In my work I have been encountering ransomeware at client computers for some years now (fake police type mostly). The news about cryptoransomeware has been flooding around longer but last year was it popped up on my watch. This year it popped up more. Most got away ok with backups/cloud sync or it started encrypting files that were not that important. Only one has payed and reversed the encryption (before consulting me). This is not yet a flood but I suspect it will get worse and someone without backups will be encrypted and the price will be too high or the unencryption key will not be delivered.
