Meanwhile, HSE chief Tony O'Brien urged caution.

Meanwhile G7 finance ministers meeting in Italy vowed to unite against cyber crime, as it represented a growing threat to their economies and should be tackled as a priority.

But around a fifth of NHS trusts were hit in the attack, forcing them to postpone operations and procedures over the weekend and more could be revealed when people return to work this morning.

At the height of the attack Friday and early Saturday, 48 organizations in the NHS were affected, and hospitals in London, North West England and Central England urged people with non-emergency conditions to stay.

Wallace said the government used to contract for computer services across the entire NHS but that in 2007 that was stopped and left to the individual trusts.

"Since the global coordinated ransomware attack on thousands of private and public sector organisations across dozens of countries on Friday, there have been no sustained new attacks of that kind".

Wainwright said he was anxious that the ransomware attack might spread further once people return to work on Monday and log on to their computers.

'There have also been other reports made to our online cyber security network and the difficulty is of course there are literally hundres of instances of ransomware in Australia each week and so we are now seeking to confirm whether these are examples of the particular ransomware that has cause so much havoc for example in the United Kingdom'.

The virus exploits a vulnerability in Microsoft Windows software, first identified by the US National Security Agency, experts have said.
