Cybersecurity researcher Mordechai Guri from Israel’s Ben Gurion University of the Negev recently demonstrated a new kind of malware that could be used to covertly steal highly sensitive data from air-gapped and audio-gapped systems using a novel acoustic quirk in power supply units that come with modern computing devices.

Dubbed ‘POWER-SUPPLaY,’ the latest research builds on a series of techniques leveraging electromagnetic, acoustic, thermal, optical covert channels, and even power cables to exfiltrate data from non-networked computers.
