POPULAR SCIENCE — The next generation of attacker may have more in common with a cat burglar than a code monkey. They slip physically close to a target instead of typing their way in. Some of the sharpest new attacks skip the login screen entirely. They reach straight into the hardware, sometimes from the other side of a wall.
The researchers behind the discovery are led by Prof. Han Jun of KAIST, working with researchers from the National University of Singapore and Zhejiang University in China.
At NDSS (Network and Distributed System Security) 2026, they demonstrated that an antenna trained on a running computer can capture the faint electromagnetic leakage from its GPU.
