Microsoft issued a fix for a recently discovered flaw in Microsoft’s Remote Desktop Protocol service on May 14. A security researcher warns 950,000 unpatched devices running older versions of Microsoft Windows remain vulnerable to the flaw. The vulnerability, called BlueKeep, was first spotted by the U.K.’s National Cyber Security Center. Microsoft says it’s seen no evidence of the flaw being exploited in the wild, but warns attackers could develop a robust exploit within the coming weeks. Newer versions of Windows, including Windows 8 and Windows 10, are not affected.”]
