, which operates Dublin Airport, were compromised due to a recent cyber attack on a third party application used by professional service provider Aon, the Sunday Times reported.
A spokesperson said that as a result of a recent cyber attack on a third party application, data relating to some employees' pay and benefits was compromised.
The daa was one of many global companies affected last month by the attack on the file-transfer software tool MOVEit, used by Aon.
It said it has notified the Data Protection Commissioner and was offering support to affected employees.
In a statement it added: "daa can confirm that as a result of a recent cyber-attack on Aon, a third-party professional service provider, data relating to some employees' pay and benefits was compromised.
"daa takes the security of sensitive personal information extremely seriously and has notified the Data Protection Commission of the third-party breach.
"daa is offering support, advice and assistance to employees impacted by this criminal cyber-attack."
Aon is contracted by daa to compile and print rewards statements to some of its employees.
Other victims of the cyber attack include US government agencies, the UK's telecom regulator, and energy major Shell, all of whom have been hit by a security flaw in Progress Software's MOVEit product discovered in May.
