Where
Cambridge, Massachusetts, United States ·
Why
Fractal was built because existing operating systems are unstable and difficult to reproduce for the level of detailed chip analysis needed to identify vulnerabilities like Spectre and Meltdown.
The Frontline Impact
How this affects you
This new operating system provides a "clean room" for chip research, allowing for more precise identification of vulnerabilities like Phantom attacks on Apple Silicon, which could lead to enhanced security measures for processors.
