The hype over the WannaCry ransomware attacks in mid-May that ultimately disrupted 300,000 systems in over 150 countries has died down. Nonetheless, it is thought to be the largest ransomware attack recorded to date; taking the British National Health Service as one of its first and most severely assaulted victims.
2016 saw a surge in ransomware attacks. There were four times as many total attacks as in 2015. In 2017, the problem will get worse with experts estimating there will be a 25% increase in new ransomware families, providing more opportunities for hackers.
