New RAMBO attack steals data using RAM in air-gapped computers

RAMBO (Radiation of Air-gapped Memory Bus for Offense) is a research demonstration of a covert electromagnetic exfiltration technique where malware manipulates RAM access patterns to generate modulated emissions that can be received by an SDR; the paper reports throughput up to ~1,000 bps (suitable for small secrets like keystrokes or keys), effective ranges up to several meters depending on speed, and recommends mitigations including physical zoning, EM/RAM jamming, and Faraday shielding.
