The level of attacks seems definitely to be ramping up. I think the main reason for this jump has been the fact attackers are starting to make significant money out of these attacks now - especially now they can accept funds easily via Bitcoin. Before I think attacks were mainly for the lulz or very sophisticated attackers with various goals, but there must be hundreds of millions of dollars in ransoms being paid out now. Nearly anyone can now start making very good money with some simple tools. And like any business people start innovating a lot quicker with a profit motive.
