As everyone knows by now WannaCry / WanaCrypt0r ransomware would encrypt your hardrive, lock you out and simply ask for payment between $300.00 to $600.00 to restore access back. There are certainly users out there that paid, but how many paid and how much did WannaCry / WanaCryptor. According to ActualRansom
The three bitcoin wallets tied to #WannaCry ransomware have received 296 payments totaling 48.86359565 BTC ($99,448.11 USD).
It is a very impressive amount of money for a few days of work.
