RadEar: A Self-Supervised RF Backscatter System for Voice Eavesdropping and Separation

This collection of recent arXiv submissions includes multiple items with clear security and privacy implications. Most notable: (1) “RadEar” demonstrates a covert RF backscatter system (batteryless tag + external reader) capable of through-wall voice eavesdropping and separation using energy-efficient dual-resonator modulation and self‑supervised voice-separation models — a practical privacy/physical-layer surveillance threat. (2) An Internet-scale measurement study of React2Shell exploitation documents active post-disclosure exploitation of a critical React Server Components remote code‑exec:
