Revolutionizing Laser Hacking with RayV Lite
Beaumont describes RayV Lite as part of a larger trend she calls “tool localization,” aiming to make laser hacking more affordable and accessible. As Adam Laurie, a renowned hardware hacker, points out, this technology is shifting from exclusive academic domains to the DIY community.
Laser Fault Injection: Disrupting Processor Transistors
In their development of RayV Lite, Beaumont and Trowell focused on two laser hacking approaches. Laser Fault Injection (LFI) involves using light bursts to disrupt processor transistors, altering their charge and potentially compromising security measures. This technique has shown success in accessing sensitive information from chips, including automotive and cryptocurrency wallets.
Laser Logic State Imaging: Real-time Monitoring of Processor Activity
Another key aspect of laser hacking is laser logic state imaging, which enables real-time monitoring of a wafer’s architecture. By analyzing how laser light reflects off the silicon, hackers can map the processor’s layout and extract valuable data. The use of machine learning tools enhances the precision of this technique, allowing for detailed insights into chip functionalities.
