The cost of last year's cyberattack on the Health Service Executive has reached €70m.

The HSE was targeted by a major ransomware attack in May 2021 that caused widespread disruption and saw information held on HSE computer systems illegally accessed and copied.

The HSE has previously said that the costs could rise to €100m.

According to the latest report of the State's spending watchdog, the Comptroller and Auditor General, the HSE will need to spend almost €657 million over seven years to implement cyber security improvements.

As of august this year, the costs associated with the cyberattack had reached €70,471,131.

The figures were contained in a reply to a parliamentary question from Aontú Leader Peadar Tóibín.

"Within two years, the cyber security attack has cost the citizen over €70million," Mr Tóibín said.

"This does not take into consideration the human cost, in terms of the cancelled diagnosis and treatment of patients, many of whom had life threatening illnesses."

Mr Tóibín said that despite the fact that the investigation into the attack found weaknesses in the HSE's cybersecurity, no one has been held to account.

"Without accountability there will be no change," he said.
