That viral "air-gapped data exfiltration" paper only read temperature over a 4cm gap
basedjensen · x · 2026-09-18
The author debunks a viral paper: it doesn't demonstrate data transmission, only proposes a method; the actual experiment reads a temperature signal across a 4cm gap in a lab setting. Real transmission requires sender and receiver agreeing on medium and protocol — one-sided "data transmission" isn't a thing, so this is neither a practical nor an effective side channel.
