WannaCrypt/WCry is a ransom-ware worm that can attack most versions of Windows. It has made headlines by catching out various large organisations such as the NHS.
End-users and small companies need not panic as Microsoft issued a patch for all supported versions of Windows back in March; so make sure Windows Update is enabled and up to date.
Due to the intensity of the attacks last week, they have also just released a patch for the otherwise unsupported Windows XP, Server 2003 and Windows 8.
If you are using an non-supported version of Windows or you want more information then go to the following page for guidance: https://www.ncsc.gov.uk/news/latest-statement-international-ransomware-cyber-attack-0
