TWINN #104 Hackers using Teams to control your computer

Our digital transformation is mostly complete for organizations that have survived and thrived over the last three years. Remote communication tools were key, including Microsoft Teams for many.

The Opal C1 4k Webcam is now available. I’ve been using one for a week, and my microphone experience was not good. Still, the camera functions, real-time filters, and overlays are quite impressive with true depth segmentation, so blurring the background does not pixelate as with zoom and teams’ built-in features.

The video version will begin again next week. Happy new year!
