Hackers hope to democratize laser-based processor hacking — $500 RayV Lite relies on 3D printing, a laser pen, and a Raspberry Pi to bring costs down

… “The first of two versions of the RayV Lite will focus on laser fault injection (LFI). This technique uses a brief blast of light to interfere with the charges of a processor’s transistors, which could flip them from a 0 value to a 1 value or vice versa. Using LFI, Beaumont and Trowell have been able to pull off things...
