Who's being targeted for blame? In a surprise move over the weekend, Microsoft released a patch for versions of Windows it no longer supports - because many businesses and organizations use legacy technology as critical infrastructure.

Then there's the USA government, whose Windows hacking tools were leaked to the internet and got into the hands of cybercriminals. It then plays a message demanding that a ransom be paid to fix it.

While speaking to media, Subhamangala, Cyber Security expert said that so far there are so many states which has been affected with this malware.

Here are some of the key players in the attack and what may - or may not - be their fault. Cert-In has asked computer users to deploy anti-virus software, block spam and refrain from opening attachments or links in unsolicited emails.

On top of that, the NSA would likely be able to claim that it is shielded from liability under the doctrine of sovereign immunity, which says that the government can not be sued over carrying out its official duties. "The intelligence community should develop strong procedures that when such tools leak, they immediately give relevant information to software developers and security vendors so protections can be developed before attacks are seen in the wild". Wannacry encrypts the files on infected Windows system and spreads by exploiting vulnerabilities, it said. He added it was a helpful thing that the company had set up a patch capable of stopping the attack.

It comes amid concerns networks were left vulnerable because they were still using outdated Windows XP software. He noted, however, the complexity that can be involved in patching a security hole.

Ms Rudd said the National Crime Agency (NCA) and the National Cyber Security Centre (NCSC) were now part of an "international manhunt" to find the perpetrators.

Computer users across the world are powering on the next wave of a global cyber attack. Multiple backups also help.

However, if you do pay, you're only fueling the fire.

"It's not rocket science", Litan said.

NHS England said that, as of 3pm on Monday, two hospitals remained on divert following the attack, down from seven on Sunday.

Sean Pike, program VP in the security products group at IDC, a tech industry research provider, pointed that everyone has been a bit numb to attacks because it is something they hear so much about now and Microsoft benefits from that.
