The computer virus-extortionist Green Hat, similar to the malware WannaCry, appeared in China. It does not allow users to start the operating system, and when trying to do this, a window with the account number of the messenger QQ appears on the screen.
To obtain a password for unlocking files, users need to pay a certain amount. The creators of the virus did not resort to anonymity by publishing their account number QQ.
The large-scale cyberattack WannaCry has affected more than 200 thousand users in 150 countries. Hackers used the modified malicious program of the US National Security Agency.
