GPT-4: Researchers have discovered a novel attack that recovers secret encryption keys from smart cards and smartphones by using cameras to record power LEDs during cryptographic operations. This technique provides a new way to exploit previously disclosed side channels, removing the need for specialized instruments or proximity to the targeted device. The groundbreaking research demonstrates the potential for side-channel attacks to be facilitated through video-based methods, posing a significant security risk.
