WannaCry is a deadly piece of
ransomware that started spreading like
wildfire threw the internet on 12th May, 2017. The virus works by encrypting a user's personal files and demanding that a $300
ransom be payed in bitcoin in order for the user to get back their files. If no payment is made within 3 days, the ransom rises to $600. If the user doesn't pay the $600 within 7 days, all their personal files will be lost.
A typical message you might get if you're infected with WannaCry is: "
Oops, all your
files have been
encrypted!"
