PowerHammer’ exploit can steal data from PCs and other systems through electrical lines. Researchers at Ben-Gurion University of the Negev in Israel have created a new exploit. Previously, researchers came up with ways to get air-gapped computers to give up data through means such as noise emitted by hard drives and fans, heat emissions and other physical means. This time, the data is leaking out the electrical line that is powering the machine. The attack establishes two frequencies to represent a “1” bit and a “0” bit.”]
