The attack was so damaging that in United Kingdom it had affected the National Health Services of the country and has stalled critical health care services like surgeries and emergency attention.
The countries that were hit included India.
That's why the government, when we came into government in 2010, put money into cyber security.
- How can people protect their computers?
Europol has been analysing the virus and is yet to identify the hacking group behind the massive attacks.
Australia's top cybersecurity adviser has warned "this is not game over" after more than 200 000 people across 150 countries were victims one of the biggest "ransomware" attacks in history.
Account addresses hardcoded into the WannaCry software code showed the attackers received $32,500 in anonymous bitcoin till Sunday, but that amount could rise as more victims rush to pay ransoms of $300 or more just one day before the deadline expires.
Authorities are also asking anyone affected by the virus to go to nomoreransom.org for more information about how to unlock your computer without paying the attackers.
"Yes, ransomware is a major problem in Australia, and this attack is no different... it doesn't discriminate and affects home and business users", he said.
'Our IT provider deploy state-of-the-art security systems to prevent and block attacks such as this.
The spokesman for Dorset CCG said: "We are pleased to confirm that the Ransomware attack has had little impact on the health community in Dorset, however we continue to be vigilant".
Although the hospital in Sterling Way, Edmonton wasn't hacked, the internet and internal email system was shut down on Friday and given a "robust overhaul" as a precaution to further attacks.
There is still no evidence any of our hospital systems were affected and we are completely confident no patient data was involved.
However, Wainwright said Europol was working on the basis that the cyber-attack was carried out by criminals rather than terrorists, but noted that "remarkably few" payments had been made so far.
British Prime Minister Theresa May denied reports that her government had neglected cyber-security issues.
Professor Clark said ransomware represented a growing threat to computer users but pointed out that this virus was not new and a "patch" had already been completed to protect newer operating systems but not "obsolete" ones like Windows XP.
