Example command (Linux):
While no known “wormable” Spectre exploits exist in the wild, it remains a blueprint for transient‑execution attacks and continues to inspire new variants (e.g., Spectre‑BHB, Retbleed). spectre 10
is a hardware vulnerability that affects modern microprocessors using branch prediction and speculative execution . It breaks the isolation between different applications by forcing a victim program to speculatively execute operations that would not occur during correct program execution. This speculative execution leaves measurable traces in the CPU’s cache, allowing an attacker to leak sensitive information (e.g., passwords, cryptographic keys) from kernel memory or other processes. spectre 10
The CPU uses a and Pattern History Table (PHT) to guess direction/target. Spectre poisons these predictors to cause the victim to speculatively execute attacker-controlled code. spectre 10
