Game Console Security and Implications on General Computing
summary
Early console hacks are concrete: a modified Xbox save image causes a buffer overflow and drops a Linux kernel into the box, and a 360 “glitch” taps CPU buses, momentarily drops a voltage and bypasses signature checks — the exploit later appears as an $80 solder-on chip. Modern risks include unified GPU/CPU memory allowing shader-to-CPU code injection, cache side‑channel leaks of keys (Meltdown/Spectre style), and ML‑driven kernel‑driver bug finding. Defenses: on‑die FPGAs, physically unclonable functions, microkernels and formal proofs via Isabelle.
