Why
Existing operating systems are insufficient for detailed microarchitectural security research due to instability and interference, prompting the need for a dedicated tool to study hardware behavior directly.
The Frontline Impact

How this affects you

The findings challenge previous understanding of M1 security, demonstrating a need for re-evaluation of current security assumptions in Apple Silicon, and provide a new, more reliable tool for microarchitecture research across the industry.
