Tusla continues to be "significantly affected" by the recent cyber attack on HSE systems.

In an update issued this evening, the Child and Family Agency said while there was no indication of information theft on its operating systems, there was evidence of encryption associated with the HSE attack.

Its CEO updated the Oireachtas Committee on Children, Disability, Equality and Integration on the situation in writing.

Bernard Gloster noted that many of Tusla's files and databases on the HSE network "are unavailable at this time".

He said referrals continued to operate manually as the portal normally used for identifying concerns to the agency was switched off.

"We are working with our legal representatives and the Courts Service to ensure that no child subject of court proceedings is negatively impacted," he said.

Mr Gloster also said that the agency continued to ensure that "important payments due to be made" were "fulfilled to the nearest possible normal timelines".

Aftercare allowances to care leavers, foster care payments, payments to providers and staff were among the examples cited.

He said provisions were also made for cases before the court, which he noted as "often time sensitive".

Mr Gloster said further updates would be issued "in due course".
