One million devices are still vulnerable to BlueKeep, a critical Microsoft bug with wormable capabilities. The bug was fixed during Microsoft s May Patch Tuesday Security Bulletin earlier this month.

A spike in scans for vulnerable systems was spotted over the weekend potentially indicating that bad actors are looking to sniff out the activity.
