Homeland Security’s cybersecurity advisory unit is warning Windows 10 users to make sure that their systems are fully patched, after exploit code for a “wormable” bug was published online last week.

The code takes advantage of a security vulnerability patched by Microsoft back in March. The bug caused confusion and concern after details of the “critical”-rated bug were initially published but quickly pulled offline.
