This ransomware attack has the ability to spread itself inside the corporate networks without any user interaction, by misusing a known vulnerability in Microsoft Windows. Especially for the operating system which is still running on Windows XP or Windows 7. Microsoft has released the security patch in March 2017 for those operating systems, but the machines that do not yet applied the latest Windows security updates are at high risk.
