- Optical fibers, known for reliability, are shown to have a side channel enabling acoustic eavesdropping.
- Attackers can exploit sensitivity to acoustic vibrations to remotely monitor sounds and recover information like conversations.
- This threat is heightened by FTTH proliferation, where attackers with fiber access can use DAS systems for privacy breaches.
- A 'Sensory Receptor' is introduced to enhance acoustic capture, as fiber alone is insufficient for airborne sound.
