There's been no evidence so far that patient data taken in a cyber attack on the HSE has appeared online, after the deadline for ransom expired last night.
Gardai have received a number of reports about potential breaches, however there's no conclusive proof they're linked to the HSE attack.
The ransomware breach's set to be raised at an Oireachtas committee later, with cyber experts set to address members.
Sinn Fein communications spokesperson, Ruairi O'Murchu, says the attack has raised some serious questions.
"There's a general narrative out there that we didn't have a sufficient amount of work done in terms of cyber security.
"There are questions as regards the National Cyber Security Centre - is it sufficiently manned and resourced? Does it have the skillsets required?"
