On Tuesday, October 14, 2014, iSIGHT Partners and Microsoft announced a Zero-Day vulnerability named “Sandworm” found in all versions of Microsoft Windows and Windows Server 2008 and 2012.
The vulnerability has been exploited in a small number of cyberespionage attacks against NATO, energy companies, a US academic organization and many others. Microsoft has since created a patch and released it as one of their security updates (CVE-2014-4114.).
If you have enabled automatic updating, the Microsoft security update will be downloaded and installed automatically. If you have not, it is critical that you run the security update from Microsoft, as well as all other important security updates through the Windows Updater immediately.
