Welp, another Windows worm is on the loose and spreading like wildfire through unpatched systems. It can infect USB thumbdrives and mutate itself.
All-time top security tip #1: patch, patch, patch!
If you are a home user, set your Windows updates to automatically download and install.
If you are an IT professional, have a patching system in place to ensure all machines get patched in a timely manner. This worm just goes to show that the task of ensuring systems are patched cannot grind to a halt even during the holidays. At least one person has to keep their eye on the ball at all times. It sucks, especially if you’re at a smaller organization and you’re the only IT person, but that’s the nature of the beast.
Stay safe out there.
