It's a fine word, in and of itself. It’s easy to reach for, understandable to everyone… and it's the wrong one, most of the time. So, story time. Last year I gave an interview with the amazing Hazel Burton about VPNFilter, and my run-in with burnout. I was a manager during that time, and it took a toll on me and…

The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless. But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running…
