Usable data hacked from air-gapped computer

Attack demonstration. An air-gap workstation processes a secret image (Optimus Prime) 

The RAMBO covert channel attack transmits the image via electromagnetic waves. A remote attacker intercepts the information and recovers the secret image. Credit: arXiv (2024). DOI: 10.48550/arxiv.2409.02292

A team of software and information systems engineers at Ben-Gurion University of the Negev, in Israel, has demonstrated an ability to extract useful data from an air-gapped computer. The group has posted a  to the  preprint server describing their experiments and results.
