The most discussed subject in media in the past days was WannaCry – the biggest cyberattack the world has ever seen. The ransomware attack is triggered by a virus that locks people out of their computer files and demands that they pay a ransom in bitcoins to the hackers. All the important files on the computer are being crypted and can’t be restored or unlocked in any other way. The massive cyber-attack is using tools believed to have been stolen from the US National Security Agency (NSA).
