WannaCry has changed our lives, if we have learned something after this ransomware attack is that we have to keep our software up-to-date, it seems that people are doing the homework slowly.
People could think that keep the software up-to-date it is a very simple task but nothing could be further from the truth actually it has turned into a nightmare for IT departments when you have to manage dozens/hundreds or even worse thousands of devices we have to plan it carefully.
Once again the simplest way to do this is aware our employees, teammates, etc about the importance of update the software because updating the software we will be "less" vulnerable, so please do not hesitate to update your software asap.
The DoublePulsar infections are continuously going down which indicates that people aren't using the publicly-available code released by the Shadow Brokers against Internet-accessible SMB. Theoretically, all Windows devices running SMB should be patched by now and therefor no longer vulnerable to the issues in MS17-010. If that were the case it would explain the lack of DoublePulsar propagation. However, there are still at least 91,081 devices vulnerable to MS17-010 which means that there remains a significant exposure of vulnerable SMB services on the Internet
