Key Facts
InjectEave researchers describe a class of electromagnetic side-channel attacks that uses an external RF signal to induce leakage of low-frequency analog information. They evaluated the technique on 11 commercial devices across five categories.
Technical Details
The research attributes the leakage path to hardware nonlinearities. Its evaluation includes headphones, a VoIP phone, smart fans, and lamps; the authors report recovering private audio or determining appliance states without modifying the devices.
Impact & Mitigation
The research is a physical-proximity threat model, not a Wi-Fi or Bluetooth vulnerability. Treat sensitive discussions and devices in high-risk locations accordingly, and monitor vendor guidance for affected hardware where available.
