WannaCry is a malware and extortionist program that attacks only computers using the Microsoft operating system. The program encrypts all the files of the user and then demands a ransom for their decryption. The WannaCry virus became popular in 2017, as it had attacked computers in Spain and then spread to other countries. Currently, Russia, Ukraine and India are the leading victims of WannaCry attacks. After finishing the process of encryption, there is a demand on the screen of the hacked computer to transfer a certain amount of money in Bitcoin and usually this is equivalent to about $300. According to linguistic analysis, WannaCry hackers are believed to be from China, however, some experts think that this is just a trick and the original WannaCry ransomware is from Korea.
