After infecting over two lakh computers and crippling life in 150 countries, the global ransomware attack continued for the third day on Monday, with more reports of hacking pouring in from India, China and Japan as offices re-opened after a tumultuous weekend.
The letter further read that the security experts would be available for May 16 and 17, 2017.
Car-maker Nissan's Chennai plants were also affected by the ransomware attack but normal operations were soon restored. "More than technical guidance, I want you to make sure you are spending the time needed to understand the concerns they have and that they know we are here to help". Also, over 60% of the 225,000 ATMs in the country run on the "outdated" Windows XP. And this is why India is vulnerable to the attacks. But some organisations didn't apply it, and others were running older versions of Windows that Microsoft no longer supports.
If you're facing a ransom demand and locked out of your files, law enforcement and cybersecurity experts discourage paying ransoms because it gives incentives to hackers and pays for their future attacks.
Despite the high profile of WannaCry, widespread malware outbreaks have become less common over the years, as Microsoft has improved the security of its systems, said Ziv Mador, vice president for security research at Trustwave, a security services firm.
Mr Hutchins, from Devon, has been credited with stopping the WannaCry attack from spreading across the globe by accidentally triggering a "kill switch".

Gibbs played 90 minutes in Arsenal's 2-0 victory over Manchester United on the weekend which keeps their top four hopes alive. He added: "I said a few weeks ago that we have to win every game and we didn't do that against Tottenham".
He added that the Cyber Swachhta Kendra - government's portal on information about cyber security - is being updated on regular basis since Saturday.
The ransomware takes over users' files, demanding $300 (£230) to restore them.
"For Microsoft to say that governments should stop developing exploits to Microsoft products is naive", said Mr Brian Lord, a managing director at PGI Cyber and former deputy director at the Government Communications Headquarters, one of the UK's intelligence agencies. An official cyber coordination centre is expected to launch operations by June which will take precautions against such attacks.
However, in response, Microsoft states it has developed and released a special update for Windows XP although this particular version is no longer serviced by the tech giant. Now, the Navy is shifting towards the use of Windows 10.
CERT-In further said that it sent out advisory to the Reserve Bank of India on the matter, on Saturday itself. It said there have been over 700 distress calls by customers in the last few days, following the discovery of the attacks which has impacted 150 countries globally.
Computer giant Microsoft said the attack, which has affected hundreds of thousands of computers, should serve as a wake-up call.
