Ms Sturgeon said she was not aware of any ransoms being paid over the cyber attack but said that will be part of the police investigation.
Europol said on Monday it was continuing to hunt for the culprits behind the unprecedented attack. However, a later report has suggested that the count has gone up to 2 lakh systems in 150 countries, including India.
Security agencies are hunting for those behind a crippling cyber attack which has so far hit hundreds of thousands of computers worldwide, including at government agencies, factories and health services.
NHS organisations across the country are on alert for a possible recurrence of Friday's cyberattack as staff return to work. In the United Kingdom, hospitals and medical practices were infected resulting in the cancellation of medical appointments.
Although there is no evidence that patient data was compromised, British Home Secretary Amber Rudd told the BBC that NHS must learn from the attack and upgrade its IT systems.
The attack was one of the largest ransomware attacks in history.
NZ cyber security officials say they'll be staying vigilant with the working week starting tomorrow.
Dr Anne Rainsberry, NHS incident director, said: "We have been working with 47 organisations providing urgent and emergency care who have been infected to varying degrees". Other targets include some Asian university networks, the German transportation system, and the Spanish telecom company Telefonica.
The anonymous specialist, known only as MalwareTech, issued a warning that hackers could upgrade the virus to remove the kill switch.
The UK government has defended the NHS's cyber-security procedures, days after a number of trusts were taken offline by the WannaCry ransomware.
The ransomware locks users' files and demands a Dollars 300 payment to allow access.
The Microsoft President also added: "The governments of the world should treat this attack as a wake-up call". A worrying addition is that if one pc in a network is infected, the virus spreads to all computers on that network. Hackers made use of a vulnerability that existed in Microsoft Windows.
"No NHS Tayside systems or hospital sites were affected by the cyber attack and there was no impact on NHS Tayside's Emergency Departments, outpatient clinics or Out-of-Hours Service".
The virus is primarily hitting older versions of Windows since Microsoft had already released a security patch for Windows 10.
