A vulnerability in Microsoft's Windows 10 operating system could allow cybercriminals to breach or spy on computer networks if exploited, according to the National Security Agency and cited by The Wall Street Journal.
The NSA discovered the flaw in the digital signatures Microsoft uses to help prevent malware from being downloaded on a computer. If exploited, the flaw would allow hackers to download malware on the computer without being detected.
Microsoft released a patch for the vulnerability Jan. 14 and is recommending those using Windows 10 update their operating systems immediately. The Department of Homeland Security also issued an emergency directive Jan. 14, telling federal agencies to update their systems immediately.
For users who have automatic updates, the patch for the vulnerability has been installed, confirmed Jeff Jones, a Microsoft senior director, in a statement to WSJ.
