Can hackers steal your information even if your webcam is covered?

That tape on your webcam may not be enough: Hackers are watching; it might be a good time to install another privacy shutter.

In a report just published in Science Advances, MIT researchers highlighted the image privacy risks that ambient light sensors can offer. Device users concerned about security can find comfort in software permissions that limit webcam use and hardware solutions like shutters. However, studies have shown that one of the typical ambient light sensors used in a variety of devices can be used to collect visual data. These tiny sensors are normally permissionless at the device level and are not closed or disabled by users.
