Revolutionizing Laser Hacking with RayV Lite
Beaumont describes RayV Lite as part of a larger trend she calls “tool localization”. The ChipWhisperer and HackRF have made electromagnetic or radio-based hacking more affordable and accessible. Now, with RayV Lite, she hopes to bring the same level of accessibility to laser hacking.
Laser Fault Injection: A Game-Changing Technique
One of the key approaches that Beaumont and Trowell focused on with RayV Lite is Laser Fault Injection (LFI). This technique involves using brief bursts of light to disrupt the charge in processor transistors, leading to significant impact. For example, by glitching an automotive chip with a laser, Beaumont was able to circumvent security checks and access otherwise protected information.
Laser Logic State Imaging: Unveiling the Secrets of Processors
Another crucial aspect of laser hacking technology is laser logic state imaging. This technique allows real-time monitoring of a wafer’s architecture and activity by bouncing laser light off the wafer and analyzing the results using machine learning tools. By mapping the physical layout and data stored in transistors, hackers can extract valuable insights about the chip’s data and code.
