ODINI Malware Uses CPU Magnetic Emissions to Breach Faraday-Shielded Air-Gapped Computers

ODINI is a proof-of-concept covert-channel malware that exfiltrates data from air-gapped systems by deliberately modulating CPU workloads to generate low-frequency magnetic fields that penetrate Faraday cages; a related MAGNETO variant uses infected smartphones' magnetometers as receivers. The report (Ben-Gurion University research) details modulation methods, transmission ranges and rates, required receiver proximity, and defensive options such as mu-metal shielding, magnetic jamming, software-based workload jamming, and strict physical device zoning.
