If you're running Windows 10 on your PC, you might want to download and install the free security patch that was released on Tuesday.
The National Security Agency discovered a way for hackers to get into the more than 900 million computers using Microsoft's operating system, alerting the company so a fix could be made.
According to the feds, "the consequences of not patching the vulnerability are severe and widespread."
Anne Neuberger, the head of the NSA's Cybersecurity Directorate, made a point to note that they have not taken advantage of the bug, says Wired.
