WannaCry virus primarily targeted Windows 7 computers

Insurers remain on alert as security experts warn of a second wave of cyber-attacks following the ransomware assault that hit tens of thousands of computers worldwide over the weekend. However, if your devices have been infected by WannaCry - the malware that has affected the NHS' computer system - the ransomware will lock your entire PC.

The recent global ransomware attack has once again proved that healthcare sector remains to be the most vulnerable to cybercrimes.

Dame Fiona and the Care Quality Commission wrote to the Health Secretary to highlight a "lack of understanding of security issues", according to the newspaper, and that "the external cyber threat is becoming a bigger consideration".

The BBC quoted analysts as saying organizations and businesses in Britain had paid some 38,000 dollars to cyber criminals for the decryption of files since Friday.

Wainwright said he was concerned that the numbers of those affected would continue to rise when people returned to work on Monday morning.

The statement said: "We can confirm that the radiology services affected by the national cyber-attack at Basingstoke and North Hampshire Hospital have been restored".

At a hospital in Norfolk, eastern England, staff were told on Monday they could still only view x-rays in one room, while pharmacy services were being restricted as computer systems were upgraded.

Once clicked, it takes encrypts users' hard drivers, blocking them from accessing it and any files it contains.

Also hit were Deutsche Bahn, the Russian Central Bank, Russian Railways, Russia's Interior Ministry, Megafon and Telefónica.

A spokesman said: "Our understanding is that if that had been acted on it would have prevented [the malware attack]". And giving the hackers what they want proves the worm is effective, the agency said.

The ransomware appeared to exploit a vulnerability in Microsoft Windows that was purportedly identified by the U.S. National Security Agency for its own purposes and was later leaked to the internet.

Russian Federation and Britain were among the worst-hit countries by the attack.

However, Wainwright said so far "remarkably few" payments had been made by the victims of the attack.

"If it is routine we are saying please leave it a day or two - if you are urgent we will prioritise but if not please give us a couple of days", she said.
