The Unfixable Apple CPU Bug: A Deep Dive into Cache-Based Side Channel Attacks
In the world of offensive security, a new and alarming bug has emerged, affecting the Apple M1, M2, and M3 chipsets. This bug, known as "Go Fetch," is a vulnerability in the silicon design of the CPU, making it virtually unpatchable without physically replacing the affected hardware.
The bug is a local vulnerability, meaning an attacker must already have access to the target computer to exploit it. However, the implications of this bug are far-reaching, as it delves into the realm of side-channel cache-based memory attacks, a field that has been an active area of research and exploitation for the past decade.
