Hackers behind this attack has been using EthernalBlue, an exploit developed by the NSA to identified flaws in Microsoft SMB protocol, and which was leaked in the dark web by a hacking group called Shadow Brokers. Microsoft released an update to patch the vulnerability on its newer version in March. Many users and administrators have failed to apply the updates, making it easier for the ransomware to spread more quickly. As many small businesses and individuals are still using older version of operating system, Microsoft took an unusual step by releasing updates for Windows XP, Windows 8, and Windows Server 2003 so that all users can patch their system.
We advise our readers to apply the patch released by Microsoft as soon as possible and not to open any files received from an unknown source.
