I First attacks and mode of action


1. The first attacks took place on May 12th.

2. Originally it was believed that the virus was spreading through email attachments.

3. WannaCry is classified as ransomware. A Ransomware is a malicious program that infiltrates a device (computer, server, smartphone) and encrypts all files in storage, virtually blocking users from accessing them. But the program does not stop here: after encrypting the files, it displays a message telling the victim that if he wants to use his device again, he has to pay in order to recover the files.WannaCry: what you should know
