Security News > 2020 > June > Three years after WannaCry, what have we learned?

Three years ago, the WannaCry ransomware worm wreaked havoc on hundreds of thousands of organizations worldwide, ranging from hospitals that had to pause urgent operations to multinational delivery services that were forced to halt the transportation of goods.

Three years later, the memories are still fresh in our minds - but have organizations applied any of the lessons learned to their overall security strategy? Let's take a look.

In 2017, WannaCry compromised out-of-date, unpatched computers and servers, encrypting data on systems and shutting organizations down completely.

Fast forward to today and for those numerous organizations that still have not patched old Windows systems, WannaCry remains a threat to some extent.

Some lessons have been learned by organizations of all sizes and sectors.
