Computers in 18 police units in Chittoor, Krishna, Guntur, Visakhatpatnam and Srikakulam districts were affected. This particular strain, WannaCry, exploits a vulnerability in Windows that many systems have not yet patched. But computers and networks that hadn't updated their systems were still at risk.
Ms Robison said: "This has been a global cyber-attack which has impacted on countries across the world and clearly any incident of this nature is hugely concerning - but it's important to stress that there is no evidence to suggest patient data has been compromised".
"Later we found out that the domain was supposed to be unregistered and the malware was counting on this, thus by registering it we inadvertently stopped any subsequent infections", @MalwareTechBlog told CNNTech.
Monday was expected to be a busy day, especially in Asia which may not have seen the worst of the impact yet, as companies and organizations turned on their computers.
The Russian Interior Ministry said some of its computers had been hit by a "virus attack".
And a security researcher warned there might be another attack imminently. Fedex said Friday it was "experiencing interference with some of our Windows-based systems caused by malware". There's no reason for them to stop. The malware encrypts the files.
After the IT system hack crept across England on Friday, the health service declared a major incident and medics were forced to cancel routine operations and divert ambulances.
"This is big and set to get bigger".
Hospitals, companies, universities and governments across almost 100 countries were hounded by a cyberattack that locked computers and demanded ransom.
Forcepoint originally said in a statement that the attack had "global scope", affecting organisations in Australia, Belgium, France, Germany, Italy and Mexico.
He also questioned why the government had not extended a £5.5m annual contract with Microsoft in 2015 to continue to provide support for the redundant XP operating system, still in use in parts of some NHS trusts.
Then, there were users who failed to quickly update their software after Microsoft released a fix in March.
And all this may be just a taste of what's coming, another cyber security expert warned.
British cybersecurity expert Graham Cluley doesn't want to blame the NSA for the attack.
The ransomware, called WannaCrypt or WannaCry, locks down all the files on an infected computer and asks the computer's administrator to pay to regain control of them.
A further 13 NHS Health Boards in Scotland were also targeted in the attack.
Hacking group or groups were yet to claim responsibility for the attack.
The anonymous specialist, known only as MalwareTech, is said to have prevented more than 100,000 computers across the globe from being infected.
The U.S. government on Saturday issued a technical alert with advice on how to protect against the attacks, asking victims to report any to the Federal Bureau of Investigation or Department of Homeland Security.
World Capitals - Tens of thousands of computers in nearly 150 countries were infected with ransomware demanding ransom payments during an worldwide cyberattack, which some experts believe was inspired by a National Security Agency (NSA) tool kit that was leaked a year ago.
