Nearly all mainstream media wrote today about massive ransomware attacks around the world: 16 medical institutions in UK, strong rumours that huge companies in Russia, and even Russian Ministry of Internal Affairs suffered a damage.

As I see some security bulletin says that there is a critical vulnerability in it”. That’s it.
