After WannaCry, ransomware will get worse before it gets better

The WannaCry outbreak put ransomware into the global spotlight, generating global coverage across mainstream media outlets as the malware epidemic locked governments, hospitals, public transport networks, factories and more out of their computer systems.

Thanks to its worm-like features, WannaCry was able to quickly spread itself across an infected network, taking advantage of a vulnerability in some versions of Windows. Over 300,000 Windows PCs succumbed to the ransomware before the outbreak was brought to a halt when a kill switch was discovered. But plenty of damage had already been done, with billions of potential revenue lost.
