Answer 1

`Hey,

Note: Brother if you have any queries related the answer please do comment. I would be very happy to resolve all your queries.

Ransomware is a malware that stealthily gets installed in our PC or mobile device and holds our files or operating system functions for ransom. It restricts the user from using their device and from accessing their files and demands that the victim has to pay some ransom within three days and if the user fails to do so then WannaCry will delete all of the encrypted files and all data will be lost.

WannaCry works by encrypting data on a computer that has been infected and then tells the user that their files have been locked and displays information on how much is to be paid and when payment is taken through Bitcoin(a payment medium).

WannaCry is a type of ransomware that infected the National Health Service(NHS) and other organisations across the globe including government institutions in China, Russia, the US and most of Europe. India was among the countries worst affected by the WannaCry attack. NHS England was also the victim of a massive ransomware attack resulting in some patients’ operations being cancelled.

The attack occurred after the USA’s National Security Agency discovered a vulnerability in Microsoft’s software called EternalBlue. This exploit was leaked by a hacker group called the Shadow Brokers earlier this year but the vulnerability was patched by Microsoft as soon as it happened.The problem comes from older versions of Windows or those without Windows Updates, as these were not patched by Microsoft and were left open to attacks. Russia and India were hit particularly hard because Microsoft’s Windows XP-one of the operating systems most at risk- was still widely used in these countries.

Kindly revert for any queries
