Google’s Project Zero, a team finding security flaws in it’s own products as well as other firms, exposed high severity flaw in macOS kernel.

Team reported that when user-owned mounted filesystem image is modified, the virtual management subsystem is not informed of the changes, making attackers able to take malicious actions without the mounted filesystem knowing about it. For full report, click here.

Also, Project Zero generally report the problems to the manufacturers privately and give them 90 days to resolve the problem before publicly disclosing it, which means that Apple couldn’t — or didn’t — fix the flaw for 90 days.

Researchers from Massachusetts Institute of Technology invented new technology that can beam sounds to a specific person using a laser. It works by using eye-safe laser which heat the water molecules in the air, creating a local sound.

Currently, the tech can send sounds up to 60 decibels with a distance of roughly 2.5 meters. But the team are working to make measurements longer, 100 to 500 meters.
